Michael, since before I started messing with the QuickTime palette, the
palette has usually been used in conjunction with AVI, which uses little
endian order of the entries (BGRA), here is a proposed patch that forces
little-endian order when storing the QuickTime palette, in case the
movenc.c patch won't work with "ffmpeg -i 8bpp_129.mov -vcodec rawvideo
out.mov" on that mips machine, which I suspect will be the case without
knowing beforehand.
