Package Exports

flv.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (flv.js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

flv.js

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

This project, inspired by hls.js, 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 <video> element through Media Source Extensions API.

flv.js is written in ECMAScript 6, transpiled into ECMAScript 5 by Babel Compiler, and bundled with Browserify.

Features

FLV container with H.264 + AAC 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
Extermely low overhead, and hardware accelerated by your browser!

Build

npm install          # install dev-dependences
npm install -g gulp  # install build tool
gulp release         # packaged & minimized js will be emitted in dist folder

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

<video id="videoElement"></video>

        var flvPlayer = flvjs.createPlayer({
            type: 'flv',
            url: 'http://example.com/flv/video.flv'
        });
