2014-01-10Cleaning up and fixing psnr calculation code.Dmitry Kovalev
Introducing calc_psnr() which calculates psnr between two yv12 buffers. Previously we incorrectly used width/height instead of crop_width/crop_height to calculate number of samples -- fixed. Change-Id: Iecda01980555de55ad347e0276e6641c793fa56c

2014-01-09SSSE3 convolution optimizationlevytamar82
Optimizing all SSSE3 assembly for convolution: 1. vp9_filter_block1d4_h8_sse2 2. vp9_filter_block1d8_h8_sse2 3. vp9_filter_block1d16_h8_sse2 4. vp9_filter_block1d4_v8_sse2 5. vp9_filter_block1d8_v8_sse2 6. vp9_filter_block1d16_v8_sse2 my optimization include: -processing 2x8 elements in one 128 bit register instead of processing 8 elements in one 128 bit register. -removing unecessary loads. This optimization gives between 2.4% user level gain for 480p input and 1.6% user level gain for 720p. This Optimization done only for 64bit. Change-Id: Icb586dc0c938b56699864fcee6c52fd43b36b969

2014-01-08AVX2 Variance Optimizationlevytamar82
Optimizing the variance functions: vp9_variance16x16, vp9_variance32x32, vp9_variance64x64, vp9_variance32x16, vp9_variance64x32, vp9_mse16x16 by migrating to AVX2 some of the functions were optimized by processing 32 elements instead of 16. some of the functions were optimized by processing 2 loop strides of 16 elements in a single 256 bit register This optimization gives between 2.4% - 2.7% user level performance gain and 42% function level gain.

2014-01-07Fix an issue in motion vector prediction stageJingning Han
The previous implementation stops motion vector prediction test when the zero motion vector appears for the second time. This commit fixes it by simply skipping the second time check on zero mv and continuing on to next mv candidate. It slightly improves stdhd in speed 2 by 0.06% on average. Most static sequences are not affected. A few hard ones, like jet, ped, and riverbed were improved by 0.1 - 0.2%. Change-Id: Ia8d4e2ffb7136669e8ad1fb24ea6e8fdd6b9a3c1

2014-01-06Remove avoid_frame_with_high_error from RD loopJingning Han
The feature undergoes prior assumption that the recursive partition size search from 4x4 to 64x64, hence utilizing information from small blocks to determine early termination in large block rate-distortion optimization search. The current codebase is now going from top down. The previous function might go with not properly initialized values, hence removed. Tested on pedestrian_area_1080p at 4000 kbps running under speed 2. No visible difference in runtime observed. Change-Id: I553df415c6191413762db7ae34e8790c71d8118e
