I don't follow. If the inversion was a mistake, then frames currently
not marked by demuxer are in fact keyframes and a stream decoded from
that frame onwards should show correct output. I see precisely the
opposite. Output generated by streamcopying from currently marked KF
decode correctly and those generated by streamcopying from currently
marked non-KF decode incorrectly*.
This should rule out errors in the muxer as well.
* ffmpeg -i logo-capcom.cpk -ss 5.4 -c copy -copyinkf -an copy-test.cpk
&& ffplay copy-test.cpk
It's very much possible I'm missing something but I don't see what.
