I've tried it on Ubuntu and it works well. I have two questions:
1. The script above saves the frame based on how much time has passed.
Is it also possible to access the frames of a movie one by one
independent of time? So that I can access precisely frame[0], frame[1],
..., frame[n] independent of the framerate?
2. For me the speed is the most important. What is generally faster: the
roundtrip through the videocard or pyglet.media.avbin.AVbinSource?
