flv.js

An HTML5 Flash Video (FLV) Player written in pure JavaScript without Flash. LONG LIVE FLV!

This project relies on Media Source Extensions to work.

For FLV live stream playback, please consider mpegts.js which is under active development.

This project will become rarely maintained.

Overview

flv.js works by transmuxing FLV file stream into ISO BMFF (Fragmented MP4) segments, followed by feeding mp4 segments into an HTML5 element through Media Source Extensions API.

Demo

http://bilibili.github.io/flv.js/demo/

Features 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! Installation npm install --save flv.js Build npm ci # install dependencies / dev-dependences npm run build:debug # debug version flv.js will be emitted to /dist npm run build # minimized release version flv.min.js will be emitted to /dist

cnpm mirror is recommended if you are in Mainland China.

CORS

If you use standalone video server for FLV stream, Access-Control-Allow-Origin header must be configured correctly on video server for cross-origin resource fetching.

See cors.md for more details.

Getting Started if (flvjs.isSupported()) { var videoElement = document.getElementById('videoElement'); var flvPlayer = flvjs.createPlayer({ type: 'flv', url: 'http://example.com/flv/video.flv' }); flvPlayer.attachMediaElement(videoElement); flvPlayer.load(); flvPlayer.play(); } 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 Multipart playback
