Use the scale gesture to seek in a MTMovieClip - MT4j

Tutorial: Create standalone MT4j applications > Use direct OpenGL calls to draw > Use the scale gesture to seek in a MTMovieClip

To seek in a MTMovieClip we normally use the seek bar at the bottom. To shake things up a little, we could also use the scale gesture to seek so that if we move the 2 fingers closer together we would seek to the start of the movie and if we spread our fingers we would seek towards the end of the movie.
Here's a way to do it:

final MTMovieClip clip3 = new MTMovieClip("someVideo.mp4", new Vertex(300, 300), 30 ,pa);
		 clip3.removeAllGestureEventListeners(ScaleProcessor.class);
		 clip3.registerInputProcessor(new ScaleProcessor(getMTApplication()));
		 clip3.addGestureListener(ScaleProcessor.class, new IGestureEventListener() {
			 public boolean processGestureEvent(MTGestureEvent ge) {
				 ScaleEvent se = (ScaleEvent)ge;
				 delta += (se.getScaleFactorX() -1.0f) ;
				 if (se.getId() == ScaleEvent.GESTURE_DETECTED){
					 delta = 0.0f;
					 startTime = clip3.getVideoTexture().getTime();
					 clip3.getVideoTexture().pause();
				 }
				 else if (se.getId() == ScaleEvent.GESTURE_UPDATED){
					 if (se.getScaleFactorX() != 1.0f){
						 clip3.getVideoTexture().jump(startTime + delta * 50); //this can be tweaked
					 }
				 }
				 else if (se.getId() == ScaleEvent.GESTURE_ENDED){
					 delta = 0.0f;
					 clip3.getVideoTexture().play();
				 }
				 return false;
			 }
		 });
