Non-realtime video processing? (Read 964 times)

Non-realtime video processing?
Aug 25th, 2009, 11:47am  
Is there a way to do non-realtime video processing using Processing's video-related classes? Ideally, I'd like to be able to read frames from a video file sequentially, without skipping any, regardless of whether this alters the playback speed. Thanks.

Yeah, but the problem is, I can't figure out how to tell an instance of Movie to give me frame # x -- i.e., I'd like to be able to do something like "movie.getFrame(1); movie.getFrame(2), ..." etc. All I can do is read whatever frame is currently available and hope that I'm able to do my processing on it before the next frame -- otherwise, I'll get dropped frames. Granted, I can slow down playback with the speed() function, but that seems like a bit of a kludge...
