Hi, I am about to create a filter which needs some lookahead and lookback (about 2 frames each). For the lookback, I could just save the old frame (is there a more efficient way than copying the data?), but what about the lookahead?
Is it possible to somehow access a future frame? The other possibility would be to delay a few frames, but how can I signal I have consumed a frame, but will not output any frame (yet) when the stream begins, and output several frames at the stream end?
