2015-09-09vp8: Small adjustment to cyclic_refresh max_mbs_perframe.Marco
For 3 temporal layers, reduce somewhat the cyclic_refresh_mode_max_mbs_perframe parameter, from 20% to ~14%. Small increase in PSNR/SSIM metrics. Change-Id: Ia216fa5474048f1ef7fe3db88cd60dfef2a1bf8a

2015-08-25Limit new motion vector sizeYaowu Xu
This commit adds clamp of new vectors similar to the logic in RD loop. Such clamp is not necessary from the perspective of VP8 bitstream, but is added to improve ChromeCast mirroring's robustness. Change-Id: I42f6adbc60ffce283b994869364230858632d6fa
2015-08-24vp8: modifcatiion to skin map computation.Marco
For each block in pickinter: use average of four middle pixels (instead of single pixel) to set skin map. This can help a little in reducing false skin detection in some cases. Change-Id: Ic247af75e9c2948b08ab977a39e061adacd8ec97

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.

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

2014-11-20Correctly initialize "ones" value in neon quantizeJohann
By using 0xff for a short it was not setting the high bits. When comparing the output with vtst to find non-zero elements it was skipping vaules which had no low bits set such as -512 / 0xFE00. Using -8191 as the first element of coeff will generate this condition. BUG=883 Change-Id: Ia1e10fb809d1e7866f28c56769fe703e6231a657
2014-11-06Remove asm offset dependenciesJohann
The obj_int_extract code is no longer worth maintaining. It creates significant issues when adapting for different build systems and no longer offers as significant of a performance benefit due to improvements in intrinsics. Source files will remain until the various third-party builds are updated. The neon fast quantizer has been moved to intrinsics. The armv6 version has been removed because so few remaining targets require it. Compilers and processors have improved significantly since the pack_tokens code was written. The assembly is no longer faster than the C code. pack_tokens were the only optimizations for the armv5te targets so the targets will be removed after the test infrastructure has been updated.

2014-11-04Avoid divide-by-zero in vp8 initializationJohann
Check that the numerator is not zero. If it is, guess 30fps. Fixes a clang IOC error in the quantize test. It's very unlikely for this to occur in the wild because the setup in the quantize test is very nonstandard. Change-Id: Icdab7b81d4e168d3423e14db20787f960052e0c3
