HTML5 MPEG2-TS stream player written in TypeScript & JavaScript.
mpegts.js is optimized for low-latency live stream playback, such as DVB/ISDB television or surveillance cameras.
This project is based on flv.js.
mpegts.js works by transmuxing MPEG2-TS stream into ISO BMFF (Fragmented MP4) segments, followed by feeding mp4 segments into an HTML5 <video> element through Media Source Extensions API.
http://xqq.github.io/mpegts.js/demo/
- Playback for MPEG2-TS stream with H.264 + AAC codec transported in http(s) or WebSocket
- Extremely low latency of less than 1 second in the best case
- Playback for
.m2tsfile like BDAV/BDMV with 192 bytes TS packet, or 204 bytes TS packet - Support handling dynamic codec parameters change (e.g. video resolution change)
- Support Chrome, FireFox, Safari, Edge (Old or Chromium) or any Chromium-based browsers
- Support chasing latency automatically for internal buffer of HTMLMediaElement
- Low CPU overhead and low memory usage (JS heap takes about 10MiB for each instance)
- Support extracting PES private data (stream_type=0x06) like ARIB B24 subtitles (with aribb24.js)
- Support Timed ID3 Metadata (stream_type=0x15) callback (TIMED_ID3_METADATA_ARRIVED)
If you use standalone video server for MPEG2-TS stream, Access-Control-Allow-Origin header must be configured correctly on video server for cross-origin resource fetching.
See cors.md for more details.
npm install --save mpegts.jsnpm install # install dev-dependences
npm install -g webpack-cli # install build tool
npm run build # packaged & minimized js will be emitted in dist foldercnpm mirror is recommended if you are in Mainland China.
<script src="mpegts.js"></script>
<video id="videoElement"></video>
<script>
if (mpegts.getFeatureList().mseLivePlayback) {
var videoElement = document.getElementById('videoElement');
var player = mpegts.createPlayer({
type: 'mse', // could also be mpegts, m2ts, flv
isLive: true,
url: 'http://example.com/live/livestream.ts'
});
player.attachMediaElement(videoElement);
player.load();
player.play();
}
</script>mpegts.js could be tested with Simple Realtime Server.
- MPEG2-TS static file playback (seeking is not supported now)
- H.265/HEVC video codec support (only Safari support HEVC for now)
- MP3/AC3 audio codec support
- AV1/OPUS codec over MPEG2-TS stream support (?)
- mpeg2video is not supported
- HTTP MPEG2-TS live stream could not work on old browsers like IE11
- mpegts.js is not usable on iOS caused by the banning of Media Source Extensions (available on iPadOS)
- FLV container with H.264 + AAC / MP3 codec playback
- Multipart segmented video playback
- HTTP FLV low latency live stream playback
- FLV over WebSocket live stream playback
- Compatible with Chrome, FireFox, Safari 10, IE11 and Edge
- Extremely low overhead, and hardware accelerated by your browser!
- MP3 audio codec is currently not working on IE11 / Edge
- HTTP FLV live stream is not currently working on all browsers, see livestream.md
You only have to provide a playlist for MediaDataSource. See multipart.md
See livestream.md
See api.md
