Comment (by nele):

 This thread helped me solve something I was working on, so here is what I
 did that you can duplicate in your code. The problem here is that frames
 here get packed so that you have I frame at the beginning, then two B
 frames and so on. The I frame's display time is actually shifted to the
 future so the B frame just behind it has to be displayed first. If you set
 the media_time to that frame's time, it should be just fine. For example,
 if I have 29.97 video, and my frames times are at 0/30000, 1001/30000,
 2002/30000 and so on, the media_time has to be set to 1001. Hope this
 helps. Cheers.
