2016-08-23Remove halfpix specializationJohann
This function only exists as a shortcut to subpixel variance with predefined offsets. xoffset = 4 for horizontal, yoffset = 4 for vertical and both for "hv" Removing this allows the existing optimizations for the variance functions to be called. Instead of having only sse2 optimizations, this gives sse2, ssse3, msa and neon. BUG=webm:1273 Change-Id: Ieb407b423b91b87d33c4263c6a1ad5e673b0efd6

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
