Playing video in background of openGl application on iPhone

I found some tutorials about playing a fullscreen video on the iPhone, but I wond开发者_StackOverflower if it is possible to play an embedded movie in the background of a openGl animated app?

The movie should just loop seamlessly and should not have any control buttons like play/pause/volume popping up while being played. If possible, then how about performance?

3. Disable depth buffer reads/writes
4. Draw screen-sized textured quad using frame texture
5. Re-enable depth buffer reads/writes
6. Render your regular scene
7. Go to #1
