Sending video and audio stream to server

问题

I am trying to develop a system where there are two clients that can video chat to each other from their browsers over a server. First client sends its video stream to the server and the server sends it to the second client. Also, server saves client's stream as a video file.

I used this WebRTC example: https://github.com/webrtc/samples/blob/master/src/content/getusermedia/source/js/main.js

Server side;

var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.use(express.static('C:/source/'));
app.get('/', function(req, res) {
    res.sendFile('C:/source/index.html');
});

io.on('connection', function(socket) {
    console.log('user connected.');

    socket.on('disconnect', function() {
        console.log('user disconnected.');
    });

    socket.on('chat message', function(msg) {
        ?
    });
});

http.listen(3000, function(){
  console.log('listening on *:3000');
});

Client side;

var socket = io();

while(streaming) {
   socket.emit(?);
}

I can't understand that from which source I should emit the video + audio stream of the client to the server. If I successfully upload the stream, I will be able to handle it on server side.

回答1:

You will need a server that is capable of processing WebRTC media.

I suggest looking into Kurento, Janus, Jitsi Videobridge, FreeSWITCH and Asterisk as alternatives.

This will require a lot more effort from your end, as all will necessitate learning more about them, WebRTC and real-time media processing.

If you need this working yesterday and want to put your efforts and focus elsewhere, you should check out some of the vendors listed in this report about WebRTC PaaS.
