Hello list,

When I convert an yuv pixel into rgb using the recipies in
http://www.fourcc.org/fccyvrgb.php I get an accurate color conversion
but the contrast seems to be decreased. If i write, e.g., the pixel
directly into an sdl yuv_overlay, I get a well-contrasted frame,
however, if I convert the pixel to rgb and call SDL_MapRGB, I get a
contrast-decreased frame.
