Comment (by Dmitry Sinitsyn):

 What do you want to say?
 I'm talking about video PTS calculation:
 https://github.com/FFmpeg/FFmpeg/blob/b76a0e24f9effa64e48ff0567af0dc497dd99e84/libavdevice/dshow_pin.c#L316-L320

 Here we correctly get audio PTS by using IMediaSample_GetTime and create
 FAKE video PTS.
 Why?
