This is not quite true, and you said yourself that the palette isn't stored in
a host-specific order, Michael, since one has to use AV_RL32() to get the
palette entries correctly on a big-endian machine. Itt is stored BGRA, in that
order, in memory, as far as I understand.
1) pixfmt.h applies to AVFrame not AVPacket really, it can be a bit confusing
for raw formats that way though
Ah, OK. In any case I have noticed that you have to use AV_RL32() on a
big-endian machine to get the palette entries from the *packets* (sided
data or appended) in the right order.
