Installation

How to use library

Install NPM modules

Python 2, make, g++ or clang are required for installing mediasoup.

$ npm install mediasoup-server

Run WebRTC server

const WebRtcServer = require('mediasoup-server').WebRtcServer;

const hostname = os.hostname();

const webRtcServer = new WebRtcServer();
webRtcServer
.listen({
	enableDebug: true,
	key: fs.readFileSync('keys/server.key'),
	cert: fs.readFileSync('keys/server.crt'),
	port: 3888,
	path: 'public',
})
.on('listen', () => {
	console.log('Mediasoup demo started');
})
.on('web-listen', (port) => {
	console.log(`Open https://${hostname}:${port} with browser`);
})
.on('new-connection', (connection) => {
	console.log(`New connection [${connection.id}]`);
	
	connection
	.on('error', (err) => {
		console.log(`Connection [${connection.id}] error: ${err}`);
	})
	.on('receive', (action, data) => {
		console.log(`Connection [${connection.id}] receive [${action}]`);
	})
	.on('send', (action, data) => {
		console.log(`Connection [${connection.id}] send [${action}]`);
	})
	.on('new-stream', (stream) => {
		console.log(`Connection [${connection.id}] peer [${stream.peer.id}] new stream [${stream.id}]`);
	})
	.on('ready', (peerConnection) => {
		console.log(`Connection [${connection.id}] peer [${peerConnection.peer.id}] ready`);
	})
	.on('close', (peerId) => {
		console.log(`Connection [${connection.id}] peer [${peerId}] closed`);
	})
	.on('disconnect', (err) => {
		console.log(`Connection [${connection.id}] signaling disconnected`);
		connection = null;
	});
});

Run RTSP server

const RtspServer = require('mediasoup-server').RtspServer;

const rtspServer = new RtspServer(webRtcServer);
rtspServer
.listen(5000)
.on('listen', (port) => {
	console.log(`RTSP server started rtsp://${hostname}:${port}`);
})
.on('new-source', (source) => {
	let rtspUrl = `rtsp://${hostname}:${rtspServer.port}/${source.id}.sdp`;
	source.on('enabled', () => {
		console.log(`RTSP source available: ${rtspUrl}`);
	});
});

Record to disc

const rtspServer = new RtspServer(webRtcServer);
rtspServer
.listen(5000)
.on('new-source', (source) => {
	source.on('enabled', () => {
		let rtspUrl = `rtsp://${hostname}:${rtspServer.port}/${source.id}.sdp`;
		let filepath = `${recordingsPath}/${source.id}.mp4`;
		let logpath = `${recordingsPath}/${source.id}.log`;
		
		console.log(`Recording [${source.id}]: ${filepath}`);
		let process = streamer.record(rtspUrl, filepath, logpath)
		.on('error', (err) => {
			console.error(`Streamer [${source.id}] error: ${err}`);
		})
		.on('exit', (code, signal) => {
			console.log(`Streamer [${source.id}] closed, log: ${logpath}`);
		});
	});
});

Publish to RTMP server

const rtspServer = new RtspServer(webRtcServer);
rtspServer
.listen(5000)
.on('new-source', (source) => {
	source.on('enabled', () => {
		let rtspUrl = `rtsp://${hostname}:${rtspServer.port}/${source.id}.sdp`;
		let rtmpUrl = `rtmp://${hostname}:1935/live/${source.id}`;
		let logpath = `${recordingsPath}/${source.id}.log`;
		
		console.log(`Publishing [${source.id}]: ${rtmpUrl}`);
		let process = streamer.publish(rtspUrl, rtmpUrl, logpath)
		.on('error', (err) => {
			console.error(`Streamer [${source.id}] error: ${err}`);
		})
		.on('exit', (code, signal) => {
			console.log(`Streamer [${source.id}] closed, log: ${logpath}`);
		});
	});
});

How to use example

Git clone

git clone https://github.com/tan-tan-kanarek/mediasoup-server.git
cd mediasoup-server/

Install NPM modules

Python 2, make, g++ or clang are required for installing mediasoup.

$ npm install

Run server example

$ node example

or

$ npm start

access with borwser

• Open http://localhost:3888/.
• Set room name and click [Join] button

TODO

Server

• Execute ffmpeg remotely (send message to different server to execute ffmpeg)
• To support scalability and redundancy, hold list of rooms in all servers and redirect socket.io commands to the server that handles the room, SDPs should be generated on the server that holds the room.

Client

• Rejoin room when socket.io reconnected.
• Accept new room created event.
