Seungha Yang ba26a5aea8 mfvideoenc: Enhance B-frame timestamp handling 
When B-frame is enabled, encoder seems to adjust PTS of encoded sample
by using frame duration.

For instance, one observed timestamp pattern by using B-frame enabled
and 30fps stream is:
* Frame-1: MF pts 0:00.033333300 MF dts 0:00.000000000
* Frame-2: MF pts 0:00.133333300 MF dts 0:00.033333300
* Frame-3: MF pts 0:00.066666600 MF dts 0:00.066666600
* Frame-4: MF pts 0:00.099999900 MF dts 0:00.100000000

We can notice that the amount of PTS shift is frame duration and
Frame-4 exhibits PTS < DTS.

To compensate shifted timestamp, we should
calculate the timestamp offset and re-calculate DTS correspondingly.
Otherwise, total timeline of output stream will be shifted, and that
can cause time sync issue.
