[FFmpeg-devel] [PATCH] Use signed version when putting and clamping pixels in VC-1

[Christophe GISQUET]

Hi,

trivial patch for P and B frames cases, roughly 2% speed-up (with the MC
patch applied, otherwise it'd have been less impressive :)

I frames can also benefit for the same optimization, but this seems only
conditional (probably needing adapting more deeply other functions).
Therefore I think it would belong to another patch.

Best regards,
