* in AVI, WRAW is paletted 8-bit
* in MOV, it means Windows RAW and it means rawvideo stream, the exact
format depends on pix_fmt_bps_mov.
Or maybe WRAW in AVI is rawvideo as well (according to
pix_fmt_bps_mov), but the only analyzed sample was paletted so we
didn't check on pix_fmt_bps_avi.
As for the flipping, I have no ideas nor samples, so I don't know when
we're assumed to flip it, according to Michael:
|all rgb should be fliped unless height<0 or so IIRC
Also should it be RGB or BGR?
I couldn't find relevant information, nor in fourcc.org.
