[FFmpeg-devel] [PATCH 5/6] avcodec/h264: mmx2, sse2, avx 10-bit h chroma intra deblock/loop filter

[James Darnley]

Yorkfield:
 - mmx2: 0.99x faster (180 vs. 181 cycles)
 - sse2: 1.05x faster (180 vs. 170 cycles)

Skylake:
 - mmx2: 1.21x faster (125 vs. 103 cycles)
 - sse2: 1.54x faster (125 vs.  81 cycles)
 - avx:  1.29x faster (125 vs.  97 cycles)
