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 mozil

Answer 1

Webcam.set({
        width: 490,
        height: 450,
        image_format: 'jpeg',
        jpeg_quality: 90,
        constraints: {
                    facingMode: {
                                  exact: 'environment'
                                  }

                }   
    });

This code is working for all browsers.

constraints: {facingMode: { exact: 'environment' }} 

Above line is responsible to open rear camera, set constraints : null to open front camera. you can also adjust this code by implementing "switch camera" button method
