They also seem to have taken alot of feedback on quicktime, completely re-written the API, so now you can make a video player in interface builder with no code whatsoever, and you can do cool stuff like map H.264 onto a surface as a texture, and do anything else with that surface that you chould normally do in OpenGL, I'm assuming you can also map CoreImage filters ontop of this either as a texture filter or for the whole scene.
