switch camera using MediaDevices.getUserMedia() in webrtc

Question

I am trying navigator.MediaDevices.getUserMedia() webrtc to switch the device camera during the call. This functionality is working fine on the desktop browser but on mozilla android it is not working. Here is my code that i am using .

var front=false;

var myConstraints = {  video: { facingMode: (front? "user" : "environment")} }; 
navigator.mediaDevices.getUserMedia(myConstraints).then(function(stream) {

}

any idea about this??

Answer 1

Phone hardware typically doesn't allow opening both the front and back camera at the same time. Change your code to stop() the existing stream before getting the other camera.

See my answer to a similar question for a working example.

Answer 2

use the last version of adapter.js and see if NotReadableerror is happening, it seems that Chrome for android cannot release front camera hardware to switch to rear by using stream.getVideoTracks()[0].stop(); I think it could be a bug
