I've noticed that avienc.c is close to useless for use with stdout. It
only checks pb->seekable in a few places, and for example the
ff_end_tag() function uses avio_seek(), but that one is used in several

Anyway, this version adds the AVISF_VIDEO_PALCHANGES flag properly to
the 'strh' chunk, per the Microsoft documentation.

The original toon.avi doesn't contain xxpc chunks at keyframes either,
if that can be of any comfort. It only contains two xxpc chunks, at
that. If you're able to invent something nice regarding palette changes
on keyframes, please go ahead. But please add what's available in the
meantime.

In my book it should be up to the demuxer/decoder to keep track of
previous palettes. You said yourself that no xxpc chunks should be
included if they are identical to the first palette.

Mats


Or previous palette, rather.
