* if flags contain AVSEEK_FLAG_FRAME then all timestamps are in frames
* in the stream with stream_index (this may not be supported by all demuxers).
* else all timestamps are in units of the stream selected by stream_index or
* if its -1 AV_TIME_BASE units.
* if flags contain AVSEEK_FLAG_ANY then non keyframes are treated as
