Your patch works fine for me, I just had to change calls to mpglColorMask()
as I have green-magenta glasses and not the more common red-cyan.
I then tried with http://samples.mplayerhq.hu/3D/ANIXE3D.ts and I get a
fairly good 3D effect (as far as anaglyph goes) with a small amount of ghosting.
I think the color retainment is better though when using a more complex color
matrix, for example "optimized anaglyph" described here:
