Turn camera capture on or off:

if(!isMutedCamera) {
    mAliRtcEngine.muteLocalCamera(true, AliRtcEngine.AliRtcVideoTrack.AliRtcVideoTrackCamera);
    mPublishVideoBtn.setText(R.string.resume_pub_video);

    mPublishVideoBtn.setText(R.string.stop_pub_video);
    isMutedCamera = false;
}

Remote listener callback:

@Override
public void onUserVideoMuted(String uid ,boolean isMute){
    handler.post(new Runnable() {
        @Override
        public void run() {

        }
    });
}

iOS

Turn camera capture on or off:

@IBAction func onVideoMuteSwitched(_ sender: UISwitch) {

        // Black frames
        rtcEngine?.muteLocalCamera(false, for: AliRtcVideoTrack.camera)
    } else {
        rtcEngine?.muteLocalCamera(true, for: AliRtcVideoTrack.camera)

Remote listener callback:
