[MPlayer-dev-eng] [PATCH] altivec colorspace

[Marc Hoffman]

So does this solve what your trying to do?

#define vec_clip_for_ccir656(x) \
   vec_max (vec_min (x, (typeof(x))(235)), (typeof(x))(16))

#define vec_clip(x)  vec_clip_for_ccir656(x)

I'm curious why you care about this, I don't think the MAC's have such 
limitations on their output.
