[FFmpeg-devel] [PATCH] PhotoCD image decoder

Hi all,

this is a port of the libpcd PhotoCD image decoder 
(http://linux.bytesex.org/fbida/libpcd.html 
<http://linux.bytesex.org/fbida/libpcd.html>). Libpcd is GPL. The author 
has agreed to me (by private email) to relicense his parts to LGPL.

I'm still having trouble getting the colorspace conversion to RGB right. 
The format uses a colorspace as described here:

<http://www5.informatik.tu-muenchen.de/lehre/vorlesungen/graphik/info/csc/COL_34.htm>
Is there a way FFmpeg can do this conversion or will I have to do it 
manually in the decoder?

PhotoCD is a multiresolution format; users can set avctx->lowres to 1, 2 
or 3 to access the lower resolutions.

Samples may be found at ftp://ftp.kodak.com/www/images/pcd/

Best Regards,
