Examples

In the following example, VideoDisplay and MediaPlayer instances are created. The VideoDisplay instance is positioned and added to the stage. It is then associated with the MediaPlayer object using the videoDisplay property:

            _myVD = new VideoDisplay;
            _myVD.setPosition(1024/2 - 800/2, 600/2 - 480/2);
            _myVD.setSize(800, 480);
            _myVD.backgroundColor = 0x000000;
            addChild(_myVD);
            
            _myPlayer = new MediaPlayer();
            _myPlayer.addEventListener(MediaPlayerEvent.INFO_CHANGE, infoChange);            
            _myPlayer.url = "/accounts/1000/shared/videos/Vancouver City.mp4"            
            _myPlayer.videoDisplay = _myVD;
