How to mix audios?

var audioMixer = new MultiStreamsMixer([microphone1, microphone2]);
 
// record using MediaRecorder API
var recorder = new MediaRecorder(audioMixer.getMixedStream());
 
// or share using WebRTC
rtcPeerConnection.addStream(audioMixer.getMixedStream());

How to mix screen+camera?

screenStream.fullcanvas = true;
screenStream.width = screen.width; // or 3840
screenStream.height = screen.height; // or 2160 
 
cameraStream.width = parseInt((20 / 100) * screenStream.width);
cameraStream.height = parseInt((20 / 100) * screenStream.height);
cameraStream.top = screenStream.height - cameraStream.height;
cameraStream.left = screenStream.width - cameraStream.width;
 
var mixer = new MultiStreamsMixer([screenStream, cameraStream]);
 
rtcPeerConnection.addStream(audioMixer.getMixedStream());
 
mixer.frameInterval = 1;
mixer.startDrawingFrames();
 
btnStopStreams.onclick = function() {
    mixer.releaseStreams();
};
 
btnAppendNewStreams.onclick = function() {
    mixer.appendStreams([anotherStream]);
};
 
btnStopScreenSharing.onclick = function() {
    // replace all old streams with this one
    // it will replace only video tracks
    mixer.replaceStreams([cameraStreamOnly]);
};

How to mix multiple cameras?

var mixer = new MultiStreamsMixer([camera1, camera2]);
 
rtcPeerConnection.addStream(audioMixer.getMixedStream());
 
mixer.frameInterval = 1;
mixer.startDrawingFrames();

API

  1. getMixedStream: (function) returns mixed MediaStream object
  2. frameInterval: (property) allows you set frame interval
  3. startDrawingFrames: (function) start mixing video streams
  4. resetVideoStreams: (function) replace all existing video streams with new ones
  5. releaseStreams: (function) stop mixing streams
