2016-01-13Revert "Merge "Change highbd variance rounding to prevent negative variance.""Alex Converse
This reverts commit ea48370a500537906d62544ca4ed75301d79e772, reversing changes made to 15939cb2d76c773950cda40988ede89e111872ea. The commit was insufficiently tested and causes failures. Change-Id: I623d6fc2cd3ae6fd42d0abab1f8eada465ae57a7
2015-11-24Change highbd variance rounding to prevent negative variance.Alex Converse
Always round sum error and sum square error toward zero in variance calculations. This prevents variance from becoming negative. Avoiding rounding variance at all might be better but would be far more invasive. Change-Id: Icf24e0e75ff94952fc026ba6a4d26adf8d373f1c

2015-06-03Make vp9 subpixel match vp8Johann
The only difference between the two was that the vp9 function allowed for every step in the bilinear filter (16 steps) while vp8 only allowed for half of those. Since all the call sites in vp9 (<< 1) the input, it only ever used the same steps as vp8. This will allow moving the subpel variance to vpx_dsp with the rest of the variance functions.

2013-06-20SSE2/SSSE3 optimizations and unit test for sub_pixel_avg_variance().Ronald S. Bultje
Encoding of bus @ 1500kbps (first 50 frames) goes from 3min57 to 3min35, i.e. approximately a 10.5% speedup. Note that the SIMD versions which use a bilinear filter (x_offset & 7 || y_offset & 7) aren't perfectly interleaved, and can probably be improved further in the future. I've marked this with a few TODOs/FIXMEs in the code. Change-Id: I5c9e900c0f0d32e431a50fecae213b510b2549f9
2013-06-20Implement sse2 and ssse3 versions for all sub_pixel_variance sizes.Ronald S. Bultje
Overall speedup around 5% (bus @ 1500kbps first 50 frames 4min10 -> 3min58).
