kaltura-application-framework-guide

An integration guide for developers implementing the Kaltura Applications Framework in their own applications.

To run the sample code you'll need:

• A Kaltura Instance URL, which you'll receive with your KAF account. Send us an email at [email protected] to sign up for an account.
• Your Kaltura Partner ID and Admin Secret, which can be found under Integration Settings in the Kaltura Management Console.
• The Kaltura PHP 5 Library which can be found here

These should all be set in the config, in addition to:

• The UI Conf ID (or player ID) that will be used for embedding the video player in the webpage. The ID for each player can be found under Studio in the KMC.
• The Domain where the sample code is being hosted - change this accordingly.
• The Kaltura Service URL - which should stay as is unless you've been informed otherwise.

You'll also find the generateSession function which creates a Kaltura Session using the Kaltura PHP Client Library. This KS will be included in calls made to the KAF endpoint, in order to authenticate and determine privileges.

Templates

Basic functionalities of KAF that every video application would contain: a media gallery and a way to see a smaller collection of content

My Media

This is like a personalized media locker for end users where they can upload assets and manage videos and other media files. A Kaltura Session with the userId of the user is created in order to display the relevant entries. You can change the userId variable in mymedia_template.php to see how this affects the content.

Collection

A collection is a category of content that contains entries from the application owner's account. The Collection Name is passed into the privileges string, and KAF maps it to the relevant category. The collection name can be modified via the url, along with the user ID and roles. This makes it easy to see what will be displayed in the case of varying users with varying content and permissions. The userRole is set to viewer but should be set to privateOnlyRole in order to allow publishing. A contextualRole determines what a user can do in the context of a collection, and we've set ours to 4 which is none, meaning the user can only access public collections. Other options are:

• 0: MANAGER, manages all aspects of collection
• 1: MODERATOR, notified on new pending items, can access moderation queue for approval/rejection
• 2: CONTRIBUTOR, can add items to collection
• 3: MEMBER, can access collection (relevant if collection is restricted/private)
• 4: NONE, can access public collections Read more about roles and permissions here.

Media Pickers

The Browse, Search and Embed iFrame (BSE), a key component of KAF, is used for the sole purpose of selecting content from the user's own "my media" library or shared repository that is enabled in the KAF instance that the user is given access to. You'll find similar workflows in each of the four use cases: The Video Landing Page allows users to choose a video for the placeholder in a landing page template. We've added a landing page and a file DB that will hold onto the entry after it was selected. Thumbnail Selection for Emails provides a tool for picking a frame (image) from a video that will be used as a thumbnail in an email.

Grabbable Embed is a more customizable approach to the above scenarios. It allows users to generate embed codes for specific media assets in order to embed in their own pages

Product Image Selection is like the grabbabale embed, but for a product image tag.

You'll find some similarities in the code for each of the pickers

BSE_RETURN_URL: BSE stands for Browse Search and Embed. KAF will call this url once an asset is selected. It must reside on the same domain as the page hosting the BSE iFrame and the URL must be in safe-encoding.

userId: This is dynamic. A user ID can be any string but will generally be the email address of the user accessing the application.

privileges: The privileges string to be used when creating the Kaltura Session, in order to determine user's access to the content. The actionslimit prevents the generated token from being used for any other API calls. The privateOnlyRole is the minimum role allowed for access to My Media. Read more about roles and permissions here

bseURL: The URL to KAF which contains the Kaltura Session which was generated using the userId and privileges

Handlers: Each of the media pickers has its own handler, a script which collects the post data, and sends it back as an object to the handleSelected function in each of the pickers.
