This commit implements a `singleLicensePer` option, which allows an application to tell the RxPlayer that the current content only has a single license for the whole content, even when it has multiple keys associated to different tracks or qualities. The RxPlayer will then be able to perform a single license request and, if the right options are set, to fallback from non-decryptable contents, which will be both: 1. keys which have the wrong key-status ("output-restricted" if `fallbackOn.keyOutputRestricted` is set and "internal-error" if `fallbackOn.keyInternalError` is set). 2. keys which were not included in that license. Those will be fallbacked from, without needing to set any API. The idea is also to be able to make evolutions to that API to implement for example a single license per Period in the future. ### Why doing that? The idea here is to perform a single license request, initially for a single quality, which will in response return a license (technically it could be multiple concatenated licenses in the CDM's point of view depending of the key system, but it is still a single request and data structure in the player's point of view) allowing to decrypt all encrypted media from that same content. The advantages of doing that are multiple. Most of all: 1. it allows to only perform a single license request instead of multiple ones. Reducing possible server loads but also reducing network latencies. 2. We could be able to tell much sooner which key are not supported and thus avoid switching to an undecipherable Representation to only later fallback from it. 3. some other players not being compatible with contents necessitating multiple license requests, putting all keys in a single license can improve compatibility for when streams are used with multiple players. 4. it reduces interactions with EME APIs, which we found to be very slow on some devices (we for example found out that generating a challenge can take more than 1 second on some embedded devices). And surely many others. Before that commit, the RxPlayer would already play those contents, but would still perform multiple license requests reducing the potential gains. ### What it means technically Technically, the description of this feature is simple: When `singleLicensePer` is set to `"content"`: - we should only perform a single license request, event when there's multiple initialization data encountered in the MPD and initialization segments - we should fallback from `Representation`s whose corresponding key ids are either: 1. Not signaled in the license 2. Signaled in the license but have to be fallbacked from according to the `fallbackOn` options ## Implementation ### Re-purposing `handledInitData` To implement that, the main idea is to re-purpose the `handledInitData` cache (in the `EMEManager`), which stores initialization data that has already been encountered. The only goal of that structure before being to avoid creating multiple MediaKeySessions for the same initialization data, it isn't a stretch to redefine it as a structure avoiding creating multiple MediaKeySessions linked to the same key ids. I changed the way it is used in two ways: 1. When `singleLicensePer` is set to `"content"` we can simply check when it's empty to only create a session on the first initialization data encountered (we can imagine also adding several IDs to that structure to easily implement `"period"` etc.). 2. As we still need to fallback from any initialization data that has no corresponding key in the license when the latter is loaded, I had to add to that structure an Observable emitting `"blacklisted"` key ids from the corresponding `MediaKeySession` and the other key ids, now considered by opposition as `"whitelisted"`. Simply said, every key ids linked to a MediaKeySession which are not present blacklisted (because of the usual `fallbackOn` options) will be whitelisted. By listening to that Observable everytime new initialization data is encountered, we can just compare the linked key id with whitelisted key ids that Observable emits - which will be once the license is pushed. If the license has already been pushed, the Observable will emit immediately. ### Adding the key id to `contentProtections$` event Because we are using key ids here to detect which keys are not in a given license, we have to emit those alongside the initialization data to the `EMEManager`. This is done through the already-existing `contentProtections$` Observable. In the hypothesis that no key id is anounced in the Manifest, we may thus have to parse initialization data to extract it from there, so we can support multi-key per license mode with such contents. This is not done here for the moment, but I'm working on it now. In the meantime, initialization data for which the corresponding key id is not known will still lead to another license request, which I felt was a good compromise. ## Does it work? I tested it with success on: - Widevine L1 on STBs - Widevine L3 on Linux - Chrome - Widevine L3 on Linux - Firefox - Widevine L3 on Mac - Chrome - Widevine L3 on Windows - Edge - PlayReady SL3000 on Windows - Edge I know it doesn't work yet on some set-top boxes, but this seems more an exception than the norm. We've still scheduled a meeting to learn more about this issue. Depending on the result, we may want to perform updates on that code. --- src/core/eme/check_key_statuses.ts | 17 +++- src/core/eme/eme_manager.ts | 91 ++++++++++++----- src/core/eme/session_events_listener.ts | 37 +++---- src/core/eme/types.ts | 106 +++++++++++++++++--- src/core/eme/utils/loaded_sessions_store.ts | 17 +++- src/core/init/initialize_media_source.ts | 4 +- src/core/init/types.ts | 6 +- src/manifest/index.ts | 7 +- src/manifest/representation.ts | 28 +++--- 9 files changed, 225 insertions(+), 88 deletions(-) diff --git a/src/core/eme/check_key_statuses.ts b/src/core/eme/check_key_statuses.ts index ddb9239cae..1e9aa092bf 100644 --- a/src/core/eme/check_key_statuses.ts +++ b/src/core/eme/check_key_statuses.ts @@ -48,22 +48,26 @@ export interface IKeyStatusesCheckingOptions { /** * Look at the current key statuses in the sessions and construct the - * appropriate warnings and blacklisted key ids. + * appropriate warnings, whitelisted and blacklisted key ids. * * Throws if one of the keyID is on an error. * @param {MediaKeySession} session - The MediaKeySession from which the keys * will be checked. * @param {Object} options * @param {String} keySystem - The configuration keySystem used for deciphering - * @returns {Array} - Warnings to send and blacklisted key ids. + * @returns {Array} - Warnings to send, whitelisted and blacklisted key ids. */ export default function checkKeyStatuses( session : MediaKeySession | ICustomMediaKeySession, options: IKeyStatusesCheckingOptions, keySystem: string -) : [IEMEWarningEvent[], Uint8Array[]] { +) : { warnings : IEMEWarningEvent[];

This worked pretty well, but we found a persistence-related issue that could profit from taking another strategy: After loading a persistent MediaKeySessions (that has previously been added to the `PersistentSessionsStore`), the RxPlayer immediately checks the status of its keys through the `keyStatuses` property. However, on some platforms, the `keyStatuses` property is not directly populated once the `load` call is done, but only after a difficult-to-predict delay (sometimes immediately after, sometimes more than 10 milliseconds after). This imply that we might now have to wait after loading a persistent session just to be sure that all keys information have been added to it. We limited that by only waiting a delay if the `keyStatuses` property is empty, yet this pre-condition was frequent: any time the user loaded a new content before the license request succeeded (but after the `generateRequest` call) we would be legitimately in a case where the `keyStatuses` property is actually empty. To avoid penalizing too much legitimate cases, this commit adds a persistent session to the `PersistentSessionsStore` only once at least one key is added to its `keyStatuses` property. This ensures that having an empty `keyStatuses` property will now be unusual enough. In that case, incurring a delay (let's say up to 100ms) will be much less penalizing. --- src/core/eme/eme_manager.ts | 38 ++++++++++++++++++++++++------------- 1 file changed, 25 insertions(+), 13 deletions(-) diff --git a/src/core/eme/eme_manager.ts b/src/core/eme/eme_manager.ts index 5e65349ca7..7721c7a2cf 100644 --- a/src/core/eme/eme_manager.ts +++ b/src/core/eme/eme_manager.ts @@ -245,6 +245,13 @@ export default function EMEManager( const { mediaKeySession, sessionType } = sessionEvt.value;

Representations which have their key-id added to one of the `MediaKeyStatusMap` linked to the current content and which are not fallbacked from, will now have their `decipherable` property updated to `true` - even if it was set to `false` before (and thus even if we had fallbacked from it in the past). This development was made a lot easier by the work done to support the `singleLicensePer` option (#904) with now the concept of "whitelisted key ids", in opposition of the "blacklisted key ids" we fallback from. When a key id is found to be whitelisted (technically this means currently that its `MediaKeyStatus` is not either: `"internal-error"`, `"output-restricted"` or `"expired"`, the last one depending on `keySystems options) we will now: - update the related `Representation`'s `decipherable` property to `true` - regardless of its previous state - schedule a `decipherabilityUpdate` event with that update through the API (and through the `Manifest` object with the event of the same name) - In the `AdaptationStream` - only if the updates changed the list of available Representations for that Adaptation, re-construct the list of the Representations the ABR has to choose from --- To note that this has never been tested in real conditions. --- src/core/init/initialize_media_source.ts | 3 +- .../stream/adaptation/adaptation_stream.ts | 2 +- .../create_representation_estimator.ts | 58 +++++++++++++----- .../orchestrator/get_blacklisted_ranges.ts | 3 + .../orchestrator/stream_orchestrator.ts | 14 ++++- src/manifest/adaptation.ts | 12 ---- src/manifest/manifest.ts | 60 +++++++++++-------- 7 files changed, 96 insertions(+), 56 deletions(-) diff --git a/src/core/init/initialize_media_source.ts b/src/core/init/initialize_media_source.ts index 1a4d1fd85e..313c66317d 100644 --- a/src/core/init/initialize_media_source.ts +++ b/src/core/init/initialize_media_source.ts @@ -328,8 +328,7 @@ export default function InitializeOnMediaSource( const setUndecipherableRepresentations$ = emeManager$.pipe( tap((evt) => { if (evt.type === "keys-update") { - log.info("Init: blacklisting Representations based on keyIDs"); - manifest.addUndecipherableKIDs(evt.value.blacklistedKeyIDs); + manifest.updateDeciperabilitiesBasedOnKeyIds(evt.value); } else if (evt.type === "blacklist-protection-data") { log.info("Init: blacklisting Representations based on protection data."); manifest.addUndecipherableProtectionData(evt.value); diff --git a/src/core/stream/adaptation/adaptation_stream.ts b/src/core/stream/adaptation/adaptation_stream.ts index 4109fbe3ab..edc23e755a 100644 --- a/src/core/stream/adaptation/adaptation_stream.ts +++ b/src/core/stream/adaptation/adaptation_stream.ts @@ -197,7 +197,7 @@ export default function AdaptationStream({ const bufferGoalRatioMap: Partial> = {}; const { estimator$, requestFeedback$, streamFeedback$ } = - createRepresentationEstimator(adaptation, abrManager, clock$); + createRepresentationEstimator(content, abrManager, clock$); /** Allows the `RepresentationStream` to easily fetch media segments. */ const segmentFetcher = segmentFetcherCreator.createSegmentFetcher(adaptation.type, diff --git a/src/core/stream/adaptation/create_representation_estimator.ts b/src/core/stream/adaptation/create_representation_estimator.ts index a372831415..c5536ebd95 100644 --- a/src/core/stream/adaptation/create_representation_estimator.ts +++ b/src/core/stream/adaptation/create_representation_estimator.ts @@ -15,12 +15,23 @@ */ import { + concat as observableConcat, merge as observableMerge, Observable, + of as observableOf, Subject, } from "rxjs"; +import { + distinctUntilChanged, + map, + switchMap, +} from "rxjs/operators"; import { MediaError } from "../../../errors"; -import { Adaptation } from "../../../manifest"; +import Manifest, { + Adaptation, + Representation, +} from "../../../manifest"; +import { fromEvent } from "../../../utils/event_emitter"; import ABRManager, { IABREstimate, IABRManagerClockTick, @@ -52,13 +63,14 @@ import { * information on what data is expected.

TextTrackRenderer

-

-

Overview

-

The TextTrackRenderer is a tool allowing to render subtitles synchronized with -a video element (or any HTMLMediaElement).

-

For now it supports the following formats:

-
    -
  • TTML
    • -
  • webVTT
    • -
  • srt
    • -
  • sami
    • -
-

The video does not need to be played through the RxPlayer for the -TextTrackRenderer to work. It is a completely independent tool which just -rely on the video element for synchronization information.

-

-

Brief summary

-

If you don’t want to read all this documentation, here is a complete example of -how it can be used:

-
// import TextTrackRenderer and the parsers we want
-import TextTrackRenderer, {
-  TTML_PARSER,
-  VTT_PARSER,
-  SRT_PARSER,
-  SAMI_PARSER,
-} from "rx-player/tools/TextTrackRenderer";
-
-// Add the needed parsers to the TextTrackRenderer
-TextTrackRenderer.addParsers([ TTML_PARSER, VTT_PARSER, SRT_PARSER, SAMI_PARSER ]);
-
-
-// get video element the subtitles has to be synchronized to
-const videoElement = document.querySelector("video");
-
-// get HTML element in which the text track will be displayed
-// Should generally be on top of the video, with the same size than it (but can
-// also be in any shape, corresponding to your UI needs).
-const textTrackElement = document.querySelector(".text-track-container");
-
-const textTrackRenderer = new TextTrackRenderer({
-  videoElement,
-  textTrackElement,
-});
-
-// example: a ".srt" track
-const exampleSRT = `1
-00:00:01,600 --> 00:00:04,200
-English (US)
-
-2
-00:00:05,900 --> 00:00:07,999
-This is a subtitle in American English
-
-3
-00:00:10,000 --> 00:00:14,000
-Adding subtitles is very easy to do
-`;
-
-try {
-  textTrackRenderer.setTextTrack({
-    data: exampleSRT,
-    type: "srt", // or "ttml" / "vtt" / "sami"
-    // timeOffset: 2.3, // optional offset in seconds to add to the subtitles
-  });
-} catch (e) {
-  console.error(`Could not parse the subtitles: ${e}`);
-}
-
-

-

How to import it

-

The TextTrackRenderer alone can be imported as such:

-
import TextTrackRenderer from "rx-player/tools/TextTrackRenderer";
-
-

But just importing the TextTrackRenderer alone is pointless, you also have to -import the text track parsers you want to use manually (this is a choice we -made to avoid wasting space for subtitles formats you might not want).

-

To import the parsers you want, you just have to do something along the line -of:

-
// Add two parsers to the TextTrackRenderer: one for TTML subtitles and one for
-// srt subtitles
-import TextTrackRenderer, {
-  TTML_PARSER,
-  SRT_PARSER,
-} from "rx-player/tools/TextTrackRenderer";
-TextTrackRenderer.addParsers([ TTML_PARSER, SRT_PARSER ]);
-
-

Here are the different available parsers:

- - - - - - - - - - - - - - - - - - - - - - - - - -
Import nameSubtitles format parsed
TTML_PARSERTTML
VTT_PARSERWebVTT
SRT_PARSERSubRip (.srt)
SAMI_PARSERSAMI
-

-

How to use it

-

-

Preamble

-

Now that it is imported, we can begin to use it.

-

We will need three items:

-
    -
  1. -

    The video element our subtitles has to be synchronized to.

    -
    2. -
  2. -

    Another HTML element, in which the various subtitles will be rendered by -the TextTrackRenderer. In general, you want that element to be on top of -the video element, with the same dimensions. You might however set it in -the shape and size you want.

    -

    It can even be reduced dynamically at any time (for example, to reduce this -element’s height when a UI element appear at the bottom of the screen, -thus avoiding the subtitles from overlapping that new element).

    -
    3. -
  3. -

    The whole text track data, as a string (you will have to download the -subtitles yourself).

    -
    4. -
-

To simplify, let’s give a name to all those 3 elements:

-
    -
  1. the videoElement
    2. -
  2. the textTrackElement
    3. -
  3. the textTrackData
    4. -
-

-

Creating a TextTrackRenderer

-

We first have to create a new TextTrackRenderer with the first two items:

-
const textTrackRenderer = new TextTrackRenderer({
-  videoElement,
-  textTrackElement,
-});
-
-

-

Setting a text track on it

-

With textTrackRenderer, the TextTrackRenderer instance, we can now add at -any time a text track through its setTextTrack method:

-
try {
-  textTrackRenderer.setTextTrack({
-    data: textTrackData,
-    type: SUBTITLES_FORMAT,
-  });
-} catch (e) {
-  console.error(`Could not parse the subtitles: ${e}`);
-}
-
-

Here, SUBTITLES_FORMAT is a string indicating in which format the subtitles -are. It can be any of those strings:

- - - - - - - - - - - - - - - - - - - - - - - - - -
typeCorresponding subtitles format
"ttml"TTML
"vtt"WebVTT
"srt"SubRip (.srt)
"sami"SAMI
-

(Each format needs the corresponding parser to be imported. See the previous -chapter for more information.)

-

Note that the setTextTrack method can throw if the subtitles are found to be -invalid.

-

Any subsequent call to setTextTrack will remove the current text track and -replace them with the new text track instead:

-
// Add TTML subtitles
-textTrackRenderer.setTextTrack({
-  data: textTrackData1,
-  type: "ttml",
-});
-
-// Completely removes the TTML subtitles and replace them by other subtitles, in
-// webVTT this time
-textTrackRenderer.setTextTrack({
-  data: textTrackData2,
-  type: "vtt",
-});
-
-

If your subtitles have a delay or are in advance relatively to the video, you -can also set an offset in seconds through the timeOffset property.

-

For example, this will display each subtitles 1.3 seconds later (for when -subtitles appear and disappear too much in advance):

-
textTrackRenderer.setTextTrack({
-  data: textTrackData,
-  type: "srt",
-  timeOffset: 1.3,
-});
-
-

And this will display each subtitles 1.3 seconds before they normally appear -and disappear (for when subtitles are too late):

-
textTrackRenderer.setTextTrack({
-  data: textTrackData,
-  type: "srt",
-  timeOffset: -1.3,
-});
-
-

-

Removing the current text track

-

If you just want to completely remove the current text track, you can call the -removeTextTrack method:

-
textTrackRenderer.removeTextTrack();
-
-

-

Disposing of the TextTrackRenderer

-

If you’re sure that you won’t need the TextTrackRenderer anymore, you can -dispose of most ressources (which is not much) it took on your page by calling -the dispose method:

-
textTrackRenderer.dispose();
-
-

That TextTrackRenderer instance won’t be usable once you’ve call this method, -so be sure you don’t need it anymore before calling it.

-

-

Notes on the SAMI format

-

The SAMI subtitles format might necessitate you to specify the language you want -to parse.

-

This can be done on the setTextTrack call like this:

-
textTrackRenderer.setTextTrack({
-  data: textTrackData,
-  type: "sami",
-  language: "en-US", // or fr-FR...
-});
-
-

-

About logs

-

The TextTrackRenderer can display logs to the console. It relies on the exact -same logger instance than the RxPlayer.

-

This logger can be independently imported from "rx-player/logger":

-
import logger from "rx-player/logger";
-
-

You can then set its verbosity through its setLevel method:

-
logger.setLevel(LOGGER_LEVEL);
-
-

LOGGER_LEVEL can be any of those strings (from the less verbose to the most):

-
    -
  • -

    "NONE": no log

    -
    • -
  • -

    "ERROR": unexpected errors (via console.error)

    -
    • -
  • -

    "WARNING": The previous level + minor problems encountered (via -console.warn)

    -
    • -
  • -

    "INFO": The previous levels + noteworthy events (via console.info)

    -
    • -
  • -

    "DEBUG": The previous levels + regular events (via console.log)

    -
    • -
-

⚠️ Updating the logger level will also update the RxPlayer’s logger -level as it is the exact same logger that is used there.

createMetaplaylist

-

createMetaplaylist is a function that allows to build a [metaplaylist] -(./metaplaylist.md) object from given contents information.

-

You may need to use this function because not all information about contents -are known by the user when wanting to create a metaplaylist. For example, -the end of a content will be found thanks to the content duration, that can be -parsed from the content manifest.

-

-

How to import it

-

createMetaplaylist is for now considered an “experimental” tool. This means -that its API could change at any new version of the RxPlayer (don’t worry, we -would still document all changes made to it in the corresponding release note).

-

As an experimental tool, it is imported as such:

-
import { createMetaplaylist } from "rx-player/experimental/tools";
-
-

You can then begin to use it right away.

-

-

How to use it

-

createMetaplaylist takes two arguments :

-
    -
  • -

    contentInfos (Array<Object>) : The list of content information, in the -playback order they should have in the metaplaylist.

    -

    The list is an array of objects with this attributes :

    -
      -
    • url (string): The URL of the source content
      • -
    • transport (string): The transport type of the content (dash, smooth -or even metaplaylist)
      • -
    -
    • -
  • -

    timeOffset (number|undefined) : the optionnal time offset that -applies to the metaplaylist start time (default is 0).

    -
    • -
-

Example:

-
createMetaplaylist(
-    [
-        // dash content, 10mn long
-        {
-            url: "https://somedashcontent.mpd",
-            transport: "dash",
-        },
-        // smooth content, 35s long
-        {
-            url: "https://somesmoothcontent.ism",
-            transport: "smooth",
-        },
-        // metaplaylist content, 100mn long
-        {
-            url: "https://somemetaplaylistcontent",
-            transport: "metaplaylist",
-        }
-    ],
-    1000
-)
-
-

The returned metaplaylist will look like :

-
    {
-        type: "MPL",
-        version: "0.1",
-        dynamic: false,
-        contents: [
-            {
-                url: "https://somedashcontent.mpd",
-                transport: "dash",
-                startTime: 1000,
-                endTime: 1600,
-            },
-            {
-                url: "https://somesmoothcontent.ism",
-                transport: "smooth",
-                startTime: 1600,
-                endTime: 1635,
-            },
-            {
-                url: "https://somemetaplaylistcontent",
-                transport: "metaplaylist",
-                startTime: 1635,
-                endTime: 7635,
-            },
-        ],
-    }

Deprecated APIs

-

This documentation lists APIs deprecated in the v3.x.x.

-

As we guarantee API compatibility in the v3.x.x, those API won’t disappear until -we switch to a v4.x.x version.

-

You will find here which APIs are deprecated, why, and depending on the -concerned API, how to replace it.

-

-

-

Fullscreen APIs

-

All fullscreen APIs have been deprecated, namely:

-
    -
  • the isFullscreen method
    • -
  • the setFullscreen method
    • -
  • the exitFullscreen method
    • -
  • the fullscreenChange event
    • -
-

This is because of several things:

-
    -
  • -

    fullscreen management has now become a lot more complex with features such -as advanced subtitles management, were the text track HTMLElement is -controlled by the application.

    -
    • -
  • -

    most application developpers also wants to put their own controls into -fullscreen mode. Those APIs only put the media element into fullscreen mode -and not any other element. This can be misleading.

    -
    • -
-

The fullscreen logic should now be entirely on the application-side. Replacement -code is provided for each of those APIs below.

-

-

-

Image (BIF) APIs

-

The following properties methods and events have been deprecated:

-
    -
  • the imageTrackUpdate event
    • -
  • the getImageTrackData method
    • -
  • the supplementaryImageTracks loadVideo option
    • -
-

This is because most code linked to image management will be moved outside the -RxPlayer. Doing that will both be more flexible for users and much easier to -maintain for us (albeit with a small time of transition for the application).

-

You can replace those API by this new exported function: -parseBifThumbnails.

-

To give more details about why those APIs have been deprecated, there are -multiple reasons:

-
    -
  1. How it should be specified for live contents of for multi-Period DASH -contents is not clear enough.
    2. -
  2. Integrating it in the RxPlayer’s API means that it had to take multiple -choices that we prefer to let to the application: whether to retry the -request if the it fails or if it is unavailable, whether to do the request -at all for users with a low bitrate…
    3. -
  3. The task of displaying those thumbnails is ultimately on the UI-side (the -part that know where the user wants to seek)
    4. -
  4. The biggest part of the code related to it was a simple BIF parser, that -can easily be re-implemented by any application.
    5. -
-

-

RxPlayer Methods

-

The following RxPlayer methods are deprecated.

-

-

getManifest

-

getManifest returns our internal representation we have of a given “manifest” -document.

-

Though it was first exposed to allow users to have access to more precize -information on the current content, this method also limited us on the possible -evolutions we could do, as changing what this function returns would mean -breaking the API.

-

We also realized that that method was not used for now by the implementation we -know of.

-

For now, we decided we will simply remove that API in the next major version. If -that’s a problem for you, please open an issue.

-

-

getCurrentAdaptations

-

getCurrentAdaptations returns an object describing each tracks available for -the current Period in the current content.

-

Like getManifest, we found that this API was not much used and limited us on -the possible evolutions we can do on the RxPlayer.

-

Again like getManifest, we plan to remove that API completely without -replacing it. -If that’s a problem for you, please open an issue.

-

-

getCurrentRepresentations

-

getCurrentRepresentations returns an object describing each “qualities” -available in the current chosen tracks.

-

Exactly like getCurrentAdaptations and getManifest, we found that this API:

-
    -
  • was not used as far as we know
    • -
  • limited the evolutions we could do on the RxPlayer’s code without breaking -the API.
    • -
-

We thus plan to remove that API completely without replacing it. -If that’s a problem for you, please open an issue.

-

-

getNativeTextTrack

-

getNativeTextTrack returned the first TextTrack element attached to the -media element or null if it did not exist.

-

This API was originally created to allow users to manipulate the TextTrack -element themselves. For example, to “catch” cues as they appear and display them -differently.

-

What changed is that we now have two text track modes:

-
    -
  • html, which allow advanced subtitle management
    • -
  • native, the old mode, which display subtitles natively through a -TextTrack element.
    • -
-

This API will only return an element for the native mode, but none for the -html mode because its element is not attached to the media element.

-

We heavily insist on people wanting advanced usecases to use the html mode, as -many formatting options do not work in native mode.

-

As we considered that getNativeTextTrack API was more confusing than it was -helpful in our current API, we decided to deprecate it. Do not hesitate to open -an issue if you use this API.

-

-

isFullscreen

-

isFullscreen has been deprecated as it is part of our Fullscreen APIs, see -the related chapter for more information.

-

isFullscreen just checked that ANY element was fullscreen. As such, it can -easily be replace for the majority of browsers with the following code:

-
function isFullscreen() {
-  return !!(
-    document.fullscreenElement ||
-    document.mozFullScreenElement ||
-    document.webkitFullscreenElement ||
-    document.msFullscreenElement
-  );
-}
-
-

-

setFullscreen

-

setFullscreen has been deprecated as it is part of our Fullscreen APIs, see -the related chapter for more information.

-

setFullscreen allowed to set the media element in fullscreen mode (or exit -fullscreen mode, if false was given as argument).

-

If you want to just put the media element on fullscreen mode, you can use the -following code:

-
function setFullscreen(goFull) {
-  if (goFull === "false") {
-    exitFullscreen();
-    return;
-  }
-  if (isFullscreen()) { // see code above
-    return;
-  }
-
-  const mediaElement = player.getVideoElement();
-  if (!mediaElement) {
-    throw new Error("No media element");
-  }
-  if (mediaElement.requestFullscreen) {
-    mediaElement.requestFullscreen();
-  } else if (mediaElement.msRequestFullscreen) {
-    mediaElement.msRequestFullscreen();
-  } else if (mediaElement.mozRequestFullScreen) {
-    mediaElement.mozRequestFullScreen();
-  } else if (mediaElement.webkitRequestFullscreen) {
-    mediaElement.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);
-  }
-}
-
-

Please consider however that this function will only put the media element in -full screen mode, without the eventual controls and HTML text tracks you might -also want to set in fullscreen. The code is easily adaptable however to put -your own element into fullscreen mode instead.

-

-

exitFullscreen

-

exitFullscreen has been deprecated as it is part of our Fullscreen APIs, see -the related chapter for more information.

-

exitFullscreen just exited any element put in fullscreen mode. As such, -its code can easily be replaced by:

-
function exitFullscreen() {
-  if (isFullscreen()) {
-    if (document.exitFullscreen) {
-      document.exitFullscreen();
-    } else if (document.msExitFullscreen) {
-      document.msExitFullscreen();
-    } else if (document.mozCancelFullScreen) {
-      document.mozCancelFullScreen();
-    } else if (document.webkitExitFullscreen) {
-      document.webkitExitFullscreen();
-    }
-  }
-}
-
-

-

getImageTrackData

-

getImageTrackData has been deprecated like most API related to BIF thumbnail -parsing. -You can read the related chapter for more information.

-

You can replace this API by using the -parseBifThumbnails tool.

-

-

RxPlayer Events

-

The following RxPlayer events has been deprecated.

-

-

nativeTextTracksChange

-

nativeTextTracksChange events are deprecated. Which means they probably -won’t be sent in a v4.x.x version.

-

The reasons are basically the same than for the getNativeTextTracks method. -It should not be needed anymore as most advanced needs should be better answered -by an html text track mode.

-

-

fullscreenChange

-

fullscreenChange events have been deprecated as it is part of our Fullscreen -APIs, see the related chapter for more information.

-

The fullscreenChange event was sent when the media element got in or out of -fullscreen mode, with agg boolean as a payload:

-
    -
  • if true, the element entered fullscreen mode
    • -
  • if false, the element exited fullscreen mode
    • -
-

This behavior can easily be recreated through the following code:

-
const mediaElement = player.getVideoElement();
-mediaElement.addEventListener("fullscreenChange", () => {
-  if (isFullscreen()) { // see isFullscreen implementation above
-    // do things
-  } else {
-    // do other things
-  }
-});
-
-

-

imageTrackUpdate

-

imageTrackUpdate events have been deprecated like most API related to BIF -thumbnail parsing. -You can read the related chapter for more information.

-

You can replace this API by using the -parseBifThumbnails tool.

-

-

loadVideo options

-

The following loadVideo options are deprecated.

-

-

defaultAudioTrack

-

The preferredAudioTracks loadVideo -option is now the preferred -(no pun intended) solution to set the default audio track. -This new option allows to handle much more complex use cases and can even be -updated at any time through the setPreferredAudioTracks -method.

-

How to replace that option

-

It is very easy to replace defaultAudioTrack by preferredAudioTracks.

-

For example, if you want to have a default french audio language, you probably -previously did:

-
player.loadVideo({
-  url: myURL,
-  transport: myTransport,
-
-  defaultAudioTrack: { language: "fra", audioDescription: false },
-  // or just `defaultAudioTrack: "fra"`, both are equivalent
-})
-
-

Now you will have to set it through an array either when creating a new -RxPlayer:

-
const player = new RxPlayer({
-  preferredAudioTracks: [{ language: "fra", audioDescription: false }],
-})
-
-

Or at any time, through the setPreferredAudioTracks method:

-
player.setPreferredAudioTracks([{ language: "fra", audioDescription: false }]);
-
-

-

defaultTextTrack

-

defaultTextTrack is replaced by the preferredTextTracks constructor -option for the same reason -than defaultAudioTrack.

-

How to replace that option

-

It is very easy to replace defaultTextTrack by preferredTextTracks.

-

For example, if you want to have a default swedish subtitle language, you -probably previously did:

-
player.loadVideo({
-  url: myURL,
-  transport: myTransport,
-
-  defaultTextTrack: { language: "swe", closedCaption: false },
-  // or just `defaultTextTrack: "swe"`, both are equivalent
-})
-
-

Now you will have to set it through an array either when creating a new -RxPlayer:

-
const player = new RxPlayer({
-  preferredTextTracks: [{ language: "swe", closedCaption: false }],
-})
-
-

Or at any time, through the setPreferredTextTracks method:

-
player.setPreferredTextTracks([{ language: "fra", closedCaption: false }]);
-
-

-

supplementaryTextTracks

-

The supplementaryTextTracks has been deprecated for multiple reasons:

-
    -
  1. -

    The main reason is that the behavior of this API is not defined for -multi-Period DASH contents (nor for MetaPlaylist contents): Should we only -add the subtitles for the first Period or should it be for every Period? -How to define a different subtitles track for the first and for the second -Period?

    -

    Adding an external tool much less coupled to the RxPlayer move those -questions entirely to the application, which should know more than us what -to do in those different cases.

    -
    2. -
  2. -

    Its API was a little arcane because we had to make it compatible with every -possible type of contents (i.e. DASH, Smooth, MetaPlaylist etc.) out there.

    -
    3. -
  3. -

    It did not work for Directfile contents yet. Although we could have made it -compatible with them, we thought that this was the occasion to define a -better API to replace it.

    -
    4. -
  4. -

    Its behavior was more complex that you would initially think of. For -example, we could have to re-download multiple times the same subtitles -file if manual garbage collecting was enabled.

    -
    5. -
  5. -

    All usages of that API that we know of were for Smooth or DASH VoD contents -which sadly just omitted those subtitles tracks in their Manifest. The true -“clean” way to fix the problem in that case is to do it at the source: the -content. -In this case, fixing it on the player-side should only be a temporary -work-around (don’t be scared, we still have an API replacement).

    -
    6. -
-

The new TextTrackRenderer tool which replace it is much more straightforward. -As an external tool which just reads and renders already-downloaded text -subtitles, its API and the extent of what it does should be much more simple.

-

It’s also compatible with any type of contents, even when playing through an -other player.

-

How to replace that option

-

Every supplementaryTextTracks feature can be replaced by the -TextTrackRenderer tool. -Please bear in mind however that they are two completely different APIs, doing -the transition might take some time.

-

The TextTrackRenderer tool is documented here.

-

-

supplementaryImageTracks

-

The supplementaryImageTracks events have been deprecated like most API related -to BIF thumbnail parsing. -You can read the related chapter for more information.

-

You can replace this API by using the -parseBifThumbnails tool.

-

-

hideNativeSubtitle

-

The hideNativeSubtitle option is deprecated and won’t be replaced.

-

This is because it was added at a time when our text track API was much less -advanced. Some applications wanted to handle subtitles themselves and thus hid -the true “native” subtitles to display them themselves in a better way.

-

However, this API seems to not be used anymore. Please open an issue if you need -it.

-

-

RxPlayer constructor options

-

The following RxPlayer constructor options are deprecated.

-

-

throttleWhenHidden

-

throttleWhenHiddenhas been deprecated as video visibility relies only on -page visibility API and document hiddenness.

-

A video should be visible if the Picture-In-Picture mode is activated, even -if the hidden attribute of document is set to true.

-

throttleVideoBitrateWhenHidden relies on both and can be used like this :

-
const rxPlayer = new RxPlayer({
-  // ... RxPlayer options
-  // throttleWhenHidden: true [deprecated]
-  throttleVideoBitrateWhenHidden: true,
-});
-
-

-

Other properties

-

Some very specific properties from various methods are deprecated. -You will find them here.

-

-

Manifest

-

The adaptations property returned by the Manifest object you can obtain -through the getManifest call is deprecated.

-

This corresponds to the adaptations property of the first element in the -periods object from the same Manifest object, so it’s very easy to -replace:

-
const manifest = player.getManifest();
-
-if (manifest && manifest.periods.length) {
-  console.log(manifest.adaptations === manifest.periods[0].adaptations); // true
-}
-
-

-

Smooth

-

Setting a *.wsx, a *.ism or a *.isml URL as an url property in -loadVideo is now deprecated when we’re talking about a Smooth Streaming -content.

-

We recommend to only set a Manifest URL in that property when the transport is -equal to smooth.

-

-

NetworkError

-

The xhr property from a NetworkError is deprecated.

-

This is to prepare the support of low-latency streaming, with -CMAF, -where the fetch API has to be used instead of an XMLHttpRequest.

-

We recommend to not rely on this property anymore. You still should have access -to the status and url properties.

Player errors and warnings

-

-

-

Overview

-

Various errors can be triggered when playing a media content. Those can happen -when:

-
    -
  • The network is unreachable
    • -
  • The codecs are not supported
    • -
  • We have no mean to decrypt the data
    • -
  • …
    • -
-

Some errors can be fatal to content playback in which case they will stop the -player, others act more as warnings and are more along the line of a minor -problem notification.

-

You can know if a fatal error interrupted your playback by:

-
    -
  • -

    adding an event listener to the "error" event (see the player events -documentation). This event listener will take the error -directly in argument.

    -
    • -
  • -

    calling the getError API if the current state is STOPPED. If -different from null, it means that a fatal error happened (see the -documentation for getError).

    -
    • -
-

You can also be warned of any non-fatal error by:

-
    -
  • adding an event listener to the "warning" event (see the player events -documentation). The event listener will take the -non-fatal error directly in argument.
    • -
-

All of those are in essence Error instances with added information.

-

Those supplementary information are described in this page.

-

-

-

Structure of an Error

-

Each of RxPlayer’s error objects have at least those properties:

-
    -
  • -

    type (string): A large category for the error -(e.g. NETWORK_ERROR, ENCRYPTED_MEDIA_ERROR …)

    -
    • -
  • -

    code (string): A set identification “code” for the error encountered

    -
    • -
  • -

    message (string): A displayable, human-readable, summary of the -error.

    -
    • -
  • -

    fatal (boolean): If true, the error was fatal. Meaning that the -playback was interrupted by it

    -
    • -
-

-

-

Types

-

The types are the different strings you can have as the type property of an -error.

-

This chapter provides an exhaustive list of the possible type of error -encountered.

-

-

-

NETWORK_ERROR

-

A NetworkError is any Network-related error (HTTP 404, request timeout…), they -all have a type property equal to "NETWORK_ERROR".

-

codes

-

A NetworkError can only have the following code (code property):

-
    -
  • "PIPELINE_LOAD_ERROR": the Manifest or segment -request failed.
    • -
-

more information

-

A NetworkError provide much more infos than this code.

-

Among its properties, you have:

-
    -
  • -

    url (string): The url the request has been on

    -
    • -
  • -

    status (Number): Shortcut to the status code of the xhr.

    -
    • -
  • -

    errorType (string): Further precision about what went wrong.

    -

    This string can either be:

    -
      -
    • "TIMEOUT": The request timeouted.
      • -
    • "ERROR_EVENT": The XMLHttpRequest has sent an error event
      • -
    • "PARSE_ERROR": No data could have been extracted from this request
      • -
    • "ERROR_HTTP_CODE": The request finished with a status code not in -the 2xx range.
      • -
    -
    • -
  • -

    code (number): The HTTP code of the request at the time of the -error (0 if no request has been done yet)

    -
    • -
  • -

    xhr (XMLHttpRequest|undefined): The xhr associated with the request. -Not defined if the current content has been launched in lowLatencyMode.

    -

    Note: This last property is deprecated. It will disappear in the next major -release, the v4.0.0 (see Deprecated APIs).

    -
    • -
-

-

-

MEDIA_ERROR

-

Error related to the media itself. It can both come from the player itself -(Manifest parsing) or from the browser itself (content -playback).

-

They all have a type property equal to "MEDIA_ERROR".

-

codes

-

A MediaError can have the following codes (code property):

-
    -
  • -

    "BUFFER_APPEND_ERROR": A media segment could not have been added to the -corresponding media buffer. This often happens with malformed segments.

    -
    • -
  • -

    "BUFFER_FULL_ERROR": The needed segment could not have been added -because the corresponding media buffer was full.

    -
    • -
  • -

    "BUFFER_TYPE_UNKNOWN": The type of buffer considered (e.g. “audio” / -“video” / “text”) has no media buffer implementation in your build.

    -
    • -
  • -

    "MANIFEST_INCOMPATIBLE_CODECS_ERROR": An -Adaptation (or track) has none of its -Representations (read quality) in a supported -codec.

    -
    • -
  • -

    "MANIFEST_PARSE_ERROR": Generic error to signal than the -Manifest could not be parsed.

    -
    • -
  • -

    "MANIFEST_UNSUPPORTED_ADAPTATION_TYPE": One of the -Adaptation has a type (e.g. “audio”, “text” or -“video” which is not managed by the RxPlayer).

    -
    • -
  • -

    "MEDIA_ERR_ABORTED": A crucial browser-side fetching operation was -aborted.

    -
    • -
  • -

    "MEDIA_ERR_BLOCKED_AUTOPLAY": The current browser has a policy which -forbids us to autoPlay the content. As a consequence, the rx-player stays -in a "LOADED" state. -This code is always a warning and it never causes playback interruption.

    -
    • -
  • -

    "MEDIA_ERR_PLAY_NOT_ALLOWED": A play call on our API (coming from you) -failed because the current browser does not allow it. -The content should still be in a paused state. -This is in almost any case due a browser policy which prevents a content to -play without any user interaction. -In those cases, we recommend to display a UI element on your page inviting -the final user to manually play the content.

    -
    • -
  • -

    "MEDIA_ERR_NOT_LOADED_METADATA": The current browser falsely announce -having loaded the content’s metadata. -In that case, we cannot switch to the LOADED state directly (we will -be blocked in either a LOADING or a RELOADING state) and you’re -encouraged to call play manually when you want to play the content. -This is a case only encountered in the Samsung browser (as found in -Android) when loading a content in “directfile” mode.

    -
    • -
  • -

    "MEDIA_ERR_DECODE": A pushed segment/media could not be decoded by the -browser. This happens most-of-all with malformed segments.

    -
    • -
  • -

    "MEDIA_ERR_NETWORK": A browser-side request failed.

    -
    • -
  • -

    "MEDIA_ERR_SRC_NOT_SUPPORTED": The media associated to the video element -is not valid.

    -
    • -
  • -

    "MEDIA_ERR_UNKNOWN": Media error impossible to characterize.

    -
    • -
  • -

    "MEDIA_KEYS_NOT_SUPPORTED": The current browser has no MediaKeys -implementation and the content is encrypted.

    -
    • -
  • -

    "MEDIA_SOURCE_NOT_SUPPORTED": No known MediaSource API is supported by -your browser and we need to create one.

    -
    • -
  • -

    "MEDIA_STARTING_TIME_NOT_FOUND": The provided or calculated starting -time was not found in the corresponding media.

    -
    • -
  • -

    "MEDIA_TIME_BEFORE_MANIFEST": The current time in the media is behind -what is currently declared in the Manifest. -This can lead to stalling indefinitely as the player won’t be able to -download new segments arround the current time.

    -
    • -
  • -

    "MEDIA_TIME_AFTER_MANIFEST": The current time in the media is after what -is currently declared in the Manifest. -This can lead to stalling indefinitely as the player won’t be able to -download new segments arround the current time.

    -
    • -
  • -

    "DISCONTINUITY_ENCOUNTERED": A discontinuity (i.e. a hole in the media -buffer) has been encontered and seeked over.

    -

    This is rarely a problem and may be encountered at a very start of a content -when the initial segment’s start is much later than expected.

    -
    • -
  • -

    "NO_PLAYABLE_REPRESENTATION": The currently chosen Adaptation does not -contain any playable Representation. This usually happen when every -Representation has been blacklisted due to encryption limitations.

    -
    • -
  • -

    "MANIFEST_UPDATE_ERROR": This error should never be emitted as it is -handled internally by the RxPlayer. Please open an issue if you encounter -it.

    -

    This error is triggered when an incoherent version of the Manifest was -received during a partial update. The RxPlayer should catch the error and -trigger a full update instead when that happens.

    -
    • -
  • -

    "MEDIA_TIME_NOT_FOUND": This error should never be emitted by the -RxPlayer. Please open an issue if you encounter it.

    -

    It is triggered when a time we initially thought to be in the bounds of the -Manifest actually does not link to any “Period” of the Manifest.

    -
    • -
-

-

-

ENCRYPTED_MEDIA_ERROR

-

Those errors are linked to the Encrypted Media Extensions. They concern various -DRM-related problems.

-

They all have a type property equal to "ENCRYPTED_MEDIA_ERROR".

-

codes

-

An EncryptedMediaError can have the following codes (code property):

-
    -
  • -

    "INCOMPATIBLE_KEYSYSTEMS": None of the provided key systems was -compatible with the current browser.

    -
    • -
  • -

    "INVALID_ENCRYPTED_EVENT": An encountered encrypted event was not -valid.

    -
    • -
  • -

    "INVALID_KEY_SYSTEM": One of the given key system was not accepted by -the RxPlayer.

    -
    • -
  • -

    "KEY_ERROR": The MediaKeySession emitted an error.

    -
    • -
  • -

    "KEY_GENERATE_REQUEST_ERROR": An error happened when calling the -generateRequest API to generate a challenge.

    -
    • -
  • -

    "KEY_LOAD_ERROR": An error was returned by the code fetching the -license.

    -
    • -
  • -

    "KEY_LOAD_TIMEOUT": The request for fetching the license had a duration -of more than 10 seconds.

    -
    • -
  • -

    "KEY_STATUS_CHANGE_ERROR": An error was detected when the -MediaKeySession emitted a keyStatuseschange event (e.g. the key -became "expired").

    -
    • -
  • -

    "KEY_UPDATE_ERROR": An error was detected after a message (like a -license was given to the CDM).

    -
    • -
  • -

    "LICENSE_SERVER_CERTIFICATE_ERROR": The server certificate of a -MediaKeys could not be set.

    -
    • -
  • -

    "MEDIA_IS_ENCRYPTED_ERROR": The media is encrypted and no key system -was given to the RxPlayer’s APIs.

    -
    • -
  • -

    "MULTIPLE_SESSIONS_SAME_INIT_DATA": This error should never be emitted -by the RxPlayer. Please open an issue if you encounter it.

    -

    It is emitted when the RxPlayer try to open multiple MediaKeySession for -the same initialization data (instead of using the exact same -MediaKeySession).

    -
    • -
-

-

-

OTHER_ERROR

-

Those errors are various other errors which does not belong to other types.

-

They all have a type property equal to "OTHER_ERROR".

-

codes

-

An OtherError can have the following codes (code property):

-
    -
  • -

    "PIPELINE_LOAD_ERROR": The Manifest or segment -request failed and the request has been done through a given callback (i.e. -not the RxPlayer’s XMLHttpRequest implementation).

    -
    • -
  • -

    "PIPELINE_PARSE_ERROR": The RxPlayer’s Manifest -or segment parsing logic failed. This is most likely due to a malformed -Manifest or segment.

    -
    • -
  • -

    "INTEGRITY_ERROR": An integrity-checking mechanism in the RxPlayer -detected that there was an error with some loaded data. Such mechanism can -be triggered for example when the checkMediaSegmentIntegrity -transportOptions is set to loadVideo.

    -
    • -
  • -

    "NONE": The error cannot be characterized.

    -
    • -

Exported Types

-

The RxPlayer being written in TypeScript, it has type definitions attached to -its source code that can be helpful if you develop an application in TypeScript -yourself.

-

-

“Using” types

-

Because we follow the usual way of adding definition files (as d.ts file -alongside our sources), those typings should be auto-exported when importing our -library in your favorite editor (as long as it is linked to a TSServer of some -sort).

-

-

Importing specific types

-

As some APIs can have pretty complicated arguments, you might also want to -import some of our internal type definitions into your code.

-

To simplify this process, we export some type definitions which can be imported -through the following line in your file:

-
import { SOME_TYPE } from "rx-player/types"
-
-

Here are the list of exported types, per category.

-

-

RxPlayer Constructor

-

The type IConstructorOptions corresponds to the interface that the -RxPlayer constructor accepts as an argument.

-

Example:

-
import RxPlayer from "rx-player";
-import { IConstructorOptions } from "rx-player/types";
-
-function generateConstructorOptions() : IConstructorOptions {
-  const videoElement = document.querySelector("video");
-  return {
-    stopAtEnd: false,
-    videoElement,
-  };
-}
-
-const options = generateConstructorOptions();
-const player = new RxPlayer(options);
-
-export default player;
-
-

Two constructor options have also their type definition exported, those are:

-
    -
  • -

    IAudioTrackPreference: which is the type of a single element in the -preferredAudioTracks array.

    -
    • -
  • -

    ITextTrackPreference: which is the type of a single element in the -preferredTextTracks array.

    -
    • -
-

-

loadVideo

-

The ILoadVideoOptions type corresponds to the argument to give to the -RxPlayer’s method loadVideo.

-

Example:

-
// the type(s) wanted
-import { ILoadVideoOptions } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object
-import config from "./config"; // define a global config
-
-function generateLoadVideoOptions(url : string) : ILoadVideoOptions {
-  return {
-    url,
-    transport: "dash",
-    autoPlay: true,
-  };
-}
-
-const loadVideoOpts = generateLoadVideoOptions(config.DEFAULT_URL);
-rxPlayer.loadVideo(loadVideoOpts);
-
-

Speaking of loadVideo, some subparts of ILoadVideoOptions are also -exported:

-
    -
  • -

    ITransportOptions: type for the transportOptions property -optionally given to loadVideo.

    -
    • -
  • -

    IKeySystemOption: type for an element of the keySystems array, -which is an optional property given to loadVideo.

    -

    To clarify, the keySystems property in a loadVideo call is an -optional array of one or multiple IKeySystemOption.

    -
    • -
  • -

    ISupplementaryTextTrackOption: type for an element of the -supplementaryTextTracks array, which is an optional property given to -loadVideo.

    -
    • -
  • -

    ISupplementaryImageTrackOption: type for an element of the -supplementaryImageTracks array, which is an optional property given to -loadVideo.

    -
    • -
  • -

    IDefaultAudioTrackOption: type for the defaultAudioTrack property -optionally given to loadVideo.

    -
    • -
  • -

    IDefaultTextTrackOption: type for the defaultAudioTrack property -optionally given to loadVideo.

    -
    • -
  • -

    INetworkConfigOption: type for the networkConfig property -optionally given to loadVideo.

    -
    • -
  • -

    IStartAtOption: type for the startAt property optionally given to -loadVideo.

    -
    • -
-

-

getAvailableAudioTracks method / availableAudioTracksChange event

-

The return type of the getAvailableAudioTracks method is an array of objects. -Each of this objects corresponds to the IAvailableAudioTrack interface.

-

Example:

-
// the type(s) wanted
-import { IAvailableAudioTrack } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object
-import config from "./config"; // define a global config
-
-function getAvailableAudioTracks() : IAvailableAudioTrack[] {
-  return rxPlayer.getAvailableAudioTracks();
-}
-
-

-

getAvailableTextTracks method / availabletextTracksChange event

-

The return type of the getAvailableTextTracks method is an array of objects. -Each of this objects corresponds to the IAvailableTextTrack interface.

-

Example:

-
// the type(s) wanted
-import { IAvailableTextTrack } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object
-import config from "./config"; // define a global config
-
-function getAvailableTextTracks() : IAvailableTextTrack[] {
-  return rxPlayer.getAvailableTextTracks();
-}
-
-

-

getAvailableVideoTracks method / availableVideoTracksChange event

-

The return type of the getAvailableVideoTracks method is an array of objects. -Each of this objects corresponds to the IAvailableVideoTrack interface.

-

Example:

-
// the type(s) wanted
-import { IAvailableVideoTrack } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object
-import config from "./config"; // define a global config
-
-function getAvailableVideoTracks() : IAvailableVideoTrack[] {
-  return rxPlayer.getAvailableVideoTracks();
-}
-
-

-

getAudioTrack method /audioTrackChange event

-

The IAudioTrack corresponds to both the type returned by the getAudioTrack -method and emitted as the payload of the audioTrackChange event.

-

Example:

-
// the type(s) wanted
-import { IAudioTrack } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object
-import config from "./config"; // define a global config
-
-rxPlayer.addEventListener("audioTrackChange", (track : IAudioTrack) => {
-  console.log("current track:", track);
-});
-
-function getCurrentlyDownloadedAudioTrack() : IAudioTrack {
-  return rxPlayer.getAudioTrack();
-}
-
-

-

getTextTrack method / textTrackChange event

-

The ITextTrack corresponds to both the type returned by the getTextTrack -method and emitted as the payload of the textTrackChange event.

-

Example:

-
// the type(s) wanted
-import { ITextTrack } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object

-rxPlayer.addEventListener("textTrackChange", (track : ITextTrack) => {
-  console.log("current track:", track);
-});
-
-function getCurrentlyDownloadedTextTrack() : ITextTrack {
-  return rxPlayer.getTextTrack();
-}
-
-

-

getVideoTrack method / videoTrackChange event

-

The IVideoTrack corresponds to both the type returned by the getVideoTrack -method and emitted as the payload of the videoTrackChange event.

-

Example:

-
// the type(s) wanted
-import { IVideoTrack } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";
-
-// hypothetical file exporting a configuration object
-import config from "./config"; // define a global config
-
-rxPlayer.addEventListener("videoTrackChange", (track : IVideoTrack) => {
-  console.log("current track:", track);
-});
-
-function getCurrentlyDownloadedVideoTrack() : IVideoTrack {
-  return rxPlayer.getVideoTrack();
-}
-
-

-

streamEvent / streamEventSkip events

-

The type IStreamEvent corresponds to the payload of either a streamEvent or -a streamEventSkip event.

-

The type IStreamEventData is the type of its data property.

-

Example:

-
// the type(s) wanted
-import { IStreamEvent, IStreamEventData } from "rx-player/types";
-
-// hypothetical file exporting an RxPlayer instance
-import rxPlayer from "./player";

-function processEventData(eventData : IStreamEventData) {
-  if (eventData.type === "dash-event-stream") {
-    console.log("DASH EventStream's event received!");
-  }
-}
-
-rxPlayer.addEventListener("streamEvent", (evt : IStreamEvent) {
-  processEventData(evt.data);
-});

Images

-

Overview

-

The RxPlayer defines its own image playlist format, the bif format.

-

This format allows to transmit playlist of thumbnails for linear (live) and -non-linear (VOD) contents. The usecase is mostly to allow an improved “seeking” -experience.

-

It is understood and parsed by the player, which offers API to easily integrate -those features in an application.

-

-

-

Format specification

-

This documentation is not yet finished. It will be very soon.

-

-

-

Using bif for DASH and smooth contents

-

This documentation is not yet finished. It will be very soon.

-

-

-

APIs

-

Images can be retreived through two APIs for now:

-
    -
  • -

    getImageTrackData, which returns directly an array of objects describing -the images in the playlist.

    -
    • -
  • -

    the imageTrackUpdate event, which emits each time the image playlist is -updated with the complete playlist as an array of objects in its data -property.

    -
    • -
-

-

-

Structure

-

In both of those cases you receive an array of Objects, each defining a single -image.

-

An image object has the following property:

-
    -
  • -

    data (Uint8Array): the raw data for the image object. You can -display the corresponding image on your page thanks to the browser -window.URL.createObjectURL API.

    -
    • -
  • -

    ts (Number): the position (relatively to the player’s -getPosition API) the image should be displayed at, in milliseconds.

    -
    • -
  • -

    duration (Number): the duration, in s, until a new image can be -considered.

    -
    • -
-

This array should be ordered by position.

-

-

-

Example

-

Here is an example of setting the image corresponding to the current position, -considering a player instance player and an image element with the id -current-image:

-
const position = player.getPosition();
-const imagePlaylist = player.getImageTrackData();
-
-const currentImage = imagePlaylist.find(p => (p.ts / 1000) > position);
-
-if (currentImage) {
-  const blob = new Blob([currentImage], {type: "image/jpeg"});
-  const url = URL.createObjectURL(blob);
-  document.getElementById("current-image").src = url;
-}

RxPlayer API

-

-

-

Overview

-

The RxPlayer has a complete API allowing you to:

-
    -
  • load and stop contents containing video and/or audio media data
    • -
  • control playback (play, pause, seek, etc.) when a content is loaded.
    • -
  • get multiple information on the current content and on the player’s state.
    • -
  • choose a specific audio language, subtitles track video track
    • -
  • force a given bitrate
    • -
  • update the wanted buffer length to reach
    • -
  • and more
    • -
-

The following pages define the entire API.

-

⚠️ Only variables and methods defined here are considered as part of the -API. Any other property or method you might find in any other way are not -considered as part of the API and can thus change without notice.

-

Note: As some terms used here might be too foreign or slightly different than -the one you’re used to, we also wrote a list of terms and definitions used by -the RxPlayer here.

-

-

-

Instantiation

-

Instantiating a new RxPlayer is necessary before being able to load a content. -Doing so is straightforward:

-
import RxPlayer from "rx-player";
-const player = new RxPlayer(options);
-
-

The options are all… optional. They are all defined in the Player Options -page.

-

-

-

Basic methods

-

In this chapter, we will go through the basic methods you will need to use when -playing a content through the RxPlayer.

-

-

-

loadVideo

-

–

-

syntax: player.loadVideo(options)

-

arguments:

-
    -
  • options (Object): Content you want to load and associated options.
    • -
-

–

-

Loads the content described in the argument.

-

This is the central method to use when you want to play a new content. -The options possible as arguments are all defined in this -page.

-

Despite its name, this method can also load audio-only content.

-

Example

-
player.loadVideo({
-  url: "http://vm2.dashif.org/livesim-dev/segtimeline_1/testpic_6s/Manifest.mpd",
-  transport: "dash",
-  autoPlay: true,
-});
-
-

-

-

reload

-

–

-

syntax: player.reload() / player.reload(options)

-

arguments:

-
    -
  • options (Object | undefined): Optional requirements, e.g. at which -position the player should reload.
    • -
-

–

-

Re-load the last loaded content as fast as possible.

-

This API can be called at any time after a content has been loaded (the LOADED -state has been reached), even if the player has been stopped since and even if -it was due to a fatal error.

-

The user may need to call this API in several cases. For example, it may be used -in case of an error that will not reproduce or inversely when the error is -consistent at a certain playback time (e.g. due to a specific chunk defect).

-

The options argument is an object containing :

-
    -
  • reloadAt (Object | undefined): The object contain directives about -the starting playback position : -
      -
    • relative (string | undefined) : start playback relatively from the -last playback position (last played position before entering into STOPPED or -ENDED state).
      • -
    • position (string|undefined) : absolute position at which we should -start playback
      • -
    -
    • -
-

If no reload position is defined, start playback at the last playback position.

-

Note that despite this method’s name, the player will not go through the -RELOADING state while reloading the content but through the regular LOADING -state - as if loadVideo was called on that same content again.

-

Example

-
player.addEventListener("error", (error) => {
-  if (error.code === "BUFFER_APPEND_ERROR") {
-    // Try to reload after the last playback position, in case of defectuous
-    // media content at current time.
-    player.reload({ reloadAt: { relative: +5 }});
-  } else {
-    // Try to reload at the last playback position
-    player.reload();
-  }
-});
-
-

-

-

getPlayerState

-

–

-

syntax: const state = player.getPlayerState()

-

return value: string

-

–

-

Returns the “state” the player is currently in. -Can be either one of those strings:

-
    -
  • -

    "STOPPED": The player is idle. No content is loading nor is loaded.

    -
    • -
  • -

    "LOADING": The player is loading a new content. -Most APIs related to the current content are not yet available while the -content is loading.

    -
    • -
  • -

    "LOADED": The player has loaded the new content, it is now ready to -play. -From this point onward you can use APIs interacting with the current content -such as seekTo or setAudioTrack.

    -
    • -
  • -

    "PLAYING": The player is currently playing the content.

    -
    • -
  • -

    "PAUSED": The player has paused.

    -
    • -
  • -

    "ENDED": The player has reached the end of the current content.

    -
    • -
  • -

    "BUFFERING": the player has reached the end of the buffer and is waiting -for data to be appended.

    -
    • -
  • -

    "SEEKING": The player has reached the end of the buffer because a seek -has been performed, new segments are being loaded.

    -
    • -
  • -

    "RELOADING": The player needs to reload its current (for example, when -switching the current video track). -While this state is active, most API related to the currently playing -content are not available. This state should be treated like the LOADING -state.

    -
    • -
-

As it is a central part of our API and can be difficult concept to understand, -we have a special page of documentation on player states.

-

Example

-
switch (player.getPlayerState()) {
-  case "STOPPED":
-    console.log("No content is/will be playing");
-    break;
-  case "LOADING":
-    console.log("A new content is currently loading");
-    break;
-  case "LOADED":
-    console.log("The new content is loaded and ready to be played");
-    break;
-  case "PLAYING":
-    console.log("The content is currently playing");
-    break;
-  case "PAUSED":
-    console.log("The content is currently paused");
-    break;
-  case "BUFFERING":
-    console.log("The content is buffering new data");
-    break;
-  case "SEEKING":
-    console.log("The content is still seeking, waiting for new data");
-    break;
-  case "ENDED":
-    console.log("The content has reached the end.");
-    break;
-  case "RELOADING":
-    console.log("The content is currently reloading");
-    break;
-  default:
-    console.log("This is impossible (issue material!).")
-    break;
-}
-
-

-

-

addEventListener

-

–

-

syntax: player.addEventListener(event, callback)

-

arguments:

-
    -
  • -

    event (string): The event name.

    -
    • -
  • -

    callback (Function): The callback for the event. -The same callback may be used again when calling removeEventListener.

    -
    • -
-

–

-

Add an event listener to trigger a callback as it happens. The callback will -have the event payload as a single argument.

-

The RxPlayer API is heavily event-based. As an example: to know when a content -is loaded, the most straightforward way is to add an event listener for the -"playerStateChange" event. This can be done only through this method.

-

To have the complete list of player events, consult the Player events -page.

-

Example

-
player.addEventListener("error", function(err) {
-  console.log(`The player crashed: ${err.message}`);
-});
-
-

-

-

removeEventListener

-

–

-

syntax: player.removeEventListener(event) / -player.removeEventListener(event, callback)

-

arguments:

-
    -
  • -

    event (string): The event name.

    -
    • -
  • -

    callback (optional) (Function): The callback given when calling the -corresponding addEventListener API.

    -
    • -
-

–

-

Remove an event listener. -That is, remove a callback previously registered with addEventListener from -being triggered on the corresponding event. This also free-up the corresponding -ressources.

-

The callback given is optional: if not given, every registered callback to -that event will be removed.

-

Example

-
player.removeEventListener("playerStateChange", listenerCallback);
-
-

-

-

play

-

–

-

syntax: player.play()

-

return value: Promise.<void>

-

–

-

Play/resume the current loaded video. Equivalent to a video element’s play -method.

-

You might want to call that method either to start playing (when the content is -in the "LOADED" state and auto-play has not been enabled in the last -loadVideo call) or to resume when the content has been paused.

-

The returned Promise informs you on the result:

-
    -
  • -

    if playback succeeds, the Promise is fulfilled

    -
    • -
  • -

    if playback fails, the Promise is rejected along with an error message -explaining the failure - coming directly from the browser.

    -

    Such failure can for example be due to your browser’s policy, which may -forbid to call play on a media element without any user interaction. -Please note that in that case, you will also receive a -warning event containing a MEDIA_ERROR with the code: -MEDIA_ERR_PLAY_NOT_ALLOWED.

    -
    • -
-

Note: On browsers which do not support Promises natively (such as Internet -Explorer 11), a JavaScript implementation is provided instead. This -implementation has the exact same implementation than ES2015 -Promises.

-

You might want for a content to be loaded before being able to play (the -current state has to be different than LOADING, RELOADING or STOPPED).

-

Example

-
const resumeContent = () => {
-  player.play();
-};
-
-

-

-

pause

-

–

-

syntax: player.pause()

-

–

-

Pause the current loaded video. Equivalent to a video element’s pause method.

-

Note that a content can be paused even if its current state is BUFFERING or -SEEKING.

-

You might want for a content to be loaded before being able to pause (the -current state has to be different than LOADING, RELOADING or STOPPED).

-

Example

-
const pauseContent = () => {
-  player.pause();
-};
-
-

-

-

stop

-

–

-

syntax: player.stop()

-

–

-

Stop playback of the current content if one.

-

This will totaly un-load the current content. -To re-start playing the same content, you can either call the reload method -or just call loadVideo again.

-

Example

-
const stopVideo = () => {
-  player.stop();
-};
-
-

-

-

getPosition

-

–

-

syntax: const position = player.getPosition()

-

return value: Number

-

–

-

Returns the current media element’s playing position, in seconds.

-

For live contents, the returned position will not be re-scaled to correspond to -a live timestamp. If you want that behavior, you can call getWallClockTime -instead.

-

This is the only difference between the two. Generally, you can follow the -following rule:

-
    -
  • -

    if you want to use that current position to use it with the other APIs -(like seekTo, getMinimumPosition, getMaximumPosition -etc.) use getPosition - as this is the real position in the media.

    -
    • -
  • -

    if you want to display the current position to the viewer/listener, use -getWallClockTime instead - as it will be set in the proper scale for -live contents to display the right live time.

    -
    • -
-

Example

-
const pos = player.getPosition();
-console.log(`The video element's current position is: ${pos} second(s)`);
-
-

-

-

getWallClockTime

-

–

-

syntax: const wallClockTime = player.getWallClockTime()

-

return value: Number

-

–

-

Returns the current “wall-clock” playing position in seconds.

-

That is:

-
    -
  • -

    for live contents, this is the current position scaled to correspond to a -live timestamp, in seconds.

    -
    • -
  • -

    for non-live contents, returns the position from the absolute beginning time -of the content, also in seconds. In the absolute majority of cases this will -be equal to the value returned by getPosition.

    -
    • -
-

Use this method to display the current position to the user.

-

Example

-
const wallClockTime = player.getWallClockTime();
-const nowInSeconds = Date.now() / 1000;
-const delta = nowInSeconds - wallClockTime;
-
-if (delta < 5) { // (5 seconds of margin)
-  console.log("You're playing live");
-} else {
-  console.log(`You're playing ${delta} seconds behind the live content`);
-}
-
-

-

-

seekTo

-

–

-

syntax: player.seekTo(position)

-

arguments:

-
    -
  • position (Object|Number): The position you want to seek to.
    • -
-

__

-

Seek in the current content (i.e. change the current position).

-

The argument can be an object with a single Number property, either:

-
    -
  • -

    relative: seek relatively to the current position

    -
    • -
  • -

    position: seek to the given absolute position (equivalent to -player.getVideoElement().currentTime = newPosition)

    -
    • -
  • -

    wallClockTime: seek to the given wallClock position, as returned by -getWallClockTime.

    -
    • -
-

The argument can also just be a Number property, which will have the same -effect than the position property (absolute position).

-

Seeking should only be done when a content is loaded (i.e. the player isn’t -in the STOPPED, LOADING or RELOADING state).

-

The seek operation will start as soon as possible, in almost every cases -directly after this method is called.

-

You will know when the seek is being performed and has been performed -respectively by listening to the seeking and seeked player events (see the -player events page). While seeking, the RxPlayer might -also switch to the SEEKING state.

-

Examples

-
// seeking to 54 seconds from the start of the content
-player.seekTo({ position: 54 });
-
-// equivalent to just:
-player.seekTo(54);
-
-// seeking 5 seconds after the current position
-player.seekTo({ relative: 5 });
-
-// seeking 5 seconds before the current position
-player.seekTo({ relative: -5 });
-
-// seeking to live content
-player.seekTo({ wallClockTime: Date.now() / 1000 });
-
-

-

-

getMinimumPosition

-

–

-

syntax: const minimumPosition = player.getMinimumPosition()

-

return value: Number|null

-

–

-

Returns the minimum seekable player position. -Returns null if no content is loaded.

-

This is useful for live contents, where the earliest time at which it is -possible to seek usually evolves over time. -This method allows to know the earliest possible time a seek can be performed -at any point in time.

-

As the given position is the absolute minimum position, you might add a security -margin (like a few seconds) when seeking to this position in a live content. -Not doing so could led to the player being behind the minimum position after -some time (e.g. because of buffering or decoding issues), and thus unable to -continue playing.

-

You will be alerted if the player’s position fell behind the minimum possible -position by receiving a warning event (see the player events -page) with an error having a MEDIA_TIME_BEFORE_MANIFEST -code property (see the player errors page). -Note that you can also have those warnings without any seek operation, e.g. due -to buffering for too long.

-

For VoD contents, as the minimum position normally doesn’t change, seeking at -the minimum position should not cause any issue.

-

Example

-
// Seeking close to the minimum position (with a 5 seconds security margin)
-player.seekTo({ position: player.getMinimumPosition() + 5 });
-
-

-

-

getMaximumPosition

-

–

-

syntax: const maximumPosition = player.getMaximumPosition()

-

return value: Number|null

-

–

-

Returns the maximum seekable player position. -Returns null if no content is loaded.

-

This is useful for live contents, where this position might be updated -continously as new content is generated. -This method allows thus to seek directly at the live edge of the content.

-

Please bear in mind that seeking exactly at the maximum position is rarely a -good idea:

-
    -
  • for VoD contents, the playback will end
    • -
  • for live contents, the player will then need to wait until it can build -enough buffer.
    • -
-

As such, we advise to remove a few seconds from that position when seeking.

-

Example

-
// seeking 5 seconds before the end (or the live edge for live contents)
-player.seekTo({
-  position: player.getMaximumPosition() - 5
-});
-
-

-

-

getVideoDuration

-

–

-

syntax: const duration = player.getVideoDuration()

-

return value: Number

-

–

-

Returns the duration of the current content as taken from the media element.

-

⚠️ This duration is in fact the maximum position possible for the -content. As such, for contents not starting at 0, this value will not be equal -to the difference between the maximum and minimum possible position, as would -normally be expected from a property named “duration”.

-

Example

-
const pos = player.getPosition();
-const dur = player.getVideoDuration();
-
-console.log(`current position: ${pos} / ${dur}`);
-
-

-

-

getError

-

–

-

syntax: const currentError = player.getError()

-

return value: Error|null

-

–

-

Returns the current “fatal error” if one happenned for the last loaded content. -Returns null otherwise.

-

A “fatal error” is an error which led the current loading/loaded content to -completely stop. -Such errors are usually also sent through the "error" event when they happen.

-

See the Player Error documentation for more information.

-

Example

-
const error = player.getError();
-
-if (!error) {
-  console.log("The player did not crash");
-} else if (error.code === "PIPELINE_LOAD_ERROR") {
-  console.error("The player crashed due to a failing request");
-} else {
-  console.error(`The player crashed: ${error.code}`);
-}
-
-

-

-

getVideoElement

-

–

-

syntax: const elt = player.getVideoElement()

-

return value: HTMLMediaElement

-

–

-

Returns the media element used by the RxPlayer.

-

You’re not encouraged to use its APIs as they can enter in conflict with the -RxPlayer’s API.

-

Despite its name, this method can also return an audio element if the RxPlayer -was instantiated with one.

-

Example

-
const videoElement = player.getVideoElement();
-videoElement.className = "my-video-element";
-
-

-

-

dispose

-

–

-

syntax: player.dispose()

-

–

-

Free the ressources used by the player.

-

You can call this method if you know you won’t need the RxPlayer anymore.

-

⚠️ The player won’t work correctly after calling this method.

-

-

-

Speed control

-

The following methods allows to update the current speed of playback (also -called the “playback rate”).

-

-

-

setPlaybackRate

-

–

-

syntax: player.setPlaybackRate(speed)

-

arguments:

-
    -
  • speed (Number): The speed / playback rate you want to set.
    • -
-

–

-

Updates the current playback rate, i.e. the speed at which contents are played.

-

As its name hints at, the value indicates the rate at which contents play:

-
    -
  • -

    Setting it to 2 allows to play at a speed multiplied by 2 relatively to -regular playback.

    -
    • -
  • -

    Setting that value to 1 reset the playback rate to its “normal” rythm.

    -
    • -

    Setting it to 0.5 allows to play at half the speed relatively to regular -playback.

    -
    • -
  • -

    etc.

    -
    • -
-

This method can be called at any time, even when no content is loaded and is -persisted from content to content.

-

You can set it to 1 to reset its value to the “regular” default.

-

Example

-
// plays three times faster than normal
-player.setPlaybackRate(3);
-
-

-

-

getPlaybackRate

-

–

-

syntax: const rate = player.getPlaybackRate()

-

return value: Number

-

–

-

Returns the current playback rate. 1 for normal playback, 2 when -playing at double the speed, etc.

-

Example

-
const currentPlaybackRate = player.getPlaybackRate();
-console.log(`Playing at a x${currentPlaybackRate}} speed`);
-
-

-

-

Volume control

-

Those methods allows to have control over the current audio volume of playing -contents.

-

-

-

setVolume

-

–

-

syntax: player.setVolume(volume)

-

arguments:

-
    -
  • volume (Number): Volume from 0 to 1.
    • -
-

–

-

Set the current volume, from 0 (no sound) to 1 (the maximum sound level).

-

Note that the volume set here is persisted even when loading another content. -As such, this method can also be called when no content is currently playing.

-

Example

-
// set the full volume
-player.setVolume(1);
-
-

-

-

getVolume

-

–

-

syntax: const volume = player.getVolume()

-

return value: Number

-

–

-

Current volume of the player, from 0 (no sound) to 1 (maximum sound). -0 if muted through the mute API.

-

As the volume is not dependent on a single content (it is persistent), this -method can also be called when no content is playing.

-

Example

-
const volume = player.getVolume();
-
-if (volume === 1) {
-  console.log("You're playing at maximum volume");
-} else if (volume === 0) {
-  console.log("You're playing at no volume");
-} else if (volume > 0.5) {
-  console.log("You're playing at a high volume");
-} else {
-  console.log("You're playing at a low volume");
-}
-
-

-

-

mute

-

–

-

syntax: player.mute()

-

–

-

Mute the volume.

-

Basically set the volume to 0 while keeping in memory the previous volume to -reset it at the next unMute call.

-

As the volume is not dependent on a single content (it is persistent), this -method can also be called when no content is playing.

-

Example

-
// mute the current volume
-player.mute();
-
-

-

-

unMute

-

–

-

syntax: player.unMute()

-

–

-

When muted, restore the volume to the one previous to the last mute call.

-

When the volume is already superior to 0, this call won’t do anything.

-

As the volume is not dependent on a single content (it is persistent), this -method can also be called when no content is playing.

-

Example

-
// mute the current volume
-player.mute();
-
-// unmute and restore the previous volume
-player.unMute();
-
-

-

-

isMute

-

–

-

syntax: const isMute = player.isMute()

-

return value: Boolean

-

–

-

Returns true if the volume is set to 0.

-

Example

-
if (player.isMute()) {
-  console.log("The content plays with no sound.");
-}

setAudioTrack

-

–

-

syntax: player.setAudioTrack(audioTrackId)

-

arguments:

-
    -
  • audioTrackId (string|Number): The id of the track you want to set
    • -
-

–

-

Change the current audio track.

-

The argument to this method is the wanted track’s id property. This id can -for example be obtained on the corresponding track object returned by the -getAvailableAudioTracks method.

-

–

-

Note for multi-Period contents:

-

This method will only have an effect on the Period that is -currently playing. -If you want to update the track for other Periods as well, you might want to -either:

-
    -
  • update the current audio track once a "periodChange" event has been -received.
    • -
  • update first the preferred audio tracks through the -setPreferredAudioTracks method.
    • -
-

–

-

⚠️ If used on Safari, in DirectFile mode, the track change may change -the track on other track type (e.g. changing video track may change subtitle -track too). -This has two potential reasons :

-
    -
  • The HLS defines variants, groups of tracks that may be read together
    • -
  • Safari may decide to enable a track for accessibility or user language -convenience (e.g. Safari may switch subtitle to your OS language if you pick -another audio language) -You can know if another track has changed by listening to the corresponding -events that the tracks have changed.

-

syntax: player.setTextTrack(textTrackId)

-

arguments:

-
    -
  • textTrackId (string|Number): The id of the track you want to set
    • -
-

–

-

Change the current text (subtitles) track.

-

The argument to this method is the wanted track’s id property. This id can -for example be obtained on the corresponding track object returned by the -getAvailableTextTracks method.

-

–

-

Note for multi-Period contents:

-

This method will only have an effect on the Period that is -currently playing.

-

If you want to disable the text track for other Periods as well, you might want -to call setPreferredVideoTracks instead. With -this method, you can globally apply a null text track preference - which means -that you would prefer having no text track - by setting its second argument to -true.

-

More information can be found on that API’s documentation.

-

–

-

Change the current video track.

-

The argument to this method is the wanted track’s id property. This id can -for example be obtained on the corresponding track object returned by the -getAvailableVideoTracks method.

-

Setting a new video track when a previous one was already playing can lead the -rx-player to “reload” this content.

-

During this period of time:

-
    -
  • the player will have the state RELOADING
    • -
  • Multiple APIs linked to the current content might not work. -Most notably: -

-

⚠️ This option may have no effect in DirectFile mode -(see loadVideo options). -The directfile mode is a special case here because when in it, the RxPlayer -depends for track selection on the corresponding HTML -standard as implemented by -the different browsers. -Though this standard says nothing about not being able to disable the video -track (or to stay more in line with their terms: to not select any video track), -no browser implementation actually seem to be able to do it, even when the -corresponding browser APIs show that no video track is currently selected. -This might be a bug on their parts.

-

Due to this fact, we do not recommend using this API in directfile mode for -now. You might even receive a reassuring videoTrackChange event (with a null -payload) while the video track is still actually active.

-

setPreferredAudioTracks

-

–

-

syntax: player.setPreferredAudioTracks(preferences) / -player.setPreferredAudioTracks(preferences, shouldApply)

-

arguments:

-
    -
  • -

    preferences (Array.<Object>): wanted audio track configurations by -order of preference.

    -
    • -
  • -

    shouldApply (Boolean | undefined): Whether this should be applied to the -content being played.

    -
    • -
-

–

-

Allows the RxPlayer to choose an initial audio track, based on language -preferences, codec preferences or both.

-

This method can be called at any time - even when no content is loaded, and will -apply to every future loaded content in the current RxPlayer instance.

-

–

-

The first argument should be set as an array of objects, each object describing -constraints an audio track should respect.

-

Here is all the possible constraints you can set in any one of those objects -(note that all properties are optional here, only those set will have an effect -on which tracks will be filtered):

-
-  codec: { // {Object|undefined} Constraints about the codec wanted.
-           // if not set or set to `undefined` we won't filter based on codecs.
-
-    test: /ec-3/, // {RegExp} RegExp validating the type of codec you want.
-
-    all: true, // {Boolean} Whether all the profiles (i.e. Representation) in a
-               // track should be checked against the RegExp given in `test`.
-               // If `true`, we will only choose a track if EVERY profiles for
-               // it have a codec information that is validated by that RegExp.

When encountering a new content or a new choice of tracks in a given content, -the RxPlayer will look at each object in that array. -If the first object in it defines constaints that cannot be respected under the -currently available audio tracks, the RxPlayer will consider the second object -in the array and so on.

-

As such, this array should be sorted by order of preference: from the most -wanted constraints to the least.

-

–

-

The second argument to that function is an optional boolean which - when set -to true - will apply that preference to the content and Period that have -already been playing.

-

By setting it to true, you might thus change the currently-active track and -the active track of Periods (in DASH) or sub-contents (in MetaPlaylist) that -have already been played in the current content.

-

By setting it to false, undefined or not setting it, those preferences will -only be applied each time a new Period or sub-content is loaded by the -RxPlayer.

-

Simply put, if you don’t set the second argument to true those preferences -won’t be applied to:

-
    -
  • -

    the content being currently played. -Here, the current audio preference will stay in place.

    -
    • -
  • -

    the Periods or sub-contents which have already been loaded for the current -content. -Those will keep the audio track chosen at the last time they were loaded.

    -
    • -
-

If you want the preferences to also be applied to those, you can set the second -argument to true.

-

Examples

-

Let’s imagine that you prefer to have french or italian over all other audio -languages. If not found, you want to fallback to english:

-
player.setPreferredAudioTracks([
-  { language: "fra", audioDescription: false },
-  { language: "ita", audioDescription: false },
-  { language: "eng", audioDescription: false }
-])
-
-

Now let’s imagine that you want to have in priority a track that contain at -least one profile in Dolby Digital Plus (ec-3 codec) without caring about the -language:

-
player.setPreferredAudioTracks([ { codec: { all: false, test: /ec-3/ } ]);
-
-

At last, let’s combine both examples by preferring french over itialian, italian -over english while preferring it to be in Dolby Digital Plus:

-

-player.setPreferredAudioTracks([
-  {
-    language: "fra",
-    audioDescription: false,
-    codec: { all: false, test: /ec-3/ }
-  },
-
-  // We still prefer non-DD+ french over DD+ italian
-  { language: "fra", audioDescription: false },
-
-  {
-    language: "ita",
-    audioDescription: false,
-    codec: { all: false, test: /ec-3/ }
-  },
-  { language: "ita", audioDescription: false },
-
-  {
-    language: "eng",
-    audioDescription: false,
-    codec: { all: false, test: /ec-3/ }
-  },
-  { language: "eng", audioDescription: false }
-]);

-

getPreferredAudioTracks

-

–

-

syntax: const preferences = player.getPreferredAudioTracks()

-

return value: Array.<Object>

-

–

-

Returns the current list of preferred audio tracks - by order of preference.

-

This returns the data in the same format that it was given to either the -preferredAudioTracks constructor option or the last setPreferredAudioTracks -if it was called.

-

It will return an empty Array if none of those two APIs were used until now.

-

-

-

setPreferredTextTracks

-

–

-

syntax: player.setPreferredTextTracks(preferences) / -player.setPreferredTextTracks(preferences, shouldApply)

-

arguments:

-
    -
  • -

    preferences (Array.<Object>): wanted text track configurations by -order of preference.

    -
    • -
  • -

    shouldApply (Boolean | undefined): Whether this should be applied to the -content being played.

    -
    • -
-

–

-

Allows the RxPlayer to choose an initial text track, based on language -and accessibility preferences.

-

This method can be called at any time - even when no content is loaded, and will -apply to every future loaded content in the current RxPlayer instance.

-

–

-

The first argument should be set as an array of objects, each object describing -constraints a text track should respect.

-

Here is all the properties that should be set in a single object of that array.

-
{
-  language: "fra", // {string} The wanted language
-                   // (ISO 639-1, ISO 639-2 or ISO 639-3 language code)
-  closedCaption: false // {Boolean} Whether the text track should be a closed
-                       // caption for the hard of hearing
-}
-
-

When encountering a new content or a new choice of tracks in a given content, -the RxPlayer will look at each object in that array. -If the first object in it defines constaints that cannot be respected under the -currently available text tracks, the RxPlayer will consider the second object -in the array and so on.

-

As such, this array should be sorted by order of preference: from the most -wanted constraints to the least.

-

You can set null instead of an object to mean that you want no subtitles. -When reaching that point of the array, the RxPlayer will just disable the -current text track.

-

As such, if you never want any subtitles, you can just set this argument to -[null] (an array with only the value null at the first position).

-

–

-

The second argument to that function is an optional boolean which - when set -to true - will apply that preference to the content and Period that have -already been playing.

-

By setting it to true, you might thus change the currently-active text track -and the active text track of Periods (in DASH) or sub-contents (in -MetaPlaylist) that have already been played in the current content.

-

By setting it to false, undefined or not setting it, those preferences will -only be applied each time a new Period or sub-content is loaded by the -RxPlayer.

-

Simply put, if you don’t set the second argument to true those preferences -won’t be applied to:

-
    -
  • -

    the content being currently played. -Here, the current text track preference will stay in place.

    -
    • -
  • -

    the Periods or sub-contents which have already been loaded for the current -content. -Those will keep the text track chosen at the last time they were loaded.

    -
    • -
-

If you want the preferences to also be applied to those, you can set the second -argument to true.

-

Example

-

Let’s imagine that you prefer to have french or italian subtitles.If not found, -you want no subtitles at all.

-

You will thus call setPreferredTextTracks that way.

-
player.setPreferredTextTracks([
-  { language: "fra", closedCaption: false },
-  { language: "ita", closedCaption: false },
-  null
-]);
-
-

This won’t apply on the currently loaded content(s), if you also want that, you -can add true as a second argument:

-
player.setPreferredTextTracks([
-  { language: "fra", closedCaption: false },
-  { language: "ita", closedCaption: false },
-  null
-], true);
-

-

–

-

This returns the data in the same format that it was given to either the -preferredTextTracks constructor option or the last setPreferredTextTracks if -it was called:

-
{
-  language: "fra", // {string} The wanted language
-                   // (ISO 639-1, ISO 639-2 or ISO 639-3 language code)

-

setPreferredVideoTracks

-

–

-

syntax: player.setPreferredVideoTracks(preferences) / -player.setPreferredVideoTracks(preferences, shouldApply)

-

arguments:

-
    -
  • -

    preferences (Array.<Object>): wanted video track configurations by -order of preference.

    -
    • -
  • -

    shouldApply (Boolean | undefined): Whether this should be applied to the -content being played.

    -
    • -
-

–

-

Allows the RxPlayer to choose an initial video track, based on codec -preferences, accessibility preferences or both.

-

This method can be called at any time - even when no content is loaded, and will -apply to every future loaded content in the current RxPlayer instance.

-

–

-

The first argument should be set as an array of objects, each object describing -constraints a video track should respect.

-

Here is all the possible constraints you can set in any one of those objects -(note that all properties are optional here, only those set will have an effect -on which tracks will be filtered):

-
{
-  codec: { // {Object|undefined} Constraints about the codec wanted.
-           // if not set or set to `undefined` we won't filter based on codecs.
-
-    test: /hvc/, // {RegExp} RegExp validating the type of codec you want.
-
-    all: true, // {Boolean} Whether all the profiles (i.e. Representation) in a
-               // track should be checked against the RegExp given in `test`.
-               // If `true`, we will only choose a track if EVERY profiles for
-               // it have a codec information that is validated by that RegExp.
-               // If `false`, we will choose a track if we know that at least
-               // A SINGLE profile from it has codec information validated by
-               // that RegExp.
-  }
-  signInterpreted: true, // {Boolean|undefined} If set to `true`, only tracks
-                         // which are known to contains a sign language
-                         // interpretation will be considered.
-                         // If set to `false`, only tracks which are known
-                         // to not contain it will be considered.
-                         // if not set or set to `undefined` we won't filter
-                         // based on that status.
-}
-
-

If the first defined object in that array - defining the first set of -constraints - cannot be respected under the currently available video tracks, -the RxPlayer will check with the second object instead and so on.

-

As such, this array should be sorted by order of preference: from the most -wanted constraints to the least.

-

When the next encountered constraint is set to null, the player will simply -disable the video track. If you want to disable the video track by default, -you can just set null as the first element of this array (e.g. like [null]).

-

–

-

The second argument to that function is an optional boolean which - when set -to true - will apply that preference to the content and Period that have -already been playing.

-

By setting it to true, you might thus change the currently-active track and -the active track of Periods (in DASH) or sub-contents (in MetaPlaylist) that -have already been played in the current content.

-

By setting it to false, undefined or not setting it, those preferences will -only be applied each time a new Period (or sub-content) is loaded by the -RxPlayer.

-

Simply put, if you don’t set the second argument to true those preferences -won’t be applied to:

-
    -
  • -

    the content being currently played. -Here, the current video preference will stay in place.

    -
    • -
  • -

    the Periods or sub-contents which have already been loaded for the current -content. -Those will keep the video track chosen at the last time they were loaded.

    -
    • -
-

If you want the preferences to also be applied to those, you can set the second -argument to true.

-

Examples

-

Let’s imagine that you prefer to have a track which contains only H265 -profiles. You can do:

-
player.setPreferredVideoTracks([ { codec: { all: false, test: /^hvc/ } } ]);
-
-

With that same constraint, let’s no consider that the current user prefer in any -case to have a sign language interpretation on screen:

-
player.setPreferredVideoTracks([
-  // first let's consider the best case: H265 + sign language interpretation
-  {
-    codec: { all: false, test: /^hvc/ }
-    signInterpreted: true,
-  },
-
-  // If not available, we still prefer a sign interpreted track without H265
-  { signInterpreted: true },
-
-  // If not available either, we would prefer an H265 content
-  { codec: { all: false, test: /^hvc/ } },
-
-  // Note: If this is also available, we will here still have a video track
-  // but which do not respect any of the constraints set here.
-]);
-would thus prefer the video to contain a sign language interpretation.
-We could set both the previous and that new constraint that way:
-
----
-
-For a totally different example, let's imagine you want to play without any
-video track enabled (e.g. to start in an audio-only mode). To do that, you can
-simply do:
-```js
-player.setPreferredVideoTracks([null], true);
-
-
-

Bitrate selection

-

The following methods allows to choose a given bitrate for audio or video -content. It can also enable or disable an adaptive bitrate logic or influence -it.

-

-

-

getAvailableVideoBitrates

-

–

-

syntax: const bitrates = player.getAvailableVideoBitrates()

-

return value: Array.<Number>

-

–

-

The different bitrates available for the current video track in bits per -seconds.

-

–

-

Note for multi-Period contents:

-

This method will only return the available video bitrates of the -Period that is currently playing.

-

–

-

In DirectFile mode (see loadVideo -options), returns an empty Array.

-

Example

-
const videoBitrates = player.getAvailableVideoBitrates();
-if (videoBitrates.length) {
-  console.log(
-    "The current video is available in the following bitrates",
-    videoBitrates.join(", ")

arguments:

-
    -
  • minBitrate (Number): Lower video bitrate limit when adaptive streaming -is enabled.
    • -
-

–

-

Set a minimum video bitrate reachable through adaptive streaming.

-

When the bitrate is chosen through adaptive streaming (i.e., not enforced -manually through APIs such as setVideoBitrate), the player will never switch -to a video quality with a bitrate lower than that value.

-

The exception being when no quality has a higher bitrate, in which case the -maximum quality will always be chosen instead.

-

For example, if you want that video qualities chosen automatically never have -a bitrate below 100 kilobits per second you can call:

-
player.setMinVideoBitrate(100000);
-
-

Any limit can be removed just by setting that value to 0:

-
// remove video bitrate lower limit
-player.setMinVideoBitrate(0);
-
-

The effect of this method is persisted from content to content. As such, it can -even be called when no content is currently loaded.

-

Note that this only affects adaptive strategies. Forcing the bitrate manually -(for example by calling setVideoBitrate) bypass this limit completely.

    • -
-

–

-

Set a maximum video bitrate reachable through adaptive streaming.

-

When the bitrate is chosen through adaptive streaming (i.e., not enforced -manually through APIs such as setVideoBitrate), the player will never switch -to a video quality with a bitrate higher than that value.

-

The exception being when no quality has a lower bitrate, in which case the -minimum quality will always be chosen instead.

-

For example, if you want that video qualities chosen automatically never have -a bitrate higher than 1 Megabits per second you can call:

setVideoBitrate

-

–

-

syntax: player.setVideoBitrate(bitrate)

-

arguments:

-
    -
  • bitrate (Number): Optimal video bitrate (the quality with the maximum -bitrate inferior to this value will be chosen if it exists).
    • -
-

–

-

Force the current video track to be of a certain bitrate.

-

If a video quality in the current track is found with the exact same bitrate, -this quality will be set.

-

If no video quality is found with the exact same bitrate, either:

-
    -
  • -

    the video quality with the closest bitrate inferior to that value will be -chosen.

    -
    • -
  • -

    if no video quality has a bitrate lower than that value, the video -quality with the lowest bitrate will be chosen instead.

    -
    • -
-

By calling this method with an argument set to -1, this setting will be -disabled and the RxPlayer will chose the right quality according to its adaptive -logic.

-

You can use getAvailableVideoBitrates to get the list of available bitrates -for the current video track.

-

Note that the value set is persistent between loadVideo calls. -As such, this method can also be called when no content is playing (the same -rules apply for future contents).

    -
    • -
-

By calling this method with an argument set to -1, this setting will be -disabled and the RxPlayer will chose the right quality according to its adaptive -logic.

-

You can use getAvailableAudioBitrates to get the list of available bitrates -for the current audio track.

-

Note that the value set is persistent between loadVideo calls. -As such, this method can also be called when no content is playing (the same -rules apply for future contents).

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

getManualVideoBitrate

-

–

-

syntax: const currentManualVideoBitrate = player.getManualVideoBitrate()

-

return value: Number

-

–

-

Get the last video bitrate manually set. Either via setVideoBitrate or via -the initialVideoBitrate constructor option.

-

This value can be different than the one returned by getVideoBitrate:

-
    -
  • getManualVideoBitrate returns the last bitrate set manually by the user
    • -
  • getVideoBitrate returns the actual bitrate of the current video track
    • -
-

-1 when no video bitrate is forced.

-

-

-

getManualAudioBitrate

-

–

-

syntax: const currentManualAudioBitrate = player.getManualAudioBitrate()

-

return value: Number

-

–

-

Get the last audio bitrate manually set. Either via setAudioBitrate or via -the initialAudioBitrate constructor option.

-

This value can be different than the one returned by getAudioBitrate:

-
    -
  • getManualAudioBitrate returns the last bitrate set manually by the user
    • -
  • getAudioBitrate returns the actual bitrate of the current audio track
    • -
-

-1 when no audio bitrate is forced.

-

-

-

Buffer control

-

The methods in this chapter allow to get and set limits on how the current -buffer can grow.

-

-

-

setWantedBufferAhead

-

–

-

syntax: player.setWantedBufferAhead(bufferGoal)

-

arguments:

-
    -
  • bufferGoal (Number): Ideal amount of buffer that should be pre-loaded, -in seconds.
    • -
-

–

-

Set the buffering goal, as a duration ahead of the current position, in seconds.

-

Once this size of buffer reached, the player won’t try to download new segments -anymore.

-

By default, this value is set to 30.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

getWantedBufferAhead

-

–

-

syntax: const bufferGoal = player.getWantedBufferAhead()

-

return value: Number

-

–

-

returns the buffering goal, as a duration ahead of the current position, in -seconds.

-

By default, this value is set to 30.

-

-

-

setMaxBufferBehind

-

–

-

syntax: player.setMaxBufferBehind(bufferSize)

-

arguments:

-
    -
  • bufferSize (Number): Maximum amount of buffer behind the current -position, in seconds.
    • -
-

–

-

Set the maximum kept buffer before the current position, in seconds.

-

Everything before that limit (currentPosition - maxBufferBehind) will be -automatically garbage collected.

-

This feature is not necessary as the browser should by default correctly -remove old segments from memory if/when the memory is scarce.

-

However on some custom targets, or just to better control the memory footprint -of the player, you might want to set this limit.

-

You can set it to Infinity to remove this limit and just let the browser do -this job instead.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

getMaxBufferBehind

-

–

-

syntax: const bufferSize = player.getMaxBufferBehind()

-

return value: Number

-

–

-

Returns the maximum kept buffer before the current position, in seconds.

-

This setting can be updated either by:

-
    -
  • calling the setMaxBufferBehind method.
    • -
  • instanciating an RxPlayer with a maxBufferBehind property set.
    • -
-

-

-

setMaxBufferAhead

-

–

-

syntax: player.setMaxBufferAhead(bufferSize)

-

arguments:

-
    -
  • bufferSize (Number): Maximum amount of buffer ahead of the current -position, in seconds.
    • -
-

–

-

Set the maximum kept buffer ahead of the current position, in seconds.

-

Everything superior to that limit (currentPosition + maxBufferAhead) will -be automatically garbage collected.

-

This feature is not necessary as the browser should by default correctly -remove old segments from memory if/when the memory is scarce.

-

However on some custom targets, or just to better control the memory footprint -of the player, you might want to set this limit.

-

You can set it to Infinity to remove any limit and just let the browser do -this job instead.

-

The minimum value between this one and the one returned by -getWantedBufferAhead will be considered when downloading new segments.

-

⚠️ Bear in mind that a too-low configuration there (e.g. inferior to -10) might prevent the browser to play the content at all.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

getMaxBufferAhead

-

–

-

syntax: const bufferSize = player.getMaxBufferAhead()

-

return value: Number

-

–

-

Returns the maximum kept buffer ahead of the current position, in seconds.

This setting can be updated either by:

-
    -
  • calling the setMaxBufferAhead method.
    • -
  • instanciating an RxPlayer with a maxBufferAhead property set.
    • -
-

-

-

Buffer information

  • the start of the current contiguous loaded range.
    • -
  • the end of it.
    • -
-

In other words, this is the duration of the current contiguous range of media -data the player is currently playing: -If we’re currently playing at the position at 51 seconds, and there is media -data from the second 40 to the second 60, then getVideoLoadedTime() will -return 20 (60 - 40).

  • the start of the current contiguous loaded range.
    • -
  • the current time.
    • -
-

In other words, this is the amount of time in the current contiguous range of -media data the player has already played. -If we’re currently playing at the position at 51 seconds, and there is media -data from the second 40 to the second 60, then getVideoPlayedTime() will -return 11 (51 - 40).

-

0 if there’s no data loaded for the current position.

  • the current time.
    • -
  • the end of the current contiguous loaded range.
    • -
-

In other words, this is the amount of seconds left in the buffer before the end -of the current contiguous range of media data. -If we’re currently playing at the position at 51 seconds, and there is media -data from the second 40 to the second 60, then getVideoPlayedTime() will -return 9 (60 - 51).

-

-

Static properties

-

This chapter documents the static properties that can be found on the RxPlayer -class.

-

-

-

version

-

type: Number

-

The current version of the RxPlayer.

-

-

-

ErrorTypes

-

type: Object

-

The different “types” of Error you can get on playback error,

-

See the Player Error documentation for more information.

-

-

-

ErrorCodes

-

type: Object

-

The different Error “codes” you can get on playback error,

-

See the Player Error documentation for more information.

-

-

-

LogLevel

-

type: string

-

default: "NONE"

-

The current level of verbosity for the RxPlayer logs. Those logs all use the -console.

-

From the less verbose to the most:

-
    -
  • -

    "NONE": no log

    -
    • -
  • -

    "ERROR": unexpected errors (via console.error)

    -
    • -
  • -

    "WARNING": The previous level + minor problems encountered (via -console.warn)

    -
    • -
  • -

    "INFO": The previous levels + noteworthy events (via console.info)

    -
    • -
  • -

    "DEBUG": The previous levels + normal events of the player (via -console.log)

    -
    • -
-

If the value set to this property is different than those, it will be -automatically set to "NONE".

-

Example

-
import RxPlayer from "rx-player";
-RxPlayer.LogLevel = "WARNING";
-
-

-

-

Tools

-

The RxPlayer has several “tools”, which are utils which can be imported without -importing the whole RxPlayer itself.

-

They are all documented here.

-

-

-

StringUtils

-

Tools to convert strings into bytes and vice-versa.

-

The RxPlayer internally has a lot of code dealing with strings to bytes -conversion (and vice-versa). This tool exports that logic so you don’t have to -rewrite it yourself.

-

You might need one of those functions for example when dealing with challenge -and licenses, which are often under a binary format.

-

How to import it

-

The simplest way to import the StringUtils is by importing it as a named export -from “rx-player/tools”, like so:

-
import { StringUtils } from "rx-player/tools";
-
-console.log(StringUtils.strToUtf8("hello😀"));
-
-

You can also import only the function(s) you want to use by importing it -directly from “rx-player/tools/string-utils”:

-
import { strToUtf8 } from "rx-player/tools/string-utils";
-console.log(strToUtf8("hello😀"));
-
-

StringUtils functions

-

StringUtils is an object containing the following functions:

-
    -
  • -

    strToUtf8: Convert a JS string passed as argument to an Uint8Array of its -corresponding representation in UTF-8.

    -

    Example:

    -
    import { StringUtils } from "rx-player/tools";
-StringUtils.strToUtf8("hello😀");
-// => Uint8Array(9) [ 104, 101, 108, 108, 111, 240, 159, 152, 128 ]
-//                    "h"  "e"  "l"  "l"  "o"  "grinning face" emoji
-
    -
    • -
  • -

    utf8ToStr: Convert a Uint8Array containing a string encoded with UTF-8 -into a JS string.

    -

    Example:

    -
    import { StringUtils } from "rx-player/tools";
-const uint8Arr = new Uint8Array([104, 101, 108, 108, 111, 240, 159, 152, 128]);
-StringUtils.utf8ToStr(uint8Arr);
-// => "hello😀"
-
    -

    Note: if what you have is an ArrayBuffer, you have to convert it to an -Uint8Array first:

    -
    import { StringUtils } from "rx-player/tools";
-const toUint8Array = new Uint8Array(myArrayBuffer);
-console.log(StringUtils.utf8ToStr(toUint8Array));
-
    -
    • -
  • -

    strToUtf16LE: Convert a JS string passed as argument to an Uint8Array -containing its corresponding representation in UTF-16-LE (little endian -UTF-16).

    -

    Example:

    -
    import { StringUtils } from "rx-player/tools";
-StringUtils.strToUtf16LE("hi😀");
-// => Uint8Array(9) [ 104, 0, 105, 0, 61, 216, 0, 222 ]
-//                    "h"     "i"     "grinning face" emoji
-
    -
    • -
  • -

    utf16LEToStr: Convert a Uint8Array containing a string encoded with -UTF-16-LE (little endian UTF-16) into a JS string.

    -

    Example:

    -
    import { StringUtils } from "rx-player/tools";
-const uint8Arr = new Uint8Array([104, 0, 105, 0, 61, 216, 0, 222]);
-StringUtils.utf16LEToStr(uint8Arr);
-// => "hi😀"
-
    -

    Note: if what you have is an ArrayBuffer, you have to convert it to an -Uint8Array first:

    -
    import { StringUtils } from "rx-player/tools";
-const toUint8Array = new Uint8Array(myArrayBuffer);
-console.log(StringUtils.utf16LEToStr(toUint8Array));
-
    -
    • -
  • -

    strToUtf16BE: Convert a JS string passed as argument to an Uint8Array -containing its corresponding representation in UTF-16-BE (big endian -UTF-16).

    -

    Example:

    -
    import { StringUtils } from "rx-player/tools";
-StringUtils.strToUtf16BE("hi😀");
-// => Uint8Array(9) [ 0, 104, 0, 105, 216, 61, 222, 0 ]
-//                    "h"     "i"     "grinning face" emoji
-
    -
    • -
  • -

    utf16BEToStr: Convert a Uint8Array containing a string encoded with -UTF-16-BE (big endian UTF-16) into a JS string.

    -

    Example:

    -
    import { StringUtils } from "rx-player/tools";
-const uint8Arr = new Uint8Array([0, 104, 0, 105, 216, 61, 222, 0]);
-StringUtils.utf16BEToStr(uint8Arr);
-// => "hi😀"
-
    -

    Note: if what you have is an ArrayBuffer, you have to convert it to an -Uint8Array first:

    -
    import { StringUtils } from "rx-player/tools";
-const toUint8Array = new Uint8Array(myArrayBuffer);
-console.log(StringUtils.utf16BEToStr(toUint8Array));
-

loadVideo options

-

-

-

Overview

-

This page describes the options given to the loadVideo method, which is the -method to use to load a new video.

-

These options take the form of a single objects with multiple properties, like -this:

-
// Simply loading a DASH MPD
-const options = {
-  transport: "dash",
-  url: myManifestUrl
-};
-player.loadVideo(options);
-
-

-

-

Properties

-

-

-

transport

-

type: string|undefined

-

The transport protocol used for this content. -This property is mandatory.

-

Can be either:

-
    -
  • -

    "dash" - for DASH contents

    -
    • -
  • -

    "smooth" - for Microsoft Smooth Streaming contents

    -
    • -
  • -

    "directfile" - for loading a video in DirectFile mode, which allows to -directly play media files (example: .mp4 or .webm files) without -using a transport protocol. With that option, you can even play HLS -contents on multiple browsers (mainly safari and iOS browsers).

    -

    ⚠️ In that mode, multiple APIs won’t have any effect. -This is documented in the documentation of each concerned method, option or -event in the API.

    -
    • -
  • -

    "metaplaylist" for MetaPlaylist streams, which are -a concatenation of multiple smooth and DASH contents

    -
    • -
  • -

    "local" for local manifests, which allows to play -downloaded DASH, Smooth or MetaPlaylist contents (when offline for example).

    -
    • -
-

Example:

-
// play some dash content
-rxPlayer.loadVideo({
-  transport: "dash",
-  url: https://www.example.com/dash.mpd
-})
-
-

-

-

url

-

type: string|undefined

-

For Smooth, DASH or MetaPlaylist contents, the URL to the -Manifest (or equivalent)

-

For DirectFile mode contents, the URL of the content (the supported contents -depends on the current browser).

-

This property is mandatory unless either:

-
    -
  • -

    a manifestLoader is defined in the -transportOptions, in which case that callback will -be called instead any time we want to load the Manifest.

    -
    • -
  • -

    an initialManifest is defined in the -transportOptions, in which case this will be used -as the first version of the Manifest. -Note however that if the Manifest needs to be refreshed and no url nor -manifestLoader has been set, the RxPlayer will most likely fail and stop -playback.

    -
    • -
-

Example:

-
// play some dash content
-rxPlayer.loadVideo({
-  url: https://www.example.com/dash.mpd,
-  transport: "dash"
-})
-
-

-

-

keySystems

-

type: Array.<Object>|undefined

-

This property is mandatory if the content uses DRM.

-

It is here that is defined every options relative to the encryption of your -content. There’s a lot of configuration possible here. In the case you find -this documentation hard to grasp, we’ve written a tutorial on DRM configuration -here.

-

This property is an array of objects with the following properties (only -type and getLicense are mandatory here):

-
    -
  • -

    type (string): name of the DRM system used. Can be either -"widevine", "playready" or clearkey or the type (reversed domain -name) of the keySystem (e.g. "com.widevine.alpha", -"com.microsoft.playready" …).

    -
    • -
  • -

    getLicense (Function): Callback which will be triggered everytime a -message is sent by the Content Decryption Module (CDM), usually to -fetch/renew the license.

    -

    Gets two arguments when called:

    -
      -
    1. the message (Uint8Array): The message, formatted to an Array of -bytes.
      2. -
    2. the messageType (string): String describing the type of message -received. -There is only 4 possible message types, all defined in the w3c -specification.
      3. -
    -

    This function should return either synchronously the license, null to -not set a license for this message event or a Promise which should -either: -- resolves if the license was fetched, with the licence in argument -- resolve with null if you do not want to set a license for this -message event -- reject if an error was encountered.

    -

    Note: We set a 10 seconds timeout by default on this request (configurable -through the getLicenseConfig object). -If the returned Promise do not resolve or reject under this limit, the -player will stop with an error.

    -

    In any case, the license provided by this function should be of a -BufferSource type (example: an Uint8Array or an ArrayBuffer).

    -

    Even in case of an error, you can (this is not mandatory) set any of the -following properties on the rejected value which will be interpreted by -the RxPlayer:

    -
    - `noRetry` (`Boolean`): If set to `true`, we will throw directly a
-  `KEY_LOAD_ERROR` to call `getLicense`. If not set or set to `false`,
-  the current retry parameters will be applied (see `getLicenseConfig`)
-
-- `message` (`string`): If the `message` property is set as a "string",
-  this message will be set as the `message` property of the
-  corresponding `EncryptedMediaError` (either communicated through an
-  `"error"` event if we're not retrying or through a `"warning"` event
-  if we're retrying).
-  As every other `getLicense`-related errors, this error will have the
-  `KEY_LOAD_ERROR` `code` property.
-
-- `fallbackOnLastTry`: If this getLicense is the last retry (if the
-  `noRetry` property is set to `true`, this is always true), we will not
-  throw immediately but rather try to fallback on other Representations
-  (e.g. qualities) which might have a different decryption key. If no
-  Representation is left, we will throw a MediaError with a
-  `NO_PLAYABLE_REPRESENTATION` code, as documented [in the errors
-  documentation](./errors.md#types-media_error).
-
-  You will receive a `decipherabilityUpdate` event when we fallback from
-  a given Representation. You can find documentation on this event [in
-  the corresponding chapter of the events
-  documentation](./player_events.md#events-decipherabilityUpdate).
-
-  This option is thus only useful for contents depending on multiple
-  licenses.
-
-  When fallbacking, we might need to reload the current MediaSource,
-  leading to a black screen during a brief instant. When reloading, the
-  RxPlayer will have the `"reloading"` [player state](./states.md).
-  on most situations, we will however not reload the media source but
-  only perform a very little seek (of some milliseconds). you might see
-  the stream stutter for a very brief instant at that point.
-
-  On the Edge browser, we found an issue that can arise when this option
-  is set if PlayReady is used. This issue can make the player loads the
-  content indefinitely.
-  Sadly, no work-around has been found for now for this issue. We're
-  currently trying to create a reproducible scenario and document that
-  issue so it can hopefully be fixed in the future. In the meantime,
-  you're encouraged either to use Widevine (only on Chromium-based Edge)
-  or to not make use of the `fallBackOnLastTry` option on that browser.

    getLicenseConfig (Object|undefined): Optional configuration for the -getLicense callback. Can contain the following properties:

    -
      -
    • -

      retry (Number|undefined) (default: 2): number of time -getLicense is retried on error or on timeout before we fail on a -KEY_LOAD_ERROR

      -
      • -
    • -

      timeout (Number|undefined) (default: 10000): timeout, in ms, -after which we consider the getLicense callback to have failed.

      -

      Set it to -1 to disable any timeout.

      -
      • -
    -
    • -
  • -

    serverCertificate (BufferSource|undefined): Eventual certificate -used to encrypt messages to the license server. -If set, we will try to set this certificate on the CDM. If it fails, we will -still continue to try deciphering the content (albeit a -warning will be emitted in that case with the code -"LICENSE_SERVER_CERTIFICATE_ERROR").

    -
    • -
  • -

    persistentLicense (Boolean|undefined): Set it to true if you -want the ability to persist the license for later retrieval. -In that case, you will also need to set the licenseStorage attribute to -be able to persist the license through your preferred method. This is not -needed for most usecases.

    -
    • -
  • -

    licenseStorage (Object|undefined): Required only if -persistentLicense has been set to true. It’s an object containing -two functions load and save:

    -
      -
    • save: take into argument an Array.<Object> which will be the set -of sessionId to save. No return value needed.
      • -
    • load: take no argument and returns the stored Array.<Object> -(the last given to save) synchronously.
      • -
    -
    • -
  • -

    persistentStateRequired (Boolean|undefined): Set it to true if -the chosen CDM should have the ability to persist a license, false if -you don’t care. This is not needed for most usecases. false by default. -You do not have to set it to true if the persistentLicense option is -set.

    -
    • -
  • -

    distinctiveIdentifierRequired (Boolean|undefined): When set to -true, the use of -Distinctive Indentifier(s) -or -Distinctive Permanent Identifier(s) -will be required. This is not needed for most usecases. false if you do -not care. false by default.

    -
    • -
  • -

    throwOnLicenseExpiration (Boolean|undefined): true by default.

    -

    If set to true or not set, the playback will be interrupted as soon as one -of the current licenses expires. In that situation, you will be warned with -an error event with, as a payload, an error with the code -KEY_STATUS_CHANGE_ERROR.

    -

    If set to false, the playback of the current content will not be -interrupted even if one of the current licenses is expired. It might however -stop decoding in that situation. -It’s then up to you to update the problematic license, usually through the -usual getLicense callback.

    -

    You may want to set this value to false if a session expiration leads to -a license renewal. -In that case, content may continue to play once the license has been -updated.

    -
    • -
  • -

    fallbackOn (Object): This advanced option allows to fallback on other -Representations (e.g. qualities) when one of them has its decription key -refused.

    -

    This option is thus only useful for contents depending on multiple -keys.

    -

    This object can have two properties: -- keyInternalError: fallback when the corresponding key has the -status -"internal-error". We found that most widevine implementation use -this error when a key is refused. -- keyOutputRestricted: fallback when the corresponding key has the -status -"output-restricted". This is the proper status for a key refused due -to output restrictions.

    -

    For most cases where you want to fallback in case of a refused key, we -recommend setting both properties to true.

    -

    You will receive a decipherabilityUpdate event when we fallback from -a given Representation. You can find documentation on this event -in the corresponding chapter of the events -documentation.

    -

    When fallbacking, we might need to reload the current MediaSource, leading -to a black screen during a brief instant. When reloading, the RxPlayer -will have the "reloading" player state. -on most situations, we will however not reload the media source but only -perform a very little seek (of some milliseconds). you might see the -stream twitch for a very brief instant at that point.

    -

    If we have no Representation to fallback to anymore, we will throw a -MediaError with a NO_PLAYABLE_REPRESENTATION code, as documented in -the errors documentation.

    -
    • -
  • -

    onKeyStatusesChange (Function|undefined): Not needed for most -usecases.

    -

    Triggered each time the key statuses of the current session -changes, except for the following statuses (which throws immediately):

    -
      -
    • expired if (and only if) throwOnLicenseExpiration is not set to -false
      • -
    • internal-error
      • -
    -

    Takes 2 arguments:

    -
      -
    1. The keystatuseschange event {Event}
      2. -
    2. The session associated with the event {MediaKeySession}
      3. -
    -

    Like getLicense, this function should return a promise which emit a -license or null (for no license) when resolved. It can also return -directly the license or null if it can be done synchronously.

    -

    In case of an error, you can set the message property on the -rejected value as a “string”. This message will be set as the message -property of the corresponding EncryptedMediaError communicated through -an "error" event. -As every other onKeyStatusesChange-related errors, this error will have -the KEY_STATUS_CHANGE_ERROR code property.

    -
    • -
  • -

    closeSessionsOnStop (Boolean|undefined): If set to true, the -MediaKeySession created for a content will be immediately closed when -the content stops its playback. This might be required by your key system -implementation (most often, it is not).

    -

    If set to false or not set, the MediaKeySession can be reused if the -same content needs to be re-decrypted.

    -
    • -
  • -

    disableMediaKeysAttachmentLock (Boolean|undefined): -In regular conditions, we might want to wait for the media element to have -decryption capabilities (what we call here “MediaKeys attachment”) before -beginning to load the actual content.

    -

    Waiting for that capability validation allows for example to play a content -which contains both encrypted and unencrypted data on the Chrome browser.

    -

    However, we found that in some peculiar devices (like some set-top boxes) -this can create a deadlock: the browser sometimes wait for some -content to be loaded before validating the media element’s decryption -capabilities.

    -

    Because we didn’t find a good enough compromise for now, we added the -disableMediaKeysAttachmentLock boolean. -By setting it to true, we won’t wait for “MediaKeys attachment” before -pushing the first content. The downside being that content of mixed -unencrypted/encrypted data might not be playable with that configuration.

    -

    You can try that property if your encrypted contents seems to load -indefinitely on peculiar targets.

    -

Example

-

Example of a simple DRM configuration for widevine and playready DRMs:

-
player.loadVideo({
-  url: manifestURL,
-  transport: "dash",
-  keySystems: [{
-    type: "widevine",
-    getLicense(challenge) {
-      // ajaxPromise is here an AJAX implementation doing a POST request on the
-      // widevineLicenseServer with the challenge in its body.
-      return ajaxPromise(widevineLicenseServer, challenge);
-    }
-  }, {
-    type: "playready",
-    getLicense(challenge) {
-      // idem
-      // Note: you may need to format the challenge before doing the request
-      // depending on the server configuration.
-      return ajaxPromise(playreadyLicenseServer, challenge);
-    }
-  }]
-})
-
-

-

-

autoPlay

-

type: Boolean|undefined

-

defaults: false

-

If set to true, the video will play immediately after being loaded.

-

Note: On some browsers, auto-playing a media without user interaction is blocked -due to the browser’s policy. -In that case, the player won’t be able to play (it will stay in a "LOADED" -state) and you will receive a warning event containing a -MEDIA_ERROR with the code: MEDIA_ERR_BLOCKED_AUTOPLAY. -A solution in that case would be to propose to your users an UI element to -trigger the play with an interaction.

-

-

-

startAt

-

type: Object|undefined

-

startAt allows to define a starting position in the played content whether -it is a live content or not.

-

This option is only defining the starting position, not the beginning of the -content. The user will then be able to navigate anywhere in the content through -the seekTo API.

-

If defined, this property must be an object containing a single key. This key -can be either:

-
    -
  • -

    position (Number): The starting position, in seconds.

    -
    • -
  • -

    wallClockTime (Number|Date): The starting wall-clock time (re-scaled -position from Manifest information to obtain a -timestamp on live contents), in seconds. -Useful to use the type of time returned by the getWallClockTime API for -live contents. If a Date object is given, it will automatically be converted -into seconds.

    -
    • -
  • -

    fromFirstPosition (Number): relative position from the minimum -possible one, in seconds. -That is:

    -
      -
    • for dynamic (live) contents, from the beginning of the buffer depth (as -defined by the Manifest).
      • -
    • for non-dynamic (vod) contents, from the position 0 (this option -should be equivalent to position)
      • -
    -
    • -
  • -

    fromLastPosition (Number): relative position from the maximum -possible one, in seconds. Should be a negative number:

    -
      -
    • for dynamic (e.g. live) contents, it is the difference between the -starting position and the currently last possible position, as defined -by the manifest.
      • -
    • for VoD contents, it is the difference between the starting position and -the end position of the content.
      • -
    -
    • -
  • -

    percentage (Number): percentage of the wanted position. 0 being -the minimum position possible (0 for static content, buffer depth for -dynamic contents) and 100 being the maximum position possible -(duration for VoD content, last currently possible position for dynamic -contents).

    -
    • -
-

Note: Only one of those properties will be considered, in the same order of -priority they are written here.

-

If the value set is inferior to the minimum possible position, the minimum -possible position will be used instead. If it is superior to the maximum -possible position, the maximum will be used instead as well.

-

More information on how the initial position is chosen can be found in the -specific documentation page on this subject.

-

Notes for dynamic contents

-

For dynamic contents, startAt could work not as expected:

-
    -
  • -

    Depending on the type of Manifest, it will be more or less precize to guess -the current last position of the content. This will mostly affect the -fromLastPosition option.

    -
    • -
  • -

    If the Manifest does not allow to go far enough in the past (not enough -buffer, server-side) to respect the position wanted, the maximum buffer -depth will be used as a starting time instead.

    -
    • -
  • -

    If the Manifest does not allow to go far enough in the future to respect the -position wanted, the current last available position will be used to define -the starting time instead.

    -
    • -
-

If startAt is not set on live contents, the time suggested by the Manifest -will be considered. If it is also not set, the initial position will be based on -the real live edge.

-

Example

-
// using position
-player.loadVideo({
-  // ...
-  startAt: {
-    position: 10 // start at position == 10 (in seconds)
-  }
-});
-
-// using wall-clock time
-player.loadVideo({
-  // ...
-  startAt: {
-    wallClockTime: Date.now() / 1000 - 60 // 1 minute before what's broadcasted
-                                          // now
-  }
-});
-
-// using fromFirstPosition
-player.loadVideo({
-  // ...
-  startAt: {
-    fromFirstPosition: 30 // 30 seconds after the beginning of the buffer
-  }
-})
-
-// using fromLastPosition
-player.loadVideo({
-  // ...
-  startAt: {
-    fromLastPosition: -60 // 1 minute before the end
-  }
-})
-
-

-

-

transportOptions

-

type: Object|undefined

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

Options concerning the “transport”.

-

That is, the part of the code:

-
    -
  • performing Manifest and segment requests
    • -
  • parsing the Manifest
    • -
  • parsing/updating/creating segments
    • -
-

This Object can contain multiple properties. Only those documented here are -considered stable:

-
    -
  • -

    minimumManifestUpdateInterval (number|undefined):

    -

    Set the minimum time, in milliseconds, we have to wait between Manifest -updates.

    -

    A Manifest may need to be updated in regular intervals (e.g. many DASH -dynamic contents depend on that behavior).

    -

    The frequency at which we normally update a Manifest depends on multiple -factors: the information taken from the Manifest, the transport chosen or -the current playback conditions. You might want to use -minimumManifestUpdateInterval to limit that frequency to a minimum.

    -

    This option is principally useful on some embedded devices where resources -are scarce. The request and data decompression done at each Manifest update -might be too heavy for some and reducing the interval at which they are done -might help.

    -

    Please note however than reducing that frequency can raise the chance of -rebuffering, as we might be aware of newly generated segments later than we -would be without that option.

    -

    Example:

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {
-    minimumManifestUpdateInterval: 5000, // Perform Manifest updates at most
-                                         // every 5 seconds
-  }
-});
-
    -
    • -
  • -

    initialManifest (string|Document|Object):

    -

    Manifest that will be initially used (before any potential Manifest -refresh).

    -

    Some applications pre-load the Manifest to parse some information from it -before calling loadVideo. -As in that case the Manifest has already been loaded, an application can -optimize content loading time by giving to the RxPlayer that already-loaded -Manifest so the latter can avoid doing another request for it.

    -

    The format accepted for that option depends on the current chosen -transport:

    -
      -
    • -

      for "dash" and "smooth" contents either a string (of the whole -Manifest’s xml data) or a corresponding Document format is accepted.

      -
      • -
    • -

      for "metaplaylist", either a string (for the whole JSON) or the -corresponding JS Object is accepted.

      -
      • -
    • -

      for "local", only the corresponding local Manifest as a JS object is -accepted.

      -
      • -
    -

    Note that using this option could have implications for live contents. -Depending on the content, the initial playing position and maximum position -could be calculated based on that option’s value.

    -

    In a case where the corresponding Manifest request was performed long before -the loadVideo call, the RxPlayer could be for example initially playing -far from the real live edge. -Because of that, it is recommended to only set that options for live/dynamic -contents if its request was done immediately before the loadVideo -call.

    -
    • -
  • -

    manifestUpdateUrl (string|undefined):

    -

    Set a custom Manifest URL for Manifest updates. -This URL can point to another version of the Manifest with a shorter -timeshift window, to lighten the CPU, memory and bandwidth impact of -Manifest updates.

    -

    Example:

    -
    rxPlayer.loadVideo({
-  transport: "dash",
-  url: "https://example.com/full-content.mpd",
-  transportOptions: {
-    manifestUpdateUrl: "https://example.com/content-with-shorter-window.mpd"
-  }
-});
-
    -

    When the RxPlayer plays a live content, it may have to refresh frequently -the Manifest to be aware of where to find new media segments. -It generally uses the regular Manifest URL when doing so, meaning that the -information about the whole content is downloaded again.

    -

    This is generally not a problem though: The Manifest is generally short -enough meaning that this process won’t waste much bandwidth memory or -parsing time. -However, we found that for huge Manifests (multiple MB uncompressed), this -behavior could be a problem on some low-end devices (some set-top-boxes, -chromecasts) where slowdowns can be observed when Manifest refresh are -taking place.

    -

    The manifestUpdateUrl will thus allow an application to provide a second -URL, specifically used for Manifest updates, which can represent the same -content with a shorter timeshift window (e.g. using only 5 minutes of -timeshift window instead of 10 hours for the full Manifest). The content -will keep its original timeshift window and the RxPlayer will be able to get -information about new segments at a lower cost.

    -
    • -
  • -

    representationFilter (Function|undefined):

    -

    Allows to filter out Representations (i.e. media qualities) from the -Manifest to avoid playing them.

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {
-    representationFilter(representations, infos) {
-      // ...
-    }
-  }
-});
-
    -

    More infos on it can be found here.

    -
    • -
  • -

    segmentLoader (Function|undefined):

    -

    Defines a custom segment loader for when you want to perform the requests -yourself.

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {
-    segmentLoader(infos, callbacks) {
-      // logic to download a segment
-    }
-  }
-});
-
    -

    More info on it can be found here.

    -
    • -
  • -

    manifestLoader (function|undefined):

    -

    Defines a custom Manifest loader (allows to set a custom logic for the -Manifest request).

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {
-    manifestLoader(url, callbacks) {
-      // logic to fetch the Manifest
-    }
-  }
-});
-
    -

    More info on it can be found here.

    -
    • -
  • -

    checkMediaSegmentIntegrity (boolean|undefined):

    -

    If set to true, the RxPlayer will retry a media segment request if that -segment seems corrupted.

    -

    If not set or set to false, the RxPlayer might interrupt playback in the -same situation.

    -

    You can set this option if you suspect the CDN providing your contents to -sometimes send you incomplete/corrupted segments.

    -

    Example:

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {
-    checkMediaSegmentIntegrity: true,
-  }
-});
-
    -
    • -
  • -

    serverSyncInfos (Object|undefined):

    -

    Allows to provide a time synchronization mechanism between the client and -the server.

    -

    This value is mainly useful for live DASH contents based on a -SegmentTemplate scheme without SegmentTimeline elements as those rely on -having a synchronized clock on the client side.

    -

    The serverSyncInfos object contains two keys:

    -
      -
    • -

      serverTimestamp (number): Unix timestamp of the server at a given -point in time, in milliseconds.

      -
      • -
    • -

      clientTime (number): Value of the performance.now() API at the time -the serverTimestamp value was true. Please note that if your page contains -multiple worker, the performance.now() call should be done on the same -worker than the one in which loadVideo is called.

      -

      The performance.now() API is used here because it is the main API to -obtain a monotically increasing clock on the client-side.

      -
      • -
    -

    Example:

    -
    const timeResponse = await fetch(timeServerURL);
-const clientTime = performance.now();
-const serverTimestamp = await timeResponse.text();
-const serverSyncInfos = { serverTimestamp, clientTime };
-rxPlayer.loadVideo({
-  // ...
-  transportOptions: { serverSyncInfos }
-})
-
    -

    If indicated, we will ignore any time indication on the MPD and only consider -serverSyncInfos to calculate the time on the server side.

    -

    This value is also very useful for low-latency contents, as some of them do not -indicate any server’s time, relying on the client one instead.

    -

    Note that there is a risk of us losing synchronization when leap seconds are -added/substracted to unix time. However we consider those situations rare enough -(and the effect should be relatively weak) to let this as is for the moment. For -a complete explanation, you can look at the corresponding chapter of the -low-latency documentation.

    -
    • -
  • -

    aggressiveMode (boolean|undefined):

    -

    If set to true, we will try to download segments very early, even if we are -not sure they had time to be completely generated.

    -

    For the moment, this mode has only an effect for all Smooth contents and -some DASH contents relying on a number-based SegmentTemplate segment -indexing scheme.

    -

    The upside is that you might have the last segments sooner. -The downside is that requests for segments which did not had time to -generate might trigger a NetworkError. Depending on your other settings -(especially the networkConfig loadVideo options), those errors might just -be sent as warnings and the corresponding requests be retried.

    -

    Example:

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {
-    aggressiveMode: true,
-  }
-});
-
    -
    • -
  • -

    referenceDateTime (number|undefined):

    -

    Only useful for live contents. This is the default amount of time, in -seconds, to add as an offset to a given media content’s time, to obtain the -real live time.

    -

    For example, if the media has it’s 0 time corresponding to the 30th of -January 2010 at midnight, you can set the referenceDateTime to new Date(2010-01-30) / 1000. This value is useful to communicate back to you -the “live time”, for example through the getWallClockTime method.

    -

    This will only be taken into account for live contents, and if the Manifest -/ MPD does not already contain an offset (example: an -“availabilityStartTime” attribute in a DASH MPD).

    -

    Example:

    -
    rxPlayer.loadVideo({
-  // ...
-  transportOptions: {

textTrackMode

-

type: string

-

defaults: "native"

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

This option allows to specify how the text tracks should be displayed.

-

There is two possible values:

-
    -
  • "native"
    • -
  • "html"
    • -
-

In the default "native" mode, a <track> element will be created on the -video and the subtitles will be displayed by it, with a minimal style. -There is no action on your side, the subtitles will be correctly displayed at -the right time.

-

In "html" mode, the text tracks will be displayed on a specific HTML -element. This mode allows us to do much more stylisation, such as the one -defined by TTML styling attributes or SAMI’s CSS. It is particularly useful to -correctly manage complex closed captions (with multiple colors, positionning -etc.). -With this mode, you will need to provide a wrapper HTML element with the -textTrackElement option.

-

All text track formats supported in "native" mode also work in "html" -mode.

-

More infos on supported text tracks can be found in the text track -documentation.

-

-

-

textTrackElement

-

type: HTMLElement

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

textTrackElement is only required and used if you provided a "html" -textTrackMode.

-

This property will be the element on which text tracks will be set, as child -elements, at the right time. We expect that this element is the exact same size -than the media element it applies to (this allows us to properly place the -subtitles position without polling where the video is in your UI). -You can however re-size or update the style of it as you wish, to better suit -your UI needs.

-

-

-

audioTrackSwitchingMode

-

type: string

-

defaults: "seamless"

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

Behavior taken by the player when switching to a different audio track, through -the setAudioTrack method.

-

There are two possible values:

-
    -
  • -

    "seamless": The transition between the old audio track and the new one -happens seamlessly, without interruption. -This is the default behavior.

    -

    As an inconvenient, you might have at worst a few seconds in the previous -audio track before the new one can be heard.

    -
    • -
  • -

    "direct": The player will try to switch to the new audio track as soon -as possible, which might lead to an interruption while it is doing so.

    -

    Note that while switching audio track with a "direct" -audioTrackSwitchingMode, it is possible that the player goes into the -"RELOADING" state (during which the video will disappear and many APIs -will become unavailable) to be able to switch to the new track.

    -

    More information about the "RELOADING" state can be found in the -player states documentation.

manualBitrateSwitchingMode

-

type: string

-

defaults: "seamless"

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

Strategy you want to adopt when updating “manually” the video and audio quality -through respectively the setVideoBitrate and setAudioBitrate API while -the content is playing.

-

There is two possible values:

-
    -
  • -

    "seamless": Manual quality updates will be only visible after a little -time. This gives the advantage of a very smooth “seamless” transition.

    -

    In this mode, you will have the following behavior:

    -
      -
    • there will be no visual “cut” between the previous and new quality
      • -
    • parts of the content with a better (or the same) quality won’t be -replaced.
      • -
    • parts of the content with a lower quality will be only replaced when the -better quality is downloaded.
      • -
    -
    • -
  • -

    "direct": Manual quality updates will be visible more directly, but with -a complete reload of the current content. You might encounter a black screen -while the player go through the "RELOADING" state [1].

    -

    In this mode, you will have the following behavior:

    -
      -
    • there will be a black screen between the previous and new quality
      • -
    • the previous content will be entirely removed
      • -
    • you will only have content with the new quality
      • -
    -

    [1] More information about the "RELOADING" state can be found in the -player states documentation.

onCodecSwitch

-

type: string

-

defaults: "continue"

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

Behavior taken by the player when switching to either an audio or video track -which has a codec “incompatible” with the previous one (for example going from -avc, a.k.a h264 to hevc, a.k.a. h265).

-

This switch can either after the user switches from one track to another or -after encountering a new Period in some transport technologies (concept existing -for DASH, “local” and MetaPlaylist contents).

-

Can be set to one of those two values:

-
    -
  • -

    "continue": try to have a seamless transition between both codecs. -This behavior works on most modern browsers but might lead to problems like -infinite buffering and decoding errors on older browsers and peculiar -platforms. -This is the default behavior.

    -
    • -
  • -

    "reload": When switching from one codec to another - incompatible - one, -the RxPlayer will “reload” the content: the player will go into the -"RELOADING" state for a small amount of time, during which the video will -disappear and many APIs will become unavailable, before playing the track -with the new codec. -That behavior has the advantage of working on any platform but disadvantage -of having a visible transition when those type of codec switches happen.

    -

    Use it if you have issues with codec switching on some platforms.

    -

    More information about the "RELOADING" state can be found in the -player states documentation.

-

lowLatencyMode

-

type: Boolean

-

defaults: false

-

Allow to play DASH low-latency contents (with Chunk-encoded and -chunk-transferred CMAF segments) with a low latency efficiently.

-

In the some rare browsers who do not support the fetch API (like IE11 or the -BlackBerry browser), we might be more prone to rebuffering in that mode the -first few seconds. If you want to have a better experience on those browsers, -you might want to begin to play further from the live edge in those cases -through the startAt option.

-

More information on playing low-latency DASH contents can be found in the -corresponding documentation page.

-

networkConfig

-

type: Object

-

defaults: {}

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

Configuration linked to Manifest and segment requests. -This object can take the following properties (all are optional):

-
    -
  • -

    segmentRetry (Number): Maximum number of times a segment request -will be retried when an error happen - only on some condition [1].

    -

    Those retry will be done with a progressive delay, to avoid overloading a -CDN. When this count is reached, the player will stop and throw a fatal -error.

    -

    Defaults to 4.

    -
    • -
  • -

    manifestRetry (Number): Maximum number of times a Manifest request -will be retried when a request error happen - only on some condition [1]. -Defaults to 4.

    -

    Those retry will be done with a progressive delay, to avoid overloading a -CDN. When this count is reached, the player will stop and throw a fatal -error.

    -

    Defaults to 4.

    -
    • -
  • -

    offlineRetry (Number): Maximum number of times a request will be -retried when the request fails because the user is offline.

    -

    Those retry will be done with a progressive delay, to avoid overloading the -user’s ressources. When this count is reached, the player will stop and -throw a fatal error.

    -

    Defaults to Infinity.

    -
    • -
-

[1] To retry a request, one of the following condition should be met:

-
    -
  • -

    The request failed because of a 404 HTTP code

    -
    • -
  • -

    The request failed because of an HTTP code in the 500 family

    -
    • -
  • -

    The request failed because of a timeout

    -
    • -
  • -

    the request failed because of an unknown XHR error (might be a -parsing/interface error)

enableFastSwitching

-

type: boolean

-

defaults: true

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

Enable (when set to true and by default) or disable (when set to false) the -“fast-switching” feature.

-

“Fast-switching” is an optimization which allows the RxPlayer to replace -low-quality segments (i.e. with a low bitrate) with higher-quality segments -(higher bitrate) in the buffer in some situations.

-

This is used for example to obtain a faster quality transition when the user’s -network bandwidth raise up: instead of pushing the new high-quality segments at -the end of the current buffer, we push them much sooner - “on top” of already -pushed low-quality segments - so the user can quickly see the better quality.

-

In most cases, this is a feature you want. On some rare devices however, -replacing segments is poorly supported. -We’ve for example seen on a few devices that old replaced segments were still -decoded (and not the new better-quality segments that should have replaced -them). On other devices, replacing segments resulted in visible small decoding -issues.

-

Setting enableFastSwitching to false thus allows to disable the -fast-switching behavior. Note that it is - sadly - difficult to know when you -need to disable it. -In the great majority of cases, enabling fast-switching (the default behavior) -won’t lead to any problem. So we advise to only disable it when you suspect that -segment replacement when the quality raises is at the source of some issues -you’re having (in which case it will help to see if that’s really the case).

-

It is also important to add that setting enableFastSwitching to false only -disable the fast-switching feature and not all the logic where the RxPlayer is -replacing segments it already pushed to the buffer. -Forbiding the RxPlayer to replace segments altogether is today not possible and -would even break playback in some situations: when multi-Period DASH contents -have overlapping segments, when the browser garbage-collect partially a -segment…

-
-

type: Boolean

-

defaults: false

-
-

⚠️ This option has no effect in DirectFile mode (see transport -option).

-
-

If set to true, the eventual element will be put on mode hidden -when added to the video element, so it won’t actually display the subtitles the -rx-player add to it.

-

This has an effect only if:

-
    -
  • -

    the current textTrackMode is equal to "native" (see textTrackMode -option)

    -
    • -

Local contents (offline playback)

-

-

Preamble

-

The RxPlayer is also able to load downloaded DASH, Smooth, MetaPlaylist or even -HLS (CMAF-based) contents, whether it is for offline playback or just for an -online seamless playback without buffering.

-

This documentation page will be about how to load already downloaded contents. -We suppose the content is already downloaded and that you just want to play it -through the RxPlayer.

-

However, a tool to download DASH/Smooth/MetaPlaylist contents compatible to this -API is under way.

-

-

Overview

-

To play contents stored locally, the RxPlayer uses its own Manifest format - the -“local manifest” which is close in semantics to DASH’s own Manifest file, the -MPD.

-

This new Manifest format will be the only element you will need to generate on -your side to play stored contents. As such, this what most of this documentation -page is about.

-

Note that the wanted content does not need to be completely downloaded before -creating this local manifest. Playback can even begin while the content is -still downloading.

-

You will just need to:

-
    -
  1. indicate that this is a “local” content by setting the transport option -in loadVideo to "local"
    2. -
  2. As the generated Manifest object most likely won’t be available through an -URL but directly as a JavaScript object, you will need to communicate it -through the manifestLoader property in the transportOptions loadVideo -option.
    3. -
-

Here is an example:

-
rxPlayer.loadVideo({
-  transport: "local",
-  transportOptions: {
-    // Note: `_url` here will be `undefined`
-    manifestLoader(_url, callbacks) {
-      // where `localManifest` is the local Manifest in object form
-      callbacks.resolve({ data: localManifest });
-    }
-  }
-  // ...
-});
-
-

More infos on the manifestLoader can be found -here.

-

-

How to import this feature

-

The "LOCAL_MANIFEST" feature is not included in the default RxPlayer build.

-

There’s two way you can import it, depending on if you’re relying on the minimal -version or if you prefer to make use of environment variables and build the -player manually.

-

Through the minimal version of the RxPlayer

-

If you’re using the “minimal” version of the RxPlayer (through the -"rx-player/minimal" import), you will need to import the LOCAL_MANIFEST -experimental feature:

-
import RxPlayer from "rx-player/minimal";
-import { LOCAL_MANIFEST } from "rx-player/experimental/features";
-
-RxPlayer.addFeatures([LOCAL_MANIFEST]);
-
-

Through environment variables

-

If you don’t want to go the minimal version’s route and you have no problem with -building yourself a new version of the RxPlayer, you can make use of environment -variables to activate it.

-

This can be done through the RXP_LOCAL_MANIFEST environment variable, which -you have to set to true:

-
RXP_LOCAL_MANIFEST=true npm run build:min
-
-

More information about any of that can be found in the minimal player -documentation.

-

-

The Manifest format

-

As explained in the overview, offline playback by the RxPlayer mainly rely on a -specific sort of manifest, called the “local manifest”.

-

It is not the task of the RxPlayer to download and store the content here (a -tool to do just that is on its way), this page only explains how to play a -stored content once it has been stored.

-

The local manifest looks like a DASH MPD in its structure and as such is very -hierarchical.

-

It has the following structure:

-
manifest Object
-  ...manifest properties
-  period Object
-    ...period properties
-    adaptation Object
-      ...adaptation properties
-      representation Object
-        ...representation properties
-
-

We will go progressively from the elements higher in the hierarchy (the manifest -object) to the lower ones (the representation Object).

-

-

The manifest Object

-

The manifest object describes information about the whole local content:

-
    -
  • its duration
    • -
  • whether it is still downloading or if its completely available
    • -
  • the different “parts” (or “periods”) the content is divided in
    • -
-

First, let’s go into an example, before describing what each property is for:

-
{
-  type: "local", // always set to "local"
-  version: "0.2", // version number, in a MAJOR.MINOR form
-  minimumPosition: 0, // Minimum possible reachable position in the content,
-                      // in seconds
-  maximumPosition: 120, // Maximum possible reachable position in the content,
-                        // in seconds
-  isFinished: true, // if `false`, the content is still downloading
-  periods: [ // different "periods" in the content - see below
-    // ...
-  ],
-}
-
-

As you can see, it is a simple JavaScript object with few properties we’re going -to dive into just now.

-

-

properties

-

Here is the description about all the properties encountered in a local manifest -object:

-
    -
  • -

    type (string): Must be set to "local". This property indicates to the -RxPlayer that the current content is a local manifest.

    -
    • -
  • -

    version (string): Version number, in a MAJOR.MINOR form. -The present documentation is for the "0.2" version.

    -

    A parser for a version with the a given MAJOR version should be able to -parse and play contents for any of the corresponding MINOR versions.

    -

    The exception is the 0 MAJOR version (i.e. experimental versions). -A parser for a version with that major (let’s say 0.1) might be unable to -parse local Manifests of another version (e.g. 0.2).

    -
    • -
  • -

    minimumPosition (number|undefined): Optional minimum position reachable in -this content once it has been fully loaded, in seconds.

    -

    If not set or set to undefined, the RxPlayer will assume that the content -starts at a 0 position.

    -
    • -
  • -

    maximumPosition (number): Maximum position reachable in this content once -it has been fully loaded, in seconds.

    -
    • -
  • -

    isFinished (boolean): true indicates that the content has been -completely downloaded and can now be played as a whole. false indicates -that the whole content is not available yet and that the RxPlayer may have -to refresh the local manifest while playing (to get the new data).

    -
    • -
  • -

    periods (Array.<Object>): The different “periods” available in the -content. We will explain what a “period” is in the following chapter.

    -
    • -
  • -

    expired (Promise.<undefined>|undefined): Optional Promise which should -resolve when a newer local manifest is available.

    -

    This is for example useful when playing a content which is still -downloading. Here expired could resolve once a new segment is available, -the RxPlayer would then request the new local manifest (through the same API -than for the initial request, e.g. through the manifestLoader property -indicated in loadVideo) and would obtain a new local manifest with this -new segment included and a new expired property set. -This can go on until the content is completely downloaded at which time -expired can be set to undefined or just omitted from the last local -manifest.

    -
    • -
-

-

The period object

-

As seen in the previous chapter, the local manifest contains a periods -property. The concept of period comes from DASH and allow to separate a content -into multiple sub-parts, each with their own configurations.

-

For example, you could have in the same content a TV Show in german followed by -an american film, each with its own language choices and qualities.

-

If you don’t need that kind of granularity, you can just create a single period -for your local manifest.

-

Here’s an example of a period object:

-
{
-  start: 10, // starting position in the whole content, in seconds
-  end: 20, // ending position, in seconds
-  adaptations: [ // available tracks for this period
-    // ***
-  ]
-}
-
-

In the context of a local manifest with multiple periods, here is how it can -look like:

-
{
-  type: "local",
-  version: "0.2",
-  minimumPosition: 0,
-  maximumPosition: 60,
-  isFinished: true,
-  periods: [ // Here we have 3 consecutive periods:
-    {
-      start: 0,
-      end: 10,
-      adaptations: [ /* ... */ ]
-    },
-    {
-      start: 10,
-      end: 30,
-      adaptations: [ /* ... */ ]
-    },
-    {
-      start: 30,
-      end: 60,
-      adaptations: [ /* ... */ ]
-    },
-  ],
-}
-
-

-

properties

-

The following properties are found in a period object:

-
    -
  • -

    start (number): The position in seconds at which the period starts.

    -
    • -
  • -

    end (number): The position in seconds at which the period ends.

    -
    • -
  • -

    adaptations (Array.<Object>): The different tracks available. See below -for more information.

    -
    • -
-

-

the adaptation object

-

An adaptation is roughly a “track” of the content. It can for the moment be one -of those three types:

-
    -
  • “audio”
    • -
  • “video”
    • -
  • “text” (subtitles)
    • -
-

The form of the adaptation object depends on the type of track. Let’s just start -with a simple video track example:

-
{
-  type: "video",
-  language: "eng", // optional language code
-  representations: [ // describes the different available qualities
-    // ...
-  ]
-}
-
-

Let’s continue with an audio track example:

-
{
-  type: "audio",
-  language: "fra", // language code for this audio track
-  audioDescription: false, // if `true`, that audio track is a track adapted for
-                           // the visually impaired
-  representations: [ /* ... */ ]
-}
-
-

We’ll finish with a text track example:

-
{
-  type: "text",
-  language: "fra", // language code for this audio track
-  closedCaption: false, // if `true`, that text track contains supplementary
-                        // cues about the audio content (generally used for the
-                        // hard of hearing)
-  representations: [ /* ... */ ]
-}
-
-

Here how it looks when adaptations are integrated in a given period:

-
{
-  start: 0,
-  end: 10,
-  adaptations: [
-    {
-      type: "video",
-      representations: [ /* ... */ ],
-    },
-    {
-      type: "audio",
-      language: "eng",
-      audioDescription: false,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "audio",
-      language: "fra",
-      audioDescription: false,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "audio",
-      language: "fra",
-      audioDescription: true,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "text",
-      language: "fra",
-      closedCaption: false,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "text",
-      language: "fra",
-      closedCaption: true,
-      representations: [ /* ... */ ]
-    }
-  ]
-},
-
-

Let’s now describes precizely every properties encountered here.

-

-

properties

-

The following properties are found in an adaptation object:

-
    -
  • -

    type (string): The “type” of the current adaptation. Can be one of three -strings:

    -
      -
    1. audio
      2. -
    2. video
      3. -
    3. text -The two first ones are straightforward to understand, the third one -designates subtitles.
      4. -
    -
    • -
  • -

    language (string|undefined): When relevant, this string allows to define -the language code for the language the track is in. This is mostly useful -for audio and text adaptations but can also be defined for video tracks.

    -
    • -
  • -

    audioDescription (boolean|undefined): If true, the track contains audio -indications helping to understand what’s on the screen. Mostly useful for -the visually impaired, this property is generally only relevant for audio -tracks.

    -
    • -
  • -

    closedCaption (boolean|undefined): If true, that text track contains -supplementary text cues about the audio content. Mostly useful for the hard -of hearing, this property is generally only relevant for text tracks -helping to understand what’s on the screen. Mostly useful for the visually -impaired, this property is generally only relevant for audio tracks.

    -
    • -
  • -

    representations (Array.<Object>): The different available qualities for -this track. Will be described below.

    -
    • -
-

-

The representation object

-

The representation object will describe the different qualities for a given -track (or adaptation). It will also contains logic to fetch segments -corresponding to that quality. The representation object is very similar to the -Representation element in a DASH MPD.

-

As usual, let’s look into an example.

-
{
-  bitrate: 5000000, // bitrate of the quality, in bits per seconds
-  mimeType: "video/mp4",
-  codecs: "avc1.64001f",
-  width: 1280, // default width of the quality, in pixels.
-               // Mostly relevant for video tracks
-  height: 720, // default height of the quality, in pixels.
-               // Mostly relevant for video tracks
-  index: { // declaration of all the linked segments as well as methods to
-           // retrieve them
-    loadInitSegment(callbacks) { /* ... */  },
-    loadSegment(segment, callbacks) { /* ... */,
-    segments: [ /* ... */ ]
-  }
-}
-
-

For audio tracks, it can looks like:

-
{
-  bitrate: 200000,
-  mimeType: "audio/mp4",
-  codecs: "mp4a.40.5",
-  index: {
-    loadInitSegment(callbacks) { /* ... */  },
-    loadSegment(segment, callbacks) { /* ... */,
-    segments: [ /* ... */ ]
-  }
-}
-
-

At last, an example for text tracks (here ttml in an mp4 container):

-
{
-  bitrate: 3000, // bitrate of the quality, in bits per seconds
-  mimeType: "application/mp4",
-  codecs: "stpp",
-  index: {
-    loadInitSegment(callbacks) { /* ... */  },
-    loadSegment(segment, callbacks) { /* ... */,
-    segments: [ /* ... */ ]
-  }
-}
-
-

We’ll now explain what each property is for, before going deeper into the -index attribute, which allows the RxPlayer to fetch the media segments.

-

-

properties

-
    -
  • -

    bitrate (number): The bitrate the quality is in, in bits per seconds. For -example, a bitrate of 5000000 (5.10^6 == 5 MegaBit) would indicate that each -second of the content does on average a size of 5 MegaBit.

    -
    • -
  • -

    mimeType (string): As its name suggests, this is the appropriate mime-type -for the media. Generally, it is either:

    -
      -
    • "video/mp4" or "video/webm" for a video content (depending on the -container)
      • -
    • "audio/mp4" or "audio/webm" for an audio content (depending on the -container)
      • -
    • "application/mp4" or "text/plain" for a text content (depending on -the container / the absence of container)
      • -
    -
    • -
  • -

    codecs (string): The codec necessary to be able to play the content. The -syntax here is taken from the RFC6381.

    -
    • -
  • -

    width (number|undefined): When relevant (mostly video contents), the width -of the media, in pixels

    -
    • -
  • -

    height (number|undefined): When relevant (mostly video contents), the -height of the media, in pixels

    -
    • -
  • -

    index (object): Object allowing the RxPlayer to know the list of segments -as well as to fetch them. Described in the next chapter.

    -
    • -
-

-

the index object

-

As just seen, the index object is a property of a given representation.

-

it contains itself three properties:

-
    -
  • -

    segments (Array.<Object>): the list of every available media segments for -that representation. Does not include the initialization segment.

    -

    Do not include in this Array the segments that are not downloaded yet.

    -
    • -
  • -

    loadInitSegment (function): Returns the initialization segment or null -if this notion is not relevant, like for subtitles.

    -
    • -
  • -

    loadSegment (function): Returns a specific media segment.

    -
    • -
-

-

the segments array

-

Let’s start by the first one, segments. segments is an array of objects, -each object describing a single segment of media data. Each object has the -following properties:

-
    -
  • time (number): starting position of the segment, in seconds
    • -
  • duration (number): duration of the segment, in seconds
    • -
  • timestampOffset (number|undefined): optional time offset to add to the -segment’s internal time in seconds to convert its media time to its -presentation time, in seconds. -If you don’t know what it is, you will most likely not need it.
    • -
-

Let’s see a simple example with four segments of 2 seconds:

-
[
-  {
-    time: 0,
-    duration: 2
-  },
-  {
-    time: 2,
-    duration: 2
-  },
-  {
-    time: 4,
-    duration: 2
-  },
-  {
-    time: 6,
-    duration: 2
-  }
-]
-
-

-

the loadInitSegment callback

-

The loadInitSegment callback allows the RxPlayer to request the initialization -segment of this representation.

-

Most audio and video representation have an initialization segment which allows -to obtain information about the representation’s data without containing data in -itself. -For text representations, where it is most likely not needed, this callback can -emit null instead of the segment.

-

This callback is given a single argument, which is an object containing -callbacks the function should call either when it has fetched the content or -when it failed on error. There is two callbacks in that object:

-
    -
  • -

    resolve: allows loadInitSegment to communicate the initialization segment -in an ArrayBuffer form. Can call resolve with null if no initialization -segment is available for that representation.

    -
    • -
  • -

    reject: allows loadInitSegment to communicate an error which made the -fetching of the initialization segment impossible.

    -
    • -
-

The loadInitSegment callback can also returns a function which will be called -if the caller want to abort the fetch operation.

-

Here is an example of how a loadInitSegment function can look like:

-
async function loadInitSegment(callbacks) {
-  try {
-    const initSegment = await getStoredInitSegmentForTheCurrentRepresentation();
-    callbacks.resolve(initSegment);
-  } catch (e) {
-    callbacks.reject(e);
-  }
-
-  // Note: in this example, there is no mean to abort the operation, as a result
-  // we do not return a function here
-
-  // // Here is how it would look like if we could:
-  // return function abort() {
-  //   abortStoredInitSegmentRequest();
-  // }
-}
-
-

-

the loadSegment callback

-

The loadSegment callback is the callback called by the RxPlayer when it wants -any segment in the content.

-

Note that the segment data returned by loadSegment should contain all the data -and metadata necessary to play them on the browser. Downloaded DASH segments - -for example - are generally sufficient but segments linked to Smooth contents -should be updated before being returned by loadSegment.

-

This callback is very similar to loadInitSegment with two differences:

-
    -
  • -

    it receives two arguments:

    -
      -
    1. The first being the segment object (from the segments array) of the -segment we want to recuperate. You can generally discriminate which -segment we want from the time property of the given segment, which -should be unique for that representation.
      2. -
    2. The second being the callbacks object, which has the exact same form -than the one in loadInitSegment (two properties resolve and -reject).
      3. -
    -
    • -
  • -

    it cannot return null. It has to return an ArrayBuffer corresponding to -the wanted segment.

    -
    • -
-

Here is an example of how a loadSegment function can look like:

-
async function loadSegment(segment, callbacks) {
-  try {
-    const segmentData = await getStoredSegment(segment);
-    callbacks.resolve(segmentData);
-  } catch (e) {
-    callbacks.reject(e);
-  }
-
-  // Note: in this example, there is no mean to abort the operation, as a result
-  // we do not return a function here
-
-  // // Here is how it would look like if we could:
-  // return function abort() {
-  //   abortStoredSegmentRequest();
-  // }
-}
-
-

-

About DRMs

-

Content with DRMs should be supported as long as the encryption information is -specified in the corresponding containers (e.g. in PSSH boxes for mp4 and other -ISOBMFF containers).

-

We also look into adding supplementary encryption information into the local -manifest format, but this is not available for now.

-

-

Difference with the 0.1 format

-

The previous 0.1 version of the local Manifest is now obsolete and is not -compatible with the new versions of the RxPlayer. -Its documentation can be found here.

-

If you were relying on this version before and would like to switch the the -0.2 version, to be able to play it on newer versions of the RxPlayer, here -is the exhaustive list of what changed:

-
    -
  • -

    a minimumPosition has been added to the “period object”

    -
    • -
  • -

    a maximumPosition has been added to the “period object”

    -
    • -
  • -

    the duration property of the “period object” has been removed

    -
    • -
  • -

    the start property from a “period object” is now expressed in seconds -instead of in milliseconds.

    -
    • -
  • -

    the end property from a “period object” is now expressed in seconds -instead of in milliseconds.

    -
    • -
  • -

    the time property from a segment in the “segments array” is now expressed -in seconds instead of in milliseconds.

    -
    • -
  • -

    the duration property from a segment in the “segments array” is now -expressed in seconds instead of in milliseconds.

    -
    • -
  • -

    the timestampOffset property from a segment in the “segments array” is now -expressed in seconds. In the 0.1 version the unit of time was unclear.

- -
🏠Home🗎Page List↑Top

-

Local Manifest format version 0.1

-
-

⚠️ The 0.1 version of the local Manifest format is an old version which -is not properly understood by the RxPlayer anymore.

-

The last version of this specification can be found here.

-
-

-

Preamble

-

The RxPlayer is also able to load downloaded DASH, Smooth, MetaPlaylist or even -HLS (CMAF-based) contents, whether it is for offline playback or just for an -online seamless playback without buffering.

-

This documentation page will be about how to load already downloaded contents. -We suppose the content is already downloaded and that you just want to play it -through the RxPlayer.

-

However, a tool to download DASH/Smooth/MetaPlaylist contents compatible to this -API is under way.

-

-

Overview

-

To play contents stored locally, the RxPlayer uses its own Manifest format - the -“local manifest” which is close in semantics to DASH’s own Manifest file, the -MPD.

-

This new Manifest format will be the only element you will need to generate on -your side to play stored contents. As such, this what most of this documentation -page is about.

-

Note that the wanted content does not need to be completely downloaded before -creating this local manifest. Playback can even begin while the content is -still downloading.

-

You will just need to:

-
    -
  1. indicate that this is a “local” content by setting the transport option -in loadVideo to "local"
    2. -
  2. As the generated Manifest object most likely won’t be available through an -URL but directly as a JavaScript object, you will need to communicate it -through the manifestLoader property in the transportOptions loadVideo -option.
    3. -
-

Here is an example:

-
rxPlayer.loadVideo({
-  transport: "local",
-  transportOptions: {
-    // Note: `_url` here will be `undefined`
-    manifestLoader(_url, callbacks) {
-      // where `localManifest` is the local Manifest in object form
-      callbacks.resolve({ data: localManifest });
-    }
-  }
-  // ...
-});
-
-

More infos on the manifestLoader can be found -here.

-

-

How to import this feature

-

The "LOCAL_MANIFEST" feature is not included in the default RxPlayer build.

-

There’s two way you can import it, depending on if you’re relying on the minimal -version or if you prefer to make use of environment variables and build the -player manually.

-

Through the minimal version of the RxPlayer

-

If you’re using the “minimal” version of the RxPlayer (through the -"rx-player/minimal" import), you will need to import the LOCAL_MANIFEST -experimental feature:

-
import RxPlayer from "rx-player/minimal";
-import { LOCAL_MANIFEST } from "rx-player/experimental/features";
-
-RxPlayer.addFeatures([LOCAL_MANIFEST]);
-
-

Through environment variables

-

If you don’t want to go the minimal version’s route and you have no problem with -building yourself a new version of the RxPlayer, you can make use of environment -variables to activate it.

-

This can be done through the RXP_LOCAL_MANIFEST environment variable, which -you have to set to true:

-
RXP_LOCAL_MANIFEST=true npm run build:min
-
-

More information about any of that can be found in the minimal player -documentation.

-

-

The Manifest format

-

As explained in the overview, offline playback by the RxPlayer mainly rely on a -specific sort of manifest, called the “local manifest”.

-

It is not the task of the RxPlayer to download and store the content here (a -tool to do just that is on its way), this page only explains how to play a -stored content once it has been stored.

-

The local manifest looks like a DASH MPD in its structure and as such is very -hierarchical.

-

It has the following structure:

-
manifest Object
-  ...manifest properties
-  period Object
-    ...period properties
-    adaptation Object
-      ...adaptation properties
-      representation Object
-        ...representation properties
-
-

We will go progressively from the elements higher in the hierarchy (the manifest -object) to the lower ones (the representation Object).

-

-

The manifest Object

-

The manifest object describes information about the whole local content:

-
    -
  • its duration
    • -
  • whether it is still downloading or if its completely available
    • -
  • the different “parts” (or “periods”) the content is divided in
    • -
-

First, let’s go into an example, before describing what each property is for:

-
{
-  type: "local", // always set to "local"
-  version: "0.1", // version number, in a MAJOR.MINOR form
-  duration: 60000, // duration of the whole content, in ms
-  isFinished: true, // if `false`, the content is still downloading
-  periods: [ // different "periods" in the content - see below
-    // ...
-  ],
-}
-
-

As you can see, it is a simple JavaScript object with few properties we’re going -to dive into just now.

-

-

properties

-

Here is the description about all the properties encountered in a local manifest -object:

-
    -
  • -

    type (string): Must be set to "local". This property indicates to the -RxPlayer that the current content is a local manifest.

    -
    • -
  • -

    version (string): Version number, in a MAJOR.MINOR form. -The present documentation is for the "0.1" version.

    -

    A parser for a version with the a given MAJOR version should be able to -parse and play contents for any of the corresponding MINOR versions.

    -

    The exception is the 0 MAJOR version (i.e. experimental versions). -A parser for a version with that major (let’s say 0.1) might be unable to -parse local Manifests of another version (e.g. 0.2).

    -
    • -
  • -

    duration (number): duration of the whole content, in milliseconds. This -means the difference between the absolute maximum position and the absolute -minimum position.

    -
    • -
  • -

    isFinished (boolean): true indicates that the content has been -completely downloaded and can now be played as a whole. false indicates -that the whole content is not available yet and that the RxPlayer may have -to refresh the local manifest while playing (to get the new data).

    -
    • -
  • -

    periods (Array.<Object>): The different “periods” available in the -content. We will explain what a “period” is in the following chapter.

    -
    • -
  • -

    expired (Promise.<undefined>|undefined): Optional Promise which should -resolve when a newer local manifest is available.

    -

    This is for example useful when playing a content which is still -downloading. Here expired could resolve once a new segment is available, -the RxPlayer would then request the new local manifest (through the same API -than for the initial request, e.g. through the manifestLoader property -indicated in loadVideo) and would obtain a new local manifest with this -new segment included and a new expired property set. -This can go on until the content is completely downloaded at which time -expired can be set to undefined or just omitted from the last local -manifest.

    -
    • -
-

-

The period object

-

As seen in the previous chapter, the local manifest contains a periods -property. The concept of period comes from DASH and allow to separate a content -into multiple sub-parts, each with their own configurations.

-

For example, you could have in the same content a TV Show in german followed by -an american film, each with its own language choices and qualities.

-

If you don’t need that kind of granularity, you can just create a single period -for your local manifest.

-

Here’s an example of a period object:

-
{
-  start: 10000, // starting position in the whole content, in ms
-  end: 20000, // ending position, in ms
-  adaptations: [ // available tracks for this period
-    // ***
-  ]
-}
-
-

In the context of a local manifest with multiple periods, here is how it can -look like:

-
{
-  type: "local",
-  version: "0.1",
-  duration: 60000,
-  isFinished: true,
-  periods: [ // Here we have 3 consecutive periods:
-    {
-      start: 0,
-      end: 10000,
-      adaptations: [ /* ... */ ]
-    },
-    {
-      start: 10000,
-      end: 30000,
-      adaptations: [ /* ... */ ]
-    },
-    {
-      start: 30000,
-      end: 60000,
-      adaptations: [ /* ... */ ]
-    },
-  ],
-}
-
-

-

properties

-

The following properties are found in a period object:

-
    -
  • -

    start (number): The position in milliseconds at which the period starts.

    -
    • -
  • -

    end (number): The position in milliseconds at which the period ends.

    -
    • -
  • -

    adaptations (Array.<Object>): The different tracks available. See below -for more information.

    -
    • -
-

-

the adaptation object

-

An adaptation is roughly a “track” of the content. It can for the moment be one -of those three types:

-
    -
  • “audio”
    • -
  • “video”
    • -
  • “text” (subtitles)
    • -
-

The form of the adaptation object depends on the type of track. Let’s just start -with a simple video track example:

-
{
-  type: "video",
-  language: "eng", // optional language code
-  representations: [ // describes the different available qualities
-    // ...
-  ]
-}
-
-

Let’s continue with an audio track example:

-
{
-  type: "audio",
-  language: "fra", // language code for this audio track
-  audioDescription: false, // if `true`, that audio track is a track adapted for
-                           // the visually impaired
-  representations: [ /* ... */ ]
-}
-
-

We’ll finish with a text track example:

-
{
-  type: "text",
-  language: "fra", // language code for this audio track
-  closedCaption: false, // if `true`, that text track contains supplementary
-                        // cues about the audio content (generally used for the
-                        // hard of hearing)
-  representations: [ /* ... */ ]
-}
-
-

Here how it looks when adaptations are integrated in a given period:

-
{
-  start: 0,
-  end: 10000,
-  adaptations: [
-    {
-      type: "video",
-      representations: [ /* ... */ ],
-    },
-    {
-      type: "audio",
-      language: "eng",
-      audioDescription: false,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "audio",
-      language: "fra",
-      audioDescription: false,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "audio",
-      language: "fra",
-      audioDescription: true,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "text",
-      language: "fra",
-      closedCaption: false,
-      representations: [ /* ... */ ]
-    },
-    {
-      type: "text",
-      language: "fra",
-      closedCaption: true,
-      representations: [ /* ... */ ]
-    }
-  ]
-},
-
-

Let’s now describes precizely every properties encountered here.

-

-

properties

-

The following properties are found in an adaptation object:

-
    -
  • -

    type (string): The “type” of the current adaptation. Can be one of three -strings:

    -
      -
    1. audio
      2. -
    2. video
      3. -
    3. text -The two first ones are straightforward to understand, the third one -designates subtitles.
      4. -
    -
    • -
  • -

    language (string|undefined): When relevant, this string allows to define -the language code for the language the track is in. This is mostly useful -for audio and text adaptations but can also be defined for video tracks.

    -
    • -
  • -

    audioDescription (boolean|undefined): If true, the track contains audio -indications helping to understand what’s on the screen. Mostly useful for -the visually impaired, this property is generally only relevant for audio -tracks.

    -
    • -
  • -

    closedCaption (boolean|undefined): If true, that text track contains -supplementary text cues about the audio content. Mostly useful for the hard -of hearing, this property is generally only relevant for text tracks -helping to understand what’s on the screen. Mostly useful for the visually -impaired, this property is generally only relevant for audio tracks.

    -
    • -
  • -

    representations (Array.<Object>): The different available qualities for -this track. Will be described below.

    -
    • -
-

-

The representation object

-

The representation object will describe the different qualities for a given -track (or adaptation). It will also contains logic to fetch segments -corresponding to that quality. The representation object is very similar to the -Representation element in a DASH MPD.

-

As usual, let’s look into an example.

-
{
-  bitrate: 5000000, // bitrate of the quality, in bits per seconds
-  mimeType: "video/mp4",
-  codecs: "avc1.64001f",
-  width: 1280, // default width of the quality, in pixels.
-               // Mostly relevant for video tracks
-  height: 720, // default height of the quality, in pixels.
-               // Mostly relevant for video tracks
-  index: { // declaration of all the linked segments as well as methods to
-           // retrieve them
-    loadInitSegment(callbacks) { /* ... */  },
-    loadSegment(segment, callbacks) { /* ... */,
-    segments: [ /* ... */ ]
-  }
-}
-
-

For audio tracks, it can looks like:

-
{
-  bitrate: 200000,
-  mimeType: "audio/mp4",
-  codecs: "mp4a.40.5",
-  index: {
-    loadInitSegment(callbacks) { /* ... */  },
-    loadSegment(segment, callbacks) { /* ... */,
-    segments: [ /* ... */ ]
-  }
-}
-
-

At last, an example for text tracks (here ttml in an mp4 container):

-
{
-  bitrate: 3000, // bitrate of the quality, in bits per seconds
-  mimeType: "application/mp4",
-  codecs: "stpp",
-  index: {
-    loadInitSegment(callbacks) { /* ... */  },
-    loadSegment(segment, callbacks) { /* ... */,
-    segments: [ /* ... */ ]
-  }
-}
-
-

We’ll now explain what each property is for, before going deeper into the -index attribute, which allows the RxPlayer to fetch the media segments.

-

-

properties

-
    -
  • -

    bitrate (number): The bitrate the quality is in, in bits per seconds. For -example, a bitrate of 5000000 (5.10^6 == 5 MegaBit) would indicate that each -second of the content does on average a size of 5 MegaBit.

    -
    • -
  • -

    mimeType (string): As its name suggests, this is the appropriate mime-type -for the media. Generally, it is either:

    -
      -
    • "video/mp4" or "video/webm" for a video content (depending on the -container)
      • -
    • "audio/mp4" or "audio/webm" for an audio content (depending on the -container)
      • -
    • "application/mp4" or "text/plain" for a text content (depending on -the container / the absence of container)
      • -
    -
    • -
  • -

    codecs (string): The codec necessary to be able to play the content. The -syntax here is taken from the RFC6381.

    -
    • -
  • -

    width (number|undefined): When relevant (mostly video contents), the width -of the media, in pixels

    -
    • -
  • -

    height (number|undefined): When relevant (mostly video contents), the -height of the media, in pixels

    -
    • -
  • -

    index (object): Object allowing the RxPlayer to know the list of segments -as well as to fetch them. Described in the next chapter.

    -
    • -
-

-

the index object

-

As just seen, the index object is a property of a given representation.

-

it contains itself three properties:

-
    -
  • -

    segments (Array.<Object>): the list of every available media segments for -that representation. Does not include the initialization segment.

    -

    Do not include in this Array the segments that are not downloaded yet.

    -
    • -
  • -

    loadInitSegment (function): Returns the initialization segment or null -if this notion is not relevant, like for subtitles.

    -
    • -
  • -

    loadSegment (function): Returns a specific media segment.

    -
    • -
-

-

the segments array

-

Let’s start by the first one, segments. segments is an array of objects, -each object describing a single segment of media data. Each object has the -following properties:

-
    -
  • time (number): starting position of the segment, in milliseconds
    • -
  • duration (number): duration of the segment, in milliseconds
    • -
  • timestampOffset (number|undefined): optional time offset to add to the -segment’s internal time to convert its media time to its presentation time, -in milliseconds. -If you don’t know what it is, you will most likely not need it.
    • -
-

Let’s see a simple example with four segments of 2 seconds:

-
[
-  {
-    time: 0,
-    duration: 2000
-  },
-  {
-    time: 2000,
-    duration: 2000
-  },
-  {
-    time: 4000,
-    duration: 2000
-  },
-  {
-    time: 6000,
-    duration: 2000
-  }
-]
-
-

-

the loadInitSegment callback

-

The loadInitSegment callback allows the RxPlayer to request the initialization -segment of this representation.

-

Most audio and video representation have an initialization segment which allows -to obtain information about the representation’s data without containing data in -itself. -For text representations, where it is most likely not needed, this callback can -emit null instead of the segment.

-

This callback is given a single argument, which is an object containing -callbacks the function should call either when it has fetched the content or -when it failed on error. There is two callbacks in that object:

-
    -
  • -

    resolve: allows loadInitSegment to communicate the initialization segment -in an ArrayBuffer form. Can call resolve with null if no initialization -segment is available for that representation.

    -
    • -
  • -

    reject: allows loadInitSegment to communicate an error which made the -fetching of the initialization segment impossible.

    -
    • -
-

The loadInitSegment callback can also returns a function which will be called -if the caller want to abort the fetch operation.

-

Here is an example of how a loadInitSegment function can look like:

-
async function loadInitSegment(callbacks) {
-  try {
-    const initSegment = await getStoredInitSegmentForTheCurrentRepresentation();
-    callbacks.resolve(initSegment);
-  } catch (e) {
-    callbacks.reject(e);
-  }
-
-  // Note: in this example, there is no mean to abort the operation, as a result
-  // we do not return a function here
-
-  // // Here is how it would look like if we could:
-  // return function abort() {
-  //   abortStoredInitSegmentRequest();
-  // }
-}
-
-

-

the loadSegment callback

-

The loadSegment callback is the callback called by the RxPlayer when it wants -any segment in the content.

-

Note that the segment data returned by loadSegment should contain all the data -and metadata necessary to play them on the browser. Downloaded DASH segments - -for example - are generally sufficient but segments linked to Smooth contents -should be updated before being returned by loadSegment.

-

This callback is very similar to loadInitSegment with two differences:

-
    -
  • -

    it receives two arguments:

    -
      -
    1. The first being the segment object (from the segments array) of the -segment we want to recuperate. You can generally discriminate which -segment we want from the time property of the given segment, which -should be unique for that representation.
      2. -
    2. The second being the callbacks object, which has the exact same form -than the one in loadInitSegment (two properties resolve and -reject).
      3. -
    -
    • -
  • -

    it cannot return null. It has to return an ArrayBuffer corresponding to -the wanted segment.

    -
    • -
-

Here is an example of how a loadSegment function can look like:

-
async function loadSegment(segment, callbacks) {
-  try {
-    const segmentData = await getStoredSegment(segment);
-    callbacks.resolve(segmentData);
-  } catch (e) {
-    callbacks.reject(e);
-  }
-
-  // Note: in this example, there is no mean to abort the operation, as a result
-  // we do not return a function here
-
-  // // Here is how it would look like if we could:
-  // return function abort() {
-  //   abortStoredSegmentRequest();
-  // }
-}
-
-

-

About DRMs

-

Content with DRMs should be supported as long as the encryption information is -specified in the corresponding containers (e.g. in PSSH boxes for mp4 and other -ISOBMFF containers).

-

We also look into adding supplementary encryption information into the local -manifest format, but this is not available for now.

Playing Low-Latency contents

-

-

Overview

-

The RxPlayer can play DASH contents specifically crafted to be played with a -low latency (read close to the live edge) through a technology called something -along the lines of “Chunked-encoded CMAF and Chunked transfer encoding”.

-

Such contents are backward-compatible DASH contents (meaning they can be played -in a regular non-low-latency way) which serves CMAF segment with an HTTP 1.1 -transfer mechanism called “Chunked transfer encoding”.

-

To vulgarize, such segments are divided into multiple chunks which can be -requested while the whole segment is still being encoded - through Chunked -transfer encoding HTTP requests.

-

If you want more information on this technology, the best for us is probably to -redirect you to the multiple resources you can probably find with your favorite -search engine!

-

-

How to play a low latency content

-

-

lowLatencyMode option

-

To play a low-latency DASH content with - well - a low latency, you will need -to set the lowLatencyMode loadVideo option.

-
rxPlayer.loadVideo({
-  url: "https://www.example.com/low-latency-content.mpd",
-  transport: "dash",
-  lowLatencyMode: true,
-})
-
-

When set, this option will perform multiple optimizations specific to -low-latency contents. For live contents:

-
    -
  • -

    it will by default play much closer to the live edge

    -
    • -
  • -

    it will begin to play faster and seek in non-buffered parts faster

    -
    • -
  • -

    it will do safer choices when choosing the right video / audio quality (to -avoid the higher chances of rebuffering)

    -
    • -
  • -

    the delay we use when retrying a failed segment or manifest request will be -lower

    -
    • -
  • -

    and multiple other minor optimizations

    -
    • -
-

Note that you can also set the lowLatencyMode mode for VoD (non-live) -contents. -In that case, the main advantage would be to be able to play and seek faster as -long as the content is compatible (again, with CMAF and Chunked Transfer -Encoding).

-

-

Playing even closer to the live edge!

-

By default, we set a distance of 3.5 seconds relative to the live edge when we -start a low latency content.

-

We found that value to be just at the right boundary between rebuffering risks, -and delay to the live edge.

-

However, you can still provide a lower distance through the startAt -loadVideo option (documented here):

-
rxPlayer.loadVideo({
-  url: "https://www.example.com/content.mpd",
-  transport: "dash",
-  lowLatencyMode: true,
-  startAt: { fromLastPosition: 2 }, // Play 2 seconds from the live edge instead
-                                    // (beware of much more frequent rebuffering
-                                    // risks)
-})
-
-

-

-

Note about time synchronization

-

In most cases, DASH low-latency contents rely on time synchronization between -the server and the client without providing a synchronization mechanism.

-

This means that, on poorly configurated client (with bad clock settings), you -could lose latency or worse: obtain playback issues.

-

To work around that problem, the RxPlayer allows you to provide a -synchronization mechanism to loadVideo. This is done through the -serverSyncInfos transportOptions. Which itself is a loadVideo option.

-

TL;DR You can look at the API -documentation for a quick -explanation of what to put in it.

-
-

Here how it works:

-

Imagine you have an URL allowing you to know the UTC time on the server’s side. -Let’s call it serverTimeURL.

-

Now you can have the server’s time at a particular point in time (!). The -problem is that time continously changes: a time synchronization mechanism will -have to be aware of how much time passed since the last request to obtain that -time.

-

We could asks for the client’s timestamp - obtained thanks to the Date.now() -API - at the time of the request. -This would allow us to know how much time have passed since that event by -calling Date.now() again in the future and calculating the difference. -The problem however is that Date.now() will instantly change if the user -updates its system clock. If that happens, we will lose the ability to know how -much time has elapsed since the request.

-

To workaround this issue, we can use instead performance.now(), which does not -rely on the system’s clock. -However, we are still left with two other issues:

-
    -
  1. -

    performance.now() comparisons are useful only if both values were -obtained in the same JS worker. -So we have to make sure each performance.now() call is done in the same -worker.

    -
    2. -
  2. -

    performance.now() doesn’t integrate the notion of leap seconds whereas -unix time (the server’s time) does. This could mean small time -de-synchronization when leap seconds are added or substracted.

    -
    3. -
-

We however consider those last two problems minor when compared to -Date.now()'s problem (which is the fact that it “breaks” if the system clock -is updated). If you would prefer to provide Date.now() anyway, you can open -an issue and we will think about a possible implementation.

-

So we now have two values:

-
    -
  • serverTimestamp (number): Unix timestamp of the server at a given -point in time.
    • -
  • clientTime (number): Value of the performance.now() API at the -time the serverTimestamp value was true. Please note that if your page -contains multiple worker, the performance.now() call should be done on -the same worker than the one in which loadVideo is called.
    • -
-

Those two values can be combined in the serverSyncInfos option like this:

-
const timeResponse = await fetch(serverTimeURL);
-const serverTimestamp = await timeResponse.text();
-const clientTime = performance.now();
-const serverSyncInfos = { serverTimestamp, clientTime };
-rxPlayer.loadVideo({
-  // ...
-  transportOptions: { serverSyncInfos }
-})
-
-

-

Note about rebuffering and other delay-creating situations

-

When playing in low latency mode, it is still possible to rebuffer or pause the -content, which could lead the user to being far from the live edge.

-

As several applications could want several workaround to that possible issue -(like updating the speed, seeking or just signaling the delay to the user), we -choose to let that happen by default with the RxPlayer.

-

As an example, ou demo page choose the following strategy for now:

-
    -
  • -

    When falling between 6 to 15 seconds behind the live edge, the playback rate -is updated proportionally to our delay until we reach 3 seconds behind the -live edge.

    -
    • -
  • -

    When falling to 15 seconds behind the live edge or more, we will simply seek -to 3 seconds behind the live edge.

    -
    • -
  • -

    When seeking manually or pausing, this logic is disabled (with the -possibility to re-enable it).

    -
    • -
-

The live edge is obtainable through the rxPlayer.getMaximumPosition() API, -the current position thanks to the rxPlayer.getPosition() API. The distance to -the live edge is thus easily computable:

-
rxPlayer.getMaximumPosition() - rxPlayer.getPosition()

Manifest Object

-

-

-

Overview

-

A Manifest Object and its sub-parts are data structures returned by multiple -APIs of the player.

-

Its data represents the corresponding streaming protocol’s -Manifest equivalent (MPD for DASH, Manifest for -Microsoft Smooth Streaming etc.).

-

Basically, the structure of a Manifest file has the following hierarchy:

-
Manifest Object
-  ...Manifest data and methods
-  Period Object
-    ...Period properties
-    Adaptation Object
-      ...Adaptation data and methods
-      Representation Object
-        ...Representation data and methods
-        RepresentationIndex Object
-          ...RepresentationIndex data and methods
-            SegmentObject
-            ...SegmentObject data
-
-

Due to this highly hierachical structure, each level will be described in its -own chapter here.

-

⚠️ Like in the rest of this documentation, any variable or method not -defined here can change without notice.

-

Only use the documented variables and open an issue if you think it’s not -enough.

-

-

-

Structure of a Manifest Object

-

The manifest Object represents the Manifest file of the -content loaded.

-

-

-

properties

-

The manifest Object has the following properties.

-

periods

-

type: Array.<Period>

-

A single Manifest instance can contain multiple Periods, -which are periods of time for which the list of available type of contents -(audio tracks, subtitles, video tracks…) can be different.

-

Such example of Periods could be multiple Programs of a live contents, which can -be each in different languages, for example.

-

The player will switch smoothly across subsequent Periods within playback.

-

Most Streaming technologies (e.g. HLS and Smooth) do not have a “Period” -concept. For those, the Manifest will only have one Period for the whole -content.

-

adaptations

-
-

⚠️ This property is deprecated, it will disappear in the next major -release v4.0.0 (see Deprecated APIs).

-
-

type: Object

-

Adaptation objects for the first Period.

-

Both of those lines have the same effect:

-
console.log(manifest.adaptations);
-console.log(manifest.periods[0].adaptations);
-
-

See the Period chapter for more information on Adaptations.

-

isLive

-

type: Boolean

-

true if the content is a “live” content (e.g. a live TV Channel). -false otherwise.

-

uris

-

type: Array.<string>

-

The list of uris that can be used to refer to the Manifest file.

-

transport

-

type: string

-

The type of transport used. For now, this can only be equal to either dash -or smooth.

-

-

-

Structure of a Period Object

-

A Period is an object describing what to play during a certain time periods.

-

A Manifest can have a single Period, which means that the played content do not -change its characteristics (same languages, same bitrates etc.) or multiple -ones.

-

A good example of a content with multiple Periods would be a live channel -broadcasting multiple foreign films. Each film, being in a different language, -will need to be part of a new Period.

-

-

-

properties

-

id

-

type: string

-

This id should be a string unique to that Period. It serves identifications -purpose, when updating the Manifest for example.

-

start

-

type: Number

-

Start time at which the Period begins in the whole content, in seconds.

-

end

-

type: Number|undefined

-

End time at which the Period ends in the whole content, in seconds.

-

If not set or set to undefined, it means that the end is unknown, in which case -it is the current last content of the current Manifest.

-

adaptations

-

type: Object

-

The Adaptations (tracks if you want) for the current -content, per-type (audio/video/text/image).

-

See the Adaptation chapter for more info about an Adaptation’s -structure.

-

The Adaptation object can contain any of the following keys:

-
    -
  • audio (Array.<Adaptation>): The audio Adaptation(s) available.
    • -
  • video (Array.<Adaptation>): The video Adaptation(s) available.
    • -
  • text (Array.<Adaptation>): The text Adaptation(s) available.
    • -
  • image (Array.<Adaptation>): The image Adaptation(s) available.
    • -
-

-

-

Structure of an Adaptation Object

-

An Adaptation is a set of streams representing the -exact same contents in multiple forms (different sizes, different bitrates…). -Concretely, a frequent usecase is to have a single video Adaptation and multiple -audio ones, one for each language available.

-

As such, it is also often called in the API a track.

-

-

-

properties

-

id

-

type: string

-

This id should be a string unique to that Adaptation. It serves -identifications purpose, when updating the Manifest for example.

-

type

-

type: string

-

The type of the Adaptation. The possible types are:

-
    -
  • "video"
    • -
  • "audio"
    • -
  • "text"
    • -
  • "image"
    • -
-

language

-

type: string|undefined

-

The language of the Adaptation. This is particularly useful for audio and text -Adaptations.

-

Note that this property is not always present in an Adaptation.

-

normalizedLanguage

-

type: string|undefined

-

An attempt to translate the language of the Adaptation into an ISO 639-3 code. -If the translation attempt fails (no corresponding ISO 639-3 language code is -found), it will equal the value of language

-

Note that this property is not always present in an Adaptation.

-

isAudioDescription

-

type: Boolean|undefined

-

This property only makes sense for audio Adaptations. In this case, if true -it means that the audio track has added commentaries for the visually impaired.

-

isClosedCaption

-

type: Boolean|undefined

-

This property only makes sense for text Adaptations. In this case, if true -it means that the text track has added hints for the hard of hearing.

-

representations

-

type: Array.<Representation>

-

The Represesentations for this Adaptation.

-

See the Representation chapter for more info about a -Representation’s structure.

-

-

-

methods

-

getAvailableBitrates

-

return value: Array.<Number>

-

Returns every bitrates available for this Adaptation.

A Representation is an -Adaptation encoded in a certain way. It is defined by -multiple values (a codec, a bitrate). Only some of them are documented here (as -stated before, open an issue if you would like to access other properties).

-

-

-

properties

-

id

-

type: string

-

This id should be a string unique to that Representation.

-

bitrate

-

type: Number

-

The bitrate of the Representation.

-

codec

-

type: string|undefined

-

The codec of the Representation.

-

decipherable

-

type: boolean|undefined

-

Whether we are able to decrypt this Representation / unable to decrypt it or -if we don’t know yet:

-
    -
  • if true, it means that we know we were able to decrypt this -Representation in the current content.
    • -
  • if false, it means that we know we were unable to decrypt this -Representation
    • -
  • if undefined there is no certainty on this matter
    • -
-

height

-

type: Number|undefined

-

This property makes the most sense for video Representations. -It defines the height of the video, in pixels.

-

width

-

type: Number|undefined

-

This property makes the most sense for video Representations. -It defines the width of the video, in pixels.

-

index

-

type: RepresentationIndex

-

The represesentation index for this Representation.

-

See the RepresentationIndex chapter for more info about -a RepresentationIndex’s structure.

-

frameRate

-

type: string|undefined

-

The represesentation frame rate for this Representation. It defines either the -number of frames per second as an integer (24), or as a ratio (24000 / 1000).

-

-

-

Structure of a RepresentationIndex Object

-

A RepresentationIndex is an uniform way of declaring the segment index in any -Manifest.

-

That’s the part that calculates which segments will be needed. Because the index -can be different depending on the type of contents/transport most interactions -here are done through few methods which hide the complexity underneath.

-

-

-

methods

-

getSegments

-

arguments:

-
    -
  • -

    up (Number): The position, in seconds from which you want to get the -segment.

    -
    • -
  • -

    duration (Number): The duration in seconds from the asked position

    -
    • -
-

return value: Array.<Segment>

-

Returns the needed segments as defined by the current Manifest during an asked -timeframe.

-

See the Segment chapter for more info about a Segment’s structure.

-

-

-

Structure of a Segment Object

-

A Segment object defines a segment, as generated by the RepresentationIndex.

-

Those segments can have multiple useful properties which for the most part are -described here.

-

-

-

properties

-

id

-

type: string

-

This id should be a string unique to that segment.

-

timescale

-

type: Number

-

The timescale in which the duration and time are expressed.

-

Basically, divide any of those by the timescale to obtain seconds.

-

duration

-

type: Number|undefined

-

The duration, timescaled, of the Segments in s.

-

time

-

type: Number

-

The start time, timescaled, of the Segments in s.

-

isInit

-

type: Boolean|undefined

-

If true, the segment concerned is an init segment.

-

range

-

type: Array.<Number>|null|undefined

-

If defined, it means that the segment is defined in a certain byte range -remotely. In this case, the array contains two elements, the start byte and the -end byte.

-

indexRange

-

type: Array.<Number>|null|undefined

-

If defined, it means that a segment index is defined in a certain byte range -remotely. In this case, the array contains two elements, the start byte and the -end byte.

-

number

-

type: Number|undefined

-

The number of the segment (if numbered), useful with certain types of index.

MediaCapabilitiesProber

-

-

Overview

-

The MediaCapabilitiesProber is a tool probing what your browser can do, -especially:

-
    -
  • -

    Which DRM system is supported

    -
    • -
  • -

    Check for HDCP support

    -
    • -
  • -

    which codecs are available

    -
    • -
  • -

    Check the color space support

    -
    • -
-

⚠️ This tool is still in an experimental phase, meaning that its API can -change at any new release. This is not because it is not stable (it is actually) -or should not be used in production. This is just because we want to receive -your feedbacks before locking definitely the API.

-

We can for example add supplementary information of even explode the -MediaCapabilitiesProber into several tools to lower the size of the import. -We’re waiting for your feedbacks!

-

-

How to use it

-

As an experimental tool, the MediaCapabilitiesProber won’t be included in a -default RxPlayer build.

-

Instead, it should be imported by adding the RxPlayer through a dependency -trough the npm registry (e.g. by doing something like npm install rx-player) and then specifically importing this tool from -"rx-player/experimental/tools":

-
import { mediaCapabilitiesProber } from "rx-player/experimental/tools";
-
-mediaCapabilitiesProber.getStatusForHDCP("1.1")
-  .then((hdcp11Status) => {
-    if (hdcp11Status === "Supported") {
-      console.log("HDCP 1.1 is supported");
-    }
-  });
-
-

-

Properties

-

-

LogLevel

-

type: string

-

default: "WARNING"

-

The current level of verbosity for this prober logs. Those logs all use the -console.

-

From the less verbose to the most:

-
    -
  • -

    "NONE": no log

    -
    • -
  • -

    "ERROR": unexpected errors (via console.error)

    -
    • -
  • -

    "WARNING": The previous level + minor problems encountered (via -console.warn)

    -
    • -
  • -

    "INFO": The previous levels + noteworthy events (via console.info)

    -
    • -
  • -

    "DEBUG": The previous levels + normal events of the prober (via -console.log)

    -
    • -
-

If the value set to this property is different than those, it will be -automatically set to "NONE".

-

It is set to "WARNING" by default as it allows you to know if you forgot to -set required information on each APIs, if some APIs are missing in your -browser, etc.

-

You might want to set it to "NONE" when in production.

-

Example

-
import { mediaCapabilitiesProber } from "rx-player/experimental/tools";
-mediaCapabilitiesProber.LogLevel = "NONE";
-
-

-

Functions

-

-

getCompatibleDRMConfigurations

-

arguments:

-
    -
  • -

    keySystems (Array.<Object>): An array of key system -configurations. Those objects have the following properties:

    -
      -
    • -

      type (string): Key system string identifying it in the browser. -Always a reverse domain name (e.g. “org.w3.clearkey”).

      -
      • -
    • -

      configuration (Object): Wanted MediaKeySystemConfiguration for this -key system, as defined in the EME w3c -specification.

      -
      • -
    -
    • -
-

return value: Array.<Object>

-

Probe the support of various key sytems and for each compatible ones, returns -the corresponding configuration that will be used.

-

Return value

-

The returned value is an array of object with the same number of elements than -the one given in argument.

-

It indicates the support for each Key System given in argument in the same -order.

-

Due to that, the objects in this array look like the ones given in argument (but -with an added property):

-
    -
  • -

    type (string): Corresponding key system string given in input.

    -
    • -
  • -

    configuration (Object): Corresponding wanted -MediaKeySystemConfiguration given in input.

    -
    • -
  • -

    compatibleConfiguration (undefined|Object):

    -

    if the type and configuration are both compatible with the browser, this -is the corresponding actual MediaKeySystemConfiguration that will be -effectively used. -It will often correspond to a subset of the inputted configuration -object (for example, you might have there fewer videoCapabilities that -in the configuration object).

    -

    If the type and/or the configuration are not compatible, this property -will not be defined.

    -
    • -

-
import { mediaCapabilitiesProber } from "rx-player/experimental/tools";

MetaPlaylist v0.1

-

-

Overview

-

The MetaPlaylist is a file allowing to define a content composed of multiple -DASH or Smooth contents played one after another.

-

It allows advanced use cases for an extremely low cost for the server -infrastructure, the main one being creating a linear (live) contents from -multiple non-linear (VOD) ones, without touching the original contents.

-

You can also construct a new non-linear contents as a concatenation of multiple -non-linear contents put one after the other. This method allows for example for -a completely smooth streaming between multiple programs (e.g. when -binge-watching a serie).

-

-

Differences with plain DASH contents

-

The same result could be approximated with some advanced DASH features, but the -MetaPlaylist has several advantages. Some of them are:

-
    -
  • -

    it supports DASH and HSS contents (technically HLS would also be possible) -without modifying the original MPD/Manifest nor segments.

    -
    • -
  • -

    the Manifest/MPD/Playlist corresponding to the original contents can -be lazy-loaded (loaded only when the content will play).

    -

    This is also possible in DASH with a feature called XLinks but it’s not -always doable on the client-side, depending on the other elements present in -that MPD.

    -

    A MetaPlaylist file is much more strict in this regard.

    -

    This is still a work-in-progress.

    -
    • -
  • -

    it’s a format especially intended to be a concatenation of multiple -contents to be played on the web.

    -

    As such, advanced features such as declaring segments before they -should be played or avoiding many customers doing the same manifest -request at the exact same time are much easier to implement.

    -
    • -
  • -

    this file rarely needs to be updated, improving the caching of this -ressource.

    -
    • -
  • -

    its format is very simple and in JSON, which is easy to integrate with -JavaScript codebases. The file can even be very easily generated directly on -the client’s page. This paves the way for contents personalized to a single -customer.

    -
    • -
  • -

    Digital right management is also much more flexible than with a DASH MPD. -For example, different license servers for different contents could be -integrated. This is still a work-in-progress.

    -
    • -
  • -

    the specification is simple, try to allow no interpretation and is strict on -what is permitted.

    -
    • -
  • -

    All its features have been tested on web applications, meaning that you have -the guarantee everything will work on most MSE-compatible browsers, even -IE11.

    -
    • -

-

Structure of a MetaPlaylist

-

A MetaPlaylist file is a simple JSON file.

-

To jump into it right away, let me introduce some examples.

-

For a VOD content:

-
{
-  "type": "MPL",
-  "version": "0.1",
-  "contents": [
-    {
-      "url": "http://url.to.some/DASH/first_content.mpd",
-      "startTime": 0,
-      "endTime": 100.38,
-      "transport": "dash"
-    },
-    {
-      "url": "http://url.to.some/DASH/second_content.Manifest",
-      "startTime": 100.38,
-      "endTime": 372,
-      "transport": "smooth"
-    },
-    {
-      "url": "http://url.to.some/Smooth/third_content.mpd",
-      "startTime": 372,
-      "endTime": 450.787,
-      "transport": "dash"
-    }
-  ]
-}
-
-

For a live content:

-
{
-  "type": "MPL",
-  "version": "0.1",
-  "dynamic": true,
-  "pollInterval": 5,
-  "contents": [
-    {
-      "url": "http://url.to.some/DASH/content.mpd",
-      "startTime": 1545845950.176,
-      "endTime": 1545845985.571,
-      "transport": "dash"
-    },
-    {
-      "url": "http://url.to.some/other/DASH/content.mpd",
-      "startTime": 1545845985.571,
-      "endTime": 1545845998.710,
-      "transport": "dash"
-    },
-    {
-      "url": "http://url.to.some/Smooth/content.Manifest",
-      "startTime": 1545845998.710,
-      "endTime": 1545845117,
-      "transport": "smooth"
-    }
-  ]
-}
-
-

You may already have a basic understanding of it how works. -Let’s define nonetheless every property in that JSON file.

-

-

the header

-

What I call the “header” here is roughly all root properties but “contents”.

-

Here is an exhaustive list of what you should put there:

-
    -
  • -

    type (string): should always be equal to "MPL", for “MetaPlayList”.

    -

    The purpose of this value is to facilitate the checks a player might want to -perform to verify that it is handling a MetaPlaylist file. -The end goal would be for example to improve error reporting for very -frequent mistakes like not providing the URL of the right content.

    -
    • -
  • -

    version (string): version of the MetaPlaylist file. Separated in two parts -by a point (‘.’).

    -

    The first part indicates the major version. If its number is higher than -what the client presently manage, the client should not try to read that -file.

    -

    The last part indicates the minor version: -A new feature or fix have been added but its support is not needed by a -client (a client written for the 1.0 version can be used even for the -1.99 version).

    -

    Please note that there is an exception for 0.x versions, where each minor -versions could have a breaking change (as it is in that case considered an -experimental format).

    -

    At the moment, there is only one version the version "0.1". Thus, this is -what you have to set in your JSON if you integrate this specification.

    -
    • -
  • -

    dynamic (boolean|undefined): If true, the MetaPlaylist file is not -finished, and might need to be updated. If false, the MetaPlaylist could -still need to be updated but its current content indicates a finished -content: A player should end when the end of the last content has been -reached.

    -

    This property is not mandatory and as such can be omitted. By default, it is -considered as not dynamic (so false).

    -
    • -
  • -

    pollInterval (number|undefined): If not set or set to a negative number, -the MetaPlaylist file does not need to be reloaded.

    -

    If set to a positive number, this is the maximum interval in seconds at -which the MetaPlaylist file should be fetched from the server (which means -that the MetaPlaylist could be refreshed more often depending on the current -conditions).

    -

    This should only be defined for dynamic contents.

    -

    This property is not mandatory and as such can be omitted. By default, it is -equivalent to -1 (which means no reload).

    -
    • -
-

-

The contents

-

The contents are all defined as a property called contents at the top level of -our MetaPlaylist file.

-

It is an array of one or multiple objects (an empty contents array is not a -valid MetaPlaylist file).

-

Each of its objects are linked to a single content, here are the exhaustive -list of its properties:

-
    -
  • -

    url (string): the URL to the original DASH’s MPD or Smooth’s Manifest. -For now, only a subset of such contents is supported, mainly:

    -
      -
    • DASH contents that have their MPD@type set to "static"
      • -
    • Smooth content that have their isLive attribute not set to true -(Simply put, only on-demand contents are supported for the moment).
      • -
    -
    • -
  • -

    startTime (number): time, in seconds, at which the beginning of this -content should be played. -This will correspond to the start time of the first Period in DASH or the -first Chunk defined for Smooth content.

    -
    • -
  • -

    endTime (number): time, in seconds, at which the content should end. It -the original content is longer, it will be finished at that time instead. -The original content should not be shorter.

    -
    • -
  • -

    transport (string): indicates the original streaming protocol. -Can be either of those values for now:

    -
      -
    • "dash": the URL points to a DASH’s MPD
      • -
    • "smooth": the URL points to a Microsoft Smooth Streaming’s Manifest.
      • -
    • "metaplaylist": Yes, it is possible to put MetaPlaylist files inside -other MetaPlaylist files!
      • -
    -
    • -
-

All those contents should be contiguous (meaning that the endTime of one -should be the same value than the startTime of the following one).

-

-

How to actually play a MetaPlaylist content

-

-

Importing the METAPLAYLIST feature

-

The "METAPLAYLIST" feature is not included in the default RxPlayer build.

-

There’s two way you can import it, depending on if you’re relying on the minimal -version or if you prefer to make use of environment variables and build the -player manually.

-

Through the minimal version of the RxPlayer

-

If you’re using the “minimal” version of the RxPlayer (through the -"rx-player/minimal" import), you will need to import:

-
    -
  • the METAPLAYLIST experimental feature
    • -
  • every transport protocol you might want to use.
    • -
-

For example if you need to use MetaPlaylist with both Smooth and DASH contents, -you have to import at least all three as such:

-
import RxPlayer from "rx-player/minimal";
-import { METAPLAYLIST } from "rx-player/experimental/features";
-import { DASH, SMOOTH } from "rx-player/features";
-
-RxPlayer.addFeatures([METAPLAYLIST, DASH, SMOOTH]);
-
-

Through environment variables

-

If you don’t want to go the minimal version’s route and you have no problem with -building yourself a new version of the RxPlayer, you can make use of environment -variables to activate it.

-

This can be done through the RXP_METAPLAYLIST environment variable, which you -have to set to true:

-
RXP_METAPLAYLIST=true npm run build:min
-
-

More information about any of that can be found in the minimal player -documentation.

-

-

Loading a MetaPlaylist content

-

A MetaPlaylist content can simply be played by setting a "metaplaylist" -transport in loadVideo:

-
player.loadVideo({
-  url: "http://www.example.com/metaplaylist.json",
-  transport: "metaplaylist"
-});
-
-

If you declare locally your MetaPlaylist file and do not want to set a URL for -it, you can serve directly the file through the use of a Manifest Loader:

-
player.loadVideo({
-  transport: "metaplaylist",
-  transportOptions: {
-    // Note: `_url` here will be `undefined`
-    manifestLoader(_url, callbacks) {
-      // where `myMetaPlaylistObject` is the MetaPlaylist in either Object or
-      // String form
-      callbacks.resolve({ data: myMetaPlaylistObject });
-    }
-  }
-});
-
-

More infos on the manifestLoader can be found -here.

-

-

Defining an initial position for a dynamic MetaPlaylist

-

As already explained, a MetaPlaylist can either be dynamic or static.

-

For calculating the initial position of those contents, the RxPlayer will obey -the same rules than for other contents.

-

As such, dynamic MetaPlaylist contents will by default start just before the end -of the last defined content which might not be what you want.

-

In those cases, you can make usage of the serverSyncInfos transport options -when calling loadVideo to indicate the current time and construct the -MetaPlaylist by using unix time for each content’s startTime and endTime.

-

The serverSyncInfos option is explained in the transportOptions -documentation.

-

For example, if you trust the user’s system clock to indicate the current live -time (in most cases this is risky however), you can use the Date.now() api:

-
const serverSyncInfos = {
-  serverTimestamp: Date.now(),
-  clientTime: performance.now(),
-};
-
-player.loadVideo({
-  transport: "metaplaylist",
-  url: "https://www.example.com/metaplaylist",
-  transportOptions: { serverSyncInfos },
-});

Minimal player with Feature selection

-

-

Overview

-

The RxPlayer comes with many features, even some you might never need. -For example, you may only care for DASH with TTML subtitles and not about -Smooth streaming, VTT or SRT parsing.

-

Because each implementation has its need, we permit multiple ways to import -the player with limited features. -This principally leads to a smaller file size.

-

This customization can be done through two principal ways:

-
    -
  • -

    by importing a minimal version and then adding only the features your want

    -
    • -
  • -

    by setting environment variables at build time

    -
    • -
-

The first solution is the most straightforward and should be used in most -usecases. The main disadvantages of this solution are that to reduce file size:

-
    -
  • -

    you will need to use a module-bundler or minifier which performs -tree-shaking, like webpack’s -production mode or rollup.

    -
    • -
  • -

    you will need to use the package published on npm (as opposed to the git -repository directly).

    -
    • -
-

The second solution will always work but needs you to build the bundle yourself -through our npm scripts.

-

-

Importing a minimal version

-

-

How it works

-

If you imported the RxPlayer library through the npm package (like via the npm install rx-player command), you can import a minimal version of the player by -importing it from "rx-player/minimal":

-
import MinimalRxPlayer from "rx-player/minimal";
-
-// This player has the same API than the RxPlayer, but with no feature
-// (e.g. no DASH, Smooth or Directfile playback)
-const player = new MinimalRxPlayer();
-
-// use the regular APIs...
-player.setVolume(0.5);
-
-

You then will need to add the features you want on it. Those can be accessed -through the path "rx-player/features":

-
// import the DASH and Smooth features, which will be added to the RxPlayer
-import { DASH, SMOOTH } from "rx-player/features";
-
-

At last you can add those features to the imported RxPlayer class by calling the -special addFeatures static method, which is only present on the minimal -version of the Player:

-
// addFeatures takes an array of features as argument
-MinimalRxPlayer.addFeatures([DASH, SMOOTH]);
-
-

Here is the complete example:

-
import MinimalRxPlayer from "rx-player/minimal";
-import { DASH, SMOOTH } from "rx-player/features";
-
-MinimalRxPlayer.addFeatures([DASH, SMOOTH]);
-
-

There is also “experimental” features. Such features can completely change from -one version to the next - unlike regular features which just follows semantic -versioning. This means that you may have to keep the concerned code up-to-date -each time you depend on a new RxPlayer version. -Such features are imported from "rx-player/experimental/features" instead:

-
import MinimalRxPlayer from "rx-player/minimal";
-import { METAPLAYLIST } from "rx-player/experimental/features";
-
-MinimalRxPlayer.addFeatures([METAPLAYLIST]);
-
-

You can of course depend on both experimental and regular features:

-
import MinimalRxPlayer from "rx-player/minimal";
-import { DASH, SMOOTH } from "rx-player/features";
-import { METAPLAYLIST } from "rx-player/experimental/features";
-
-MinimalRxPlayer.addFeatures([DASH, SMOOTH, METAPLAYLIST]);
-
-

By using the minimal version, you will reduce the final bundle file if -tree-shaking is performed on the final code (like in webpack’s production -mode).

-

The key is just to know which feature does what. The next chapter will list -and explain the role of every one of them.

-

-

List of features

-

Features, which are variables imported from the "rx-player/features" path, -are all objects declared in upper-case.

-

Here is the anotated exhaustive list (notes are at the bottom of the table):

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
FeatureDescription of the feature
SMOOTHEnable Smooth streaming (HSS) playback
DASHEnable DASH playback
DIRECTFILEEnable playback of “directfile” contents
EMEEnable playback of encrypted contents
NATIVE_TEXT_BUFFER [1]Allow to display text tracks through <tracks> elements
HTML_TEXT_BUFFER [1]Allow to display richer text tracks through HTML elements
IMAGE_BUFFER [1]Allow to display thumbnails through the images buffer
NATIVE_SRT_PARSER [2]Parse SRT text tracks for the native text buffer
NATIVE_VTT_PARSER [2]Parse VTT text tracks for the native text buffer
NATIVE_TTML_PARSER [2]Parse TTML text tracks for the native text buffer
NATIVE_SAMI_PARSER [2]Parse SAMI text tracks for the native text buffer
HTML_SRT_PARSER [3]Parse SRT text tracks for the HTML text buffer
HTML_VTT_PARSER [3]Parse VTT text tracks for the HTML text buffer
HTML_TTML_PARSER [3]Parse TTML text tracks for the HTML text buffer
HTML_SAMI_PARSER [3]Parse SAMI text tracks for the HTML text buffer
BIF_PARSER [4]Parse BIF image tracks for the image buffer
LOCAL_MANIFEST [5]Enable playback of “local” contents
METAPLAYLIST [5]Enable playback of “metaplaylist” contents
-
-

Notes:

-

[1]: You will need to also add at least one parser for this type of buffer -for those features to be useful. -(example: NATIVE_SRT_PARSER will parse srt subtitles for the -NATIVE_TEXT_BUFFER)

-

[2]: Those features will only be used if NATIVE_TEXT_BUFFER is an added -feature.

-

[3]: Those features will only be used if HTML_TEXT_BUFFER is an added -feature.

-

[4]: This feature will only be used if IMAGE_BUFFER is an added feature.

-

[5]: Those type of contents are experimental. They should be imported -from rx-player/experimental/features.

-
-

-

Examples

-

To help you choose your features, are some examples that represents common -usecases.

-

unencrypted DASH contents with native webVTT subtitles

-
import RxPlayer from "rx-player/minimal";
-import {
-  DASH,
-  NATIVE_TEXT_BUFFER,
-  NATIVE_VTT_PARSER
-} from "rx-player/features";
-
-RxPlayer.addFeatures([DASH, NATIVE_TEXT_BUFFER, NATIVE_VTT_PARSER]);
-
-

possibly-encrypted DASH contents with HMTL webVTT and TTML subtitles

-
import RxPlayer from "rx-player/minimal";
-import {
-  DASH,
-  EME,
-  HTML_TEXT_BUFFER,
-  HTML_VTT_PARSER,
-  HTML_HTML_PARSER
-} from "rx-player/features";
-
-RxPlayer.addFeatures([
-  DASH,
-  EME,
-  HTML_TEXT_BUFFER,
-  HTML_VTT_PARSER,
-  HTML_TTML_PARSER
-]);
-
-

Smooth contents with thumbnails (BIF) support

-
import RxPlayer from "rx-player/minimal";
-import {
-  SMOOTH,
-  IMAGE_BUFFER,
-  BIF_PARSER
-} from "rx-player/features";
-
-RxPlayer.addFeatures([ SMOOTH, IMAGE_BUFFER, BIF_PARSER ]);
-
-

-

Building with environment variables

-

-

How it works

-

You can also include only the features you need on the RxPlayer library by -building it while having specific environment variables.

-

The code related to the unwanted features should be removed when the final code -is minified (as the corresponding code is made unreachable).

-

To avoid any conflict with other environment variables, they all are named -RXP_<FEATURE-NAME>.

-

For example, the following will remove all code related to Microsoft Smooth -Streaming from the build:

-
RXP_SMOOTH=false npm run build:min
-
-

-

List of environment variables

-

-

RXP_SMOOTH

-

True by default. If set to “false”, all code relative to HSS streaming will be -ignored during a build.

-

-

RXP_DASH

-

True by default. If set to “false”, all code relative to DASH streaming will be -ignored during a build.

-

-

RXP_DIRECTFILE

-

True by default. If set to “false”, all code relative to directfile streaming -will be ignored during a build.

-

-

RXP_LOCAL_MANIFEST

-

False by default. If set to “true”, all code relative to the “local” transport -(to be able to play content offline for example) will be included during a -build.

-

-

RXP_METAPLAYLIST

-

False by default. If set to “true”, all code relative to metaplaylist streaming -will be included during a build.

-

-

RXP_EME

-

True by default. If set to “false”, all code relative to encrypted contents will -be ignored during a build.

-

-

RXP_NATIVE_TTML

-

True by default. If set to “false”, all code relative to TTML parsing for native -text tracks will be ignored during a build.

-

-

RXP_NATIVE_SAMI

-

True by default. If set to “false”, all code relative to SAMI parsing for native -text tracks will be ignored during a build.

-

-

RXP_NATIVE_VTT

-

True by default. If set to “false”, all code relative to VTT parsing for native -text tracks will be ignored during a build.

-

-

RXP_NATIVE_SRT

-

True by default. If set to “false”, all code relative to SRT parsing for native -text tracks will be ignored during a build.

-

-

RXP_HTML_TTML

-

True by default. If set to “false”, all code relative to TTML parsing for html -text tracks[1] will be ignored during a build.

-

-

RXP_HTML_SAMI

-

True by default. If set to “false”, all code relative to SAMI parsing for html -text tracks[1] will be ignored during a build.

-

-

RXP_HTML_VTT

-

True by default. If set to “false”, all code relative to VTT parsing for html -text tracks[1] will be ignored during a build.

-

-

RXP_HTML_SRT

-

True by default. If set to “false”, all code relative to SRT parsing for html -text tracks[1] will be ignored during a build.

-

-

RXP_BIF_PARSER

-

True by default. If set to “false”, all code relative to BIF image parsing will -be ignored during a build.

-

-

RXP_BAREBONE

-

If set to true, no feature is activated by default and all other environment -variables are considered as false by default (unless set).

-

For example, to only activate DASH, you could do:

-
RXP_BAREBONE=true RXP_DASH=true npm run build:min
-
-

-

RXP_ENV

-

Either “production” or “development”. “production” as a default. -In the “development” case:

-
    -
  • logs will be activated
    • -
  • the code will be less tolerant towards unwanted behavior
    • -
  • the code will be less optimized
    • -
-
-

Notes:

-

[1] html text tracks are tracks which are added to a -DOM element instead of a <track> (the latter here being called “native”) tag -for a richer formatting.

parseBifThumbnails

-

parseBifThumbnails is a function allowing to easily parse BIF files, which -is a file format crafted to contain video thumbnails.

-

Those are usually used to give a visual indication of where in a given media you -will seek to when hovering a progress bar.

-

-

About BIF files

-

The BIF format is straightforward. It contains several metadata and then all the -images for the whole content, in their original format (e.g. “jpeg”), -concatenated.

-

-

How to import it

-

parseBifThumbnails is for now considered an “experimental” tool. This means -that its API could change at any new version of the RxPlayer (don’t worry, we -would still document all changes made to it in the corresponding release note).

-

As an experimental tool, it is imported as such:

-
import { parseBifThumbnails } from "rx-player/experimental/tools";
-
-

You can then begin to use it right away.

-

-

How to use it

-

As a simple parser, parseBifThumbnails takes the downloaded BIF file in an -ArrayBuffer form and returns its content under an object format, like this:

-
import { parseBifThumbnails } from "rx-player/experimental/tools";
-
-// optionally, fetch the BIF resource through the usual APIs
-fetch("http://www.example.com/thumbnails.bif").then(function(response) {
-  return response.arrayBuffer(); // obtain an ArrayBuffer response
-}).then(function(buffer) {
-  const parsedBif = parseBifThumbnails(buffer);
-  console.log("parsed BIF:", parsedBif);
-};
-
-

Here is an example of the returned data:

-
{
-  version: "0.0.0.0", // BIF version. For the moment, only "0.0.0.0" is
-                      // specified.
-  images: [    // Array of thumbnails for this content
-    {
-      startTime: 0, // Start position at which the thumbnail should be applied
-                    // to, in milliseconds.
-                    // For example, a time of `5000`, indicates that this
-                    // thumbnail should be shown from the 5 second mark in the
-                    // content (until the next image is displayed instead)
-      image: ArrayBuffer() // The thumbnail itself, in an ArrayBuffer form.
-    },
-    {
-      startTime: 10000,
-      endTime: 20000,
-      thumbnail: ArrayBuffer()
-    },
-    {
-      startTime: 20000,
-      endTime: 30000,
-      thumbnail: ArrayBuffer()
-    },
-    // ...
-  ],
-}

Player events

-

-

-

Overview

-

To communicate about events (like an error or the update of the current video -bitrate) the player use the event listener pattern.

-

As documented in the API, you can call -addEventListener to register a callback for a particular event, like:

-
player.addEventListener("videoBitrateChange", (newVideoBitrate) => {
-  console.log("the video bitrate changed to:", newVideoBitrate)
-});
-
-

You can unregister a callback through the removeEventListener API, -documented here.

-

-

-

Basic events

-

This chapter describes the most important events sent by the player.

-

-

-

playerStateChange

-

payload type: string

-

Emit the current state of the player, every time it changes.

-

This is the event to catch if you want to know when the player is playing, is -paused, is rebuffering, is ended or is stopped.

-

As it is a central part of our API and can be difficult concept to understand, -we have a special page of documentation on player states.

-

-

-

error

-

payload type: Error

-

Triggered when a fatal error happened.

-

A fatal error is an error that led the player to stop playing the current -content.

-

The payload is the corresponding error. See the Player Error -documentation for more information.

-

-

-

warning

-

payload type: Error

-

Triggered each time a minor error happened.

-

This error won’t lead the RxPlayer to stop the content. It can for example be -an HTTP request error, some minor error detected in the content or the current -position being to far below the minimum playable position.

-

The payload is the corresponding error. See the Player Error -documentation for more information.

-

-

-

positionUpdate

-

payload type: Object

-

Emit information about the current position at most every seconds (also emits -every time various player events are received).

-

The object emitted as the following properties:

-
    -
  • -

    position (Number): The current position in the video, in seconds.

    -
    • -
  • -

    duration (Number): The duration of the content.

    -
    • -
  • -

    bufferGap (Number): The gap, in seconds, between the current -position and the end of the current buffered range.

    -
    • -
  • -

    playbackRate (Number): The current playback rate the content is on.

    -
    • -
  • -

    liveGap (Number|undefined): Only for live contents. The gap between -the current position and the “live edge”.

    -
    • -
  • -

    maximumBufferTime (Number|undefined): The maximum time until which -the buffer can currently be filled. That is:

    -
      -
    • -

      for static contents (like VoD), the duration.

      -
      • -
    • -

      for dynamic contents (like live contents), the current maximum available -position (live edge for live contents) minus a security margin we added to -avoid buffering ahead of it.

      -
      • -
    -
    • -
  • -

    wallClockTime (Number|undefined): Only for live contents. The -current time converted to wall-clock time in seconds. -That is the real live position (and not the position as announced by the -video element).

    -
    • -
-

-

-

seeking

-

Emitted when a “seek” operation (to “move”/“skip” to another position) begins -on the currently loaded content.

-

-

-

seeked

-

Emitted when a “seek” operation (to “move”/“skip” to another position) on the -currently loaded content has finished

-

-

-

Track selection events

-

This chapter describes events linked to the current audio, video or text track.

-

-

-

availableAudioTracksChange

-

payload type: Array.<Object>

-
-

Triggered when the currently available audio tracks change (e.g.: at the -beginning of the content, when period changes…).

-

The array emitted contains object describing each available audio track:

-
    -
  • -

    active (Boolean): Whether the track is the one currently active or -not.

    -
    • -
  • -

    id (string): The id used to identify the track. Use it for -setting the track via setAudioTrack.

    -
    • -
  • -

    language (string): The language the audio track is in, as set in -the Manifest.

    -
    • -
  • -

    normalized (string): An attempt to translate the language -property into an ISO 639-3 language code (for now only support translations -from ISO 639-1 and ISO 639-2 language codes). If the translation attempt -fails (no corresponding ISO 639-3 language code is found), it will equal the -value of language

-

A null payload means that video track has been disabled.

-

This event only concerns the currently-playing Period.

-

⚠️ In DirectFile mode, a null payload may be received even if the -video track is still visually active. -This seems due to difficult-to-detect browser bugs. We recommend not disabling -the video track when in directfile mode to avoid that case (this is documented -in the corresponding APIs).

-

Bitrate selection events

-

This chapter describes events linked to audio and/or video bitrates and quality.

-

-

-

availableAudioBitratesChange

-

payload type: Array.<Number>

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

Triggered when the currently available audio bitrates change (e.g.: at the -beginning of the content, when switching the current audio track, when period -changes…).

-

The payload is an array of the different bitrates available, in bits per -seconds.

-

This event only concerns the currently-playing Period.

-

-

-

-

The payload is an array of the different bitrates available, in bits per -seconds.

-

This event only concerns the currently-playing Period.

-

-

-

audioBitrateChange

-

payload type: Number

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

The payload is the new audio bitrate, in bits per seconds. It is emitted every -time it changes (based on the last received segment).

-

-1 when the bitrate is not known.

-

This event only concerns the currently-playing Period.

-

-

-

videoBitrateChange

-

payload type: Number

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

The payload is the new video bitrate, in bits per seconds. It is emitted every -time it changes (based on the last received segment).

-

-1 when the bitrate is not known.

-

This event only concerns the currently-playing Period.

-

-

-

bitrateEstimationChange

-

payload type: Object

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

Information about the last bitrate estimation performed, by type of buffer -(audio, video etc.).

-

Note that this event is sent only if the corresponding buffer type has multiple -Representations for the given content (as bitrate -estimations are only useful in that case).

-

The payload is an object with the following properties:

-
    -
  • -

    type (string): The buffer type

    -
    • -
  • -

    bitrate (Number): The last estimated bandwidth for this buffer type, -in bits per seconds. -This bitrate is smoothed by doing a (complex) mean on an extended period of -time, so it often does not link directly to the current calculated bitrate.

    -

-

Playback information

-

This chapter describes events describing miscellaneous information about the -current content.

-

-

-

periodChange

-

payload type: Object

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

Triggered when the current Period being seen changes.

-

The payload is the corresponding Period. See the Manifest -documentation for more information.

-

-

-

decipherabilityUpdate

-

payload type: Array.<Object>

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

Triggered when a or multiple Representation’s decipherability status were -updated. Which means either:

-
    -
  • A Representation is found to be undecipherable (e.g. the key or license -request is refused)
    • -
  • A Representation is found to be decipherable
    • -
  • A Representation’s decipherability becomes undefined
    • -
-

At this time, this event is only triggered if:

-
    -
  • the current content is an encrypted content
    • -
  • Either the fallbackOnLastTry property was set to true on a rejected -getLicense call or one of the fallbackOn properties was set to true in -the keySystems loadVideo option.
    • -
-

Following this event, the RxPlayer might remove from the current buffers any -data linked to undecipherable Representation(s) (the video might twitch a little -or reload) and update the list of available bitrates.

-

The payload of this event is an Array of objects, each representating a -Representation whose decipherability’s status has been updated.

-

Each of those objects have the following properties:

- -

You can then know if any of those Representations are becoming decipherable or -not through their decipherable property.

-

-

-

streamEvent

-

payload type: Object

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

Event triggered when the player enters the time boundaries of a “stream event”.

-

“Stream events” are metadata that can be defined in various streaming protocols, -which indicates that an application should trigger some action when a specific -time is reached in the content.

-

Those events can either have only a start time or both a start time and an end -time:

-
    -
  • -

    in the case where an event only has a start time, the RxPlayer will trigger -a streamEvent right when the user reaches that time.

    -

    If we return multiple time at that position (for example, when a user seeks -back to it), you will receive a streamEvent as many times for that same -event.

    -
    • -
  • -

    in the case where an event has both a start and end time, the RxPlayer will -trigger a streamEvent when the current position goes inside these time -boundaries (between the start and end time). -This can happen while reaching the start during regular playback but also -when seeking at a position contained between the start and end time.

    -

    The streamEvent event will not be re-sent until the current position -“exits” those time boundaries. If the current position goes out of the -boundaries of that event and then goes into it again (most likely due to the -user seeking back into it), you will again receive a streamEvent for that -same event.

    -
    • -
-

The payload of a streamEvent depends on the source of the event. For example, -it will not have the same format when it comes from a Manifest than when it -comes from the media container. -All possible formats are described in the stream event -tutorial.

-

Note: When an event has both a start and an end time, you can define a onExit -callback on the payload. That callback will automatically be triggered when the -current position goes after the end time or before the start time of that event. -The onExit callback will only be called a single time at most and will only -concern this iteration of the event (and not possible subsequent ones).

-

-

-

streamEventSkip

-

payload type: Object

-
-

⚠️ This event is not sent in DirectFile mode (see loadVideo -options).

-
-

Event triggered when the player skipped the time boundaries of a “stream event” -(you can refer to the streamEvent event for a -definition of what a “stream event” is).

-

This means that the current position the player plays at, immediately changed -from a time before the start time of a “stream event” to after its end time (or -just after its end time for “stream event” without an end time).

-

This is most likely due to the user seeking in the content. A “regular” content -playback which continuously plays the content without seeking shouldn’t trigger -any streamEventSkip event.

-

The payload of a streamEventSkip is the same than for a streamEvent and as -such depends on the source of the event. -All possible formats are described in the stream event -tutorial.

-

Note that unlike streamEvent events, there’s no point to define an onExit -callback on the payload of a streamEventSkip event. This is because this event -was not entered, and will thus not be exited.

-

-

-

Player Options

-

-

-

Overview

-

Player options are options given to the player on instantiation.

-

It’s an object with multiple properties. None of them are mandatory. -For most usecase though, you might want to set at least the associated video -element via the videoElement property.

-

-

-

Properties

-

-

-

videoElement

-

type: HTMLMediaElement|undefined

-

The media element the player will use.

-

Note that this can be a <video> or an <audio> element.

-
// Instantiate the player with the first video element in the DOM
-const player = new Player({
-  videoElement: document.getElementsByTagName("VIDEO")[0]
-});
-
-

If not defined, a <video> element will be created without being inserted in -the document. You will have to do it yourself through the getVideoElement -method to add it yourself:

-
const player = new Player();
-
-const videoElement = player.getVideoElement();
-document.body.appendChild(videoElement);
-
-

-

-

initialVideoBitrate

-

type: Number|undefined

-

defaults: 0

-

This is a ceil value for the initial video bitrate chosen.

-

That is, the first video Representation chosen -will be both:

-
    -
  • inferior or equal to this value.
    • -
  • the closest possible to this value (after filtering out the ones with a -superior bitrate).
    • -
-

If no Representation is found to respect those rules, the Representation with -the lowest bitrate will be chosen instead. Thus, the default value - 0 - -will lead to the lowest bitrate being chosen at first.

-
// Begin either by the video bitrate just below or equal to 700000 bps if found
-// or the lowest bitrate available if not.
-const player = new Player({
-  initialVideoBitrate: 700000
-});
-
-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

initialAudioBitrate

-

type: Number|undefined

-

defaults: 0

-

This is a ceil value for the initial audio bitrate chosen.

-

That is, the first audio Representation chosen -will be:

-
    -
  • inferior or equal to this value.
    • -
  • the closest possible to this value (after filtering out the ones with a -superior bitrate).
    • -
-

If no Representation is found to respect those rules, the Representation with -the lowest bitrate will be chosen instead. Thus, the default value - 0 - -will lead to the lowest bitrate being chosen at first.

-
// Begin either by the audio bitrate just below or equal to 5000 bps if found
-// or the lowest bitrate available if not.
-const player = new Player({
-  initialAudioBitrate: 5000
-});
-
-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

minVideoBitrate

-

type: Number|undefined

-

defaults: 0

-

Minimum video bitrate reachable through adaptive streaming.

-

When the bitrate is chosen through adaptive streaming (i.e., not enforced -manually through APIs such as setVideoBitrate), the player will never switch -to a video quality with a bitrate lower than that value.

-

The exception being when no quality has a higher bitrate, in which case the -maximum quality will always be chosen instead.

-

For example, if you want that video qualities chosen automatically never have -a bitrate lower than 100 kilobits per second you can call:

-
const player = new Player({
-  minVideoBitrate: 100000
-});
-
-

Any limit can be removed just by setting that value to 0:

-
// remove video bitrate lower limit
-player.setMinVideoBitrate(0);
-
-

You can update this limit at any moment with the setMinVideoBitrate API -call.

-

Note that this only affects adaptive strategies. Forcing the bitrate manually -(for example by calling setVideoBitrate) bypass this limit completely.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

minAudioBitrate

-

type: Number|undefined

-

defaults: 0

-

Minimum audio bitrate reachable through adaptive streaming.

-

When the bitrate is chosen through adaptive streaming (i.e., not enforced -manually through APIs such as setAudioBitrate), the player will never switch -to an audio quality with a bitrate higher than that value.

-

The exception being when no quality has a higher bitrate, in which case the -minimum quality will always be chosen instead.

-

For example, if you want that audio qualities chosen automatically never have -a bitrate higher than 100 kilobits per second you can call:

-
const player = new Player({
-  minAudioBitrate: 100000
-});
-
-

Any limit can be removed just by setting that value to 0:

-
// remove audio bitrate lower limit
-player.setMinAudioBitrate(0);
-
-

You can update this limit at any moment with the setMinAudioBitrate API -call.

-

Note that this only affects adaptive strategies. Forcing the bitrate manually -(for example by calling setAudioBitrate) bypass this limit completely.

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

maxVideoBitrate

-

type: Number|undefined

-

defaults: Infinity

-

Maximum video bitrate reachable through adaptive streaming.

-

When the bitrate is chosen through adaptive streaming (i.e., not enforced -manually through APIs such as setVideoBitrate), the player will never switch -to a video quality with a bitrate higher than that value.

-

The exception being when no quality has a lower bitrate, in which case the -minimum quality will always be chosen instead.

-

For example, if you want that video qualities chosen automatically never have -a bitrate higher than 1 Megabits per second you can call:

-
const player = new Player({
-  maxVideoBitrate: 1e6
-});
-
-

Any limit can be removed just by setting that value to Infinity:

-
// remove video bitrate higher limit
-player.setMaxVideoBitrate(Infinity);
-
-

You can update this limit at any moment with the setMaxVideoBitrate API -call.

-

Note that this only affects adaptive strategies. Forcing the bitrate manually -(for example by calling setVideoBitrate) bypass this limit completely.

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

wantedBufferAhead

-

type: Number|undefined

-

defaults: 30

-

Set the default buffering goal, as a duration ahead of the current position, in -seconds.

-

Once this size of buffer is reached, the player won’t try to download new -segments anymore.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

preferredAudioTracks

-

type: Array.<Object|null>

-

defaults: []

-

This option allows to help the RxPlayer choose an initial audio track based on -either language preferences, codec preferences or both.

-

It is defined as an array of objects, each object describing constraints a -track should respect.

-

If the first object - defining the first set of constraints - cannot be -respected under the currently available audio tracks, the RxPlayer will skip -it and check with the second object and so on. -As such, this array should be sorted by order of preference: from the most -wanted constraints to the least.

-

Here is all the possible constraints you can set in any one of those objects -(note that all properties are optional here, only those set will have an effect -on which tracks will be filtered):

-
{
-  language: "fra", // {string|undefined} The language the track should be in
-                   // (in preference as an ISO 639-1, ISO 639-2 or ISO 639-3
-                   // language code).
-                   // If not set or set to `undefined`, the RxPlayer won't
-                   // filter based on the language of the track.
-
-  audioDescription: false // {Boolean|undefined} Whether the audio track should
-                          // be an audio description for the visually impaired
-                          // or not.
-                          // If not set or set to `undefined`, the RxPlayer
-                          // won't filter based on that status.
-
-  codec: { // {Object|undefined} Constraints about the codec wanted.
-           // if not set or set to `undefined` we won't filter based on codecs.
-
-    test: /ec-3/, // {RegExp} RegExp validating the type of codec you want.
-
-    all: true, // {Boolean} Whether all the profiles (i.e. Representation) in a
-               // track should be checked against the RegExp given in `test`.
-               // If `true`, we will only choose a track if EVERY profiles for
-               // it have a codec information that is validated by that RegExp.
-               // If `false`, we will choose a track if we know that at least
-               // A SINGLE profile from it has codec information validated by
-               // that RegExp.
-  }
-}
-
-

This array of preferrences can be updated at any time through the -setPreferredAudioTracks method, documented -here.

-

Examples

-

Let’s imagine that you prefer to have french or italian over all other audio -languages. If not found, you want to fallback to english:

-
const player = new RxPlayer({
-  preferredAudioTracks: [
-    { language: "fra", audioDescription: false },
-    { language: "ita", audioDescription: false },
-    { language: "eng", audioDescription: false }
-  ]
-});
-
-

Now let’s imagine that you want to have in priority a track that contain at -least one profile in Dolby Digital Plus (ec-3 codec) without caring about the -language:

-
const player = new RxPlayer({
-  preferredAudioTracks: [ { codec: { all: false, test: /ec-3/ } ]
-});

At last, let’s combine both examples by preferring french over itialian, italian -over english while preferring it to be in Dolby Digital Plus:

-
const player = new RxPlayer({
-  preferredAudioTracks: [
-    {
-      language: "fra",
-      audioDescription: false,
-      codec: { all: false, test: /ec-3/ }
-    },
-
-    // We still prefer non-DD+ french over DD+ italian
-    { language: "fra", audioDescription: false },
-
-    {
-      language: "ita",
-      audioDescription: false,
-      codec: { all: false, test: /ec-3/ }
-    },
-    { language: "ita", audioDescription: false },
-
-    {
-      language: "eng",
-      audioDescription: false,
-      codec: { all: false, test: /ec-3/ }
-    },
-    { language: "eng", audioDescription: false }
-  ]
-
-

–

-

⚠️ This option will have no effect in DirectFile mode -(see loadVideo options) when either :

-
    -
  • No audio track API is supported on the current browser
    • -
  • The media file tracks are not supported on the browser
    • -
-

-

-

preferredTextTracks

-

type: Array.<Object|null>

-

defaults: []

-

Set the initial text track languages preferences.

-

This option takes an array of objects describing the languages wanted for -subtitles:

-
{
-  language: "fra", // {string} The wanted language
-                   // (ISO 639-1, ISO 639-2 or ISO 639-3 language code)
-  closedCaption: false // {Boolean} Whether the text track should be a closed
-                       // caption for the hard of hearing
-}
-
-

All elements in that Array should be set in preference order: from the most -preferred to the least preferred. You can set null in that array for no -subtitles.

-

When loading a content, the RxPlayer will then try to choose its text track by -comparing what is available with your current preferences (i.e. if the most -preferred is not available, it will look if the second one etc.).

-

This array of preferrences can be updated at any time through the -setPreferredTextTracks method, documented -here.

-

Example

-

Let’s imagine that you prefer to have french or italian subtitles.If not found, -you want no subtitles at all.

-
const player = new RxPlayer({
-  preferredTextTracks: [
-    { language: "fra", closedCaption: false },
-    { language: "ita", closedCaption: false },
-    null
-  ]
-});
-
-

-

⚠️ This option will have no effect in DirectFile mode -(see loadVideo options) when either :

-
    -
  • No text track API is supported on the current browser
    • -
  • The media file tracks are not supported on the browser
    • -
-
-

-

-

preferredVideoTracks

-

type: Array.<Object|null>

-

defaults: []

-

This option allows to help the RxPlayer choose an initial video track.

-

It is defined as an array of objects, each object describing constraints a -track should respect.

-

If the first object - defining the first set of constraints - cannot be -respected under the currently available video tracks, the RxPlayer will skip -it and check with the second object and so on. -As such, this array should be sorted by order of preference: from the most -wanted constraints to the least.

-

When the next encountered constraint is set to null, the player will simply -disable the video track. If you want to disable the video track by default, -you can just set null as the first element of this array (e.g. [null]).

-

Here is all the possible constraints you can set in any one of those objects -(note that all properties are optional here, only those set will have an effect -on which tracks will be filtered):

-
{
-  codec: { // {Object|undefined} Constraints about the codec wanted.
-           // if not set or set to `undefined` we won't filter based on codecs.
-
-    test: /hvc/, // {RegExp} RegExp validating the type of codec you want.
-
-    all: true, // {Boolean} Whether all the profiles (i.e. Representation) in a
-               // track should be checked against the RegExp given in `test`.
-               // If `true`, we will only choose a track if EVERY profiles for
-               // it have a codec information that is validated by that RegExp.
-               // If `false`, we will choose a track if we know that at least
-               // A SINGLE profile from it has codec information validated by
-               // that RegExp.
-  }
-  signInterpreted: true, // {Boolean|undefined} If set to `true`, only tracks
-                         // which are known to contains a sign language
-                         // interpretation will be considered.
-                         // If set to `false`, only tracks which are known
-                         // to not contain it will be considered.
-                         // if not set or set to `undefined` we won't filter
-                         // based on that status.
-}
-
-

This array of preferrences can be updated at any time through the -setPreferredVideoTracks method, documented -here.

-

Examples

-

Let’s imagine that you prefer to have a track which contains at least one H265 -profile. You can do:

-
const player = new RxPlayer({
-  preferredVideoTracks: [ { codec: { all: false, test: /^hvc/ } } ]
-});
-
-

With that same constraint, let’s no consider that the current user is deaf and -would thus prefer the video to contain a sign language interpretation. -We could set both the previous and that new constraint that way:

-
const player = new RxPlayer({
-  preferredVideoTracks: [
-    // first let's consider the best case: H265 + sign language interpretation
-    {
-      codec: { all: false, test: /^hvc/ }
-      signInterpreted: true,
-    },
-
-    // If not available, we still prefer a sign interpreted track without H265
-    { signInterpreted: true },
-
-    // If not available either, we would prefer an H265 content
-    { codec: { all: false, test: /^hvc/ } },
-
-    // Note: If this is also unavailable, we will here still have a video track
-    // but which do not respect any of the constraints set here.
-  ]
-});
-
-
-

For a totally different example, let’s imagine you want to start without any -video track enabled (e.g. to start in an audio-only mode). To do that, you can -simply do:

-
const player = new RxPlayer({
-  preferredVideoTracks: [null]
-});
-
-
-

⚠️ This option will have no effect in DirectFile mode -(see loadVideo options) when either :

-
    -
  • No video track API is supported on the current browser
    • -
  • The media file tracks are not supported on the browser
    • -
-

-

-

maxBufferAhead

-

type: Number|undefined

-

defaults: Infinity

-

Set the maximum kept buffer ahead of the current position, in seconds.

-

Everything superior to that limit (currentPosition + maxBufferAhead) will -be automatically garbage collected.

-

This feature is not necessary as the browser should by default correctly -remove old segments from memory if/when the memory is scarce.

-

However on some custom targets, or just to better control the memory footprint -of the player, you might want to set this limit.

-

Its default value, Infinity, will remove this limit and just let the browser -do this job instead.

-

The minimum value between this one and the one returned by -getWantedBufferAhead will be considered when downloading new segments.

-

⚠️ Bear in mind that a too-low configuration there (e.g. inferior to -10) might prevent the browser to play the content at all.

-

You can update that limit at any time through the setMaxBufferAhead -method.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

maxBufferBehind

-

type: Number|undefined

-

defaults: Infinity

-

Set the maximum kept buffer before the current position, in seconds.

-

Everything before that limit (currentPosition - maxBufferBehind) will be -automatically garbage collected.

-

This feature is not necessary as the browser should by default correctly -remove old segments from memory if/when the memory is scarce.

-

However on some custom targets, or just to better control the memory footprint -of the player, you might want to set this limit.

-

Its default value, Infinity, will remove this limit and just let the browser -do this job instead.

-

You can update that limit at any time through the setMaxBufferBehind -method.

-

–

-

⚠️ This option will have no effect for contents loaded in DirectFile -mode (see loadVideo options).

-

-

-

limitVideoWidth

-

type: Boolean

-

defaults: false

-

With this feature, the possible video -Representations considered are filtered by width:

-

The maximum width considered is the closest superior or equal to the video -element’s width.

-

This is done because the other, “superior” Representations will not have any -difference in terms of pixels (as in most case, the display limits the maximum -resolution displayable). It thus save bandwidth with no visible difference.

-

To activate this feature, set it to true.

-
const player = Player({
-  limitVideoWidth: true
-});
-
-

For some reasons (displaying directly a good quality when switching to -fullscreen, specific environments), you might not want to activate this limit.

-

–

-

⚠️ This option will have no effect for contents loaded :

-
    -
  • In DirectFile mode (see [loadVideo options] -(./loadVideo_options.md#prop-transport)).
    • -
  • On Firefox browsers (version >= 67) : We can’t know if the Picture-In-Picture -feature or window is enabled and we can’t know PIP window size. Thus we can’t -rely on video element size attributes, that may not reflect the real video size -when PIP is enabled.
    • -
-

-

-

throttleVideoBitrateWhenHidden

-

type: Boolean

-

defaults: false

-

The player has a specific feature which throttle the video to the minimum -bitrate when the current video element is considered hidden (e.g. the containing -page is hidden and the Picture-In-Picture mode is disabled) for more than a -minute.

-

To activate this feature, set it to true.

-
const player = Player({
-  throttleVideoBitrateWhenHidden: true
-});
-
-

–

-

⚠️ This option will have no effect for contents loaded :

-
    -
  • In DirectFile mode (see [loadVideo options] -(./loadVideo_options.md#prop-transport)).
    • -
  • On Firefox browsers (version >= 67) : We can’t know if the Picture-In-Picture -feature or window is enabled. Thus we can’t rely on document hiddenness -attributes, as the video may be visible, through the PIP window.
    • -
-

-

-

stopAtEnd

-

type: Boolean

-

defaults: true

-

By default, the player automatically unload the content once it reaches its -end (the player goes to the "ENDED" state).

-

In that case, the only way to play the content again is to (re-)call the -loadVideo API, which will trigger another download of the -Manifest and segments.

-

If you want to be able to seek back in the content after it ended, you may want -to deactivate this behavior. To do so, set stopAtEnd to false.

-
const player = Player({
-  stopAtEnd: false
-});
-
-

-

-

throttleWhenHidden

-

–

-

⚠️ This option is deprecated, it will disappear in the next major release -v4.0.0 (see Deprecated APIs).

-

Please use the -throttleVideoBitrateWhenHidden property -instead, which is better defined for advanced cases, such as Picture-In-Picture.

-

–

-

type: Boolean

-

defaults: false

-

The player has a specific feature which throttle the video to the minimum -bitrate when the current page is hidden for more than a minute.

-

To activate this feature, set it to true.

-
const player = Player({
-  throttleWhenHidden: true
-});
-
-

–

-

⚠️ This option will have no effect for contents loaded :

-
    -
  • In DirectFile mode (see [loadVideo options] -(./loadVideo_options.md#prop-transport)).
    • -
  • On Firefox browsers (version >= 67) : We can’t know if the Picture-In-Picture -feature or window is enabled. Thus we can’t rely on document hiddenness -attributes, as the video may be visible, through the PIP window.

Plugins

-

-

Overview

-

To allow the player to be extended, a system of “plugins” has been added.

-

Those plugins are often under the form of functions passed as an argument to the -loadVideo API call.

-

-

-

segmentLoader

-

The segmentLoader is a function that can be included in the transportOptions -of the loadVideo API call.

-

A segmentLoader allows to define a custom audio/video segment loader (it might -on the future work for other types of segments, so always check the type if you -only want those two).

-

The segment loader is the part performing the segment request. One usecase where -you might want to set your own segment loader is to integrate Peer-to-Peer -segment downloading through the player.

-

To give a complete example, here is a segment loader which uses an XHR (it has -no use, as our implementation does the same thing and more):

-
/**
- * @param {Object} infos - infos about the segment to download
- * @param {string} infos.url - the url the segment request should normally be on
- * @param {Object} infos.adaptation - the Adaptation containing the segment.
- * More information on its structure can be found on the documentation linked
- * below [1]
- * @param {Object} infos.representation - the Representation containing the
- * segment.
- * More information on its structure can be found on the documentation linked
- * below [2]
- * @param {Object} infos.segment - the segment itself
- * More information on its structure can be found on the documentation linked
- * below [3]
-
- * @param {Object} callbacks
- * @param {Function} callbacks.resolve - Callback to call when the request is
- * finished with success. It should be called with an object with at least 3
- * properties:
- *   - data {ArrayBuffer} - the segment data
- *   - duration {Number|undefined} - the duration of the request, in
- *     milliseconds.
- *   - size {Number|undefined} - size, in bytes, of the total downloaded
- *     response.
- * @param {Function} callbacks.progress - Callback to call when progress
- * information is available on the current request. This callback allows to
- * improve our adaptive streaming logic by better predicting the bandwidth
- * before the request is finished.
- * This function should be called with the following properties:
- *   - duration {Number} - the duration since the beginning of the request
- *   - size {Number} - the current size, in bytes, downloaded
- *   - totalSize {Number|undefined} - the whole size of the wanted data, in
- *     bytes. Can be let to undefined when not known.
- * our default implementation instead for this segment. No argument is needed.
- * @param {Function} callbacks.reject - Callback to call when an error is
- * encountered. If you relied on an XHR, it is recommended to include it as an
- * object property named "xhr" in the argument.
- * @param {Function} callbacks.fallback - Callback to call if you want to call
- * our default implementation instead for this segment. No argument is needed.
-
- * @returns {Function|undefined} - If a function is defined in the return value,
- * it will be called if and when the request is canceled.

manifestLoader

-

The manifestLoader is a function that can be included in the -transportOptions of the loadVideo API call.

-

A manifestLoader allows to define a custom Manifest -loader.

-

The Manifest loader is the part performing the Manifest request.

-

Here is a Manifest loader which uses an XHR (it has no use, as our -implementation does the same thing and more):

-
/**
- * @param {string|undefined} url - the url the Manifest request should normally
- * be on.

- * @param {Function} callbacks.resolve - Callback to call when the request is
- * finished with success. It should be called with an object with at least 3
- * properties:
- *   - data {*} - the Manifest data
- *   - duration {Number|undefined} - the duration of the request, in
- *     milliseconds.
- *   - size {Number|undefined} - size, in bytes, of the total downloaded
- *     response.
- *   - url {string|undefined} - url of the Manifest (post redirection if one).
- *   - sendingTime {number|undefined} - Time at which the manifest request was
- *     done as a unix timestamp in milliseconds.
- *   - receivingTime {number|undefined} - Time at which the manifest request was
- *     finished as a unix timestamp in milliseconds.
- * @param {Function} callbacks.reject - Callback to call when an error is

representationFilter

-

The representationFilter is a function that can be included in the -transportOptions of the loadVideo API call.

-

A representationFilter allows you to filter out -Representations (i.e. media qualities) based on -its attributes.

-

The representationFilter will be called each time we load a -Manifest with two arguments:

-
    -
  • -

    representation {Representation}: The concerned Representation. -A Representation structure’s is described in the Manifest structure -documentation.

    -
    • -
  • -

    representationInfos {Object}: Basic information about this -Representation. Contains the following keys:

    -
      -
    • -

      bufferType {string}: The concerned type of buffer. Can be -"video", "audio", "text" (for subtitles) or "image" -(for thumbnail).

      -
      • -
    • -

      language {string|undefined}: The language the Representation -is in, as announced by the Manifest.

      -
      • -
    • -

      normalizedLanguage {string|undefined}: An attempt to translate the -language into an ISO 639-3 code. -If the translation attempt fails (no corresponding ISO 639-3 language -code is found), it will equal the value of language

      -
      • -
    • -

      isClosedCaption {Boolean|undefined}: If true, the Representation -links to subtitles with added hints for the hard of hearing.

      -
      • -
    • -

      isAudioDescription {Boolean|undefined}: If true, the -Representation links to an audio track with added commentary for -the visually impaired.

      -
      • -
    • -

      isDub {Boolean|undefined}): If set to true, this audio track is a -“dub”, meaning it was recorded in another language than the original. -If set to false, we know that this audio track is in an original -language. -This property is undefined if we do not known whether it is in an -original language.

      -
      • -
    -
    • -
-

This function should then returns true if the Representation should be -kept or false if it should be removed.

-

For example, here is a representationFilter that removes video -Representations with a video resolution higher than HD (1920x1080):

-
/**
- * @param {Object} representation - The Representation object, as defined in
- * the documentation linked bellow [1]
- * @param {Object} infos - supplementary information about the given
- * Representation.
- * @returns {boolean}
- */
-function representationFilter(representation, infos) {
-  if (infos.bufferType === "video") {
-    // If video representation, allows only those for which the height and width
-    // is known to be below our 1920x1080 limit
-    const { width, height } = representation;
-    return width != null && height != null && width <= 1920 && height <= 1080;
-  }
-
-  // Otherwise, allow all non-video representations
-  return true;
-}

Player states

-

The player state, that you can obtain either with the -getPlayerState method or through the -playerStateChange -player event, is a central part of our API: it is from -this value that you will know:

-
    -
  • when a new content finished loading
    • -
  • when the content is paused to build buffer
    • -
  • when the content is ended
    • -
  • as a generality, in what “state” is the player currently
    • -
-

As such, it is important this concept is understood when developping with the -rx-player, which is exactly the point of this page.

-

-

List of possible states

-

Today the player can have one of these 9 possible states:

-
    -
  • STOPPED
    • -
  • LOADING
    • -
  • LOADED
    • -

The STOPPED state

-

STOPPED is the default state of the player. It indicates that no content is -playing.

-

To simplify state exploitation, STOPPED is also emitted as a transition state -when loading a new content while another one was currently loaded (or loading). -That way, you can just listen to the STOPPED state to know when the current -content is not loaded anymore.

-

When the player encounters an error, it will also stop and switch -to the STOPPED state.

-

-

The LOADING state

-

The LOADING state indicates that a new content is currently loading. -It appears only after the STOPPED state.

-

That means that the player is currently downloading enough of the content to be -able to play it.

-

While this state is active, most of the content-related APIs (like -setAudioTrack) are not available. You have to wait for the LOADED state for -that.

-

-

The LOADED state

-

LOADED appears only after a LOADING state, and indicates that the current -content can now be played.

-

From this point onward, most of the content-related APIs (like setAudioTrack) -are now available.

-

If the autoPlay loadVideo option has been set to -true, the state will then switch to PLAYING directly. Else, the player will -usually be paused and stay in the LOADED state (there is some edge cases, see -the “Possible state transitions” chapter for more information).

-

-

The PLAYING state

-

Indicates that the player is currently playing the content.

-

-

The PAUSED state

-

Indicates that the player is currently paused in the content.

-

-

The BUFFERING state

-

The content is paused because it needs to build buffer.

-

The player will not play until it gets out of this state.

-

-

The SEEKING state

-

The content is paused because it needs to build buffer after seeking in the -content (this can be seen as a special BUFFERING case).

-

The player will not play until it gets out of this state.

-

-

The ENDED state

-

The player reached the end of the content.

-

If the stopAtEnd player option has been set to -true or not set, the player will immediately stop the content. In that case, -the ENDED state can be considered like the STOPPED state - in terms of what -you can do.

-

Else, it should now be paused at the last frame if a video content is available -at this time and this state acts like what you can expect from HTML5 playback:

-
    -
  • -

    when seeking when the content is ended, you will be paused (even if you -were playing before)

    -
    • -
  • -

    after calling play, you will play back from the beginning

    -
    • -
-

-

The RELOADING state

-

This state indicates that the player needs to “re-load” then content.

-

This can happen for different reasons:

-
    -
  • -

    When you switch the video track for another one, when the previous one was -currently decoding.

    -
    • -
  • -

    When you update manually the audio and video bitrate through respectively -the setAudioBitrate and setVideoBitrate APIs -(Only if you set the manualBitrateSwitchingMode loadVideo option to -"direct").

    -
    • -
-

In those cases, we need to stop and reload the content on the browser-side, due -to browser limitation.

-

While this state is active, multiple player API are unavailable:

-
    -
  • you cannot play or pause
    • -
  • you cannot seek
    • -
  • you cannot obtain the position or duration
    • -
  • you cannot get or switch the available video, text or audio tracks.
    • -
  • you cannot get or switch the available video or audio bitrates.
    • -
-

This is why we sometime recommend to manage this state as if it was the -LOADING state (where those APIs - and other - are also not available).

-

However, the player won’t go to the LOADED state after RELOADING, you will -instead know that it had finished reloading simply when it goes out of this -state (see the “Possible state transitions” chapter for more information).

-

-

Possible state transitions

-

The player goes from one state to another during runtime but those changes does -not happen at random. There is actually possible state transitions (like from -STOPPED to LOADING) and impossible ones (like from LOADING to SEEKING).

-

We will list here every possible state transitions. -Note that we can never have two times the same state consecutively.

Text tracks

-

-

-

Overview

-

The rx-player allows to display text tracks - such as subtitles or closed -captions - directly over your content:

-

Example of a textrack on acontent

-

Adding text tracks to contents can be done by two means:

-
    -
  • by using a Manifest declaring those text tracks
    • -
  • by manually adding text track(s) when you call the loadVideo API
    • -
-

You can then choose the right track through the different text track-related -API, all documented in the general API documentation.

-

-

-

Supported text track formats

-

The rx-player supports the following formats:

-
    -
  • TTML (TTML1, EBU-TT and IMSC1)
    • -
  • WebVTT
    • -
  • SAMI
    • -
  • SRT
    • -
  • TTML embedded in an MP4 file
    • -
  • WebVTT embedded in an MP4 file
    • -
-

-

-

Text tracks indicated in a manifest

-

Each streaming technology supported by the Manifest defines a way to add text -track directly in their Manifests files.

-

This chapter explains what is supported by the RxPlayer.

-

-

-

In DASH

-

In DASH, text tracks are defined by AdaptationSet elements, which have a -contentType attribute equal to text.

-

Those AdaptationSet can also define a lang, codecs and mimeType, -which are then exploited by the RxPlayer.

-
-

The lang attribute is used to know the language the track is in.

-

The RxPlayer understands the following standards:

-
    -
  • ISO 639-1 (2 letters)
    • -
  • ISO 639-2 (3 letters)
    • -
  • ISO 639-3 (3 letters)
    • -
-

More complex combined formats are also understood, as long as it begins by one -of the understood standards, followed by a dash (“-”).

-

For example “en-US” is translated into just “en”, and then inferred to be -english.

-
-

The mimeType attribute is used to know in which format the track is in.

-

The RxPlayer understands the following ones:

-
    -
  • application/ttml+xml: TTML in plain text
    • -
  • text/vtt: WebVTT in plain text
    • -
  • application/x-sami: SAMI in plain text
    • -
  • application/mp4: Text track embedded in an MP4 container.
    • -
  • text/plain: Generic plain text mimeType
    • -
-

For the last two, the codecs attribute of the AdaptationSet will be -exploited to know the exact format.

-
-

The rx-player uses the codecs attribute for text tracks in only two cases:

-
    -
  • the mimeType is equal to application/mp4
    • -
  • the mimeType is equal to text/plain
    • -
-

For the first case, both WebVTT and TTML can be embedded in an MP4 file. To know -which one we’re dealing with, the codecs attribute should be equal to:

-
    -
  • stpp for TTML
    • -
  • wvtt for WebVTT
    • -
-

For the second case ("text/plain"), this is specifically to support plain -SubRip (SRT) subtitles. To use them you need to set codecs simply to -srt.

-
-

To know if we’re dealing with a closed caption text track, the RxPlayer uses the -DVB-DASH specification.

-

That is, an AdaptationSet is inferred to be a closed caption for the hard of -hearing, if it contains an Accessibility descriptor with the following -attributes:

-
    -
  • SchemeIdUri set to urn:tva:metadata:cs:AudioPurposeCS:2007
    • -
  • value set to 2
    • -
-

-

-

In Microsoft Smooth Streaming

-

In Smooth Manifests, a StreamIndex is inferred to be for a text track if its -Type attribute is equal to text.

-
-

The FourCC attribute is used to infer the format of the text track. Only -TTML is understood, and is translated to be a TTML track embedded in an MP4 -container.

-

Adding support for other formats is very simple, open an issue if you want us to -add a standardized FourCC code for another supported format.

-
-

The Language is used to know the language the track is in. The rules are the -same than for DASH:

-

The rx-player understand the following standards:

-
    -
  • ISO 639-1 (2 letters)
    • -
  • ISO 639-2 (3 letters)
    • -
  • ISO 639-3 (3 letters) -More complex combined formats are also understood, as long as it begins by one -of the understood standards, followed by a dash (“-”).
    • -
-

For example “en-US” is translated into just “en”, and then inferred to be -english.

-
-

The Subtype attribute is used to know if the language is a closed caption or -not.

-

At the moment, the RxPlayer infers the track to be a closed caption only if its -value is DESC.

-

-

-

Text tracks added manually

-

It is also possible to add a supplementary text track dynamically, by using the -TextTrackRenderer tool. You can read its documentation -here.

-

-

-

Text track display modes

-

There is two ways the text track can be displayed:

-
    -
  • -

    "native": The text track is displayed in <track> elements, which are -directly in the linked videoElement.

    -
    • -
  • -

    "html": The text track is displayed in a separate <div> element.

    -
    • -
-

The second ones allows for a better track stylisation. The distinction between -those two is pretty simple and is explained -here, in the loadVideo options -documentation.

[1] The buffer gap is the distance between the current time and the buffer time -edge.

-

[2] If the buffer gap is long (more than 5 seconds in default configuration): -From requests computed bandwidths (data size / request time), calculate two -EWMA.

-

[2a] The first, a fast-moving average, falls quickly when estimated bandwidth -falls suddenly.

-

[2b] The second, a slow-moving average, is a bandwidth mean.

-

[3] For quality of service, the player should adapt down quickly, to avoid -buffering situations, and grow up slowly, in order to smoothly change quality. -For this reason, the minimum between the two estimated is considered as a -bitrate threshold. The chosen quality is a quality’s bitrate ceiling.

-

[4] If the buffer gap is too short, it is considered as “starving”:

-

[5] An immediate bandwidth is computed from last or current request. -The quality’s bitrate ceiling relies on it to return the chosen quality.

BOLA Algorithm finds optimal quality -value to minimize playback buffering and maximize buffered quality.

-

[1] BOLA broadly defines minimum buffer steps for which we can allow to download -a quality:

-
                ^

-                |

-
-                                 Buffer gap (s)
-
-

[2] The BOLA estimation is computed each time a segment is appended (thus buffer -gap is updated).

-

The RxPlayer has a mecanism that allows to replace low-quality buffered segments -by higher quality ones if the current conditions improve. -That leads to the buffer gap not increasing when a chunk is added. -That could mislead BOLA, and cause oscillations between chosen qualities.

-

[3] In order to avoid this trend, we compute a maintainability score for the -currently downloaded quality. It is an EWMA - of the ratio between segment duration and -segment download time. If the score points that a quality is “maintainable”, the -algorithm shall not decide to decrease quality and is “allowed” to pick an upper -quality. Conversely, when a quality may not be downloadable fast enough, the -BOLA is “allowed” to decrease the estimated quality, and shall not decide to -increase it.

-

If no maintanaibility score is computed, then BOLA works the regular way.

ABRManager

-

-

Overview

-

The ABRManager (ABR for Adaptive BitRate) is a class which facilitates the -choice between multiple audio/video qualities in function of the current -bandwidth, the network capacities and other specific settings set by the client.

-

It does so by receiving various values such as:

-
    -
  • when network requests begin, progresses or end
    • -
  • stats about the bandwidth of the user
    • -
  • the current status of the buffer (how much of the buffer is left etc.)
    • -
  • DOM events
    • -
  • user settings (maximum authorized bitrate/width etc.)
    • -
  • the available qualities
    • -
-

With all those variables at hand, it then proposes the quality which seems to -be the most adapted, that is the quality which:

-
    -
  • will respect user settings (example: a Maximum bitrate is set)
    • -
  • will maximize the user experience (example: a quality too high for the -network to handle would lead to excessive re-bufferings, but a too low would -be not as pleasant to watch)
    • -
-

In order to estimate the quality that maximizes the playback experience, the ABR -relies on two “estimators”. The bandwidth estimator -picks a quality from network conditions. The -buffer based chooser relies on buffering conditions -to make his choices.

The API

-

The API

-

-

Overview

-

The API is the front-facing part of the code. -It will be the only layer used by applications integrating the RxPlayer library.

-

As such, its main roles are to:

-
    -
  • -

    provide a comprehensive API for the user

    -
    • -
  • -

    translate user order into actions in the player

    -
    • -
  • -

    redirecting events to the user

    -
    • -
-

-

Why is it so big?

-

core/api/public_api.ts is at the time of writing the longest file in all the -RxPlayer, with more than 2000 lines!

-

So why is that, isn’t that a signal that we should split up its role into -multiple files?

-

Well, yes and no. -The reason why it ends up so big is mainly because of the following reasons:

-
    -
  • -

    our API is itself pretty big!

    -
    • -
  • -

    The API needs to have a considerable state because most of the other modules -rely on Observables.

    -

    I’ll explain: -The API can’t just interogate at any time the concerned module as if it was -a class with methods. Here most modules are functions which send events.

    -

    The problem is that a library user might want to have an information at any -given moment (for example, the current bitrate), which internally is only -sent as an event by some module. -It is thus the role of the API to store that information when it receives -this event to then communicate it back to the user.

    -
    • -
-

A huge part of what is defined in that file is actually the entire API, as -small functions. We found that having the whole API in a single file was -actually useful.

-

Likewise, as the API is a single class with a huge private state, being able -to see those state mutations in a single file allows us to better think about -how it all works.

-

Still, we did some efforts to reduce the size of that file. For example, some -long argument-parsing code has been moved out of this file, into -core/api/option_parsers. We might find other ways to reduce that size in the -future, but that’s not a main concern for now.

-

-

Subparts

-

To facilitate those actions, the API relies on multiple building blocks:

-
    -
  • -

    the Clock

    -

    Provide an Observable emitting regularly the current viewing conditions for -the Player. Many RxPlayer modules rely on that clock.

    -
    • -
  • -

    the TrackChoiceManager

    -

    Ease up text/audio/video track switching to provide a simple-to-use API.

    -
    • -
  • -

    the option parsers

    -

    Parse options given to some RxPlayer API calls, to add default parameters -and provide inteligible warnings/errors

    -
    • -

The EMEManager

-

-

Overview

-

The EMEManager in the core/eme directory allows to easily interface with -the browser APIs for decrypting a crypted content, it follows the Encrypted -Media Extensions recommandations.

-

Like most modules in the RxPlayer, the EMEManager is just a function - called -a single time - returning an Observable.

-

This Observable then return event corresponding to different milestones related -to decrypting the content.

The fetchers

-

-

Overview

-

The fetchers is the part of the code interacting with the transport protocol, -defined in transports, to download and parse:

-
    -
  • the Manifest
    • -
  • media Segments
    • -
-

Each of those task is performed by a discrete component of the fetchers:

-
    -
  • -

    The Manifest fetcher is used to download and parse the manifest file.

    -
    • -
  • -

    The SegmentFetcherCreator is used to create Segment fetchers, -allowing to download and parse media segments.

    -
    • -
-

-

The Manifest fetcher

-

The Manifest fetcher allows to download and parse the Manifest/Playlist of the -current transport protocol to return an unified Manifest object.

-

This is the part of the code that interacts with transports to perform the -request and parsing of the Manifest file.

-

-

The SegmentFetcherCreator

-

The SegmentFetcherCreator allows to easily perform segment downloads for the -rest of the code. -This is the part of the code that interacts with the transport protocols - -defined in transports - to load and parse media segments.

-

To do so, the SegmentFetcherCreator creates “segment fetchers” of different -types (example: a video or audio segment fetcher) when you ask for it. -Through those fetchers, you can then schedule various segment requests with a -given priority.

-

The priority of this request is then corroborated with the priority of all -requests currently pending in the SegmentFetcherCreator (and not only with -those on the current segment fetcher) to know when the request should -effectively be done - more prioritary requests will be done first.

-

During the lifecycle of the request, the segment fetcher will communicate about -data and metrics through several means - documented in the code.

-

-

Priorization

-

Each Segment request can be linked to a priorization number. -Such number will indicate which segment is needed more immediately than other -(the lower it is, the higher the priority of the segment is).

-

This is for example used to indicate that a very close video segment has a -higher priority than some distant audio segment (both might be scheduled at the -same time depending on the situation).

-

If the request has no priorization number, the lowest priorization number -(the highest priority) will be set on it: 0

-

Basically, any new request will have their priorization number compared to the -one of the current request(s) done by the SegmentFetcherCreator:

-
    -
  • -

    if no request is already pending, we perform the request immediately

    -
    • -
  • -

    if (and only if) this priorization number is higher (so lower priority) than -all current requests, this new request will be postponed to let the -higher-priority ones finish.

    -
    • -
  • -

    If a new request has a priorization number lower or equal than all current -downloads, we perform the request immediately without interrupting the -current, lower-priority ones.

    -
    • -
-

The priority of a download can be updated at any time, until this request either -has finished, was canceled or failed. The same rules apply when the priorization -number is updated (if this request is already pending, we keep it going in any -case).

File architecture

-

This page describes how the player files are organized. Each chapter go through -a single directory or subdirectory, in alphabetical order.

-

-

-

The demo/ directory: Demos of rx-player implementations

-

Demonstration of functional codebases implementing the rx-player.

-

At the time of writing, there are two demos:

-
    -
  • -

    full: Demo with a graphic interface, written with the React library, to -showcase what the player can do

    -
    • -
  • -

    standalone: Just expose the rx-player in window, to allow scripted -interactions with it in the console. The player is linked to a video tag in -the displayed page.

    -
    • -
-

-

-

The dist/ directory: Player builds

-

Store the player builds of the last version released.

-

Contains two files: the minified (rx-player.min.js) and the non-minified -files (rx-player.js). Both are automatically generated with scripts at every -new release.

-

Two directories, namely _esm5.raw and _esm5.processed can also be -generated in here if the right scripts are called. -These allow to publish more modular codebases to npm.

-

-

-

The doc/ directory: Player documentation

-

Documentation, mostly in markdown, of various subjects related to the rx-player:

-
    -
  • -

    API documentation

    -
    • -
  • -

    code architecture documentation

    -
    • -
  • -

    documentation to help developpers (to use APIs, switch versions, know which -APIs are deprecated)

    -
    • -
-

-

-

The scripts/ directory: scripts

-

Contains various scripts used to help the test and the management of the player -code.

-

For example:

-
    -
  • generating one of the demo and starting the server to run it
    • -
  • deploying the demo or doc to github pages
    • -
  • updating the player version
    • -
  • generating the rx-player build before publishing on npm
    • -
-

-

-

The src/ directory: the source code

-

The src contains the entire source code of the rx-player.

-

It is subdivized into subdirectories which are defined here.

-

-

-

src/compat/: The compatibility files

-

src/compat contains functions allowing to use browser APIs in a -cross-browser manner.

-

For example, if an event does not have the same name depending on the browser, -the compat files will expose a simple function allowing to make sure the event -is catched, taking the task of registering the right event on the callback -given.

-

Every functions needed in the rest of the code are exported in -compat/index.js, making it easier to import (e.g. by just doing -import { whatINeed } from "../compat";)

-

-

-

src/core/: The core files

-

Defines the logic and behavior of the player, regardless of the browser and of -the streaming technology used.

-

That’s where:

-
    -
  • the api is defined
    • -
  • the MSE and EME APIs are called and managed
    • -
  • the segments are downloaded and pushed to then be decoded by the browser
    • -
  • adaptive bitrate strategies are set
    • -
-

This directory contains other subdirectories which are listed in the next -chapter.

-

-

-

src/errors/: Error definitions

-

Contains the definition of the error classes used in the rx-player and -accessible through the API.

-

-

-

src/experimental/: Experimental features

-

You will find here experimental features. Those are tested features who might -completely change their API in new player versions.

-

-

-

src/features/: Feature switching

-

This manage activated or deactivated features (e.g. DASH, TTML subtitles -parsing).

-

It exports an object defining the different activated features and provide utils -to initialize and update them.

-

-

-

src/manifest/: The Manifest class

-

Defines a common Manifest class, regardless of the streaming technology (DASH, -HSS…). This class is then used by the rest of the RxPlayer, to allow -interaction with it without considering the underlying technology used.

-

-

-

src/transports/: The transport protocols

-

Defines a common interface for multiple streaming technologies (DASH, HSS).

-

What is exported there are functions to load:

-
    -
  • Manifests/MPDs
    • -
  • video/audio segments
    • -
  • subtitles tracks
    • -
  • image tracks
    • -
-

For different streaming technologies.

-

As in most of the code of the rx-player, everything used in the other parts of -the code is exported in the index.js file at the root of this directory.

-

-

-

src/parsers/: The parsers

-

Functions to parse various formats into the same interface.

-

The parsed data being either:

-
    -
  • Manifest documents: DASH’s MPD, HSS’s Manifest…
    • -
  • containers: ISOBMFF (CMAF, fMP4, MP4), Matroska (MKV, WEBM)
    • -
  • text tracks: TTML, SAMI, SRT, WebVTT
    • -
  • image containers: BIF
    • -
-

-

-

src/typings/: Typescript typings

-

This directory contains only declaration files for TypeScript. It is -automatically added as a typeRoots when the TypeScript code is transpiled.

-

-

-

src/utils/: The utils

-

This directory contains general helpers which are used in different parts of the -rx-player code.

-

-

-

The src/core/ directory

-

As written in the previous chapter, this is the “core” of the player, where the -logic is defined.

-

As this directory is versatile and complicated, it also deserves its own chapter.

-

-

-

src/core/abr/: The adaptive bitrate code

-

Defines an ABRManager class which manages the adaptive streaming part of the -player.

-

This manager takes various observables/options as inputs to record the current -situation of the player, give an opinion about the best media tracks to choose, -and provide methods allowing to get/set various ABR-related options.

-

Despite containing several files and using several classes, only the ABRManager -defined in abr/index.js should be needed by the rest of the core. -This allows to isolate this complex part and facilitate future refactoring and -improvements.

-

-

-

src/core/api/: The API definition

-

Defines the rx-player API. This is the part the library user will directly -interact with.

-

-

-

src/core/stream/: Load the right segments

-

The code there calculate which segments should be downloaded, ask for their -download and push the segments into the SegmentBuffers.

-

-

-

src/core/eme/: Encryption management

-

Defines functions allowing to handle encrypted contents through the EME APIs.

-

-

-

src/core/fetchers/: The fetchers

-

Handle the segments and Manifest downloading pipelines (load and parse) as -defined in the src/transports/ directory.

-

This is the layer directly interacting with the transport part (HSS, DASH). -It facilitates the role of loading the Manifest and new segments for the rest of -the core.

-

-

-

src/core/segment_buffers/: The media buffers

-

Code allowing to interact with the media buffers called SegmentBuffers.

-

Those are the Objects to which segments are pushed so they can be decoded at the -right time.

-

For Audio and Video, SegmentBuffers rely on a native SourceBuffer object, -already provided by the browser, -for other type of contents (like subtitles), we rely on completely custom media -buffers implementations.

-

-

-

src/core/init/: Content initialization

-

This is the central part which download manifests, initialize MSE and EME APIs, -instanciate the central StreamOrchestrator (which will allow to download and -push segments so the content can play) and link together many subparts of the -player.

-

-

-

src/**/tests: the unit tests directories

-

You will find multiple directories named __tests__ in the RxPlayer. -Those contain unit tests and are put in the same directory than the code it -tests.

-

Most unit tests files contain only tests for a single source file. Those will -be put directly at the root of __tests__ under the name -<ORIGINAL_SRC_FILE>.test.ts (where <ORIGINAL_SRC_FILE> is the filename of -the tested file).

-

__tests__ directories can also contain files defining tests for multiple files -contained in the tested directory. -Those can be quicker to write and easier to maintain at the expense of being -less thorough.

-

Those type of “global” unit tests are put in a special __global__ directory, -itself directly at the root of the corresponding __tests__ directory. -Their filename don’t follow the same convention than single-source unit tests -but should still be suffixed by .test.ts.

-

-

-

The tests/ directory: the player’s tests

-

This directory contains most testing code for the RxPlayer.

-

The rx-player contains multiple type of tests:

-
    -
  • -

    integration tests: test the whole player API and its behavior when playing -different contents. The main goal of those tests is to quickly detect -regressions.

    -

    Those are entirely written in the tests/integration sub-directory.

    -
    • -
  • -

    conformance tests: Provide standalone page which allows to quickly test the -support of various media-related API on a given device and/or browser.

    -

    The html documents you will find here are basic templates that can be easily -modified and deployed for quick testing.

    -
    • -
  • -

    unit tests: test specific parts of the code. The main goal here is to check -the implementation of smaller units of code.

    -

    They are written alongside the code, in __tests__ -directories. All its configuration can be found at the root of the project, -in jest.config.js (we use the jest library for unit tests).

    -
    • -
  • -

    memory tests: test the memory usage of the player.

    -

    They are entirely written in the tests/memory subdirectory.

RxPlayer Architecture documentation

-

-

Overview

-

The files in this directory and subdirectories establish a documentation about -the RxPlayer’s architecture.

-

They are here to help you understand the way the player works, by describing -the different bricks and algorithms that come into play.

-

Note: As some terms used here might be too foreign or slightly different than -the one you’re used to, we also wrote a list of terms and definitions used by -the RxPlayer here.

-

-

Organization of the documentation

-

The RxPlayer is heavily modularized.

-

This helps us maintaining the code and providing evolutions more quickly, as the -various modules use few well-defined interfaces with the rest of the code.

-

Like the code, the documentation is also divided in multiple parts, which link -one by one to a module in the code.

-

Such modules are (with link to their respective documentation, if one):

-
    -
  • -

    the API

    -

    Defines the public API of the RxPlayer and provides abstractions to help -implementing it.

    -
    • -
  • -

    the Init

    -

    Initialize playback and connects the different modules between one another.

    -
    • -
  • -

    the EMEManager

    -

    Negotiate content decryption.

    -

    Only used for contents with DRM (Digital Right Management).

    -
    • -
  • -

    the ABRManager

    -

    Helps to choose the best quality in the current content by analyzing the -current network, user settings and viewing conditions.

    -
    • -
  • -

    the Stream

    -

    Choose which media segments to download and push them to media buffers (here -called the SegmentBuffers) to then be able to decode them.

    -

    Various files documenting the Stream architecture should be available in -the doc/architecture/stream directory.

    -
    • -
  • -

    the SegmentBuffers

    -

    Implement media buffers on which loaded segments will be pushed. -The corresponding media data contained in them will then be decoded at the -right time.

    -

    Those buffers can depend on browser implementations (for example for audio -and video contents, we rely on SourceBuffer JS objects) or may be -completely defined in the code (for example, text track buffers in the -"html" textTrackMode are entirely defined in the RxPlayer).

    -

    Those SegmentBuffers have added niceties over just being simple data -buffers. For example, they include an inventory which allows to retrieve the -metadata about every segments that is still contained within it.

    -
    • -
  • -

    the transports

    -

    Perform manifest/segment requests, and parse them.

    -

    transports in essence abstracts the transport protocol used (example: -Smooth Streaming/DASH) to provide an unified definition of a segment or -manifest to the other modules. -In theory, it should be the only directory to update when adding / -modifying / deleting a transport protocol

    -
    • -
  • -

    the fetchers

    -

    Link the transports module with the rest of the code, to download -segments, download/refresh the manifest and collect data (such as the -user’s bandwidth) for the other modules.

    -
    • -
-

The RxPlayer also has a multitude of isolated helpers (for manifest management, -segment parsing, browser compatibility, feature switching, error handling etc.) -which are used by these different modules.

-

A documentation about the file organization of the project is available -here.

-

-

Global architecture

-

To better understand the player’s architecture, you can find below a -(simplified!) schema of it:

The Init

-

-

Overview

-

The Init is the part of the code starting the logic behind playing a content.

-

Its code is written in the src/core/init directory.

-

Every time you’re calling the API to load a new video, the init is called by it -(with multiple options).

-

The Init then starts loading the content and communicate back its progress to -the API through events.

-
                 +-----------+

-

During the various events happening on content playback, the Init will create / -destroy / update various player blocks. Example of such blocks are:

-
    -
  • -

    Adaptive streaming management

    -
    • -
  • -

    DRM management

    -
    • -
  • -

    Manifest loading, parsing and refreshing

    -
    • -
  • -

    Buffer management

    -
    • -
  • -

    …

    -
    • -
-

-

Usage

-

Concretely, the Init is a function which returns an Observable. -This Observable:

-
    -
  • -

    will automatically load the described content on subscription

    -
    • -
  • -

    will automatically stop and clean-up infos related to the content on -unsubscription

    -
    • -
  • -

    communicate on various streaming events through emitted notifications

    -
    • -
  • -

    throw in the case of a fatal error (i.e. an error interrupting playback)

    -
    • -
-

-

Communication between the API and the Init

-

Objects emitted by the Observable is the only way the Init should be able to -communicate with the API.

-

The API is then able to communicate back to the Init, either:

-
    -
  • -

    by Observable provided by the API as arguments when the Init function was -called

    -
    • -
  • -

    by emitting through Subject provided by the Init, as a payload of one of -its event

    -
    • -
-

Thus, there is three ways the API and Init can communicate:

-
    -
  • -

    API -> Init: When the Init function is called (so a single time)

    -
    • -
  • -

    Init -> API: Through events emitted by the returned Observable

    -
    • -
  • -

    API -> Init: Through Observables/Subjects the Init function is in possession -of.

    -
    • -
-

-

Emitted Events

-

Events allows the Init to reports milestones of the content playback, such as -when the content is ready to play.

-

It’s also a way for the Init to communicate information about the content and -give some controls to the user.

-

For example, as available audio languages are only known after the manifest has -been downloaded and parsed, and as it is most of all a user preference, the -Init can emit to the API, RxJS Subjects allowing the API to “choose” at any -time the wanted language.

-

-

Playback rate management

-

The playback rate (or speed) is updated by the Init.

-

There can be three occasions for these updates:

-
    -
  • -

    the API set a new Speed (speed$ Observable).

    -
    • -
  • -

    the content needs to build its buffer.

    -

    In which case, the playback speed will be set to 0 (paused) even if the -API set another speed.

    -
    • -
  • -

    the content has built enough buffer to un-pause. -The regular speed set by the user will be set again in that case.

The SegmentBuffers

-

-

Overview

-

The core/segment_buffers directory contains the part of the code directly -related to the insertion and removal of media segments to a buffer for later -decoding.

-

This is either done through native SourceBuffers, which are JavaScript objects -implemented by the browser or a custom buffer implementation entirely defined -in the code of the RxPlayer.

-

The interface through which the RxPlayer’s code push segment is called the -SegmentBuffer, it comes on top of the buffer implementation (regardless if it -comes from native SourceBuffer objects or if it is a custom one).

-

A SegmentBuffer is defined for a type of media (e.g. “video”, “audio”, -“text”…) they are defined in the src/core/segment_buffers/implementations -directory.

-

Here’s a simplified architecture schema of the code in that directory:

SegmentBuffersStore

-

The SegmentBuffersStore is the main export from there. -It facilitates the creation and destruction of these SegmentBuffers.

-

Its roles are to:

-
    -
  • -

    announce which types of SegmentBuffer can be currently created on the -HTMLMediaElement (example of a type of buffer would be “audio”, “video” or -“text”).

    -

    For example, no “video” SegmentBuffer should be created on an <audio> -element (though it wouldn’t cause any problem, it would be useless -as video cannot be rendered here). To give another example, you should not -create a “text” SegmentBuffer if no text track parser has been added to -the RxPlayer.

    -
    • -
  • -

    Create only one SegmentBuffer instance per type of buffer.

    -

    Multiple SegmentBuffer for a single type could lead to browser issues -and to conflicts in the RxPlayer code.

    Provide a synchronization mechanism to announce when all SourceBuffers are -ready to receive segments.

    -

    I’ll explain:

    -

    SourceBuffers are browser implementations for media data buffers. -They typically are used by the “video” and “audio” SegmentBuffer.

    -

    Among several other constraints, all SourceBuffers needed to play a -given content should be created before we can start pushing segments to any -of them. This is a browser limitation.

    -

    This is where this synchronization mechanism can become useful. The -SegmentBuffersStore will signal when all of the SourceBuffers -needed for the given contents are created, so that the rest of the RxPlayer -knows when it can begin to push segments to those.

    -

    Note that this means that SourceBuffers for an un-needed type (e.g. an -audio content won’t need a video SourceBuffer) have to be explicitely -“disabled” here, as the SegmentBuffersStore cannot know whether it should -wait until those SourceBuffers are created of if you just don’t need it.

    -

-

SegmentBuffers implementations

-

A SegmentBuffer is an Object maintaining a media buffer for a given type (e.g. -“audio”, “video”, “text” etc.) used for later decoding.

-

There exists several SegmentBuffer implementations in the RxPlayer’s code -depending on the type concerned. -An implementation takes the form of a class with a well-defined API shared with -every other implementations. It allows to push segments, remove data and -retrieve information about the data that is contained within it.

-

At its core, it can either rely on a browser-defined SourceBuffer Object or -can be entirely defined in the code of the RxPlayer.

-

A SegmentBuffer also keeps an inventory containing the metadata of all -segments currently contained in it, with the help of a SegmentInventory -Object (see corresponding chapter).

-

It is the main interface the rest of the RxPlayer code has with media buffers.

-

-

BufferGarbageCollector

-

The BufferGarbageCollector is a function used by the RxPlayer to -periodically perform “garbage collection” manually on a given -SegmentBuffer.

-

It is based on the following building bricks:

-
    -
  • -

    A clock, which is an observable emitting the current time (in seconds) when -the garbage collection task should be performed

    -
    • -
  • -

    The SegmentBuffer on which the garbage collection task should run

    -
    • -
  • -

    The maximum time margin authorized for the buffer behind the current -position

    -
    • -
  • -

    The maximum time margin authorized for the buffer ahead of the current -position

    -
    • -
-

Basically, each times the given clock ticks, the BufferGarbageCollector will -ensure that the volume of data before and ahead of the current position does not -grow into a larger value than what is configured.

-

For now, its code is completely decoupled for the rest of the code in that -directory. This is why it is not included in the schema included on the top of -this page.

-

-

The SegmentInventory

-

The SegmentInventory keeps track of which segments are currently bufferized -to avoid unnecessary re-downloads.

-

You can have more information on it in the SegmentInventory -documentation.

SegmentInventory

-

-

Overview

-

The SegmentInventory is a class which registers some information about every -segments currently present in a SegmentBuffer.

-

One of them is created for every new SegmentBuffer.

-

This helps the RxPlayer to avoid re-downloading segments unnecessarily and know -when old one have been garbage collected. -For example, we could decide not to re-download a segment in any of the -following cases:

-
    -
  • -

    The same segment is already completely present in the SegmentBuffer

    -
    • -
  • -

    The same segment is partially present in the SegmentBuffer (read: a part -has been removed or garbage collected), but enough is still there for what -we want to play

    -
    • -
  • -

    Another segment is in the SegmentBuffer at the wanted time, but it is the -same content in a better or samey quality

    -
    • -
-

On the contrary, we need to download the segment in the following cases:

-
    -
  • -

    No segment has been pushed at the given time

    -
    • -
  • -

    A segment has been pushed, but at a lower quality than what we currently -want

    -
    • -
  • -

    A segment has been pushed at a sufficient quality, but we miss to much of it -for our needs (too much has been garbage collected, removed or the segment -is just too short).

    -
    • -
  • -

    A segment has been pushed but is not exactly the content we want -(example: it is in another language)

    -
    • -
-

Thanks to the SegmentInventory, we can infer on which situation we are at any time.

-

-

Implementation

-

The SegmentInventory is merely a “Store”, meaning it will just store and -process the data you give to it, without searching for the information itself.

-

It contains in its state an array, the inventory, which stores every segments -which should be present in the SegmentBuffer in a chronological order.

-

To construct this inventory, three methods can be used:

-
    -
  • -

    one to add information about a new chunk (part of a segment or the whole -segment), which should have been pushed to the SegmentBuffer.

    -
    • -
  • -

    one to indicate that every chunks from a given segment have been pushed.

    -
    • -
  • -

    one to synchronize the currently pushed segments with what the -SegmentBuffer says it has buffered (which can be different for example -after an automatic garbage collection).

    -
    • -
-

After calling the synchronization one, you should be able to tell which parts of -which segments are currently living in your SegmentBuffer.

The Stream

-

-

Overview

-

The Stream is the part of the RxPlayer choosing the right segments to -download, to then push them to the corresponding media buffers (called -SegmentBuffers) so they can later be decoded.

-

To do so, they receive inputs on both what the chosen track should be and on the -estimated optimal quality for those tracks. By then monitoring what has already -been buffered and the current playback conditions, they can make an educated -guess on what segments should be loaded and pushed at any given time.

-

-

The StreamOrchestrator

-

The StreamOrchestrator is the main entry point to interact with the -Stream.

-

It completely takes care of segment downloading and pushing for a whole content.

-

To do so, it creates the right PeriodStreams depending on the current -playback conditions. -For more information on it, you can look at the StreamOrchestrator -documentation.

-

-

The PeriodStream

-

The PeriodStream creates and destroys AdaptationStreams for a single -Manifest’s Period and a single type of buffer (e.g. “audio”, “video”, “text” -etc.).

-

It does so after asking through an event which Adaptation has to be chosen for -that Period and type.

-

It also takes care of creating the right “SegmentBuffer” for its associated -type, if none was already created for it.

-

-

The AdaptationStream

-

The AdaptationStream creates and destroys RepresentationStreams for a -single manifest’s Adaptation (such as a particular audio language, a video track -etc.) based on the current conditions (network bandwidth, browser -conditions…).

-

The RepresentationStream will then have the task to do the -segment downloading and pushing itself.

-

-

The RepresentationStream

-

The RepresentationStream is the part that actually monitors the buffer to -deduce which segments should be downloaded, ask to download them and then give -the order to push them to the SegmentBuffer.

-

You can have more information on it in the RepresentationStream -documentation.

RepresentationStream

-

-

Overview

-

The RepresentationStream download and push segments linked to a given -Representation.

-

It constructs a list of segments to download, which depend on the current -playback conditions. -It then download and push them to a linked SegmentBuffer (the media buffer -containing the segments for later decoding).

-

Multiple RepresentationStream observables can be ran on the same -SegmentBuffer without problems, as long as they are linked to different -Periods of the Manifest. -This allows for example smooth transitions between multiple periods.

-

-

Return value

-

The RepresentationStream returns an Observable which emits multiple -notifications depending on what is happening at its core, like:

-
    -
  • -

    when segments are scheduled for download

    -
    • -
  • -

    when segments are pushed to the associated SegmentBuffer

    -
    • -
  • -

    when the Manifest needs to be refreshed to obtain information on possible

    -
    • -
  • -

    whether the RepresentationStream finished to load segments until the end -of the current Period. This can for example allow the creation of a -RepresentationStream for the next Period for pre-loading purposes.

    -
    • -
  • -

    whether there are discontinuities: holes in the stream that won’t be filled -by segments and can thus be skipped

    -
    • -
-

-

Queue Algorithm

-

The RepresentationStream depends on a central algorithm to make sure that the -right segments are scheduled for download at any time.

-

This algorithm constructs a queue of segments to download at any time, and -regularly checks that the segment currently downloaded still corresponds to the -currently most needed Segment.

-

This list of segments is based on a simple calculation between the current -position and the buffer size we want to achieve. -This list goes then through multiple filters to ensure we’re not queueing them -unnecessarly. Such cases would be, for example, if the segment is already -present in the SegmentBuffer at a better quality.

-

For a clock based on various video events, the strategy is the following:

-
    -
  1. -

    let segmentQueue be an empty array.

    -
    2. -
  2. -

    On each clock tick, calculate segmentsNeeded, an Array of needed -segments (read: not yet downloaded) from the current time to the buffer -size goal.

    -

    Note that the steps 2 to 5 can run multiple times while waiting for -a request - happening in step 5 and 8. If that happens, -segmentQueue should equal the last value it has been given.

    -
    3. -
  3. -

    check if there’s a segment currently downloaded (launched in step 8)

    -

    3-1. If there is none, let segmentQueue be equal to segmentsNeeded

    -

    3-2. If there is one but for a segment different than the first element -in segmentsNeeded or if segmentsNeeded is empty, abort -this request and let segmentQueue be equal to segmentsNeeded.

    -

    3-3. If there is one and is for the same segment than the first element -in segmentsNeeded, let segmentQueue be equal to -segmentsNeeded without its first element.

    -
    4. -
  4. -

    if segmentQueue is empty, go back to 2.

    -
    5. -
  5. -

    check if there’s a pending segment request (happening in step 8):

    -

    5-1. if there’s no segment request, continue

    -

    5-1. if there’s a pending segment request, go back to 2

    -
    6. -
  6. -

    Let currentSegment be the first segment of segmentQueue

    -
    7. -
  7. -

    Remove the first segment from segmentQueue (a.k.a. currentSegment)

    -
    8. -
  8. -

    perform a request for currentSegment and wait for it to finish. -During this time, step 2 to 5 can run in parallel, and as such -SegmentQueue can be mutated during this process.

    -
    9. -
  9. -

    Once the request is finished, run those tasks in parallel:

    -

    9-1. Append the segment to the corresponding SegmentBuffer

    -

    9-1. go back to step 4.

StreamOchestrator

-

-

Overview

-

To be able to play a content, the player has to be able to download chunks of -media data - called segments - and has to push them to media buffers, called -SegmentBuffers in the RxPlayer code.

-

In the RxPlayer, the StreamOrchestrator is the entry point for performing all -those tasks.

-

Basically, the StreamOrchestrator:

-
    -
  • -

    dynamically creates various SegmentBuffers depending on the needs of the -given content

    -
    • -
  • -

    orchestrates segment downloading and “pushing” to allow the content to -play in the best conditions possible.

    -
    • -
-

-

Multiple types handling

-

More often than not, content are divised into multiple “types”: “audio”, “video” -and “text” segments, for example. They are often completely distinct in a -Manifest and as such, have to be downloaded and decoded separately.

-

Each type has its own media buffer. For “audio”/“video” contents, we use -regular browser-defined MSE SourceBuffers. -For any other types, such as “text” and “image”, those buffers are entirely -defined in the code of the RxPlayer.

-

We then create a different Stream for each type. Each will progressively -download and push content of their respective type to their respective -media buffer:

-
- AUDIO STREAM -
-|======================    |
-
-- VIDEO STREAM -
-|==================        |
-
-- TEXT STREAM -
-|========================  |
-
-- IMAGE STREAM -
-|====================      |
-
-

(the | sign delimits the temporal start and end of the buffer linked to a -given Stream, the = sign represent a pushed segment in the corresponding -buffer)

-

-

A special case: SourceBuffers

-

Media buffers created for the audio and/or video types rely on a native -(implemented by the browser) SourceBuffer Object implementation.

-

Media buffers relying on native SourceBuffers have several differences with the -other “custom” (entirely defined in the RxPlayer) types of media buffers:

-
    -
  • -

    They are managed by the browser where custom ones are implemented in JS. -As such, they must obey to various browser rules, among which:

    -
      -
    1. -

      They cannot be lazily created as the content plays. We have to -initialize all of them beforehand.

      -
      2. -
    2. -

      They have to be linked to a specific codec.

      -
      3. -
    3. -

      The SourceBuffer has to be linked to the MediaSource, and they have -to the MediaSource after the media HTMLElement has been linked to the -MediaSource

      -
      4. -
    -
    • -
  • -

    They are in a way more “important” than custom ones. If a problem happens -with a SourceBuffer, we interrupt playback. For a custom media buffer, we -can just deactivate it for the rest of the content.

    -

    For example, a problem with subtitles would just disable those with a -warning. For a video problem however, we fail immediately.

    -
    • -
  • -

    They affect buffering when custom media buffers do not (no text segment for -a part of the content means we will just not have subtitles, no audio -segment means we will completely stop, to await them)

    -
    • -
  • -

    They affect various API linked to the media element in the DOM. Such as -HTMLMediaElement.prototype.buffered. -Custom media buffers do not.

    -
    • -
-

Due to these differences, media buffers relying on SourceBuffers are often -managed in a less permissive way than custom ones:

-
    -
  • -

    They will be created at the very start of the content

    -
    • -
  • -

    An error coming from one of them will lead us to completely stop the content -on a fatal error

    -
    • -
-

-

PeriodStreams

-

The DASH streaming technology has a concept called Period. Simply put, it -allows to set various types of content successively in the same manifest.

-

For example, let’s take a manifest describing a live content with -chronologically:

-
    -
  1. an english TV Show
    2. -
  2. an old italian film with subtitles
    3. -
  3. an American film with closed captions.
    4. -
-

Example:

-
08h05              09h00                       10h30                now
-  |==================|===========================|===================|
-        TV Show               Italian Film            American film
-
-

Those contents are drastically different (they have different languages, the -american film might have more available bitrates than the old italian one).

-

Moreover, even a library user might want to be able to know when the italian -film is finished, to report about it immediately in a graphical interface.

-

As such, they have to be considered separately - in a different Period:

-
        Period 1                Period 2                Period 3
-08h05              09h00                       10h30                now
-  |==================|===========================|===================|
-        TV Show               Italian Film            American film
-
-

In the RxPlayer, we create one PeriodStream per Period and per type.

-

PeriodStreams are automatically created/destroyed during playback. The job of -a single PeriodStream is to process and download optimally the content linked -to a single Period and to a single type:

-
- VIDEO BUFFER -
-
-     PERIOD STREAM
-08h05              09h00
-  |=========         |
-        TV Show
-
-
-- AUDIO BUFFER -
-
-     PERIOD STREAM
-08h05              09h00
-  |=============     |
-        TV Show
-
-
-- TEXT BUFFER -
-
-     PERIOD STREAM
-08h05              09h00
-  |======            |
-        TV Show
-
-

To allow smooth transitions between them, we also might want to preload content -defined by a subsequent Period once we lean towards the end of the content -described by the previous one. -Thus, multiple PeriodStreams might be active at the same time:

-
+----------------------------   AUDIO   ----------------------------------+

Multi-Period management

-

The creation/destruction of PeriodStreams is actually done in a very precize -and optimal way, which gives a higher priority to immediate content.

-

To better grasp how it works, let’s imagine a regular use-case, with two periods -for a single type of buffer:

-
-

Let’s say that the PeriodStream for the first Period (named P1) is currently -actively downloading segments (the “^” sign is the current position):

-
   P1
-|====  |
-   ^
-
-

Once P1 is full (it has no segment left to download):

-
   P1
-|======|
-   ^
-
-

We will be able to create a new PeriodStream, P2, for the second Period:

-
   P1     P2
-|======|      |
-   ^
-
-

Which will then also download segments:

-
   P1     P2
-|======|==    |
-   ^
-
-

If P1 needs segments again however (e.g. when the bitrate or the language is -changed):

-
   P1     P2
-|===   |==    |
-   ^
-
-

Then we will destroy P2, to keep it from downloading segments:

-
   P1
-|===   |
-   ^
-
-
-

Once P1, goes full again, we re-create P2:

-
   P1     P2
-|======|==    |
-   ^
-
-

Note that we still have the segment pushed to P2 available in the corresponding -media buffer

-

When the current position go ahead of a PeriodStream (here ahead of P1):

-
   P1     P2
-|======|===   |
-        ^
-
-

This PeriodStream is destroyed to free up ressources:

-
          P2
-       |===   |
-        ^
-
-
-

When the current position goes behind the first currently defined PeriodStream:

-
          P2
-       |===   |
-    ^
-
-

Then we destroy all previous PeriodStreams and [re-]create the one needed:

-
   P1
-|======|
-    ^
-
-

In this example, P1 is full (as we already downloaded its segments) so we also -can re-create P2, which will also keep its already-pushed segments:

-
   P1     P2
-|======|===   |
-    ^
-
-
-

For multiple types of buffers (example: audio and video) the same logic is -repeated (and separated) as many times. An audio PeriodStream will not -influence a video one:

-
---------------------------   AUDIO   --------------------------------
-     Period 1         Period 2
-|================|=============   |
-     ^
-
----------------------------   VIDEO   --------------------------------
-     Period 1
-|=======         |
-     ^
-
-----------------------------   TEXT   --------------------------------
-     Period 1         Period 2          Period 3
-|================| (NO SUBTITLES) |================   |
-     ^
-
-

At the end, we should only have PeriodStream[s] for consecutive Period[s]:

-
    -
  • The first chronological one is the one currently seen by the user.
    • -
  • The last chronological one is the only one downloading content.
    • -
  • In between, we only have full consecutive PeriodStreams.
    • -
-

-

Communication with the API

-

Any “Stream” communicates to the API about creations and destructions of -PeriodStreams respectively through "periodStreamReady" and -"periodStreamCleared" events.

Transport code

-

-

Overview

-

The transports code in the transports/ directory is the code translating -the streaming protocols available into a unified API.

-

Its roles are to:

-
    -
  • -

    download the Manifest and parse it into an object that can be understood -by the core of the rx-player

    -
    • -
  • -

    download segments, convert them into a decodable format if needed, and -report important information about them (like the duration of a segment)

    -
    • -
  • -

    give networking metrics to allow the core to better adapt to poor networking -conditions

    -
    • -
-

As such, most network request needed by the player are directly performed by -the transports code.

-

Note: the only HTTP request which might be done elsewhere would be the request -for a directfile content. That request is not done explicely with a JavaScript -API but implicitely by the browser (inclusion of an src attribute).

-

-

Implementation

-

This code is completely divided by streaming protocols used. -E.g. DASH streaming is entirely defined in its own directory and the same -thing is true for Smooth Streaming or MetaPlaylist contents.

-

When playing a DASH content only the DASH-related code will be called. When -switching to a Smooth Streaming content, only the Smooth Streaming code -will be used instead.

-

To allow this logic, any streaming protocol exposed in transports exposes -the same interface and abstracts the difference to the rest of the code. -For the core of the rx-player, we do not have any difference between playing -any of the streaming protocols available.

-

This also means that the code relative to a specific streaming technology is -within the transports directory. -This allows to greatly simplify code maintenance and evolutivity. For example, -managing a new streaming protocol would mainly just need us to add some code -there (you might also need to add parsers in the parsers directory). Same -thing for adding a new feature to e.g. DASH or Smooth.

-

Each streaming protocol implementation present in the transports code exports -a single transport function.

-

The object returned by that function is often referenced as the transport pipelines. It is documented here.

-

-

MetaPlaylist implementation

-

A MetaPlaylist is a specific case, as it wraps other streaming protocols.

-

More documentation about it can be found in the corresponding API -documentation.

-

Architecture information on it can also be found here.

MetaPlaylist

-

The MetaPlaylist is a specific kind of transport: a playlist of different -Manifest. -Its principle and usage is defined here.

-

-

How the original Manifest files are considered

-

To play a MetaPlaylist content, each manifest it depends on has to be -downloaded and parsed through their original logic (a MPD through DASH’s -logic and a Smooth Manifest through Smooth’s logic).

-

We then merge each of these Manifest, to construct an internal -Manifest object with the same structure and properties -than we would have with a DASH or Smooth manifest.

-

The trick is to consider each of those original Manifest as different Periods -(like DASH Periods). The trick works here because the RxPlayer’s definition of a -transport (and of the underlying properties) is much more flexible than in DASH. -If an original MPD already has multiple Periods, each of them are also -converted as different RxPlayer’s Period so that no feature from the original -content is lost.

-

Each of those Period is then concatenated one after the other thanks to the time -information announced in the MetaPlaylist file.

-

-

How about the segments

-

The exploitation of segment metadata is even trickier.

-

In DASH or Smooth, the URL of each segment could be constructed from the -starting time of each of those segments.

-

The problem here is that a MetaPlaylist player has to mutate those to place -them at the position indicated in the MetaPlaylist’s JSON instead.

-

To simplify everything, we choose to rely on a simple but effective wrapper on -top of the original transport protocol.

-

When the core logic of the player wants to load a segment from the network, that -wrapper translate back the data as if we’re just playing the original content at -its original position. -How it works: the wrapper removes a specific time offset from the wanted -segment’s metadata, before contacting the transport’s logic.

-

When giving back the segment to the core logic of the player, the wrapper first -update those loaded segment with the wanted position data. -How it works: the wrapper adds back the time offset it previously substracted -from the wanted segment’s metadata before giving it back to the core logic.

-

To illustrate, it kind of goes like this:

-
+----------------+ 1. Ask for segments infos from t to t+n  +--------------+
-|                | ---------------------------------------> |              |

-   | |  HSS  |  |                                                    |  |
-   | |       |  |                                                    |  |
-   | +-------+  |                                                    |  |
-   | +-------+  |  6. Ask to download non-offseted (normal) segments |  |
-   | |       |  | <--------------------------------------------------+  |
-   | |  ...  |  |                                                       |
-   | |       |  |  7. Gives normal segment                              |
-   | +-------+  | ------------------------------------------------------+
-   +------------+
-
-

To make sure the segment is pushed at the right moment and doesn’t overlap other -contents, we make heavy use of some specific SourceBuffer properties:

-
    -
  • the timestampOffset property allows to set a specific offset
    • -
  • appendWindowStart allows to limit the starting time of the pushed segment
    • -
  • appendWindowEnd allows to limit the ending time of the pushed segment
    • -

Transport pipeline

-

-

Definition

-

Each streaming protocol defines a function that takes some options in arguments -and returns an object. This object is often referenced as the transport pipelines of the streaming protocol.

-

This object then contains the following functions:

-
    -
  • a Manifest “loader”
    • -
  • a Manifest “parser”
    • -
  • multiple segment “loaders” (one per type of buffer, like “audio”, “video”, -“text”…).
    • -
  • multiple segment “parsers”
    • -
-

As you can see, there’s two recurrent concepts here: the loader and the parser.

-

-

A loader

-

A loader in the transport pipeline is a function whose role is to “load” the -resource.

-

Depending on the streaming technology, this can mean doing a request or just -creating it from the information given.

-

Its concept can be illustrated as such:

-
  INPUT:                                 OUTPUT:
-  ------                                 -------
-  URL and other information  +--------+  loaded resource
-  about the wanted resource  |        |
-============================>| LOADER |==============================>
-                             |        |
-                             +--------+
-
-

As the wanted resource could be obtained asynchronously (like when an HTTP -request has to be performed), the loader returns an Observable and the resource -is then emitted through it.

-

This Observable will throw on any problem arising during that step, such as an -HTTP error.

-

In some specific conditions, the loader can also emit the wanted resource in -multiple sub-parts. This allows for example to play a media file while still -downloading it and is at the basis of low-latency streaming. -To allow such use cases, the segment loaders can also emit the wanted resource -by cutting it into chunks and emitting them through the Observable as they are -available. -This is better explained in the related chapter below.

-

-

A parser

-

A parser’s role is to extract the data and other important information from a -loaded resource. -It is connected in some ways to the response of the loader (which gives the -loaded resource) and will be the last step before that resource is actually -handled by the rest of the player.

-

Its concept can be illustrated as such:

-
  INPUT:                                OUTPUT:
-  ------                                -------
-  loaded resource +                     exploitable resource and
-  resource information +     +--------+ parsed information from it
-  request scheduler [1]      |        |
-============================>| PARSER |==============================>
-                             |        |
-                             +--------+
-
-

The parser returns an Observable which will emit the parsed resource when done.

-

This Observable will throw if the resource is corrupted or miss crucial -information.

-

[1] the parser could also need to perform requests (e.g. it needs to fetch the -current time from a server). -In such cases, the parser is given a special callback, which allows it to -receive the same error-handling perks than a loader, such as multiple retries, -just for those requests.

-

-

Manifest loader

-

The Manifest loader is the “loader” downloading the Manifest (or MPD) file.

-

It is a function which receives as argument the URL of the manifest and then -returns an Observable emitting a single time the corresponding Manifest when it -finished downloading it:

-
  INPUT:                              OUTPUT:
-  ------                              -------
-  Manifest/MPD URL      +----------+  Manifest in a generic format
-                        |          |  (e.g. string, Document...)
-=======================>| MANIFEST |=================================>
-                        |  LOADER  |
-                        |          |
-                        +----------+
-
-

-

Manifest parser

-

The Manifest parser is a function whose role is to parse the Manifest in its -original form to convert it to the RxPlayer’s internal representation of it.

-

It receives in argument the downloaded Manifest, some Manifest-related -information (e.g. its URL) and a specific function called scheduleRequest, -allowing it to ask for supplementary requests before completing (e.g. to fetch -the current time from an URL or to load sub-parts of the Manifests only known -at parse-time).

-

This function returns an Observable wich emits a single time the parsed -Manifest:

-
 INPUT:                                       OUTPUT:
- ------                                       -------
- Manifest in a generic format +  +----------+ RxPlayer's `Manifest`
- URL + request scheduler         |          | structure
- ===============================>| MANIFEST |===========================>
-                                 |  PARSER  |
-                                 |          |
-                                 +----------+
-
-

-

Segment loader

-

A Transport pipeline declares one Segment loader per type of buffer (e.g. audio, -text, video…)

-

A segment loader is the “loader” for any segment. Its role is to retrieve a given -segment’s data.

-

It receives information linked to the segment you want to download:

-
    -
  • The related Manifest data structure
    • -
  • The Period it is linked to
    • -
  • The Adaptation it is linked to
    • -
  • The Representation it is linked to
    • -
  • The Segment object it is linked to
    • -
-

It then return an Observable which send events as it loads the corresponding -segment.

-
  INPUT:                              OUTPUT:
-  ------                              -------
-  Segment information   +----------+  Segment in a generic format
-                        |          |  (e.g. ArrayBuffer, string...)
-=======================>| SEGMENT  |=================================>
-                        |  LOADER  |
-                        |          |
-                        +----------+
-
-

The events sent in output depend on the “mode” chosen by the loader to download -the segment. There are two possible modes:

-
    -
  • -

    the regular mode, where the loader wait for the segments to be completely -downloaded before sending it

    -
    • -
  • -

    the low-latency mode, where the loader emits segments by chunks at the same -time they are downloaded.

    -
    • -
-

The latter mode is usually active under the following conditions:

-
    -
  • low-latency streaming is enabled through the corresponding loadVideo -option
    • -
  • we’re loading a DASH content.
    • -
  • we’re not loading an initialization segment.
    • -
  • the segment is in a CMAF container
    • -
  • the Fetch JS API is available
    • -
-

In most other cases, it will be in the regular mode.

-

You can deduce which mode we are in simply by looking a the events the loader -sends.

-

In the regular mode, any of the following events can be sent through the -Observable:

-
    -
  • -

    "progress": We have new metrics on the current download (e.g. the amount -currently downloaded, the time since the beginning of the request…)

    -
    • -
  • -

    "data-created": The segment is available without needing to perform a -network request. This is usually the case when segments are generated like -Smooth Streaming’s initialization segments. -The segment’s data is also communicated via this event.

    -

    The "data-created" event, when sent, is the last event sent from the -loader. The loader will complete just after emitting it.

    -
    • -
  • -

    "data-loaded": The segment has been compeletely downloaded from the -network. The segment’s data is also communicated via this event.

    -

    Like "data-created", the "data-loaded" will be the last event sent by -the loader. -This means that you will either have a single "data-created" event or a -single "data-loaded" event with the data when the segment has been loaded -succesfully.

    -
    • -
-

In the low-latency mode, the following events can be sent instead:

-
    -
  • -

    "progress": We have new metrics on the current download (e.g. the amount -currently downloaded, the time since the beginning of the request…)

    -
    • -
  • -

    "data-chunk": A sub-segment (or chunk) of the data is currently available. -The corresponding sub-segment is communicated in the payload of this event.

    -

    This event can be communicated multiple times until a -"data-chunk-complete" event is received.

    -
    • -
  • -

    "data-chunk-complete": The segment request just finished. All -corresponding data has been sent through "data-chunk" events.

    -

    If sent, this is the last event sent by a segment loader. The loader will -complete just after emitting it.

    -
    • -
-

-

Segment parser

-

A segment parser is a function whose role is to extract some information from -the segment’s data:

-
    -
  • what its precize start time and duration is
    • -
  • whether the segment should be offseted when decoded and by what amount
    • -
  • the decodable data (which can be wrapped in a container e.g. subtitles in an -ISOBMFF container).
    • -
  • the attached protection information and data to be able to decrypt that -segment.
    • -
-

It receives the segment or sub-segment as argument and related information:

-
 INPUT:                                       OUTPUT:
- ------                                       -------
- Segment in a generic format +                Decodable data + time
- isChunked? [1] + Segment        +----------+ information + segment protection
- information                     |          | information
- ===============================>| SEGMENT  |===========================>
-                                 |  PARSER  |
-                                 |          |
-                                 +----------+
-
-

[1] The parser can make different guess on the time information of the -segment depending on if the loaded segment corresponds to the whole segment or -just a small chunk of it. The isChunked boolean allows it to be aware of that.

-

Differences between DASH’ AdaptationSets and the rx-player “Adaptation”

-

The RxPlayer defines an Adaptation object (also sometimes called Track) -which follow as close as possible the concept of the AdaptationSet in -the DASH protocol.

-

However, to answer practically to some of the features allowed by DASH while -still respecting the DASH-IF “IOP”, we had to -take some (minor) freedom with our interpretation of it.

-

-

Merging of multiple AdaptationSets into a single Adaptation

-

The main difference is that all similar AdaptationSet which are marked as -“seamlessly switchable” between one another are merged into a single -Adaptation in the player.

-

-

Why do we do that

-

This “switchable” concept is for example used in cases were multiple encryption -keys are present for different Representation (e.g. due to limitations coming -from right holders).

-

The problem is that the DASH-IF tells us that all Representation in a given -AdaptationSet have to use the same license. -This means that in the aforementioned case, the concerned Representation -have to be divided into multiple AdaptationSet. In a player, different -AdaptationSet means different “tracks” and thus a player won’t try to -automatically switch between them.

-

This means that our adaptive algorithm won’t be able to set the right quality -and that the library user would have to manually manage that instead.

-

Fortunately, the DASH-IF IOP planned a work-around for that kind of situation: -To allow a player to seamlessly switch between multiple AdaptationSets, the -DASH-IF allows a specific node, called SupplementalProperty to be added as -children of the concerned AdaptationSets (with a specific value).

-

However, this brings another set of issues in the rx-player, where this -separation would lead to an excessively complicated API.

-

-

What do we do

-

We thus decided to “merge” the AdaptationSets into a single Adaptation if -all those conditions are filled:

-
    -
  • -

    they both support seamless-switching between one-another (i.e. they both -contain a SupplementalProperty node with the right values)

    -
    • -
  • -

    they represent the same type of content (“audio”, “video” or “text”)

    -
    • -
  • -

    they are of the same language, if one (letter-for-letter in the manifest)

    -
    • -
  • -

    they have the same accessibility information (e.g. both are closed -captions or audio description for the visually impaired).

    -
    • -
-

If any of these conditions is not filled, the concerned AdaptationSets stay -separated and the player will not try to switch between them.

presentationTimeOffset

-

The presentationTimeOffset is an attribute which can be encountered in an MPD -(the “manifest” of the DASH streaming technology).

-

-

Overview

-

Simply put, this attribute allows to correct an offset present in the media -segments once those are decoded.

-

One of the possible usecase would be creating an on demand MPD from a subsection -of an already-existing content, without modifying directly the concerned -segments nor their (possibly time-based) URLs.

-

Another main usecase is when handling multi-Periods MPDs. -Segments in newer Periods already need to consider an offset, corresponding to -the start of the given Period. -In those cases, the presentationTimeOffset might allows to “cancel” out this -offset. This can be useful if the corresponding segments already define the -right time.

-

-

Simple example

-

For example, let’s imagine some on-demand content with a duration of 2 hours. -To stay simple, this content begins at 00:00:00.000 and ends at -01:08:00.000 (1 hour and 8 minutes).

-
CONTENT:
-
-00:00:00.000                                                        01:08:00.000
-    |====================================================================|
-
-
-

Now let’s say that we want to create a new on-demand content, which is only a -sub-part from this content. -For example, we will take the subpart going from 00:05:24.000 to -00:12:54.000 (for a duration of 00:07:30.000).

-

-00:00:00.000                                                        02:00:00.000
-    |====|------|========================================================|
-            ^
-      Subpart going from 00:05:24 to 00:12:54.000
-
-
-

Because we might not want to use money uselessly, we want to create this new -content simply by creating a new MPD, and without touching the already created -segments, nor their URLs.

-

In that condition, we will still need the client to know that this content -actually have an offset of 00:05:24.000. If it does not know that, we will -just think that the content begins at a default 00:00:00.000 time.

-

Letting the client think that the content begins at the default 00:00:00.000 -time could lead to several issues:

-
    -
  • -

    it might not be able to request the right first segments (as the URLs could -be time-based)

    -
    • -
  • -

    even if it does, it might not be able to actually play the content, as we’re -pushing segments corresponding to a 00:05:24.000 while the browser is -still waiting for the 00:00:00.000 ones (in that case, we would just have -an infinite buffering state).

    -
    • -
  • -

    even if it does, the client timeline will announce a wrong time, offseted 5 -minutes and 24 seconds too late.

    -
    • -
-

This is where the presentationTimeOffset comes into play. In our simple -example, this value will just announce an offset of 00:05:24.000 (under the -form of an integer with a timescale to convert it into seconds), and the client -will know what to do.

-

What the client has to do here is:

-
    -
  • begin to play at 0 secods
    • -
  • ask the right segments, by adding this offset to the one it thinks it needs
    • -
  • remove the offset from the segment before decoding it
    • -
-

-

Time conversions

-

The presentationTimeOffset is linked to multiple other time attributes of an -MPD, especially the start of the Period concerned, and of course the time -of the segment.

-

We will enounce below a simple equation which put their relation into -perspective.

-

To understand this equation, we will need to define some variables:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
VariableDefinition
PTOThe “presentationTimeOffset” attribute of the MPD
mediaTimeThe start time announced in the segment
TSTimescale used by PTO and segmentTime, to transform them into seconds
periodStartStart time of the given period, in seconds
presentationTimeThe time at which the segment will be shown, in seconds
-
    mediaTime        PTO
-  -------------  -  -----  +  periodStart  =  presentationTime
-       TS            TS
-
-

-

Easier conversion: the timestampOffset

-

As seen in the previous chapter, to convert the media time (time announced in -the segments) into the presentation time (time that will be shown to the user), -you will need to use both also include three other variables:

-
    -
  • -

    the start of the period

    -
    • -
  • -

    the presentationTimeOffset

    -
    • -
  • -

    the timescale used by the presentationTimeOffset and the media time

    -
    • -
-

As a convenient plus, those three variables rarely change for a given period.

-

To simplify the conversion, we can thus define a new variable using those three. -This is what the timestampOffset is all about.

-

Let’s go back to the equations in the previous chapters, to isolate those three -into the really simple equation: -mediaTime/TS + timestampOffset = presentationTime (you can refer to the -previous chapter to understand what those variables means)

-

-  mediaTime       PTO
- -----------  -  -----  +  periodStart  =  presentationTime
-     TS           TS
-
-  mediaTime           PTO
- -----------  + ( -  -----  +  periodStart ) =  presentationTime
-     TS               TS
-
-                          PTO                                       PTO
-  timestampOffset  =  -  -----  +  periodStart  =  periodStart  -  -----
-                          TS                                        TS
-
-
-

With timestampOffset defined, it becomes easy to go back and forth between -the mediaTime and the presentationTime:

-
                       mediaTime
-presentationTime  =   -----------  +  timestampOffset
-                          TS
-
-mediaTime  =  (  presentationTime  -  timestampOffset  )  *  TS
-
-
-

As an added bonus, SourceBuffers defined in the HTML5 MediaSource Extentions -also have a timestampOffset property -, which -means exactly the same thing as defined here!

-

-

In the RxPlayer

-

Now that we have all of those concepts out of the way, how are we going to use -it, in the RxPlayer?

-

The RxPlayer has A LOT of time-related values defined for a given segment:

-
    -
  • -

    the time defined in the segment itself (mediaTime)

    -
    • -
  • -

    the time displayed when playing it in the HTMLMediaElement -(presentationTime)

    -
    • -
  • -

    the time possibly set in the request (requestSegmentTime)

    -
    • -
  • -

    the time as announced in the corresponding attribute of the manifest -(manifestTime)

    -
    • -
  • -

    the time used in the corresponding Segment Object in the RxPlayer -(playerTime)

    -
    • -
  • -

    the time used in the buffered APIs of a HTMLMediaElement or SourceBuffer -(bufferedTime)

    -
    • -
  • -

    …

    -
    • -
-

As it turns out it’s a lot simpler once you make two isolated groups:

-
    -
  • -

    the manifest group, which uses the non-offseted mediaTime.

    -

    In this group you have:

    -
      -
    • the mediaTime (duh)
      • -
    • the manifestTime
      • -
    • the requestSegmentTime
      • -
    -
    • -
  • -

    the real time group, which uses the offseted presentationTime.

    -

    In this group you have:

    -
      -
    • the presentationTime
      • -
    • the playerTime
      • -
    • the bufferedTime
      • -
    -
    • -
-

The manifest group is then only used in the transports code of the -RxPlayer. -Meanwhile, the real time group is used everywhere else.

-

It’s actually the transports code that does most of the conversion for the -rest of the code (removing the offset when requesting new segments, re-adding it -once the segment is downloaded.

-

To be able to offset those segments in the SourceBuffer, those are still -informed of course of the timestampOffset by the transports code. -Then, this timestampOffset will be exploited only by the final decoding -code.

At what position does the RxPlayer start a content

-

At what position does the RxPlayer start a content

-

-

Overview

-

When you give it a content to load, the RxPlayer has to set at one point the -starting playback position.

-

This documentation page explain how that position is calculated.

-

Basically, we can be in one of those four different situations:

-
    -
  • -

    a valid startAt option has been set to loadVideo, in which case we use -it to define the initial position.

    -
    • -
  • -

    no startAt option has been set and we’re playing a VoD content.

    -
    • -
  • -

    no startAt option has been set and we’re playing a live content.

    -
    • -
  • -

    no startAt option has been set and we’re playing a directfile content.

    -
    • -
-

-

About the minimum and maximum position

-

Regardless of your current situation, the minimum and maximum position of the -content might be calculated and used when defining that starting position.

-

Those positions are inferred directly from the Manifest (when not playing a -directfile content). -Most Manifests declare every segments currently available. In that case, we can -simply use the start of the first announced segment as a minimum position and the -end of the last one as a maximum.

-

In some other Manifest files, segment availability is not clearly announced. -In those cases, the minimum and maximum positions use other properties declared -in the Manifest, often by making usage of a synchronized clock between the -client and the server.

-

For “directfile” contents, we directly interrogate the browser to obtain the -duration of the content. The minimum position here is always inferred to be 0 -(for the moment at least).

-

-

When a startAt option has been set

-

You can define yourself the start position at which we should play. This is -configurable thanks to the startAt option, documented -here in the API documentation.

-

Please note however that there is a catch: every of the possible values you -will set will be “bounded” to the maximum and minimum position actually detected -for the content.

-

This means that if your startAt indicate that we should start at a position of -10 seconds but the content starts at 15 seconds, we will actually start -at 15 seconds instead.

-

You can check at which position we actually loaded when the player’s state -(accessible either through the getPlayerState method or through the -playerStateChanged event) changed to "LOADED".

-

-

When no startAt option has been set and we’re playing a VoD content

-

For VoD contents, we will just start to play at the minimum detected position in -the Manifest.

-

-

When no startAt option has been set and we’re playing a live content

-

For live contents, we have here three cases:

-
    -
  • -

    In the case where we have a clock synchronization mechanism with the -server[1] and if the current date can be seeked to (i.e. segments are -available for that position), we will try to play close to[2] that date.

    -
    • -
  • -

    if either we do not have a clock synchronization mechanism[1] or if we have -one but no segment is defined for the current date, we will play close to[2] -the maximum calculated position instead.

    -
    • -
  • -

    Third case, if we do not have any clock synchronization mechanism[1] and if -the Manifest does not announce clearly a maximum position, we will use the -system clock and play close to[2] that time instead.

    -
    • -
-

[1] We can obtain a synchronized clock allowing us to to know which content -should be broadcasted at which time by either of those means:

-
    -
  • the Manifest document defines one (e.g. UTCTiming elements for DASH -contents).
    • -
  • One was provided to loadVideo thanks to the serverSyncInfos transport -option see loadVideo -documentation.
    • -
-

[2] I wrote “close to” in every cases as we might substract some seconds from -that value. How much we might do, depends on:

-
    -
  • if the manifest suggest us a delay relative to the live, in which case we -apply it
    • -
  • if not, we set it to the default: 10 seconds
    • -
-

-

When no startAt option has been set and we’re playing a directfile content

-

For directfile contents, we for now just start at 0 if no startAt is -defined.

Terms and definitions

-

-

-

Overview

-

As the RxPlayer manages multiple type of streaming technologies, which can use -their own definition and terminology, we had to find a compromise and use our -own terminology, which try to take the best from these.

-

We here define various terms used in the documentation which might not be -obvious right along.

-

-

-

Definitions

-

-

-

Adaptation

-

Simply put, what we call an “Adaptation” is just an audio, video or text track.

-

More technically, it is an element of a Period (and by extension of -the Manifest) which represents a single type of media.

-

An adaptation can be for example any of those things:

-
    -
  • A video track
    • -
  • A french audio track
    • -
  • An italian text track
    • -
  • A thumbnail track
    • -
  • …
    • -
-

Many Streaming Technology have this concept even though their name can change, -an Adaptation is equivalent to:

-
    -
  • DASH’s AdaptationSet
    • -
  • Microsoft Smooth Streaming’s StreamIndex
    • -
-

Note: There is minor differences between the RxPlayer’s Adaptation and DASH’ -AdaptationSet. Namely multiple AdaptationSets can be merged into a single -Adaptation in very specific cases. -You can find more infos on it here.

-

-

-

Bitrate

-

In the RxPlayer, a bitrate of a Representation indicates the -number of bits per second of content described by that Representation.

-

For example, let’s imagine a video Adaptation with two -Representation:

-
    -
  1. one with a bitrate at 1,000,000 (which is 1 Megabit)
    2. -
  2. the other with a bitrate at 500,000 (which is 500 kilobits)
    3. -
-

Each seconds of content described by the first Representation will be -represented by 1 megabit of data

-

Each seconds for the second Representation will be represented by 500 kilobits.

-

Both will represent the same data, but the first one will need that the RxPlayer -fetch more data to show the same amount of content.

-

In most cases, a higher bitrate means a higher quality. That’s why the RxPlayer -has to compromise between having the best quality and choosing a Representation -having a low-enough bitrate to be able to play on the user’s computer without -needing to pause due to poor network conditions.

-

-

-

Buffer

-

When we talk about the “buffer” in the RxPlayer, we most likely refer to the -structures in the browser holding media data, waiting to be decoded.

-

Several layers of buffers can be defined in the browser-side to allow to have a -smooth playback, fast seeking etc.

-

-

-

Buffer type

-

RxPlayer’s buffer types describe a single “type” of media.

-

Example of such types are:

-
    -
  • “video”: which represents only the video content
    • -
  • “audio”: the audio content without the video
    • -
  • “text”: the subtitles, for example
    • -
-

-

-

Chunk

-

Depending on the context, a chunk can be either a sub-part of a Media -Segment or the Media segment itself.

-

-

-

Initialization segment

-

An initialization segment is a specific type of media segment, which -includes metadata necessary to initialize the browser’s internal decoder.

-

Those are sometimes needed before we can actually begin to push any “real” media -segment from the corresponding Representation.

-

As such, when one is needed, the initialization segment is the first segment -downloaded for a given Representation.

-

-

-

Manifest

-

The Manifest is the generic name for the document which describes the content -you want to play.

-

This is equivalent to the DASH’s Media Presentation Description (or MPD), -the Microsoft Smooth Streaming’s Manifest and the HLS’ Master Playlist.

-

Such document can describe for example:

-
    -
  • multiple qualities for the same video or audio tracks
    • -
  • multiple audio tracks in different languages
    • -
  • presence of subtitles
    • -
-

Note that this concept is only used in Streaming technologies. -You won’t interact with a Manifest if you’re directly playing a MP4 or webM -file.

-

-

-

Media segment

-

A media segment (or simply segment), is a small chunk of media data.

-

In many streaming technologies, a content is separated into multiple chunks of -small duration (usually between 2 and 10 seconds).

-

This allows, for reasons to long to detail here, to easily implements many -features:

-
    -
  • live streaming,
    • -
  • language switching
    • -
  • adaptive streaming
    • -
-

When you play a content with the RxPlayer, it will most of the time download -media segments of different types (audio, video, text…) progressively rather -than the whole content at a single time.

-

-

-

Period

-

Simply put, a Period defines what the content will be from a starting time to -an ending time. It is an element contained in the Manifest) and it -will contain the Adaptations available for the corresponding -time period.

-

Depending on the transport used, they correspond to different concepts:

-
    -
  • for DASH contents, it is more or less the same thing than an MPD’s -<Period> element
    • -
  • for “local” contents, it corresponds to a single object from the periods -array.
    • -
  • for “MetaPlaylist” contents, it corresponds to all the Period elements we -retrieved after parsing the corresponding Manifest from the -elements of the contents array.
    • -
  • any other transport will have a single Period, describing the whole content.
    • -
-

–

-

As an example, let’s take a manifest describing a live content with -chronologically:

-
    -
  1. an english TV Show
    2. -
  2. an old italian film with subtitles
    3. -
  3. an American blockbuster with closed captions.
    4. -
-

Let’s say that those sub-contents are drastically different:

-
    -
  • they are all in different languages
    • -
  • the american blockbuster has more available video bitrates than the old -italian one
    • -
-

Because the available tracks and available qualities are different from -sub-content to sub-content, we cannot just give a single list of Adaptations -valid for all of them. They have to be in some way separated in the Manifest -object.

-

That’s a case where Periods will be used. -Here is a visual representation of how the Periods would be divided here:

-
        Period 1                Period 2                Period 3
-08h05              09h00                       10h30                 now
-  |==================|===========================|====================|
-        TV Show               Italian Film        American Blockbuster
-
-

Each of these Periods will be linked to different audio, video and text -Adaptations, themselves linked to different Representations.

-

-

-

Representation

-

A Representation is an element of an Adaptation, and by extension -of the Manifest) that describes an interchangeable way to represent -the parent Adaptation.

-

For example, a video Adaptation can have several Representations, each having -its own bitrate, its own width or its own height. -The idea behind a Representation is that it can be changed by any other one in -the same Adaptation as the content plays.

-

This is most often implemented to allow multiple bitrates for the same -Adaptation, to be more flexible to poor network (low bandwidth) or computing -(slow computer) conditions.

-

A Representation has its equivalent in multiple Streaming technologies. It is -roughly the same as:

-
    -
  • DASH’s Representation
    • -
  • Microsoft Smooth Streaming’s QualityIndex
    • -
  • HLS’ variant (the notion of variant is actually a little more complex, -so here it’s not an exact comparison)
    • -

Tutorial: Playing contents with DRMs

-

Because different applications and different devices can work completely -differently when it comes to DRM, and because it is a complex feature, we have -a large API allowing to manage it.

-

This tutorial page is specifically there to help you navigate through this API.

-

We will begin from the simplest of use cases to dive into the more complex ones.

-

We recommend you to read the quick start tutorial first if -you haven’t, to have a general grasp on how to basically run a content.

-

-

Playing a simple encrypted content

-

To be able to play a simple encrypted content, we will need at least two -parameters:

-
    -
  1. type: the name of the “key system” you want to use.
    2. -
  2. getLicense: the license-fetching logic
    3. -
-

This chapter will explain both and provide examples on how to load a video with -both of these properties.

-

-

The key system

-

The key system, also known as “DRM name”, will designate which Content -Decryption Module (or CDM) to use. You might have heard of “Widevine”, -“PlayReady” or “FairPlay”, that’s the name what we want to know: which system -you want to use.

-

Which of them you want to use depend on several factors, among which:

-
    -
  • what the content allows
    • -
  • what the content right holder wants
    • -
  • what you/your company wants
    • -
  • what the browser can do
    • -
-

In the RxPlayer’s API, we more especially expect the whole “reverse domain name” -for that key systems (e.g. com.widevine.alpha or com.microsoft.playready).

-

We also have shortcuts for Widevine or PlayReady, where you can just tell us -respectively widevine or playready as the key system and we will try -several corresponding reverse domain names.

-

In any case, you can ask for several key systems, even including ones that are -not available in the current browser. Those will be detected and automatically -filtered out.

-
rxPlayer.loadVideo({
-  // ...
-  keySystems: [
-    {
-      type: "com.widevine.alpha"
-      // ...
-    },
-    {
-      type: "com.microsoft.playready"
-      // ...
-    },
-  ]
-})
-
-

-

The license-fetching logic

-

The second needed argument is a callback allowing to fetch the content license.

-

An encrypted content will need one or several keys to be able to decrypt a -content. Those keys are contained in one or several license files.

-

Those files usually need to be downloaded from a license server.

-

As that logic sometimes depends on your application (i.e. you might want to -add authentification to that request to know which user made that request), the -RxPlayer team made the choice to let you write your logic entirely.

-

This logic takes the form of a callback named getLicense.

-

This function is in fact triggered everytime a message is sent by the Content -Decryption Module (what is sometimes known as “Widevine” or “PlayReady”), which -is usually a request to fetch or renew the license.

-

It gets two arguments when called:

-
    -
  1. message (Uint8Array): The “message”
    2. -
  2. messageType (string): String describing the type of message received. -There is only 4 possible message types, all defined in the w3c -specification.
    3. -
-

In most cases, this function is triggered for license requests. -You’re encouraged to read what the messageType can be, but don’t be scared by -it, you’ll most likely never need to check it.

-

What you will most likely need to do, is simply sending the first argument, -message, to the license server to fetch the license. That message generally -contains information about the license you want to fetch.

-

You will then need to return a Promise, which resolves with the license in an -ArrayBuffer or Uint8Array form. -If you don’t want to communicate a license based on this message, you can just -return null or a Promise resolving with null.

-

Here is an example of a valid and simple getLicense implementation:

-
function getLicense(challenge) {
-  return new Promise((resolve, reject) => {
-    const xhr = new XMLHttpRequest();
-    xhr.open("POST", LICENSE_SERVER_URL, true);
-    xhr.onerror = (err) => {
-      reject(err);
-    };
-    xhr.onload = (evt) => {
-      if (xhr.status >= 200 && xhr.status < 300) {
-        const license = evt.target.response;
-        resolve(license);
-      } else {
-        const error = new Error("getLicense's request finished with a " +
-                                `${xhr.status} HTTP error`);
-        reject(error);
-      }
-    };
-    xhr.responseType = "arraybuffer";
-    xhr.send(challenge);
-  });
-}
-
-

-

Example with both properties

-

Now that all that has been explained here’s an example to play a simple -encrypted DASH content with either PlayReady or Widevine.

-
// We will use the same logic for both PlayReady and Widevine
-function getLicense(challenge) {
-  return new Promise((resolve, reject) => {
-    const xhr = new XMLHttpRequest();
-    xhr.open("POST", LICENSE_SERVER_URL, true);
-    xhr.onerror = (err) => {
-      reject(err);
-    };
-    xhr.onload = (evt) => {
-      if (xhr.status >= 200 && xhr.status < 300) {
-        const license = evt.target.response;
-        resolve(license);
-      } else {
-        const error = new Error("getLicense's request finished with a " +
-                                `${xhr.status} HTTP error`);
-        reject(error);
-      }
-    };
-    xhr.responseType = "arraybuffer";
-    xhr.send(challenge);
-  });
-}
-
-rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-    },
-    {
-      type: "playready",
-      getLicense,
-    }
-  ]
-});
-
-

This code is sufficient for a majority of encrypted contents.

-

-

More control over the license-fetching logic

-

There’s a lot of things that can go wrong during the license request:

-
    -
  • The user could be temporarly disconnected
    • -
  • The license server might be down
    • -
  • The license server might refuse to deliver a license based on your rights
    • -
  • The license server might refuse to deliver a license based on your CDM -capabilities
    • -
  • And like any request a lot of other errors can happen
    • -
-

From this, you could want to have a different behavior based on what happened:

-
    -
  • When a user is temporarly disconnected, you could chose to retry -indefinitely (the RxPlayer retry after a delay to not overload the client or -the server).
    • -
  • When the license server is down, you might want to fail directly.
    • -
  • When the license server refuse to deliver a license based on your rights, -you might want to throw an explicit error message that you will be able to -display.
    • -
  • If there’s a problem with your CDM capabilities, you might want to just -fallback to another media quality with a different license.
    • -
-

All of this is possible with more advanced APIs that we will see in this -chapter.

-

-

getLicenseConfig

-

getLicenseConfig is an object allowing to configure two parameters:

-
    -
  • -

    retry, which will set the maximum number of retry. -When setting 1, for example, we will try two times the request: A first -original time and one retry.

    -

    You can decide to by default retry indefinitely by setting it to Infinity -(yes, that’s a valid number in JS and some other -languages). Don’t worry, you will -still be able to retry less time on some other events (explained in -the getLicense error configuration chapter).

    -
    • -
  • -

    timeout, which is the maximum time in milliseconds the RxPlayer will wait -until it considers a getLicense call to have failed. -By default it is set to 10000 (10 seconds). You can set it to -1 to -disable any timeout.

    -
    • -
-

For example, for infinite retry and no timeout, you can set:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      getLicenseConfig: {
-        retry: Infinity,
-        timeout: -1,
-      },
-    },
-    // ...
-  ]
-});
-
-

-

getLicense error configuration

-

getLicenseConfig handle general configurations about every getLicense calls, -but you can also have more specific configuration when a specific license -request fails.

-

This is done thanks to the rejected Promise returned by getLicense. -You can reject an error (or just an object), with the following properties:

-
    -
  • -

    noRetry: when set to true, the getLicense call will not be retried.

    -
    • -
  • -

    message: a custom message string we will communicate through a warning or -error event (depending if we will retry or not the call)

    -
    • -
  • -

    fallbackOnLastTry: When set to true and if we are doing or last -try or retry (to be sure you can set noRetry to true), we will try to -fallback to another quality, which might have a different license.

    -

    This is only useful for contents which have a different license depending on -the quality (for example having different rights for 4k video content than -for 480p video content). It is also only useful if the license server can -refuse to deliver a license for a particular quality but accept for another -quality.

    -
    • -
-

Here is an example showcasing all of those properties:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense(challenge) {
-        return new Promise((resolve, reject) => {
-          const xhr = new XMLHttpRequest();
-          xhr.open("POST", LICENSE_SERVER_URL, true);
-          xhr.onerror = (err) => {
-            // Keep retrying on XHR errors.
-            // Instanciating an Error like that automatically set the
-            // message attribute to this Error's message. That way, the
-            // linked "error" or "warning" event sent by the RxPlayer
-            // will have the same message.
-            const error = new Error("Request error: " + err.toString())
-            reject(err);
-          };
-          xhr.onload = (evt) => {
-            if (xhr.status >= 200 && xhr.status < 300) {
-              const license = evt.target.response;
-              resolve(license);
-            } else if (xhr.status >= 500 && xhr.status < 600) {
-              // Directly fails + fallbacks on a server error
-              const error = new Error("The license server had a problem and" +
-                                      ` responded with ${xhr.status} HTTP ` +
-                                      "error. We will now fallback to another" +
-                                      "quality.");
-              error.noRetry = true;
-              error.fallbackOnLastTry = true;
-              reject(error);
-            } else {
-              // else continue to retry
-              const error = new Error("getLicense's request finished with a " +
-                                      `${xhr.status} HTTP error`);
-              reject(error);
-            }
-          };
-          xhr.responseType = "arraybuffer";
-          xhr.send(challenge);
-        });
-      },
-      getLicenseConfig: {
-        retry: Infinity,
-        timeout: -1,
-      },
-    },
-    // ...
-  ]
-});

Contents with multiple keys

-

-

Why and how

-

One of the issues arising with DRM is that not all devices, Operating systems or -web browsers can provide a high level of guarantee that a content will be -protected against unauthorized usages (such as illegal copy). -In other words, some devices, OS or browsers might provide more guarantees than -other.

-

That’s the main reason why there’s sometime a compromise to have between -accessibility of a content (the number of the people able to view it) and this -guarantee.

-

To be able to provide the best of both worlds, a content right holder might ask -for a higher protection guarantee for higher video qualities.

-

For example, it might ask that a 4k video content of a given film should be much -harder to “pirate” than the 240p version of the same film. -In return, the 240p version can be watched by a lot more people on a lot of -different devices.

-

To achieve that, one of the solution on the content-side is to have different -decryption keys depending on the quality chosen. -There’s then two main strategies:

-
    -
  1. -

    Every keys are in the same license. A player will thus do only one -license request for the whole content and the keys inside will be -individually refused or accepted.

    -
    2. -
  2. -

    There is one or several keys per licenses, in several licenses. That way, -a player might ask a different license when switching the current -quality.

    -
    3. -
-

There’s pros and cons to both, but let’s not go too far into that!

-

Let’s start from the principle that our content is under one of those two cases -here and let’s find out what we have to do to handle it.

-

-

The strategy adopted by the RxPlayer

-

When playing a content, the RxPlayer by default stops and throws an error as -soon as either a key is refused or as the license fetching logic (the -getLicense function) fails (after enough retries).

-

When playing a content with multiple keys, you might instead not care that much -if a key is refused or if the license-fetching logic fails. -What you can just do is to remove the quality for which we could not obtain a -key and to instead fallback on another, decipherable, quality.

-

That’s exactly what the RxPlayer does, when the right options are set:

-
    -
  1. -

    when it detects a quality to be un-decipherable, it first emit a -decipherabilityUpdate event through its API, to signal to an application -which qualities have been blacklisted.

    -
    2. -
  2. -

    it automatically removes from the current media buffer the data linked to -the un-decipherable quality and put it in a black list: we will not load -this quality for the current content anymore.

    -
    3. -
  3. -

    it switches to another, hopefully decipherable, quality.

    -
    4. -
-

Let’s now talk about the API.

-

-

fallbackOnLastTry

-

This option was already explained in a previous chapter. Basically, it is a -boolean you can set to true when rejecting an error from the getLicense -callback. When set and if it was the last getLicense try or retry, the -RxPlayer will stop to play every quality sharing the same “protection -initialization data”. -What that last part really means is a little complex, but it generally means -that every qualities sharing the same license file will be considered as -un-decipherable.

-

For more information and an example on how to use it, you can go back on the -concerned previous part of this tutorial.

-

Please note that this option does not concern every errors linked to a refused -key. It only concerns issues when the license server refuse to deliver a -license. -On most cases you will also need the API documented in the next part, -fallbackOn.

-

-

fallbackOn

-

Where fallbackOnLastTry really is about the failure of a license request, the -fallbackOn is about the refused keys themselves.

-

As an example, the Content Decryption Module in the browser might decide that -your current device cannot provide a high enough guarantee that the content -cannot be copied. It might thus refuse to use one of the decryption key found in -a license, especially the one needed for the higher content qualities.

-

The fallbackOn object allows to fallback when this happens. -There is two possible sub-properties in it:

-
    -
  • keyInternalError: fallback when the corresponding key has the -status -"internal-error". We found that most widevine implementation use -this error when a key is refused.
    • -
  • keyOutputRestricted: fallback when the corresponding key has the -status -"output-restricted". This is the proper status for a key refused due -to output restrictions.
    • -
-

Both are booleans, and for the moment we recommend to set both to true in most -cases.

-

For people on embedded devices with specific key systems, you can look a little -more into what MediaKeyStatus -is set when a key is refused, and just set one of both.

-

Here is an example:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      fallbackOn: {
-        keyInternalError: true,
-        keyOutputRestricted: true,
-      }
-    },
-  ]
-});
-
-

-

decipherabilityUpdate event

-

When the RxPlayer detects a quality to be un-decipherable (which can only -happens when one of the properties explained here is set), it sends a -decipherabilityUpdate event.

-

This event allows an application to know that some key or license could not be -used by the RxPlayer.

-

The application could then infer that other contents from the same right holders -will have the same issues. -In that case, an optimization is possible by using the representationFilter -API which is part of the transportOptions loadVideo option, documented -here. By using this API, -we can filter out un-decipherable quality to avoid downloading them in the -first place.

-

-

Server certificate

-

The “server Certificate” is a certificate allowing to encrypt messages coming -from the Content Decryption module to the license server. They can be required -by some key system as a supplementary security mechanism.

-

Thankfully, an application is not obligated to set one, even if one is needed. -If not set, the Content Decryption Module will download it itself by using the -same route than a license request (the getLicense callback will be called).

-

This means however, that we have to perform two round-trips to the license -server instead of one:

-
    -
  1. one to fetch the “server certificate”.
    2. -
  2. the other to fetch the license.
    3. -
-

To avoid the first round-trip, it is possible for an application to directly -indicate what the serverCertificate is when calling loadVideo.

-

This is done through the serverCertificate property, in keySystems:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      serverCertificate,
-    },
-  ]
-});
-
-

The serverCertificate has to either be in an ArrayBuffer form or a -TypedArray (i.e. Uint8Array, Uint16Array etc.)

-

-

Persistent licenses

-

A persistent license allows to store a license for it to be available even when -a user quits the current page or restarts its computer. It can be used even if -the user is offline.

-

After loading a persistent license, it is automatically stored on the browser’s -side, but the RxPlayer still has to store an ID to be able to retrieve the right -session when reloading the same content later. -Because of that, persistent-license management comes in two part in the RxPlayer -API (as usual here, those should be set in keySystems):

-
    -
  1. -

    You’ll have to set the persistentLicense boolean to true

    -
    2. -
  2. -

    You’ll have to provide a license storage mechanism and set it as the -licenseStorage property.

    -
    3. -
-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      persistentLicense: true,
-      licenseStorage,
-    },
-  ]
-});
-
-

-

licenseStorage property

-

The licenseStorage property is an object allowing the RxPlayer to load and -saved stored IDs.

-

It needs to contain two functions:

-
    -
  • save: Which sould store the argument given. The argument will be an array -of Objects.
    • -
  • load: Called without any argument, it has to return what was given to the -last save call. Any return value which is not an Array will be ignored -(example: when save has never been called).
    • -
-

This API can very simply be implemented with the -localStorage -browser API:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      persistentLicense: true,
-      licenseStorage: {
-        save(data) {
-          localStorage.setItem("RxPlayer-licenseStorage", JSON.stringify(data));
-        },
-        load() {
-          const item = localStorage.getItem("RxPlayer-licenseStorage");
-          return item === null ? [] :
-                                 JSON.parse(item);
-        }
-      },
-    },
-  ]
-});
-
-

Do not be scared about security implications, the data saved is not secret and -does not help to identify a user.

-

You can also use every storage API at your disposition (some embedded devices -might have their own).

-

As a nice bonus, you can note that the data given is perfectly “serializable” -through the JSON.stringify browser API. This means that, as the example shown -above, you can call JSON.stringify on that data and retrieve it through a -JSON.parse call.

-

This is very useful for storage APIs which cannot store JavaScript objects.

-

-

Playback issues related to DRMs

-

The configuration example which finishes the last chapter should work in most -cases, but you might encounter very specific issues on some devices.

-

-

Issues with fallbacking with the Edge browser and PlayReady

-

We sometimes encountered a bug which makes the player loads indefinitely when -fallbacking from an undecipherable quality, if done through the -fallbackOnLastTry option. This was only constated on the Edge browser and -appears to be a browser or CDM bug.

-

Sadly, no work-around has been found for now for this issue. We’re currently -trying to create a reproducible scenario and document that issue so it can -hopefully be fixed in the future. In the meantime, you’re encouraged either to -use Widevine (only on Chromium-based Edge) or to not make use of the -fallBackOnLastTry option on that browser.

-

-

The Player do not download any segment when playing encrypted contents

-

This is probably due to an issue we encountered several time on embedded -devices.

-

Basically, this behavior is due to a deadlock, where the RxPlayer is waiting for -the CDM logic to be initialized to download segments but the CDM logic wait for -the opposite: it will only initialize itself once segments have been downloaded.

-

The RxPlayer is waiting for the CDM initialization for a very specific usage: -playing a mix of unencrypted and encrypted data. We detected that on some Chrome -versions we could not play encrypted data if we first played unencrypted data -without the CDM logic in place.

-

Fortunately, this usage is for very specific cases and you most likely won’t -need it (or even if you will, you most likely will not encounter that problem).

-

You can completely remove that deadlock with a property called -disableMediaKeysAttachmentLock. Like other properties introduced here, you -should put it in the keySystems object of loadVideo, like such:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      disableMediaKeysAttachmentLock: true,
-    },
-    {
-      type: "playready",
-      getLicense,
-      disableMediaKeysAttachmentLock: true,
-    }
-  ]
-});
-
-

-

After two or several loadVideo calls the RxPlayer refuses to play

-

There’s a chance that you’re encountering another issue we found on embedded -devices.

-

By default, the RxPlayer maintains a cache containing the last loaded licenses. -This allows to quickly switch to already-played contents, an important -improvement when playing live contents for example. -Rest assured, our cache size is not infinite, and as such it should work on most -devices.

-

However, we found that on some devices, this logic can be problematic, and it -will just refuse to add a license at a given point.

-

You can add a property which will flush that cache anytime the content changes, -called closeSessionsOnStop.

-

Like other properties introduced here, you should put it in the keySystems -object of loadVideo, like such:

-
rxPlayer.loadVideo({
-  url: MANIFEST_URL,
-  transport: "dash",
-  keySystems: [
-    {
-      type: "widevine",
-      getLicense,
-      closeSessionsOnStop: true,
-    },
-    {
-      type: "playready",
-      getLicense,
-      closeSessionsOnStop: true,
-    }
-  ]
-});

Tutorial: Quick Start

-

Because the RxPlayer exports a lot of functionnalities, you might want to -quickly test basic use cases before you dive deep into the whole API -documentation.

-

We will here learn how to simply load a video and to react to basic events.

-

-

Instanciating a Player

-

The first step is to instanciate a new RxPlayer.

-

Each RxPlayer instance is attached to a single video (or audio) HTML element, -and is able to play a single content at once.

-

To instanciate it with a linked video element you can just do something along -the lines of:

-
import RxPlayer from "rx-player";
-
-const videoElement = document.querySelector("video");
-const player = new RxPlayer({ videoElement });
-
-

videoElement is an RxPlayer option and will be the HTMLElement the RxPlayer -will load your media on.

-

Despite its name, you can also give it an <audio> element. It will still be -able to play an audio content without issue.

-

When you are ready to make use of more advanced features, you can look at the -other possible options in the Player Options page.

-

-

Loading a content

-

The next logical step is to load a content (audio, video or both).

-

Loading a new content is done through the loadVideo method.

-

loadVideo takes an object as arguments. There is here also a lot of -possible options, but to simplify we will start -with just three:

-
    -
  • -

    transport: String describing the transport protocol (can be "dash", -"smooth" or "directfile" for now).

    -
    • -
  • -

    url: URL to the content (to the Manifest for Smooth contents, to the MPD -for DASH contents or to the whole file for DirectFile contents).

    -
    • -
  • -

    autoPlay: Boolean indicating if you want the content to automatically -begin to play once loaded. false by default (which means, the player -will not begin to play on its own).

    -

Here is a quick example which will load and play a DASH content:

-
player.loadVideo({
-  url: "http://vm2.dashif.org/livesim-dev/segtimeline_1/testpic_6s/Manifest.mpd",
-  transport: "dash",
-  autoPlay: true,
-});
-
-

-

Reacting to basic events

-

Now that we are loading a content, we might want to know:

-
    -
  • if it succeed
    • -
  • if it failed
    • -
  • when we are able to interact with the content
    • -
-

To do all three of those things, you will need to listen to player events. -This is done through the addEventListener -method.

-

This method works the same way than the native one you might already use on -HTML elements.

-

For example, to know if a fatal error happened (this is an error which -interrupted the playback of the current content), you will just have to do:

-
player.addEventListener("error", (err) => {
-  console.log("the content stopped with the following error", err);
-});
-
-

And to know if the player successfully loaded a content and if you can now -interact with it, you can just do:

-
player.addEventListener("playerStateChange", (state) => {
-  if (state === "LOADED") {
-    console.log("the content is loaded");
-    // interact with the content...
-  }
-});
-
-

There is multiple other events, all documented in the events documentation -.

-

As the state is a central focus of our API, we also heavily documented states in -the player states documentation.

-

-

Interacting with the player

-

We’re now ready to interact with the current content.

-

There is a huge list of APIs you can use. -Some are useful only when a content is currently loaded (like play, -pause, seekTo or setAudioTrack) and others can be used in any case -(like setVolume, getVideoElement or loadVideo).

-

Here is a complete example where I:

-
    -
  1. Instanciate an RxPlayer
    2. -
  2. load a content with it with autoPlay
    3. -
  3. toggle between play and pause once the content is loaded and the user click -on the video element.
    4. -
-
import RxPlayer from "rx-player";
-
-// take the first video element on the page
-const videoElement = document.querySelector("video");
-
-const player = new RxPlayer({ videoElement });
-
-player.addEventListener("error", (err) => {
-  console.log("the content stopped with the following error", err);
-});
-
-player.addEventListener("playerStateChange", (state) => {
-  if (state === "LOADED") {
-    console.log("the content is loaded");
-
-    // toggle between play and pause when the user clicks on the video
-    videoElement.onclick = function() {
-      if (player.getPlayerState() === "PLAYING") {
-        player.pause();
-      } else {
-        player.play();
-      }
-    };
-  }
-});
-
-player.loadVideo({
-  url: "http://vm2.dashif.org/livesim-dev/segtimeline_1/testpic_6s/Manifest.mpd",
-  transport: "dash",
-  autoPlay: true,
-});
-
-

-

And now?

-

Now that you know the basic RxPlayer APIs, you might want to dive deep into the -whole API documentation.

Tutorial: Listening to stream events

-

Some contents contain events a player will need to send at a particular point -in time. We call those in the RxPlayer “stream events”.

-

For example, stream events are often used jointly with ad-insertion, to allow a -player to notify when an user begin to see a particular ad.

-

Stream events are not only restrained to ad-related usages though. Any event -you want to synchronize with the played content can be inserted.

-

-

Event Formats understood by the RxPlayer

-

-

DASH EventStream elements

-

For now, the RxPlayer only make use of DASH’ EventStream elements.

-

Such elements are defined in a DASH MPD in the concerned Period. -Here is an example of such element in an MPD:

-
<?xml version="1.0" encoding="UTF-8"?>
-<MPD
-  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-  xmlns="urn:mpeg:dash:schema:mpd:2011"
-  xsi:schemaLocation="urn:mpeg:dash:schema:mpd:2011 DASH-MPD.xsd"
-  type="dynamic"
-  minimumUpdatePeriod="PT2S"
-  timeShiftBufferDepth="PT30M"
-  availabilityStartTime="2011-12-25T12:30:00"
-  minBufferTime="PT4S"
-  profiles="urn:mpeg:dash:profile:isoff-live:2011">
-
-    <Period id="1">
-      <EventStream schemeIdUri="urn:uuid:XYZY" timescale="1000" value="call">
-        <Event presentationTime="0" duration="10000" id="0">
-          1 800 10101010
-        </Event>
-        <Event presentationTime="20000" duration="10000" id="1">
-          1 800 10101011
-        </Event>
-        <Event presentationTime="40000" duration="10000" id="2">
-          1 800 10101012
-        </Event>
-        <Event presentationTime="60000" duration="10000" id="3">
-          1 800 10101013
-        </Event>
-      </EventStream>
-      <!-- ... -->
-    </Period>
-
-</MPD>
-
-

Here the <EventStream /> elements and its <Event /> children elements will -be parsed by the RxPlayer.

-

Each <Event /> element can then be sent through a single RxPlayer events.

-

-

How to listen to stream events

-

The RxPlayer notify of such events through the usual RxPlayer events.

-

As a reminder (or if you didn’t know), the RxPlayer can send a multitude of -events that can be listened to by the usage of the -addEventListener method.

-

The events related to stream events are:

-
    -
  • -

    "streamEvent": an event has just been reached.

    -
    • -
  • -

    "streamEventSkip": an event has been skipped over. This usually means -that a player seek operation resulted in the corresponds event being -“missed”.

    -
    • -
-

In any case, the corresponding event will be attached as a payload.

-

Example:

-
// listen to "streamEvent" events
-rxPlayer.addEventListener("streamEvent", (evt) => {
-  console.log("An event has been reached:", evt);
-});
-
-// listen to "streamEventSkip" events
-rxPlayer.addEventListener("streamEventSkip", (evt) => {
-  console.log("We just 'skipped' an event:", evt);
-});
-
-

-

The event format

-

Whether you’re listening to the "streamEvent" or the "streamEventSkip" -event, you will receive an object containing the corresponding event -information.

-

Here is an example of such events:

-
{
-  start: 10, // start time of the event, in seconds.
-             //
-             // It is always defined, as a number.
-             //
-             // A start at `10` here means that the event began when the player
-             // reached the position at 10 seconds.
-
-  end: 25, // Optional end time of the event, in seconds.
-           //
-           // It can be undefined or unset for events without any duration.
-           // A end at `25` here indicates that this event only last from the
-           // position at 10 seconds (the `start`) to the position at 25
-           // seconds, or an event with a duration of 15 seconds.
-           //
-           // If `end` is defined, you can be notified when the end of this
-           // event is reached by adding an `onExit` callback to that event
-           // (continue reading this tutorial for more information).
-
-  data: { // The event's data itself.
-
-    type: EVENT_TYPE, // String describing the source of the event.
-
-    value: EVENT_VALUE, // This property's format and content depends on the
-                        // `type` property. For example, when the type property
-                        // is set to "dash-event-stream", this value will be the
-                        // <Event /> element corresponding to that DASH event.
-  }
-}
-
-

As written in this example, the underlying format of the event itself will -depend on the source of the event. For example, an event generated from a DASH’s -<EventStream /> won’t be in the same format that an event generated from a -MP4’s emsg box.

-

You can know which current format is used by checking the value of the -data.type property.

-

For now, we only have one format: DASH EventStream elements, which will have a -data.type property equal to "dash-event-stream".

-

-

DASH EventStream elements

-

A DASH EventStream’s event will be parsed under the following format:

-
{
-  start: 10, // As usual, the event start time in seconds
-
-  end: 15, // optional end position of the event, in seconds.
-           // Can be not set or set to `undefined` for events without a duration
-
-  data: {
-
-    type: "dash-event-stream", // Type corresponding to a DASH's EventStream's
-                               // Event element
-
-    value: {
-      schemeIdUri: SCHEME_ID_URI,
-      element: EVENT_ELEMENT,
-      timescale: EVENT_TIMESCALE,
-    }
-  }
-}
-
-

Where:

-
    -
  • -

    SCHEME_ID_URI will be the value of the corresponding EventStream’s -schemeIdUri attribute

    -
    • -
  • -

    EVENT_ELEMENT will be the corresponding <Event /> element in the MPD.

    -
    • -
  • -

    EVENT_TIMESCALE will be the value of the corresponding EventStream’s -timescale attribute. -This indicates a way to convert some time information on an -EVENT_ELEMENT into seconds (by dividing the value by timescale), -though it can usually safely be ignored.

    -
    • -
-

For example for the following EventStream:

-
<EventStream schemeIdUri="urn:uuid:XYZY" timescale="1000" value="call">
-  <Event presentationTime="0" duration="10000" id="0">1 800 10101010</Event>
-  <Event presentationTime="40000" duration="10000" id="1">1 800 10101012</Event>
-  <Event presentationTime="60000" duration="10000" id="2">1 800 10101013</Event>
-</EventStream>
-
-

The RxPlayer will define those three events (note: I used custom syntax here to -include a readable document format):

-
// The first event:
-{
-  start: 0,
-  end: 10,
-  data: {
-    type: "dash-event-stream",
-    value: {
-      schemeIdUri: "urn::uuid::XYZY",
-      element: <Event presentationTime="0" duration="10000" id="0">
-                 1 800 10101010
-               </Event>,
-      timescale: 1000,
-    }
-  }
-}
-
-// The second event:
-{
-  start: 40,
-  end: 50,
-  data: {
-    type: "dash-event-stream",
-    value: {
-      schemeIdUri: "urn::uuid::XYZY",
-      element: <Event presentationTime="40000" duration="10000" id="1">
-                 1 800 10101012
-               </Event>,
-      timescale: 1000,
-    }
-  }
-}
-
-// The third event:
-{
-  start: 60,
-  end: 70,
-  data: {
-    type: "dash-event-stream",
-    value: {
-      schemeIdUri: "urn::uuid::XYZY",
-      element: <Event presentationTime="60000" duration="10000" id="2">
-                 1 800 10101013
-               </Event>,
-      timescale: 1000,
-    }
-  }
-}
-
-

-

Listening when an event has ended

-

Some stream events have a end property, you could thus need to know when an -event that the RxPlayer reached is now ended.

-

Thankfully, we planned this need in the API of the RxPlayer.

-

Any event with a set end can be added an onExit callback. This callback will -be called once the event has ended.

-

So for example you can write:

-
rxPlayer.addEventListener("streamEvent", (evt) => {
-  console.log("An event has been reached:", evt);
-  if (evt.end !== undefined) {
-    evt.onExit = () => {
-      console.log("An event has been exited:", evt);
-    }  ;
-  }
-});
-
-

When defined, that onExit callback will be called once the RxPlayer either -reaches the end position of the event or seek outside of the scope of this -event.

-

Please note however that even if an event has an end property, it is possible -that the onExit callback will never be called. For example, the user could -stop the content while an event was “active” (we do not trigger onExit -callbacks in that case) or the corresponding <Event /> could “disappear” from -the MPD once it has been refreshed.

-

-

Example

-

To end this tutorial, lets define a complete example:

-
rxPlayer.addEventListener("streamEvent", (evt) => {
-  console.log("An event has been reached:", evt);
-
-  console.log("This is an event of type:", evt.data.type)
-  if (evt.data.type === "dash-event-stream") {
-    console.log("This is a DASH EventStream's Event element.");
-
-    console.log("schemeIdUri:", evt.data.schemeIdUri);
-    console.log("<Event /> element:", evt.data.element);
-  }
-
-  if (evt.end !== undefined) {
-    evt.onExit = () => {
-      console.log("An event has been exited:", evt);
-    };
-  }
-});
-
-rxPlayer.addEventListener("streamEventSkip", (evt) => {
-  console.log("We just 'skipped' an event:", evt);
-
-  console.log("This was an event of type:", evt.data.type)
-  // ...
-});

Tutorial: Selecting a track

-

-

The goal of this tutorial

-

The RxPlayer has an advanced API when it comes to track selection:

-
    -
  • -

    You can list the available audio, video and/or text tracks and chose one of -them

    -
    • -
  • -

    You can disable the current video and / or text track

    -
    • -
  • -

    You can also give to the RxPlayer a set of preferences so it can make the -best choice by itself without manually having to choose the right track -for every contents.

    -

    Those preferences can even be applied retro-actively (for example, to the -content currently being played), depending on your need.

    -
    • -
-

Because the RxPlayer declares multiple APIs to allow those different use cases, -the track selection API can seem intimidating and confusing at first.

-

This tutorial will help you understand what your options are, why you would use -an API instead of another one and how to use them.

-

-

What is a “track”?

-

We should first agree on what is a track, as a concept.

-

Let’s take for example an italian film presented to an english-speaking -audience.

-

For that film, let’s imagine those multiple “audio tracks”:

-
    -
  • one being the original audio track, in italian
    • -
  • one being a dub in the english language
    • -
  • another in english with accessibility features such as an audio description -of what visually happens in the film (for example, to give cues of what is -happening to the visually-impaired).
    • -
-

There also could be multiple “text tracks”:

-
    -
  • subtitles in english
    • -
  • closed-captions in english (for example, for the hearing impaired)
    • -
-

And we could even imagine multiple video tracks:

-
    -
  • one displaying the “regular” film
    • -
  • another displaying either the same film from a different camera angle (seems -far-fetched here but let’s just pretend we’re talking about some kind of -experimental film!)
    • -
-

All those will provide to the user a different way to offer the same film. They -even can technically be switched one independently of the other (though -restrictions on possible combinations can exist) to give a large number of -different experience for what is effectively the same content.

-

-

Listing the available tracks

-

-

Preamble

-

The RxPlayer does not “guess” the tracks available for a given content. -It usually finds every information about them in a specific file, called the -Manifest.

-

Thus, the list of available tracks will only be available once the RxPlayer has -loaded and parsed that Manifest. -Moreover, a Manifest can have several lists of available tracks depending on the -player’s position (for example, a live channel with multiple programs might have -different audio languages available for different programs).

-

This means both that the available tracks won’t generally be known just after a -loadVideo call and that it can then change at any time.

-

Thankfully, most of this complexity is abstracted by the RxPlayer API.

-

-

Using methods

-

Once the RxPlayer has loaded the content (meaning the RxPlayer is not in the -STOPPED, LOADING or RELOADING player state) you can -begin to ask it what is the current list of available tracks.

-

This can be done through three RxPlayer methods:

- -

Those methods will all return arrays of objects, each object containing -information about a single track.

-

It should be noted that the information for an audio track won’t be the same -than for a video or a text track. -For example, you might be interested by the height and width available in a -video track. Those notions make absolutely no sense for an audio track.

-

For more information about the structure of the data returned by those methods, -you can refer to their API documentation (a shortcut is available by clicking -on the method name).

-

Note that you can still ask for the current tracks when the RxPlayer does not -have loaded any content (is in the STOPPED, LOADING or RELOADING player -state), but you will most likely only get an empty array in those cases.

-

Examples

-

Those methods are straightforward, here are some examples of how they can be -used:

-
// Array of all available audio languages
-const availableLanguages = rxPlayer.getAvailableAudioTracks()
-  .map(track => track.language);
-
-// List of audio tracks containing an audio description of what is visually
-// happening
-const audioDescriptionTracks = rxPlayer.getAvailableAudioTracks()
-  .filter(track => track.audioDescription);
-
-// List of video tracks for which a profile with a 1080p resolution is available
-const highResVideoTracks = rxPlayer.getAvailableVideoTracks()
-  .filter(track => {
-    return track.representations
-      .some(representation => representation.height !== undefined &&
-                              representation.height >= 1080);
-  });
-
-// List of text tracks available in french
-const frenchTextTracks = rxPlayer.getAvailableTextTracks()
-  .filter(track => track.normalized === "fra");
-
-

-

Using events

-

If you want to have the list of available tracks as soon as possible, it might -be a good idea to rely on the related events.

-

Here are the three events you will need to know:

- -

All of those events will have the corresponding available tracks as a payload, -which will be the exact same data that what you would get when calling the -corresponding getAvailable...Tracks method at this point.

-

Note that no available...TracksChange event will be sent when the RxPlayer -stops the content or temporarly goes through the RELOADING player state, -despite the fact that in those cases there is no available tracks to choose -from.

-

Still, calling the getAvailable...Tracks methods in those cases will return -an empty array (as it should). This has to be considered.

-

Examples

-

Like any RxPlayer event, you will need to add an event listener for those:

-
let currentAudioTracks = [];
-let currentVideoTracks = [];
-let currentTextTracks = [];
-
-rxPlayer.addEventListener("availableAudioTracksChange", audioTracks => {
-  console.log("New audio tracks:", audioTracks);
-  currentAudioTracks = audioTracks;
-})
-
-rxPlayer.addEventListener("availableVideoTracksChange", videoTracks => {
-  console.log("New video tracks:", videoTracks);
-  currentVideoTracks = videoTracks;
-})
-
-rxPlayer.addEventListener("availableTextTracksChange", textTracks => {
-  console.log("New text tracks:", textTracks);
-  currentTextTracks = textTracks;
-})
-
-

-

Should you use the methods or events?

-

Both the exposed methods and events return the same data.

-

Whether you should rely on the former or on the latter will depend on what -corresponds the most to your codebase:

-
    -
  • -

    if you want to fetch that list at a given point in time - such as when the -user clicks on a button - it can be easier to just call the methods.

    -
    • -
  • -

    if you want to know that list as soon as available and perform an action -right after (such as selecting a track, displaying this list…), you might -prefer relying on the events.

    -

    Here you will also have to re-set that list yourself when the player has no -content loaded anymore (in the STOPPED, LOADING or RELOADING player -state).

    -
    • -
-

-

Knowing the current track

-

You might also want to know which track is the one currently selected. -There are several ways to do that.

-

-

Through methods

-

The RxPlayer has a set of methods that just return the currently active tracks:

-
    -
  • -

    getAudioTrack: return information -on the current audio track

    -
    • -
  • -

    getVideoTrack: return information -on the current video track

    -
    • -
  • -

    getTextTrack: return information -on the current text track

    -
    • -
-

Those methods will return an object describing the attributes of the current -tracks. -They can also return null if no track has been enabled (for example, the user -could have wanted to disable all text tracks) and undefined if the track is -either unknown (which is a very rare occurence) or if no content is currently -playing.

-

Like the getAvailable...Tracks methods, the format of the objects returned -will entirely depend on which method you call. You can refer to the API -documentation to get more information on this.

-

Also like the getAvailable...Tracks methods, the current text track will -usually only be known once the RxPlayer has loaded a content (which means we are -not in the STOPPED, LOADING or RELOADING player -state). If no content is loaded, those APIs will just return -undefined.

-

Examples

-

Here is an example on how you could use them:

-
const currentTextTrack = rxPlayer.getTextTrack();
-if (currentTextTrack === null) {
-  console.log("No text track is enabled");
-} else if (currentTextTrack === undefined) {
-  console.log("We don't know the current text track. " +
-              "Are you sure a content is loaded?");
-} else {
-  const language = currentTextTrack.language;
-  console.log("We have a current text track in the " + language + "language");
-}
-
-

-

Through events

-

Exactly like you would obtain the list of available tracks through the -available...TracksChange events, you can know when the current track change as -soon as possible through the following events:

- -

Those events just emit the current track information as soon as it changes, in -the same format that the get...Track methods.

-

Unlike for the get...Track methods however, its payload cannot be set to -undefined: you won’t receive any ...TracksChange event if the track is -unknown or if there is no content.

-

This also means that you won’t have any event when the RxPlayer stops or -re-load the current content, despite the fact that you don’t have any current -track in that case. -Calling the get...Track method in those cases will return undefined, as it -should. This has to be considered.

-

Example

-

Like for any events, you will have to register an event listener:

-
rxPlayer.addEventListener("textTrackChange", track => {
-  if (track === null) {
-    console.log("No text track is active");
-  } else {
-    console.log("new active text track in the following language: " + track.language);
-  }
-});
-
-

-

Through the list of available tracks

-

As written earlier the available...TracksChange events and the -getAvailable...Tracks methods both return arrays of objects, each object -defining a single track.

-

In each of those object, you will find an active boolean property, which will -be set to true if the track is the currently chosen one and false otherwise.

-

Note that it’s possible that none of the available tracks are active. This is -for example the case when the track has been disabled (for example when the user -wants no text tracks at all).

-
// get the active audio track through `getAvailableAudioTracks`
-const activeAudioTrack1 = rxPlayer.getAvailableAudioTracks()
-  .find(track => track.active);
-
-// get the active audio track through `availableAudioTracksChange`
-let activeAudioTrack2;
-rxPlayer.addEventListener("availableAudioTracksChange", (tracks) => {
-  activeAudioTrack2 = tracks.find(track => track.active);
-});
-
-

-

Which one to use?

-

As usual here, this is highly dependant on your application. All of those APIs -give the same information through different means.

-

Accessing with the get...Track method is simple to use, the events allow to -know at the earliest possible time and relying on the list of available tracks -can simplify your code if you want both of them.

-

-

Selecting a track

-

Now that we have the list of available tracks and the current one, we might want -to choose another one, or let the final user choose another one.

-

To do that, you will have to use one of those three RxPlayer methods:

- -

Each of those methods take a single string as argument. That string should be -the value of the id property of the chosen track.

-

For example, to choose the first audio track with an audio description, you can -do:

-
const firstAudioTrackWithAD = rxPlayer.getAvailableAudioTracks()
-  .find(track => track.audioDescription);
-
-if (firstAudioTrackWithAD !== undefined) {
-  rxPlayer.setAudioTrack(firstAudioTrackWithAD.id);
-}
-
-

It’s important to consider that those APIs only allow to change the current -track and will have no impact on the other contents you will encounter in the -future.

-

Depending on your application, you might also want to set a global preference at -some point, such as saying that the final user will prefer english audio -tracks for now on.

-

Although setAudioTrack can be used for this use case - by just setting an -english audio track every times the available audio tracks list change (we can -know that through the availableAudioTracksChange event) - it is much more -efficient and less cumbersome to use audio track preference APIs for that. -Those will be described later in this tutorial, so stay with me!

-

After manually setting a track through the set...Track methods, you will -receive the corresponding ...TrackChange event when the change is applied.

-

Note that on some contents, changing a track from a given type might -automatically also change the current track for another types. For example, -switching to another audio language might also automatically turn on the -subtitles. This is because some streaming protocols might “force” some -combination.

-

To detect those cases, you can either listen to every ...TrackChange events -or call the corresponding get...Track method everytime you want to use them.

-

-

Disabling a track

-

Now what if you want no track at all?

-

This is for example a frequent need for text tracks, where you might prefer to -have no subtitles or closed captions appearing on the screen.

-

You could also want to disable the video track, which is a trick often used to -reduce the network bandwidth used by a content.

-

You can disable respectively the current text track and the current video track -by calling those methods:

- -

However, like for selecting a track, this only concerns the current content -being played. When playing a new content or even when just switching to another -part of the content with a different track list, you might need to re-do the -same method call.

-

This is problematic most-of-all when disabling the video track, as going in and -out of that usually requires a short but visible “re-loading” step by the -RxPlayer. You want thus to limit the need to call disableVideoTrack every -times a new content is encountered.

-

Thankfully, the RxPlayer has another set of API to let you choose a track even -for future contents: the “track preferences APIs”.

-

-

Track preferences APIs

-

All methods and events discussed until now only have an effect for the current -content being played.

-

This has multiple disadvantages:

-
    -
  • -

    that code has to be run each time a new content is loaded (and each time the -track list changes, if there are multiple track lists for a single -contents).

    -
    • -
  • -

    it is inefficient: -In some cases the RxPlayer pre-load new content to allow a smooth transition -between the current content and that new one. -To do that, it chooses a track itself and begin to download it.

    -

    If when reaching the new content a totally other track is finally chosen, -we might have wasted network bandwidth for nothing as we would have to -re-download a completely different track.

    -

    Even more important, the transition won’t be smooth at all because we -will have to stop to build some buffer with the wanted track instead.

    -
    • -
-

Thankfully, there exists another set of APIs we call the “track preferences”.

-

With those, you can tell the RxPlayer that you might always prefer the audio -track to be in english - for example - or that you would prefer the video track -to be in a given codec.

-

Bear in mind that track preferences APIs are for a different use case than the -classic track selection APIs:

-
    -
  • -

    the “classic” track selection APIs are here to select a precize track -amongst available ones.

    -

    This is probably the APIs you will use when displaying a list of available -tracks to the final user and choosing one.

    -
    • -
  • -

    the track preferences APIs give hints of what the finally user generally -wants, so that the right track is automatically chosen by the RxPlayer. It -is also useful for optimizations such as when pre-loading the next content.

    -

    This is the APIs you will use in most other use cases, where you want to -give the general track settings the user wants to the RxPlayer.

    -
    • -
-

The track preferences can be set in two manners:

-
    -
  1. During instanciation of the RxPlayer
    2. -
  2. At any time, through specific methods
    3. -
-

-

Setting a track preference on instanciation

-

There are three options you can give to the RxPlayer on instanciation to set the -track preferences:

- -

You can click on the name of the option to be redirected to its corresponding -API documentation.

-

Each of those take an array of object which will define which track you want the -RxPlayer to choose by default.

-

As a simple example, to choose french audio tracks without audio description by -default you could do:

-
const rxPlayer = new RxPlayer({
-  preferredAudioTracks: [{ language: "fra", audioDescription: false }],
-});
-
-

Because not all contents could have a track matching that preferences, you can -add even more elements in that array. For example, if you want to fallback to -english if no french audio track is found you can do:

-
const rxPlayer = new RxPlayer({
-  preferredAudioTracks: [
-    { language: "fra", audioDescription: false },
-    { language: "eng", audioDescription: false },
-  ],
-});
-
-

Here, the RxPlayer will enable a french audio track if it finds one, but if it -does not, it will enable the english one instead.

-

If none of your preferences is found for a given content, the RxPlayer will -choose the content’s default (or first, if no default is announced in the -content) track itself.

-

Those options allow much more powerful configurations. You can refer to the API -documentation for that.

-

-

track preferences methods

-

You can also update at any time those track preferences - even when no content -is playing - by calling the following methods: -- setPreferredAudioTracks: -update the audio preferences -- setPreferredTextTracks -update the text preferences -- setPreferredVideoTracks -update the video preferences

-

Those methods mostly work the same way than the constructor options. You give -them an array of the wanted track configurations and the RxPlayer will try to -choose a track that match with the earliest possible configuration in that -array:

-
rxPlayer.setPreferredAudioTracks([
-  { language: "fra", audioDescription: false },
-  { language: "eng", audioDescription: false },
-]);
-
-

But there’s another element to consider here. -When calling the method (unlike when giving an option to the constructor), the -RxPlayer may already be playing a content. So here, there’s a dilemma:

-
    -
  • -

    should the RxPlayer apply the new preferences to the current content? It -could, but it might be unexpected if a track chosen explicitely by the user -for the current content changes because it does not match the preferences.

    -
    • -
  • -

    or should the RxPlayer only apply it to new contents? In that case, it could -also be an unexpected behavior. -Especially for contents with multiple track lists - here you could inversely -want your new preferences to be considered when seeking back to an -already-played content.

    -
    • -
-

There’s no good answer here, it all depends on the implementation you want to -do.

-

Because of that, those methods all can take a boolean as a second argument. -When this second argument is set to true, the RxPlayer will also apply that -preference to the already-loaded content:

-
// disable the text tracks from every contents - the current one included
-rxPlayer.setPreferredTextTracks([null], true);
-
-

If not set or set to false, it will only be applied for content that have not -been loaded yet.

-
// Only disable the text tracks from the next encountered contents.
-rxPlayer.setPreferredTextTracks([null]);
-
-

-

Obtaining the last set preferences

-

The RxPlayer also has three methods which will return the last set preferences:

- -

The format of the returned array will be the exact same than the array given to -the corresponding setPreferred...Tracks method (or the value of the -preferred...Tracks constructor option if the method was never called - or -just an empty array by default when neither was used).

-

-

What set of APIs should you use

-

The “classic” track selection APIs (getAvailable...Tracks, get...Track and -set...Track) are the APIs you should use when explicitely exposing the current -available tracks and selecting one precizely.

-

The track preferences APIs should be used for anything else.

-

This is because the track preferences APIs allow to completely move the task -of selecting a track out of your code and into the RxPlayer and will allow -some optimizations to take place.

-

The “classic” track selection APIs still allow to make a much more precize -choice and allow to know which tracks are currently available. -Due to that, they are a perfect fit when you want to propose a track choice menu -to the final user.

-

-

Notes about the “textTrackMode” option

-

This tutorial was focused on track selection but there’s still a last point I -want to approach, which is how subtitles will be displayed to the user.

-

By default, text tracks will be displayed through <tracks> elements which -will be contained in the media element where the content plays. -This allows to display subtitles but may not be sufficient when wanting to -display richer subtitles (such as closed-captions).

-

This is why the RxPlayer has a -textTrackMode concept.

-

By setting the textTrackMode to "html" in a -loadVideo call, you will be able to profit -from much richer subtitles than what you could have by default. -If you do that, you also need to set the -textTrackElement property -to an HTML element, that the RxPlayer will use to display subtitles into.

-

More information on those options can be found in the RxPlayer API.

Switching from version 2.x.x to 3.x.x

-

The 3.0.0 release brought multiple breaking changes that may impact your -codebase if you were based on a 2.x.x version (or inferior) previously.

-

Those breaking changes are mainly here to bring new features and simplify the -player maintenance. This file enumerates each one of those changes and propose -alternatives.

-

The simplest way of switching here would be to:

-
    -
  1. Check the General changes chapter
    2. -
  2. Check the constructor options you use (constructor options chapter)
    3. -
  3. Check the way you use the loadVideo method (loadVideo chapter)
    4. -
  4. Replace every method listed in the Removed methods chapter you use in -your codebase
    5. -
  5. Make sure that the methods listed in the Changed methods chapter are -correctly used now
    6. -
  6. Replace events listed in Removed events
    7. -
  7. Check events you use listed in Changed events
    8. -
-

If you were only using documented APIs and you follow this, you’ll be ready to -completely switch to a 3.x.x release !

-

If you don’t know if you were using documented APIs, you can still check if the -options, methods and events you use now are documented in the new -API. Now, most non-documented (private) APIs begin by the -string _priv_, to simplify this process.

General Changes

-

-

-

Features disabled by default

-

What Changed

-

Two features, previously activated by default, are now disabled by default.

-

Those features are:

-
    -
  1. The automatic limitation of the video track to filter those with a width -superior to the current video element’s width.
    2. -
  2. The automatic throttle on the audio and video bitrates set when the page is -hidden for more than one minute.
    3. -
-

If you want to activate the feature 1, you have to set the limitVideoWidth -boolean to true in the constructor’s option. For the feature 2, it is the -throttleWhenHidden constructor’s option you will have to set to true.

-

If you had set them to false to disable them before, you can now safely -remove those options from the constructor argument.

-

If you don’t know what to do with them, you might want to disable both features -(by not setting them on the constructor). They only are optimizations for -specific usecases.

-

Examples

-
// In the previous version
-player = new RxPlayer();
-
-// becomes
-player = new RxPlayer({
-  limitVideoWidth: true,
-  throttleWhenHidden: true
-});
-
-
// In the previous version
-player = new RxPlayer({
-  limitVideoWidth: false,
-  throttleWhenHidden: false
-});
-
-// becomes
-player = new RxPlayer();
-
-

-

-

Normalized language codes

-

What Changed

-

Previously, every language set in the manifest went through a translation step -to be translated into an ISO 639-2 language code.

-

This led the following APIs:

-
    -
  • getAvailableAudioTracks
    • -
  • getAvailableTextTracks
    • -
  • getAudioTrack
    • -
  • getTextTrack
    • -
  • getManifest
    • -
  • getCurrentAdaptations
    • -
-

To not reflect exactly the language as set in the manifest (just one of the ISO -639-2 translation of it). For example, "fra" was translated to "fre" -(even though both are valid ISO 639-2 language codes for the same language).

-

Because this behavior hide the true language value and ISO 639-2 language codes -have synonyms, we decided to:

-
    -
  1. switch to ISO 639-3 language codes instead. This standard has more -languages and does not have synonyms.
    2. -
  2. keep both the information of what is set in the manifest and the result of -our ISO 639-3 translation in two different properties
    3. -
-

Now, the tracks returned by:

-
    -
  • getAvailableAudioTracks
    • -
  • getAvailableTextTracks
    • -
  • getAudioTrack
    • -
  • getTextTrack
    • -
-

Will:

-
    -
  1. keep the language property, though this time it is the exact same one -than set in the manifest
    2. -
  2. will also have a normalized property, which is the ISO 639-3 -translation attempt. If the translation attempt fails (no corresponding ISO -639-3 language code is found), normalized will equal the value of -language.
    3. -
-

Likewise for the adaptations with a language set returned by:

-
    -
  • getManifest
    • -
  • getCurrentAdaptations
    • -
-

They will have both a language and a normalizedLanguage property, which -follow the same rule.

-

Difference between the previous and new language codes used

-

In most cases, if you were manually checking language codes in your codebase you -could just replace here the key language with its normalized counterpart -(either normalized or normalizedLanguage depending on the API you’re -using, see previous chapter).

-

However, while switching from ISO 639-2 to ISO 639-3, some language codes have -changed (all were synonyms in ISO 639-2):

-
    -
  • "alb" became "sqi" (for Albanian)
    • -
  • "arm" became "hye" (for Armenian)
    • -
  • "baq" became "eus" (for Basque)
    • -
  • "bur" became "mya" (for Burmese)
    • -
  • "chi" became "zho" (for Chinese)
    • -
  • "dut" became "nld" (for Dutch, Flemish)
    • -
  • "fre" became "fra" (for French)
    • -
  • "geo" became "kat" (for Georgian)
    • -
  • "ice" became "isl" (for Icelandic)
    • -
  • "mac" became "mkd" (for Macedonian)
    • -
  • "mao" became "mri" (for Maori)
    • -
  • "may" became "msa" (for Malay)
    • -
-

Example

-
console.log(player.getAvailableAudioTrack());
-
-// For a manifest with two audiotracks: "fr" and "en" without audio description
-
-// -- in the old version --:
-const oldVersionResult = [
-  {
-    language: "fre", // translated from "fr"
-    audioDescription: false,
-    id: "audio_1"
-  },
-  {
-    language: "eng", // translated from "en"
-    audioDescription: false,
-    id: "audio_2"
-  }
-];
-
-// -- became --:
-const result = [
-  {
-    language: "fr", // stays the same than in the manifest
-    normalized: "fra", // translated from "fr"
-                       // (notice that it's not "fre" like before)
-    audioDescription: false,
-    id: "audio_1"
-  },
-  {
-    language: "en", // stays the same than in the manifest
-    normalized: "eng", // translated from "en"
-    audioDescription: false,
-    id: "audio_2"
-  }
-];
-
-

-

-

Constructor options

-

-

-

defaultLanguage

-

What changed

-

This option has been removed from the constructor to simplify the API. Now you -have to set the wanted transport per-loadVideo calls via its -defaultAudioTrack option.

-

Examples

-

Without audio description:

-
// In the previous version
-player = new RxPlayer({
-  defaultLanguage: "en"
-});
-
-// becomes
-player = new RxPlayer();
-player.loadVideo({
-  defaultAudioTrack: {
-    language: "en"
-  },
-  // ...
-});
-
-

With audio description:

-
player = new RxPlayer();
-player.loadVideo({
-  defaultAudioTrack: {
-    language: "en",
-    audioDescription: true
-  },
-  // ...
-});
-
-

-

-

defaultSubtitle

-

What changed

-

This option has been removed from the constructor to simplify the API. Now you -have to set the wanted transport per-loadVideo calls via its -defaultTextTrack option.

-

Examples

-

Without closed caption:

-
// In the previous version
-player = new RxPlayer({
-  defaultSubtitle: "en"
-});
-
-// becomes
-player = new RxPlayer();
-player.loadVideo({
-  defaultTextTrack: {
-    language: "en"
-  },
-  // ...
-});
-
-

With closed caption:

-
player = new RxPlayer();
-player.loadVideo({
-  defaultTextTrack: {
-    language: "en",
-    closedCaption: true
-  },
-  // ...
-});
-
-

-

-

initVideoBitrate / initAudioBitrate

-

What changed

-

Those options just changed their name:

-
    -
  • initVideoBitrate becomes initialVideoBitrate
    • -
  • initAudioBitrate becomes initialAudioBitrate
    • -
-

This is to mainly to add clarity to the API.

-

Examples

-
// In the previous version
-player = new RxPlayer({
-  initVideoBitrate: 1e6,
-  initAudioBitrateBitrate: 2e4
-});
-
-// becomes
-player = new RxPlayer({
-  initialVideoBitrate: 1e6,
-  initialAudioBitrateBitrate: 2e4
-});
-
-

-

-

defaultAudioTrack

-

What changed

-

This option has been removed from the constructor to simplify the API. Now you -have to set the wanted transport per-loadVideo calls via its -defaultAudioTrack option, which has the exact same format.

-

-

-

defaultTextTrack

-

What changed

-

This option has been removed from the constructor to simplify the API. Now you -have to set the wanted transport per-loadVideo calls via its -defaultTextTrack option, which has the exact same format.

-

-

-

transport

-

What changed

-

This option has been removed from the constructor to simplify the API. Now you -have to set the wanted transport per-loadVideo calls via its transport -option, which has the exact same format.

-

-

-

transportOptions

-

What changed

-

This option has been removed from the constructor to simplify the API. Now you -have to set the wanted transport options per-loadVideo calls via its -transportOptions option, which has the exact same format.

-

-

-

loadVideo

-

loadVideo is the central method of the RxPlayer and changed enough to earn -its own chapter.

-

Both parameters and the return value changed.

-

-

-

Return value

-

What changed

-

loadVideo does not return anything anymore.

-

Replacement examples

-

If you want to know when the player is on error, you will have to listen to the -error events:

-
player.addEventListener("error", (error) => {
-  console.log("content on error");
-});
-
-

If you want to know when the content is loaded, you will have to listen to when -the playerStateChange events:

-
player.addEventListener("playerStateChange", (state) => {
-  switch (state) {
-    case "LOADING":
-      console.log("the content is loading");
-      break;
-    case "LOADED":
-      console.log("the content has loaded");
-      break;
-    case "PLAYING":
-      console.log("the content is now playing");
-      break;
-  }
-});
-
-

Bear in mind however that both are triggered when ANY content you choosed to -play are loaded/on error, not just the last one.

-

-

-

defaultLanguage parameter

-

What changed

-

defaultLanguage is replaced by the defaultAudioTrack option, which -supports audio description.

-

Replacement example

-

Without audio description:

-
// In the previous version
-player.loadVideo({
-  url: someURL,
-  defaultLanguage: "en"
-});
-
-// becomes
-player.loadVideo({
-  url: someURL,
-  defaultAudioTrack: {
-    language: "en"
-  }
-});
-
-

With audio description:

-
player.loadVideo({
-  url: someURL,
-  defaultAudioTrack: {
-    language: "en",
-    audioDescription: true
-  }
-});
-
-

-

-

defaultSubtitle parameter

-

What changed

-

defaultSubtitle is replaced by the defaultTextTrack option, which -supports closed caption.

-

Replacement example

-

Without closed caption:

-
// In the previous version
-player.loadVideo({
-  url: someURL,
-  defaultSubtitle: "en"
-});
-
-// becomes
-player.loadVideo({
-  url: someURL,
-  defaultTextTrack: {
-    language: "en"
-  }
-});
-
-

With closed caption:

-
player.loadVideo({
-  url: someURL,
-  defaultTextTrack: {
-    language: "en",
-    closedCaption: true
-  }
-});
-
-

-

-

images parameter

-

What changed

-

images is renamed as supplementaryImageTracks for clarity.

-

Replacement example

-
// In the previous version
-player.loadVideo({
-  url: someURL,
-  images: {
-    mimeType: "application/bif",
-    url: "",
-  },
-});
-
-// becomes
-player.loadVideo({
-  url: someURL,
-  supplementaryImageTracks: {
-    mimeType: "application/bif",
-    url: "",
-  },
-});
-
-

-

-

subtitles parameter

-

What changed

-

You have two possibilities. Either:

-
    -
  1. Use the exernal TextTrackRenderer tool, documented -here. This is the preferred way.
    2. -
  2. Replace subtitles by supplementaryTextTracks. Please note -however that supplementaryTextTracks is a deprecated feature.
    3. -
-

Replacement example

-

If you go under the supplementaryTextTracks route:

-
// In the previous version
-player.loadVideo({
-  url: someURL,
-  subtitles: {
-    mimeType: "application/x-sami",
-    url: "",
-  },
-});
-
-// becomes
-player.loadVideo({
-  url: someURL,
-  supplementaryTextTracks: {
-    mimeType: "application/x-sami",
-    url: "",
-  },
-});
-
-

If you prefer to use the TextTrackRenderer instead, I invite you to directly -read, its documentation, as the API is completely -different there.

-

-

-

timeFragment parameter

-

What changed

-

The timeFragment parameter has been completely removed.

-

If you want to start at a precize point in the content, you can use the -startAt parameter instead, documented -here.

-

If you want to end at a precize point in the content, this has not been -re-implemented as I do not know for now any usecase for that. Please open an -issue if you need that feature.

- - -### manifests parameter ######################################################## -

What changed

-

The manifests parameter has been completely removed. Its behavior can easily -be replaced by two existing options: url and keySystems:

-
    -
  • -

    The url of the first object in the manifests array should be put in the -url parameter

    -
    • -
  • -

    Each keySystem property defined in the manifests array should be put -in the keySystems array, in the same order

    -
    • -
-

Doing this should lead to the exact same behavior.

-

Replacement example

-
// In the previous version
-player.loadVideo({
-  manifests: [

-      url: someURL1
-      keySystem: keySystem1
-    },
-    {
-      url: someURL2
-    },
-    {
-      url: someURL3
-      keySystem: keySystem3
-    },
-    {
-      url: someURL4
-      keySystem: keySystem4

-});
-
-// becomes
-player.loadVideo({

-  keySystems: [
-    keySystem1,
-    keySystem3,

-  ],
-});
-
-

-

Removed methods

-

-

-

getVideoMaxBitrate / getAudioMaxBitrate / setVideoMaxBitrate / setAudioMaxBitrate

-

What changed

-

Those methods just changed their name to have a more coherent API:

-
    -
  • setVideoMaxBitrate becomes setMaxVideoBitrate
    • -
  • setAudioMaxBitrate becomes setMaxAudioBitrate
    • -
  • getVideoMaxBitrate becomes getMaxVideoBitrate
    • -
  • getAudioMaxBitrate becomes getMaxAudioBitrate
    • -
-

This is mostly done to be aligned with the maxVideoBitrate and -maxAudioBitrate constructor options.

-

Replacement examples

-
setVideoMaxBitrate
-
// In the previous version
-player.setVideoMaxBitrate(1500);
-
-// becomes
-player.setMaxVideoBitrate(1500);
-
-
setAudioMaxBitrate
-
// In the previous version
-player.setAudioMaxBitrate(999);
-
-// becomes
-player.setMaxAudioBitrate(999);
-
-
getVideoMaxBitrate
-
// In the previous version
-maxBitrate = player.getVideoMaxBitrate();
-
-// becomes
-maxBitrate = player.getMaxVideoBitrate();
-
-
getAudioMaxBitrate
-
// In the previous version
-maxBitrate = player.getAudioMaxBitrate();
-
-// becomes
-maxBitrate = player.getMaxAudioBitrate();
-
-

-

-

setVideoBufferSize / setAudioBufferSize / getVideoBufferSize / getAudioBufferSize

-

What changed

-

Those four methods were removed to be replaced with simpler generic -getWantedBufferAhead/setWantedBufferAhead methods. They also take -seconds in argument.

-

The only difference is that you cannot discriminate by type of buffer -(audio/video) anymore. This is for done for multiple reasons:

-
    -
  • -

    There are more than two types of buffers (for now there are four: audio, -video, text and image). Adding one methods per type could be cumbersome for -the user (for example, when wanting to set the limit for three or four of -them)

    -
    • -
  • -

    More buffer-related APIs were added which are type-agnostic. Adding one -A per-type would be heavy both for the rx-player and for the application -using it

    -
    • -
  • -

    It’s easier to explain through the documentation, for people that do not -want to understand the nitty-gritty of a player

    -
    • -
  • -

    We did not encounter any usecase for separate methods yet

    -
    • -
-

Replacement examples

-
setVideoBufferSize
-
// In the previous version
-player.setVideoBufferSize(15);
-
-// becomes (also affect audio, text and image buffer)
-player.setWantedBufferAhead(15);
-
-
setAudioBufferSize
-
// In the previous version
-player.setAudioBufferSize(10);
-
-// becomes (also affect video, text and image buffer)
-player.setWantedBufferAhead(10);
-
-
getVideoBufferSize
-
// In the previous version
-bufferSize = player.getVideoBufferSize();
-
-// becomes
-bufferSize = player.getWantedBufferAhead();
-
-
getAudioBufferSize
-
// In the previous version
-bufferSize = player.getAudioBufferSize();
-
-// becomes
-bufferSize = player.setWantedBufferAhead();
-
-

-

-

asObservable

-

What Changed

-

asObservable has been completely removed for the following reasons:

-
    -
  • -

    it exposed too much of the player. Guaranteeing compatibility between -versions was too hard.

    -
    • -
  • -

    it exposed the internal RxJS library, which we now stop to do for various -reasons.

    -
    • -
-

-

-

getAvailableLanguages

-

What Changed

-

This method now has been completely replaced by getAvailableAudioTracks -which adds audio description support. See the API -documentation for more infos.

-

Replacement example

-
// In the previous version
-audioTracks = player.getAvailableLanguages();
-
-if (audioTracks && audioTracks.length) {
-  console.log("audio languages:", ...audioTracks);
-} else {
-  console.log("no audio language");
-}
-
-// -------------------------------
-
-// becomes
-audioTracks = player.getAvailableAudioTracks();
-
-if (audioTracks && audioTracks.length) {
-  console.log("audio languages:", ...audioTracks.map(track => track.language));
-} else {
-  console.log("no audio language");
-}
-
-

-

-

getAvailableSubtitles

-

What Changed

-

This method now has been completely replaced by getAvailableTextTracks which -adds closed caption support. See the API documentation for -more infos.

-

Replacement example

-
// In the previous version
-subtitleTracks = player.getAvailableSubtitles();
-
-if (subtitleTracks && subtitleTracks.length) {
-  console.log("subtitle languages:", ...subtitleTracks);
-} else {
-  console.log("no subtitle language");
-}
-
-// -------------------------------
-
-// becomes
-subtitleTracks = player.getAvailableTextTracks();
-
-if (subtitleTracks && subtitleTracks.length) {
-  console.log("subtitle languages:",
-    ...subtitleTracks.map(track => track.language));
-} else {
-  console.log("no subtitle language");
-}
-
-

-

-

getAverageBitrates

-

What Changed

-

getAverageBitrates is deleted. It can normally be completely replaced by the -bitrateEstimationChange -event which can be -listened thanks to the addEventListener -method.

-

-

-

getCurrentTime

-

What Changed

-

getCurrentTime was separated in two methods:

-
    -
  • -

    getWallClockTime: returns the wall-clock-time of the current position in -seconds. -That is:

    -
      -
    • for live content, get a timestamp in seconds of the current position.
      • -
    • for static content, returns the position from beginning, also in -seconds.
      • -
    -

    This is the closest implementation of getCurrentTime. The only difference -being that for live contents, a timestamp will be returned (in seconds), not -a Date object

    -
    • -
  • -

    getPosition: returns the video element’s current position, in seconds. The -difference with getWallClockTime is that for live contents the position is -not re-calculated to match a live timestamp.

    -
    • -
-

If you do not know if you want to use getWallClockTime or getPosition:

-
    -
  • If what you want is to display the current time to the user, you will most -probably want to use getWallClockTime.
    • -
  • If what you want is to interact with the player’s API or perform other -actions with the real player data, use getPosition.
    • -
-

Replacement example

-
// In the previous version
-currentTime = player.getCurrentTime();
-
-if (currentTime instanceof Date) {
-  currentTime = currentTime.getTime() / 1000;
-}
-
-// -------------------------------
-
-// becomes
-currentTime = player.getWallClockTime();
-
-

-

-

getDebug / showDebug / hideDebug / toggleDebug

-

What Changed

-

Those will be removed from the API and won’t be replaced.

-

Those methods were used internally, but were exposed like regular APIs. -They have not much usage either as other APIs should be sufficient.

-

-

-

getEndTime

-

What Changed

-

getEndTime was removed from the API. Its role can be replaced by the new -getMaximumPosition API which will return the maximum position the user can -seek to.

-

Replacement example

-
// In the previous version
-endTime = player.getEndTime();
-
-// becomes
-endTime = player.getMaximumPosition();
-
-

-

-

static getErrorCodes

-

What Changed

-

This static method was updated to a static property ErrorCodes.

-

Replacement example

-
// In the previous version
-errorCodes = player.getErrorCodes();
-
-// becomes
-errorCodes = player.ErrorCodes;
-
-

-

-

static getErrorTypes

-

What Changed

-

This static method was updated to a static property ErrorTypes.

-

Replacement example

-
// In the previous version
-errorTypes = player.getErrorTypes();
-
-// becomes
-errorTypes = player.ErrorTypes;
-
-

-

-

getImageTrack

-

What Changed

-

getImageTrack is now replaced by both:

-
    -
  • -

    the imageTrackUpdate event (the closest to getImageTrack previous -behavior) triggered each time new image data is received with the complete -image data as a payload (all the image data from the current image -adaptation) in a data property.

    -
    • -
  • -

    the getImageTrackData method, which returns an array for all the -currently referenced image data for the seekable content.

    -
    • -
-

Replacement example

-
// In the previous version
-player.getImageTrack().subscribe(images => {
-  displaySomeImages(images);
-});
-
-// becomes
-player.addEventListener("imageTrackUpdate", ({ data }) => {
-  displaySomeImages(data);
-});
-
-

-

-

getLanguage

-

What Changed

-

getLanguage has been replaced by getAudioTrack which adds audio -description support.

-

Replacement example

-
// In the previous version
-track = player.getLanguage();
-
-if (track) {
-  console.log("audio language:", track);
-} else {
-  console.log("no audio language");
-}
-
-// ------------------------
-
-// becomes
-track = player.getAudioTrack();
-
-if (track) {
-  console.log("audio language:", track.language);
-} else {
-  console.log("no audio language");
-}
-
-

-

-

getMetrics

-

What Changed

-

getMetrics is removed from the API and is not replaced. This is due to the fact -that the ABR (adaptive bitrate) strategy completely changed, and re-implementing -this method is not straightforward.

-

-

-

getStartTime

-

What Changed

-

getStartTime was removed from the API. Its role can be replaced by the new -getMinimumPosition API which will return the minimum position the user can -seek to.

-

Replacement example

-
// In the previous version
-startTime = player.getStartTime();
-
-// becomes
-startTime = player.getMinimumPosition();
-
-

-

-

getSubtitle

-

What Changed

-

getSubtitle has been replaced by getTextTrack which adds closed caption -support.

-

Replacement example

-
// In the previous version
-track = player.getSubtitle();
-
-if (track) {
-  console.log("text language:", track);
-} else {
-  console.log("no text language");
-}
-
-// ------------------------
-
-// becomes
-track = player.getTextTrack();
-
-if (track) {
-  console.log("text language:", track.language);
-} else {
-  console.log("no text language");
-}
-
-

-

-

goToStart

-

What Changed

-

goToStart is removed from the API and not replaced. You might want to use -both getMinimumPosition and seekTo to seek to the earliest part of the -content.

-

Replacement example

-
// In the previous version
-player.goToStart();
-
-// becomes
-player.seekTo(player.getMinimumPosition());
-
-

-

-

isLanguageAvailable / isSubtitleAvailable

-

What Changed

-

Those methods are removed and not replaced. Use getAvailableAudioTracks / -getAvailableTextTracks instead.

-

Replacement examples

-
isLanguageAvailable
-
// In the previous version
-console.log(player.isLanguageAvailable("fr"));
-
-// becomes
-const tracks = player.getAvailableAudioTracks();
-console.log(!!tracks && tracks.some(({ language }) => language === "fr"));
-
-
isSubtitleAvailable
-
// In the previous version
-console.log(player.isSubtitleAvailable("fr"));
-
-// becomes
-const tracks = player.getAvailableTextTracks();
-console.log(!!tracks && tracks.some(({ language }) => language === "fr"));
-
-

-

-

normalizeLanguageCode

-

What Changed

-

normalizeLanguageCode is removed and not replaced. Switching audio and text -tracks is now id-based, so the language code has much less use than before.

-

-

-

setLanguage

-

What Changed

-

setLanguage has been replaced by setAudioTrack which adds audio -description support.

-

Replacement example

-
// In the previous version
-try {
-  player.setLanguage("fr");
-} catch(e) {
-  console.warn("no track found with this language");
-}
-
-// -------------------------
-
-// becomes
-track = player.getAvailableAudioTracks();
-const indexOf = tracks && tracks.indexOf(({ language }) => language === "fr");
-
-if (tracks && indexOf !== -1) {
-  player.setAudioTrack(tracks[indexOf].id);
-} else {
-  console.warn("no track found with this language");
-}
-
-

-

-

setSubtitle

-

What Changed

-

setSubtitle has been replaced by setTextTrack which adds closed caption -support.

-

Replacement example

-
// In the previous version
-try {
-  player.setSubtitle("fr");
-} catch(e) {
-  console.warn("no track found with this language");
-}
-
-// -------------------------
-
-// becomes
-track = player.getAvailableTextTracks();
-const indexOf = tracks && tracks.indexOf(({ language }) => language === "fr");
-
-if (tracks && indexOf !== -1) {
-  player.setTextTrack(tracks[indexOf].id);
-} else {
-  console.warn("no track found with this language");
-}
-
-

-

-

Changed methods

-

-

-

seekTo

-

What Changed

-

In the previous version, you could give directly a Number or Date object to -seekTo. What it would do with that depended on if the content was a live -content or not:

-
    -
  • -

    for live content, a time in milliseconds or a Date object was expected -corresponding to the WallClock time (timestamp of the live content)

    -
    • -
  • -

    for non-live content, the time in seconds was expected, which was the time -the video tag seek to.

    -
    • -
-

Now, you can only give a number or an Object to this function. If you give a -number, it will allways be the new time in seconds the video tag will seek to. -This call is documented here.

-

Replacement example

-

To copy the old behavior for live contents, you can set the wallClockTime -property:

-
// seeking at 30 minute before now on what is broadcasted live
-
-// In the previous version:
-player.seekTo(Date.now() - 30*60 * 1000);
-
-// becomes
-player.seekTo({ wallClockTime: Date.now() / 1000 - 30*60});
-
-

To copy the old behavior for non-live contents, nothing has changed:

-
// seek to the tenth second for a non live content
-
-// In the previous version:
-player.seekTo(10);
-
-// becomes
-player.seekTo(10);
-
-

-

-

setVideoBitrate / setAudioBitrate

-

What Changed

-

Previously, calling this method in the following situation threw an error:

-
    -
  • no content is playing
    • -
  • the set bitrate does not exist
    • -
-

Now, this call never throws:

-
    -
  • -

    if you call it while no content is playing, the limit is still set for the -next content played.

    -
    • -
  • -

    if the set bitrate does not exist on the current content, the value will -just act as a ceil (the chosen bitrate will be the one immediately -inferior). If still no bitrate is inferior to it, the lowest bitrate will be -chosen instead.

    -
    • -
-

-

-

getUrl

-

What Changed

-

Previously, calling this method when no content is playing threw an error.

-

Now, doing so will just return undefined.

-

-

-

isLive

-

What Changed

-

Previously, calling this method when no content is playing threw an error.

-

Now, doing so will just return false.

-

-

-

Removed events

-

-

-

currentTimeChange

-

What Changed

-

The currentTimeChange is replaced by the positionUpdate event.

-

It is similar to currentTimeChange but with the following properties -removed:

-
    -
  • buffered
    • -
  • paused
    • -
  • range
    • -
  • readyState
    • -
  • stalled
    • -
  • ts (replaced by position)
    • -
  • playback (replaced by playbackRate)
    • -
  • gap (replaced by bufferGap)
    • -
-

And with the following property updated:

-
    -
  • wallClockTime: will go from a Date object to the same indication in -seconds.
    • -
-

-

-

progress

-

What Changed

-

progress events are removed and not replaced. This is because it exposed to -much of our internal logic.

-

-

-

languageChange

-

What Changed

-

languageChange is replaced by the audioTrackChange event, which supports -audio description.

-

Replacement example

-
// In the previous version
-player.addEventListener("languageChange", (lang) => {
-  console.log("language changed to", lang);
-});
-
-// becomes
-player.addEventListener("audioTrackChange", (track) => {
-  const { language, id, audioDescription } = track;
-  console.log("language changed to", language);
-});
-
-

-

-

subtitleChange

-

What Changed

-

subtitleChange is replaced by the textTrackChange event, which supports -closed caption.

-

Replacement example

-
// In the previous version
-player.addEventListener("subtitleChange", (lang) => {
-  console.log("subtitle changed to", lang);
-});
-
-// becomes
-player.addEventListener("textTrackChange", (track) => {
-  const { language, id, closedCaption } = track;
-  console.log("language changed to", language);
-});
-
-

-

-

nativeTextTrackChange

-

What Changed

-

nativeTextTrackChange is replace by the nativeTextTracksChange (notice -the supplementary “s”) event.

-

Three things have changed comparatively:

-
    -
  • -

    The payload of this event now is an array of TextTrack element. -Previously, it was a single TextTrackElement (which correspond to the -first in the array).

    -
    • -
  • -

    The event is also triggered when a TextTrackElement is removed from the -<video> tag. Previously, it was only when added.

    -
    • -
  • -

    The event is fired even if no content is playing

    -
    • -
-

This is to support edge cases where the <track> element could be modified by -the user of our library, in which case the RxPlayer could give false -information. Also, this allows to signal when a TextTrack has been removed -from the DOM to help you free up ressources on your side.

-

Replacement example

-
// In the previous version
-player.addEventListener("nativeTextTrackChange", (track) => {
-  console.log("the track changed:", track);
-});
-
-// becomes
-player.addEventListener("nativeTextTracksChange", (tracks) => {
-  if (tracks.length === 0) {
-    console.log("no active track!");
-  } else {
-    // in most usecases you can just check the first element.
-    // (this will have the exact same effect than the previous event)
-    console.log("the track changed:", tracks[0]);
-  }
-});
-
-

-

-

Changed events

-

-

-

positionUpdate

-

What Changed

-

The maximumBufferTime property has now been removed from positionUpdate -events. This is because this is now the exact same thing than:

-
    -
  • liveGap + position (from the same event) for live contents
    • -
  • duration (from the same event) for non-live contents
    • -

On using TypeScript

-

We recently (as from v3.0.1) have chosen to switch the rx-player codebase -from plain JavaScript to TypeScript.

-

This was in fact going for more than a month before the official v3.0.1 -release, a time during which we maintained both JavaScript and TypeScript -versions of the player:

-
    -
  • We ported fixes we found with our typescript branch on the regular releases
    • -
  • We ported improvements we were doing on regular releases to our typescript -branch.
    • -
-

This is one of the reasons why you saw a LOT of release candidates for the -v3.0.0, as we were seeing more typos and other minor errors in master we had -to fix.

-

-

Why refactoring?

-

It may appear shocking to most developpers, but we do not dislike JavaScript. -The language has its quirks (that we, as JS developers, learned to avoid the -hard way) but it has a flexibility that few other languages can compete with.

-

For example, our codebase adopts concepts of both Functional Programming and -Object Oriented Programming and it still looks idiomatic to the JS language -(even more since we’re using ES6+ and RxJS).

-

In recent years, we were spectators of a huge trend to write desktop -applications (thanks to Electron), mobile applications (e.g. with react-native) -and servers (thanks to Node.js) in what is basically JavaScript. Because it is -becoming a kind of developper -lingua-franca, the pool of -possible contributors is amazing. Moreover, as many developpers can read and -judge the quality of JavaScript codebases, open-sourcing becomes only more -exciting with a JavaScript project.

-

Despite this, we had issues with where our codebase was evolving toward:

-
    -
  • -

    it was becoming fairly large, and the old team in charge of the project -left. We lost a lot of the code’s knowledge in that process.

    -
    • -
  • -

    to renew the codebase and bring new features, some refactoring were -needed. But we did not have enough confidence on our code to do them.

    -
    • -
  • -

    As new features were added, bugs were also added. -A majority of these issues were either based on typos, or on a wrong -representation of the data structure we had at a certain point in the code.

    -
    • -
  • -

    There also were multiple coding styles in different parts of the player, -depending on the “era” in which the file was written in. -This harms the “welcomeness” of the codebase, which, as an open-source -library, is an important factor.

    -
    • -
-

We liked to present the rx-player as a really maintanable project, but by -keeping things like they were, we had a substantial risk of going toward the -exact opposite.

-

With that in mind, we observed that none of us were developping in “browser’s -JavaScript” anymore, as most projects we worked on made usage of Babel for -years now. -The code we write in looks very different than what is transpiled to run on -browsers (we’re treating the “real” JavaScript today as a - easily -readable - bytecode).

-

As such, we knew we needed to do something about the code, and we were not -hesitant to do substantial changes, while not wanting to depart too much from -JavaScript.

-

-

Why TypeScript?

-

When we were brainstorming on what we could do to improve our codebase, we edged -a lot around a better type system. As functional-programming fans, we were -seeing some wonderful type systems in other programming languages (Haskell, -Scala, Rust) that we thought could partially answer to a lot of our problems. -One of us worked with Scala in its previous professional experience, this also -amplified the need to “improve” our JavaScript.

-

In the browser’s world, there were two possibilities:

-
    -
  • using another language transpiled to JavaScript (elm, PureScript, Scala.js)
    • -
  • using a “superset” of JavaScript, which gives us typings without changing -the base language
    • -
-

The first solution was not wanted, as we would lost a lot of possible -contributors (both in-house or external), but also because it would need a lot -more work we could not afford.

-

The second solution was the only one we actually seriously thought about. -As such, a little more than a month ago, We began porting the rx-player in both -flow and TypeScript, to see which type system we could profit the more from.

-

We found both to be really similar for what we wanted to achieve. TypeScript -was finally chosen because:

-
    -
  1. -

    It has a lot more traction than flow today, with a lot more tools and a lot -more codebases written in/for TypeScript. This gives us more guarantees -about the language’s future.

    -
    2. -
  2. -

    RxJS, VisualStudioCode, BabylonJS and AngularJS are all well-regarded -codebases, all written in TypeScript. We consider this as a proof that the -language can helps us toward our goals, and that the language is mature -enough today.

    -
    3. -
  3. -

    The future of flow seemed too uncertain. This is even more the case now -that Facebook is working on the Reason -language.

    -
    4. -
-

-

What we have done

-

When we began to really consider switching the source to TypeScript, we set one -goal before the release: The whole RxPlayer should work under TypeScript’s -“strict” mode, and the code should look enough like idiomatic TypeScript to be -presented as a TypeScript project (and not as a ported JavaScript one).

-

As such, we worked on every files in the src directory, even doing important -refactorings, to ensure our code was elegant enough to be maintenable and -presentable. -Today, we have the confidence that the base we have can be approached naturally -in a TypeScript way.

-

We “switched” every rx-player source and unit tests files.

-

-

What we still need to do

-

Some parts of the code still need work to look like perfect idiomatic -TypeScript.

-

For example, the part gluing our networking logic to the streaming logic (what -we call the “pipeline”) relies too much on any types and casting. -This is the main part that needs work today. Specifically, the -manifest-refreshing logic shares too much logic with the segment-downloading -one, leading to types impossible to set.
