An HTML5 Flash Video (FLV) Player written in pure JavaScript without Flash. LONG LIVE FLV!
This project relies on Media Source Extensions to work.
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.
flv.js is written in ECMAScript 6, transpiled into ECMAScript 5 by Babel Compiler, and bundled with Browserify.
Demo

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
<script src="flv.min.js"></script>
<video id="videoElement"></video>
<script>
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();
}
</script>
