Mute/Unmute audio and video

By calling publisher.publishAudio() or publisher.publishVideo() method you can toggle audio and video. For these methods to have effect your Publisher object must have been initialized with audio: true and video: true respectively (see Publish a stream section).

publisher.publishAudio(audioEnabled);   // true to unmute the audio, false to mute it
publisher.publishVideo(videoEnabled);   // true to enable the video, false to disable it 
                                        // (a black screen will show up instead)
