Hi
divx5 and ffmpeg do add a userdata packet to each keyframe which contains the
version & build numbers ("DivX%db%d" and "FFmpeg%sb%s"), these are very
usefull to workaround encoder bugs, which sadly are much more common than
they should be
why doesnt xvid add such a thing to all keyframes?, iam asking because iam
currently rewriting the error resilience code in ffmpeg and for that the
correct padding is a nice indicator if some error near the end has happened,
and some old xvid versions had the padding wrong (AFIAK its correct now, but
i didnt check) anyway iam not completly sure how to autodetect that ...
