Comment:
For the attached sample, I can reproduce a regression since
3166a6fc379789b3782f431dd232033c2069c443:
Seeking 10 seconds forwards and backwards a few times (making sure that
backwards seeking always ends at about 2 seconds) suddenly seeks to 24
seconds (instead of the usual 12), this can be reproduced another time.
The behaviour cannot be seen with older versions. The same behaviour can
be seen when changing "left" and "right" to +5 and +5 seconds: Instead of
seeking to around 8 seconds (after seeking back to 2 or 3), forward
seeking again ends at 24 seconds.

[mpeg4 @ 0x7f990c013220] Video uses a non-standard and wasteful way to
store B-frames ('packed B-frames'). Consider using the
mpeg4_unpack_bframes bitstream filter without encoding but stream copy to
fix it.
