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!

How to use?

Each demo has a unique directory. Simply download that directory, upload in your webserver and use it; and it'll work!

You don't need to modify any single line to use it. No single installation or modification is needed :)

How to record audio using RecordRTC?

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

Documentation page: http://recordrtc.org/RecordRTC.html

var recordRTC = RecordRTC(mediaStream, {
    type: 'video' // audio or video or gif or canvas
});

recordRTC.startRecording();

recordRTC.stopRecording(function(videoURL) {
    video.src = videoURL;
    
    var blob = recordRTC.blob;
    var arrayBuffer = recordRTC.buffer;
    recordRTC.getDataURL(callback_function);
});

RTCMultiConnection.js

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

<button id="openRoom">Open Room</button>
<button id="joinRoom">Join Room</button><br />

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

DataChannel.js / A library for RTCDataChannel APIs

<script src="//cdn.webrtc-experiment.com/DataChannel.js"> </script>
<script>
    var datachannel = new DataChannel();
    datachannel.onopen = function(remoteUserid) {};
    datachannel.onmessage = function(message, remoteUserid) {};
	
    // search for existing channels
    datachannel.connect();

    document.getElementById('new-channel').onclick = function() {
        datachannel.open(); // setup new channel
    };
</script>

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'
});

FileBufferReader.js / Demo

FileBufferReader is a JavaScript library reads file and returns chunkified array-buffers. The resulting buffers can be shared using WebRTC data channels or socket.io.

var fileBufferReader = new FileBufferReader();

fileBufferReader.readAsArrayBuffer(file, function(uuid) {
    // var file         = fileBufferReader.chunks[uuid];
    // var listOfChunks = file.listOfChunks;
    
    // get first chunk, and send using WebRTC data channels
    // NEVER send chunks in loop; otherwise you'll face issues in slow networks
    // remote peer should notify if it is ready for next chunk
    fileBufferReader.getNextChunk(uuid, function(nextChunk, isLastChunk) {
        if(isLastChunk) {
            alert('File Successfully sent.');
        }
        // sending using WebRTC data channels
        datachannel.send(nextChunk);
    });
});

datachannel.onmessage = function(event) {
    var chunk = event.data;
    
    if (chunk instanceof ArrayBuffer || chunk instanceof DataView) {
        // array buffers are passed using WebRTC data channels
        // need to convert data back into JavaScript objects
    
        fileBufferReader.convertToObject(chunk, function(object) {
            datachannel.onmessage({
                data: object
            });
        });
        return;
    }
    
    // if you passed "extra-data", you can access it here:
    // chunk.extra.senderUserName or whatever else
    
    // if target peer requested next chunk
    if(chunk.readyForNextChunk) {
        fileBufferReader.getNextChunk(chunk.uuid, function(nextChunk, isLastChunk) {
            if(isLastChunk) {
                alert('File Successfully sent.');
            }
            // sending using WebRTC data channels
            datachannel.send(nextChunk);
        });
        return;
    }
    
    // if chunk is received
    fileBufferReader.addChunk(chunk, function(promptNextChunk) {
        // request next chunk
        datachannel.send(promptNextChunk);
    });
};

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.

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

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