flv.js  [![npm](https://img.shields.io/npm/v/flv.js.svg?style=flat)](https://www.npmjs.com/package/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.

## 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][].

[Media Source Extensions]: https://w3c.github.io/media-source/
[hls.js]: https://github.com/dailymotion/hls.js
[ECMAScript 6]: https://github.com/lukehoban/es6features
[Babel Compiler]: https://babeljs.io/
[Browserify]: http://browserify.org/

## 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
```bash
npm install --save flv.js
```

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

[cnpm](https://github.com/cnpm/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](docs/cors.md) for more details.

## Getting Started
```html
<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>
```

## 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](docs/livestream.md)

## Multipart playback
You only have to provide a playlist for `MediaDataSource`. See [multipart.md](docs/multipart.md)

## Livestream playback
See [livestream.md](docs/livestream.md)

## API and Configuration
See [api.md](docs/api.md)

## Debug
```bash
npm install          # install dev-dependences
npm install -g gulp  # install build tool
npm run dev          # with incremental compile and auto reload
```
