2019-04-11Fix static analysis warningskyslov
With switching to clang-7.0.1 we got new warnings. With this change the warnings are back to 0 for all configurations (excluding warnings in third_party) BUG=webm:1616 Change-Id: I25ceb592c425394e8f14d333fb5680144f892213

2016-05-25Refactor probability savings search.Alex Converse
- Avoid excessive copying - Don't both searching if no update can possibly offer savings - Simplify the interface - Remove the confusing vp9_cost_upd256 macro Change-Id: Id9d9676a361fd1203b27e930cd29c23b2813ce59

2016-01-15Tie the bit cost scale to a define.Alex Converse
This is a pure-refactor in preparation to potentially raise the bit-cost resolution. Verified at good speed 0 and rt speed -6. Change-Id: I5347e6e8c28a9ad9dd0aae1d76a3d0f3c2335bb9

2015-05-15vp9_subexp.h: add a missing prototypeJames Zern
+ include the .h in the .c silences missing prototype warnings Change-Id: Ia87366dccb4bf4e9f2ffa5d3ab51ac6ca5488c91
2015-04-28vpx_mem: remove vpx_memcpyJames Zern
vestigial. replace instances with memcpy() which they already were being defined to. Change-Id: Icfd1b0bc5d95b70efab91b9ae777ace1e81d2d7c
2014-12-03Rework coeff probability model update for rtc codingJingning Han
This commit reworks the ONE_LOOP_REDUCED coefficient probability model update process. It allows model update for every coefficient across the spectrum at a coarser resolution, instead of performing precise update only for certain subset of probability models. The overall runtime remains nearly same (<1% change) for speed -6. The compression performance is improved by 7.5% in PSNR for speed -5 and 4.57% for speed -6, respectively.

2013-10-11Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB.Dmitry Kovalev
