Looks mostly correct. > -- If the timebase is the reciprocal of the framerate, a stream can be > delayed by x frames using setpts=PTS+x > -- In the more general case for arbitrary timebase and framerate, a stream > can be delayed by x frames using setpts=PTS+x/(FR*TB) "Delayed by x frame" is only relevant for a stream with constant frame per second. Please think first and foremost about timestamps and as little as possible in terms of number of frames. Regards, -- Nicolas George
