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...
