HTML5 RTSP Player

Overview

html5_rtsp_player.js is a Javascript library which implements RTSP client for watching live streams in your browser that works directly on top of a standard HTML element. It requires support of HTML5 Video with Media Sources Extensions for playback. Also player relies on server-side websocket proxy for retransmitting RTSP streams to browser.

It works by muxing RTP h.264 payload into ISO BMFF (MP4) fragments.

html5_rtsp_player.js is written in ECMAScript6, and transpiled in ECMAScript5 using Babel.

Install

npm install git://github.com/SpecForge/html5_rtsp_player.git

Usage

Browser side

Attach HTML Video with RTSP URL

<video id="test_video" controls autoplay src="rtsp://your_rtsp_stream/url"></video>

Setup player in your js:

import * as rtsp from 'rtsp_player';

rtsp.RTSP_CONFIG['websocket.url'] = "ws://websocket_proxy_address/ws"; // You should specify address of proxy described below

let player = rtsp.attach(document.getElementById('test_video'));

ES6 Modules support is required. You can use webpack with babel loader to build this script:

webpack.config.js

const PATHS = {
    src: {
        test: path.join(__dirname, 'test.js')
    },
    dist: __dirname
};

module.exports = {
    entry: PATHS.src,
    output: {
        path: PATHS.dist,
        filename: '[name].bundle.js'
    },
    module: {
        loaders: [
            {
                test: /\.js$/,
                loader: 'babel',
                query: {
                    presets: ['es2015', 'stage-3', 'stage-2', 'stage-1', 'stage-0']
                }
            }
        ]
    },
    resolve: {
        alias: {
            rtsp: path.join(__dirname,'node_modules/html5_rtsp/src')
        }
    }
};

> npm install bp_event bp_log bp_statemachine
> webpack --config webpack.config.js

Include compiled script into your HTML:

<script src="test.bundle.js"></script>

Server side

1. Install websocket proxy

   For Debian-based systems:

   curl -o- http://repo.tom.ru/rpm/websockrtsprepo-1-0.deb | dpkg --install 
   apt install websockrtspproxy # Debian-based systems
   

   or Fedora:

   dnf install http://repo.tom.ru/rpm/websock_rtsp_repo-1-0.noarch.rpm
   dnf install websock_rtsp_proxy
   

2. Configure port in /etc/ws_rtsp.ini

   This port should be open in your firewall. Also you can pass request to this port from your proxy. (for example: http://nginx.org/en/docs/http/websocket.html)

3. Run it

> service ws_rtsp start
