Lavf doesn't put the palette where our raw decoder expects it
in that case.
I'll make the FFmpeg one the default for paletted formats,
it probably will work better anyway at least in those cases.
Though I'll have to add that I think this file is an abomination,
it uses the quicktime wrapping format to store raw video, so
it's basically a mov file in a MKV file!
Either MKV does not support paletted raw natively, then
it should be added, or it does and then the program
that created this should be considered broken.
