Realtime/Working WebRTC Experiments

1. It is a repository of uniquely experimented WebRTC demos; written by Muaz Khan!
2. No special requirement! Just Chrome (for desktop and android) or Firefox!
3. These demos/experiments are entirely client-side; i.e. no server installation needed!

DataChannel.js / A library for RTCDataChannel APIs

<script src="https://www.webrtc-experiment.com/DataChannel.js"></script>

var channel = new DataChannel('channel-name');

channel.onopen = function(e) {};
channel.onmessage = function(e) {};

// share with all participants
channel.send(file || data || 'text');

// Direct messages using user-ids
channel.userid = 'muazkh';
channel.channels['muazkh'].send(file || data || 'text');

=

RTCMultiConnection.js / A library for all WebRTC APIs

<script src="https://www.webrtc-experiment.com/firebase.js"> </script>
<script src="https://www.webrtc-experiment.com/RTCMultiConnection-v1.4.js"> </script>

<button id="init">Open New Connection</button><br />

<script>
    var connection = new RTCMultiConnection();

    connection.session = {
        audio: true,
        video: true
    };

    connection.onstream = function(e) {
        document.body.appendChild(e.mediaElement);
    };

    connection.onstreamended = function(e) {
        if (e.mediaElement.parentNode) e.mediaElement.parentNode.removeChild(e.mediaElement);
    };

    var session_unique_idetifier = 'Session Unique Identifier';

    connection.connect(session_unique_idetifier);

    document.getElementById('init').onclick = function() {
        this.disabled = true;
        connection.open(session_unique_idetifier);
    };
</script>

=

RTCall.js / A library for audio-only calling

<script src="https://www.webrtc-experiment.com/RTCall.js"></script>

var call = new RTCall();
call.onincomingcall = function(caller) {
   call.receive(caller.receiverid);
};
call.oncustomer = function(customer) {
   call.call(customer.callerid);
};

=

signaling for RTCMultiConnection-v1.4 and earlier releases

var SIGNALING_SERVER = 'http://domain.com:8888/';
connection.openSignalingChannel = function(config) {   
   var channel = config.channel || this.channel || 'one-to-one-video-chat';
   var sender = Math.round(Math.random() * 60535) + 5000;
   
   io.connect(SIGNALING_SERVER).emit('new-channel', {
      channel: channel,
      sender : sender
   });
   
   var socket = io.connect(SIGNALING_SERVER + channel);
   socket.channel = channel;
   
   socket.on('connect', function () {
      if (config.callback) config.callback(socket);
   });
   
   socket.send = function (message) {
        socket.emit('message', {
            sender: sender,
            data  : message
        });
    };
   
   socket.on('message', config.onmessage);
};

=

signaling using socket.io over node.js

Signaling for all latest experiments and newer releases.

Your server-side node.js code looks like this:

io.sockets.on('connection', function (socket) {
    socket.on('message', function (data) {
        socket.broadcast.emit('message', data);
    });
});

And to override openSignalingChannel on the client side:

connection.openSignalingChannel = function(callback) {
    return io.connect().on('message', callback);
};

Want to use XHR, WebSockets, SIP, XMPP, etc. for signaling? Read this post.

How to record audio using AudioVideoRecorder?

AudioVideoRecorder({

    // MediaStream object
    stream: MediaStream,

    // mime-type of the output blob
    mimeType: 'audio/ogg',

    // set time-interval to get the blob
    interval: 5000,

    // get access to the recorded blob
    onRecordedMedia: function (blob) {
        // POST/PUT blob using FormData/XMLHttpRequest

        // or readAsDataURL
        var reader = new FileReader();
        reader.onload = function (e) {
