Did you get any good result? Could you share your code? Thanks in advance. I am looking at it too. It seems there are a bunch of spaces to modify in order to let video output to an OpenGL texture. Just a little wondering why Google doesn't publish an example, since it seems many people ask the same question from my searching result.
