Doesn't work is too unspecific.

I'd assume that it's actually all though I am not sure about the C one.
However the only sensible way is to add a new implementation for higher bit depth.
I'd also like to make you aware of av_clip16, you should use that instead of the
If (v<0) v=0 ... code you have there.
