Comment (by cehoyos):

 Replying to [comment:27 kierank]:
 > What pixel format are they (YUV, RGB, ???) - nothing looks correct so
 far. There appears to be 4 planes though and I don't understand how a film
 scanner can scan alpha.

 If it is a Bayer format, please look at AV_PIX_FMT_BAYER_BGGR8 and
 AV_PIX_FMT_BAYER_BGGR16 and their friends. If it is CMYK, you will find a
 conversion routine in mjpegdec.c. But in any case, if you have a patch
 that produces a recognizable image with wrong colours (and resolution)
 please post it, others could improve it.
