Here's an interesting one. Windows Media Player won't make any palette 
changes without the xxpc chunks beeing indexed.

Fixing the logic for reading and seeking with xxpc chunks in the demuxer 
is a future task. Now the muxing of video with xxpc chunks works 
properly at least.

Try playing the resulting test.avi file from the command line below with 
Windows Media Player, with and without patch 2/3 and 3/3 (you'll need 
patch 1/3 in order to get the xxpc chunks properly in the demuxer).

ffmpeg -i TOON.AVI -c:v copy -c:a copy test.avi
