Can I create a blue-screen effect with MPMoviePlayerController?

I am showing a video inline (not fullscreen) using MPMoviePlayerController. I am using this class because it is the only player I got working using a remote file (progressive download) and not a local file.

Is there any way to create a blue-screen effect? wha开发者_JAVA百科t I basically mean is decide on a certain RGB value and set that pixel's alpha to 0. Is it possible to perform any image processing per frame with MPMoviePlayerController?

You can not use MPMoviePlayerController for such movie processing.

Still, there is ways to accomplish what you are asking for. You may use the AVAssetWriter etc.
