Comment (by reimar):

 I have been looking into a different strangeness, maybe that is even the
 deeper cause.
 The estimate_timings_from_pts function parses through the file a bit, then
 seeks back again to start reading again.
 The strange thing is, that the first pass through all the video packets
 get the right time stamps, they don't on the second. So obviously some
 state gets stuck in a bad state (possibly caused by this rather non-proper
 seeking).
 So possibly this bad state is actually the B-frames detection...
