mpegts.js 

日本語 中文说明

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.

Overview

mpegts.js works by transmuxing MPEG2-TS stream into ISO BMFF (Fragmented MP4) segments, followed by feeding mp4 segments into an HTML5 element through [Media Source Extensions][] API.

[Media Source Extensions]: https://w3c.github.io/media-source/

News

- v1.8.0

Support working on iOS Safari with iOS 17.1+ through Apple's ManagedMediaSource API

Great performance improvements by supporting MSE in Workers on Chrome, Safari 18 (includes iOS)

Introduced support for AV1 over MPEG-TS

Introduced support for AV1 over HTTP-FLV defined in Enhanced RTMP

Support chasing live latency more smoothly by changing playback rate

Introduced ATSC EAC-3 audio codec in MPEG-TS

Support Opus and FLAC audio codec over HTTP-FLV (Enhanced RTMP)

- v1.7.3

Introduced [Enhanced RTMP] with HEVC support for FLV.

Introduced Opus and ATSC AC-3 audio codec support for MPEG-TS.

Introduced LOAS AAC support for MPEG-TS.

demo with aribb24.js

Features

- Playback for MPEG2-TS stream with H.264/H.265 + AAC codec transported in http(s) or WebSocket
- Playback for FLV stream with H.264/H.265 + AAC codec transported in http(s) or WebSocket
- Extremely low latency of less than 1 second in the best case
- Playback for .m2ts file 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)

CORS

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.

Installation

``bash
npm install --save mpegts.js
`

Build

`bash
npm install # install dev-dependencies
npm install -g webpack-cli # install build tool
npm run build # packaged & minimized js will be emitted in dist folder
`

cnpm mirror is recommended if you are in Mainland China.

Getting Started

`html



`

mpegts.js could be tested with Simple Realtime Server.

TODO

- MPEG2-TS static file playback (seeking is not supported now)

Limitations

- mpeg2video is not supported
- HTTP MPEG2-TS live stream could not work on old browsers like IE11
- mpegts.js is not usable on iOS version 17.0 or older caused by the banning of [Media Source Extensions][] (available on iPadOS), iOS 17.1 works through Managed Media Source API

Features inherited from flv.js

- 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!

FLV playback limitations

- MP3 audio codec is currently not working on IE11 / Edge
- HTTP FLV live stream is not currently working on all browsers, see livestream.md

FLV Multipart playback

You only have to provide a playlist for MediaDataSource. See multipart.md

Livestream playback

See livestream.md

API and Configuration

See api.md

Debug

`bash
npm install # install dev-dependencies
npm install -g webpack-cli # install build tool
npm run build:debug # packaged & minimized js will be emitted in dist folder
`
