[MPlayer-users] How to invert video colors (Windows)?

[Keith]

Hi!

My beamer inverts all colors, besides that it perfectly works. I now 
want to supply it with an inverted signal, then the projection is fine. 
That already works with pictures.

For video I want to use mplayers filter functionality. I tried 
"eq2=1:-1" but that seams not to be the correct color inversion... It is 
ok with grayscales but colors are not inverted as they should.

Any ideas?

Best regards
Keith
