[FFmpeg-devel] [PATCH] VC-1: Faster C loopfilter

[Jason Garrett-Glaser]

Yuvi requested I optimize this one, so I did.  This patch can be
summed up as follows:

13:20 <@mru> I see a lot of xor
13:20 <@mru> that's usually a sign of magic

338 -> 315 cycles for vc1_loop_filter on Core 2 Duo.
Overall decoding 12.047s -> 11.781s
