WebRTC Using back camera instead of front camera

Question

I use simplewebrtc.com's webrtc solution (see https://simplewebrtc.com/demo.html). When you join the room the front camera will be used. But i want to use back camera. There is info page (see "Selecting a microphone and camera" at https://simplewebrtc.com/notsosimple.html ) for that but i couldn't implement it. Could anybody help me please?

first: In webrtc i think this should be handled in constraints passed to getUserMedia.

 { audio: true, video: { facingMode: { exact: "environment" } } }

you can log the lable of the using video device in browser's console:

  var videoTracks = localStream.getVideoTracks();
  if (videoTracks.length > 0) {
    trace('Using video device: ' + videoTracks[0].label);
  }

second: In browser's setting you can set default camera, e.g. in chrome go to Settings>Advanced>Content Settings>Camera

There is no option to select the camera in Chrome settings. I couldn't implement your code. Where should i add it? – Cenk Ten Sep 06 '17 at 13:45
The localStream variable in the code is the stream returned from getUserMedia. – Ali Abdollahi Sep 10 '17 at 06:51
