[FFmpeg-devel] [PATCH] Port x264 SSE2 deblocking code to H.264 decoder

[Jason Garrett-Glaser]

Benchmarks on Cathedral:

	New	Old
	47.92	51.55
	47.86	50.83
	47.64	50.89
	47.97	51.11
	47.73	51.23
Average	47.83	51.12
Std Error	0.07	0.14
Average Percent Gain	6.89%	

Note the gain will probably be higher on modern CPUs that have fast
SSE2 units (Core 2, Phenom, Nehalem): this is from a Pentium 4.  I'm
doing tests on the P4 now since the Nehalem box, given previous
benchmarks, is obvious borked somehow.
