Interesting point. I suppose you mean backward seeking. Is that a valid
use case for a bitstream filter? Would it also apply to the standard
filter, where I took this code from?
I don't know, but I can try to add that, if required. Can you tell me
how to emulate or test seeking from the command line? Would I create a
file with backward jumps in PTS (and how)?
I also missed to bump libavcodec version, or to at least mention it,
BTW.
Thanks,
Moritz
