[Android WebRTC] How to switch camera while call is active.

[Albert Devesa Triscon]

Hi,

I'm developing a Android WebRTC application based on AppRTCDemo and I wanted to switch camera while call is active. What I have done without sucess was removeStream of the peer connection, then get the new VideoCapturer from the other camera and addStream to the peer. Here I leave you the code:

public void switchCamera(String cameraFacing, String height, String width){

                Peer peer = peers.get(socketIDExt);

                peer.pc.removeStream(lMS);

                mListener.onRemoveLocalStream(lMS, peer.endPoint);

                MediaConstraints videoConstraints = new MediaConstraints();

                videoConstraints.mandatory.add(new MediaConstraints.KeyValuePair("maxHeight", height));

                videoConstraints.mandatory.add(new MediaConstraints.KeyValuePair("maxWidth", width));

                camera = getVideoCapturer(cameraFacing); //here I get the "Failed to open capturer" exception and the app crashes

                //the code will go on here

        }

When I'm about to get the new VideoCapturer the app crashes. I think I can't get the new VideoCapturer because I have to get rid of the actual VideoCapturer (which I don't know how to do it).

Does anyone know how to solve it?

Thanks,

Albert

I forgot to publish the getVideoCapturer method:

private VideoCapturer getVideoCapturer(String cameraFacing) {

int[] cameraIndex = { 0, 1 };

int[] cameraOrientation = { 0, 90, 180, 270 };

for (int index : cameraIndex) {

for (int orientation : cameraOrientation) {

String name = "Camera " + index + ", Facing " + cameraFacing +

", Orientation " + orientation;

VideoCapturer capturer = VideoCapturer.create(name);

if (capturer != null) {

return capturer;

}

}

}

throw new RuntimeException("Failed to open capturer");

}
