[FFmpeg-devel] [PATCH] palettized QuickTime video in Matroska, round 3

[Mats Peterson]

OK, Michael (among others), I have changed the name from get_qtpalette() 
to ff_get_qtpalette(). I've also added a *pb (AVIOContext) parameter to 
the ff_get_qtpalette() function, since one has to consume the full 
sample description when called from mov.c. This wasn't done before. In 
matroskadec.c, the sample description is already in the in-memory 
private data. It's beginning to get a bit kludgy, but I still think it's 
nice with a common palette handling function that is shared by both 
matroskadec.c and mov.c.

Original description of issue follows:

Palettized QuickTime video in Matroska has hitherto not been recognized 
whatsoever, and the "palette" used has been completely random.

The patch for matroskadec.c fixes this issue by adding a palette side 
data packet in matroska_deliver_packet(), much in the same way as it's 
done in mov.c.

The change to mov.c consists mainly of moving the palette handling from 
the mov_parse_stsd_video() function to a new get_qtpalette() function in 
the new file qtpalette.c, which is shared by both matroskadec.c and mov.c.

In matroskadec.c, I'm also putting the palette in 'extradata', like it's 
done for V_MS/VFW/FOURCC; this is a requirement in order for MPlayer to 
recognize the palette.
