No. those numbers does not relate to Media Sample PTS.
IMediaSample::GetTime returns stream times at which this sample should
begin and finish.
There are two available cases: times are good or times are absent.
Whole DirectShow based on these timestamps.
So I'm still against of ignoring video timestamps in that place of libav.
We must get timestamps directly by IMediaSample::GetTime.
May be we should be able to revert to old way, but normal way should be:
IMediaSample::GetTime for all samples, if time==NULL, then use reference
clock.
