Realtime/Working WebRTC Experiments

1. It is a repository of uniquely experimented WebRTC demos; written by Muaz Khan!
2. No special requirement! Just WebRTC compatible web-browser (e.g. chrome/firefox/opera on desktop/android)
3. These demos/experiments are entirely client-side; i.e. no server installation needed!
4. You can use all these demos in PHP/Python/Ruby/ASP.NET/etc. everywhere!

RTCMultiConnection.js

You can write entire skype-like web-app using RTCMultiConnection! It supports all complex renegotiation scenarios!

<button id="openNewSessionButton">open New Session Button</button><br />

<script src="//cdn.webrtc-experiment.com/RTCMultiConnection.js"> </script>
<script>
var connection = new RTCMultiConnection().connect();
document.getElementById('openNewSessionButton').onclick = function() {
    connection.open();

<script>
    var channel = new DataChannel();
    channel.onopen = function(userid) {};
    channel.onmessage = function(message) {};
	
    // search for existing channels

Translator.js / Demo

Translator.js is a JavaScript library built top on Google Speech-Recognition & Translation API to transcript and translate voice and text. It supports many locales and brings globalization in WebRTC!

<script src="//cdn.webrtc-experiment.com/Translator.js"> </script>

var translator = new Translator();

translator.voiceToText(function (text) {
    console.log('Your voice as text!', text);
}, 'your-language');

translator.translateLanguage(textToConvert, {
    from: 'language-of-the-text',
    to: 'convert-into',
    callback: function (translatedText) {
        console.log('translated text', translatedText);
    }
});

translator.speakTextUsingRobot(textToPlay);

translator.speakTextUsingGoogleSpeaker({
    textToSpeak: 'text-to-convert',
    targetLanguage: 'your-language'
});

getScreenId.js / Demo

Simply use getScreenId.js and enjoy screen capturing from any domain. You don't need to deploy chrome extension yourself. You can refer your users to install this chrome extension instead. Also, getScreenId.js auto-fallbacks to command-line based screen capturing if chrome extension isn't installed or disabled. getScreenId.js throws clear exceptions which is helpful for end-user experiences.

Demo: https://www.webrtc-experiment.com/getScreenId/

<script src="//cdn.WebRTC-Experiment.com/getScreenId.js"></script>

<script>
getScreenId(function (error, sourceId, screen_constraints) {
    // error    == null || 'permission-denied' || 'not-installed' || 'installed-disabled' || 'not-chrome'
    // sourceId == null || 'string'

    navigator.webkitGetUserMedia(screen_constraints, function (stream) {
        document.querySelector('video').src = URL.createObjectURL(stream);
    }, function (error) {
        console.error(error);
    });
});
</script>

openSignalingChannel for RTCMultiConnection.js and DataChanel.js (Client-Side Code)

var onMessageCallbacks = {};
var socketio = io.connect('http://localhost:8888/');

socketio.on('message', function(data) {
    if(data.sender == connection.userid) return;
    
    if (onMessageCallbacks[data.channel]) {
        onMessageCallbacks[data.channel](data.message);
    };
});

connection.openSignalingChannel = function (config) {
    var channel = config.channel || this.channel;
    onMessageCallbacks[channel] = config.onmessage;

    if (config.onopen) setTimeout(config.onopen, 1000);
    return {
        send: function (message) {
            socketio.emit('message', {
                sender: connection.userid,
                channel: channel,
                message: message
