2016-07-18prepend ++ instead of post in for loops.Jim Bankoski
Applied the following regex : search for: (for.*\(.*;.*;) ([a-zA-Z_]*)\+\+\) replace with: \1 ++\2) This misses some for loops: ie : for (mb_col = 0; mb_col < oci->mb_cols; mb_col++, mi++) Change-Id: Icf5f6fb93cced0992e0bb71d2241780f7fb1f0a8

2016-07-12deblock filter : moved from vp8 code branchJim Bankoski
The deblocking filters used in vp8 have been moved to vpx_dsp for use by both vp8 and vp9. Change-Id: I5209d76edafc894b550f751fc76d3aa6799b392d
2016-06-27*.asm: normalize label formatJames Zern
add a trailing ':', though it's optional with the tools we support, it's more common to use it to mark a label. this also quiets the orphan-labels warning with nasm/yasm. BUG=b/29583530 Change-Id: I46e95255e12026dd542d9838e2dd3fbddf7b56e2

Chromium puts all the yasm output in the same directory. Looking at ways to improve this but in the meantime get rid of collisions. Change-Id: I923c5231d14e895ab96521eb89807ede868a0753

2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected. Change-Id: Ie9d06d4028c0de17c63b3a27e6c1b0491cc4ea79
2015-05-06Move shared SAD code to vpx_dspJohann
Create a new component, vpx_dsp, for code that can be shared between codecs. Move the SAD code into the component. This reduces the size of vpxenc/dec by 36k on x86_64 builds. Change-Id: I73f837ddaecac6b350bf757af0cfe19c4ab9327a

2014-06-12Use lrand48 on AndroidJohann
When building x86 assembly use lrand48 instead of the undocumented inlined _rand function. Android now supports rand() https://android-review.googlesource.com/97731 but only for new versions.

2014-05-21Renames x86_64 specific asm filesDeb Mukherjee
Renames all x86_64 specific assembly files to consistently end in _x86_64.asm. This will be useful for build systems to handle these files differently. All new 64-bit specific assembly files should use the new naming convention. Change-Id: I36c89584967c82ffc4088b1b5044ac15d2bb7536

This patch fixed WebRTC Issue 3020: "Uninit error at vp8_mbpost_proc_down_xmm". The first 8 values in d were not initialized, but was accessed. This patch fixed c code as well as mmx and sse2 code. Change-Id: Iaa5b41a4ed3bea971b15fb826ce34b7ab4e36fb1

2013-10-01Merge "Fix linker warnings for bilinear filters"Matthew Heaney
2013-10-01Fix linker warnings for bilinear filtersMatthew Heaney
The declaration of the bilinear filters specified an alignment clause in the implementation file but not in the header. This turned out to be harmless, but it did cause linker warnings to be emitted when building on Windows. The (extern) declaration in the header was changed, to match the declaration in the implementation. Change-Id: I44be89b1572fe9a50fa47a42e4db9128c4897b04

2012-10-08post-proc: deblock filter optimizationYunqing Wang
1. Algorithm modification: Instead of having same filter threshold for a whole frame, now we allow the thresholds to be adjusted for each macroblock. In current implementation, to avoid excessive blur on background as reported in issue480(http://code.google.com/p/webm/issues/detail?id=480), we reduce the thresholds for skipped macroblocks. 2. SSE2 optimization: As started in issue479(http://code.google.com/p/webm/issues/detail?id=479), the filter calculation was adjusted for better performance. The c code was also modified accordingly. This made the deblock filter 2x faster, and the decoder was 1.2x faster overall. Next, the demacroblock filter will be modified similarly. Change-Id: I05e54c3f580ccd427487d085096b3174f2ab7e86
2012-07-27Be consistent with SAD valuesJohann
SAD returns unsigned values. Make all the declarations the same. Remove bestsad initialization and check. It is always set to the result of a SAD call so it will never remain UINT_MAX Use ja instead of jg to test unsigned comparison instead of signed. Update test.

2012-07-02Add 0 offsets handling in SSSE3 sixtap_predict functionsYunqing Wang
This patch fixed issue 458 by calling copy function when both offsets are 0, which guarantees the SSSE3 functions output same result as the c function for all possible offsets. Change-Id: I209aec7a4c6b3362db2646a8887c1038493b6496
2012-06-11Fix pedantic compiler warningsJohn Koleszar
Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

Add PRIVATE macro for adding private_extern directive for yasm to hide global symbols. This is only enabled if -DCHROMIUM is used with YASM. Also fixed a small problem with rtcd_defs.sh to guard TEMPORAL_DENOISING. Change-Id: I9027fce3ebddcf20078293e4b86b396f21da7857
2012-05-22Build unit tests monolithicallyJohn Koleszar
Rework unit tests to have a single executable rather than many, which should avoid pollution of the visual studio project namespace, improve build times, and make it easier to use the gtest test sharding system when we get these going on the continuous build cluster.
