2014-02-14AVX2 SubPixel Variance Optimizationlevytamar82
Optimizing 2 functions to process 32 elements in parallel instead of 16: 1. vp9_sub_pixel_variance64x64 2. vp9_sub_pixel_variance32x32 both of those function were calling vp9_sub_pixel_variance16xh_ssse3 instead of calling that function, it calls vp9_sub_pixel_variance32xh_avx2 that is written in avx2 and process 32 elements in parallel. This Optimization gave 70% function level gain and 2% user level gain Change-Id: I4f5cb386b346ff6c878a094e1c3b37e418e50bde

2014-01-21Adds a non-normative resize library to vp9 encoderDeb Mukherjee
Adds an arbitrary-size resize library for use in scaling of input frames in a non-normative manner in the vp9 encoder. The method used is as follows: Downsampling - Uses a 8 tap filter for factor of 2 decimation upto a size just higher than the desired size. Then interpolates pixels at a precision of 1/32 pel using a set of 8-tap filters. Upsampling - Interpolates pixels at a precision of 1/32 pel using a set of 8-tap filters. There is no assembly optimization yet. Change-Id: Ib5b81e174fc139da322bb97c8214d52289d60d8a

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.

2013-10-16Implement variance-based adaptive quantizationGuillaume Martres
This should be similar to what x264 does with --aq-mode 1. It works well with clips like parkjoy and touhou (http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv). At low bitrates, the segmentation signaling overhead may negate the benefits of this feature. (PGW) Default changed to feature OFF to allow provisional merge.

2013-07-01Quantize (64-bit only, for now) SSSE3 SIMD.Ronald S. Bultje
Total encoding time for first 50 frames of bus (speed 0) @ 1500kbps goes 2min34.8 to 2min14.4, i.e. a 10.4% overall speedup. The code is x86-64 only, it needs some minor modifications to be 32bit compatible, because it uses 15 xmm registers, whereas 32bit only has 8. Change-Id: I2df53770c2e850813ffa713e1a91b45b0082b904

2013-06-21Implement SSE2 block_error.Ronald S. Bultje
Change vp9_block_error() to return a 64bit error variable, change all callers to expect a 64bit return value (this will prevent overflows, which we basically don't check for at all right now). Remove duplicate block_error() function, which fixed that through truncation. Remove old (incompatible) mmx/sse2 block_error SIMD versions and replace with a new one that returns a 64bit value. Encoding time of first 50 frames of bus @ 1500kbps goes from 3min29 to 3min23, i.e. a 3% overall speedup. Change-Id: Ib71ac5508b5ee8a80f1753cd85d72df1629abe68
