In case this patch got lost in my endless stream of previous posts, I'll
repost it. Description of the patch follows:
In order to make MPlayer use the correct palette when playing palettized
QuickTime video in Matroska, the palette will need to be copied to
st->codec->extradata in matroskadec.c. As I have explained so many times
before, for some inexplicable reason, MPlayer in its current state adds
*another* palette side data packet *after* the one added in
matroskadec.c, using whatever is in extradata as the palette.
Since this copying to st->codec->extradata is done for V_MS/VFW/FOURCC,
I see no reason why it couldn't be done for V_QUICKTIME as well. I have
yet to see any program use the extradata for anything else than the
palette when it comes to palettized video in Matroska. I might be wrong,
of course.
If this patch is not acceptable, we'll have to tell the MPlayer
maintainers to fix this extraneous addition of yet another palette side
data packet. Unfortunately, in my experience, they seem rather slow on
reacting. I would therefore be grateful if someone of the more
"influential" persons here could bring this issue up in their community.
Sample palettized Matroska files for testing are available at

Well, what do you know. It seems the issue has already been fixed in
MPlayer. I just recompiled it with the latest FFmpeg. Black magic.
Forget this patch then.
