[MPlayer-dev-eng] [PATCH] YellowBlue/AmberBlue Dubios support for stereo3d

[Bob]

Hi,
I've patched stereo3d filter to support amber/blue least-square/dubois 
(eric dubois) filter as specified on:
http://www.flickr.com/photos/e_dubois/5230654930/ and 
http://www.site.uottawa.ca/~edubois/anaglyph/

The settings numbers have been converted by taking the 
numbers*65535/1062, and it works for me(TM).
Tinkering with this filter, I realized that there is most likely a large 
room for improvement in speed and gama/hue corrections, but works for 
simple material.
Most likely it could be done a ton better by using hue tables, but 
unfortunately ColorCode 3D has some rather nasty patents that shouldn't 
be tripped over..
If anyone have ideas on how to implement good gamma & hue corrections 
without tripping over US Patent 6,687,003 and EPO 1131658, I'll gladly 
try to implement it...
