 Summary of the bug:
 How to reproduce:
 Create blankclip 3600 frames long with time and frame number hardcoded in
 it.  Cut at I-frame 1850 (GOP 50).

 FFprobe states the video starts at complete frame 1852 'B' frame but all
 video viewers all show 1850 I-frame . FFprobe also states first frame is
 time code pkt_pts_time is 0.000000 and 'B' frame.

 Creating -F image2 will create nothing but frame 1852.

 How can this be correct if players show frame 1850 and 1851 starting?
