Yet another probesize used to get the durations when estimate_timings_from_pts is required. It is aimed at users interested in better durations probing for itself, or because using avformat_find_stream_info indirectly and requiring exact values: for concatdec for example, especially if streamcopying above it. The current code is a performance trade-off that can fail to get video stream durations in a scenario with high bitrates and buffering for files ending cleanly (as opposed to live captures): the physical gap between the last video packet and the last audio packet is very high in such a case. Default behaviour is unchanged: 250k up to 250k << 6 (step by step). Setting this new option has two effects: - override the maximum probesize (currently 250k << 6) - reduce the number of steps to 1 instead of 6, this is to avoid detecting the audio "too early" and failing to reach a video packet. Even if a single audio stream duration is found but not the other audio/video stream durations, there will be a retry, so at the end the full user-overriden probesize will be used as expected by the user.
