2014-10-10Add adaptation option for VBR.Paul Wilkins
Allow min and maxQ to creep when the undershoot or overshoot exceeds thresholds controlled by the command line under_shoot_pct and over_shoot_pct values. Default is 100%,100% which ~disables adaptation. Derf results for example undershoot% / overshoot%:- Head:- Mean abs (%rate error) = 14.4% This check in:- 25%/25% - Mean abs (%rate error) = 6.7% PSNR hit -1% SSIM -0.1% 5% / 5% - Mean abs (%rate error) = 2.2% PSNR hit -3.3% SSIM - 1.1% Most of the remaining error and most of the quality hit is at extreme data rates. The adaptation code still has an exception for material that is in effect static so that we don't over adjust and over spend on YT slide show type content.

2014-10-08Subpel search cleanups and enhancementsDeb Mukherjee
- Some fixes to surface fit. - Returns variance function as cost rather than sad in the pattern search and diamond search functions. Only vp9_pattern_search_sad function used in bigdia search uses sad as integer 1-away costs. - Deploys SUBPEL_TREE_PRUNED_MORE for speed 4+. Results: derf [Speed 3]: About +0.036% in coding efficiency without any discernible speed loss. derf [Speed 4]: About 2-3% faster at -0.199% loss in coding efficiency. derf [Speed 5]: About 3-4% faster at -0.149% loss in coding efficiency.

2014-10-08Merge "Allow mode search breakout at very low prediction errors"Yunqing Wang
2014-10-08Allow mode search breakout at very low prediction errorsYunqing Wang
In model_rd_for_sb function, the spatial domain SSE and variance are checked to see if transform coefficients are quantized to 0. Besides that, this patch adds another set of thresholds that are much more strict. These thresholds are used to conduct a partition block level check to measure if all its TX blocks are skippable for YUV planes. If it is true, x->skip is set for this partition block, and thus its mode search is terminated. This speeds up the encoding at very low prediction error case, such as screen sharing application. This patch covers what rd_encode_breakout_test() does, so that function is removed. Borg test at speed 3 shows: For stdhd set, psnr: +0.008%, ssim: +0.014%; For derf set, psnr: +0.018%, ssim: +0.025%. No noticeable speed change. Change-Id: I4e5f15cf10016a282a68e35175ff854b28195944

2014-10-08Fix src frame buffer copy and extendYaowu Xu
For input source with size that is not multiple of 8, the size is rounded to 8 and saved in width or height, the original source sizes are saved in crop_width and crop_height. This commit corrects the computation of bottom and right extension amounts to use the orignal sizes, hence crop_width and crop_height. In addition, this commit also adds the missed initialization for uv_crop_width and uv_crop_height. This addresses issue #834 Change-Id: I084543ca7645a4964b88f7cf8ff668f517d3a39b

2014-10-07experimental : partition using 1/8 x 1/8 imageJim Bankoski
The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.

2014-10-06Add SSE2 code and unit test for VP9 denoiser.JackyChen
This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are only 16x16 blocks in denoiser, while in VP9, there are 13 different block sizes. By adding this SSE2 code, the improvement of encoder speed is around 20%(using C code vs using SSE2 code), vary for different clips. The unit test for VP9 denoiser is to confirm that the SSE2 code is bit-exact with the C code. The unit test covers all block size. Change-Id: Ic8d8ac26db4ea40a5f146b5678a065af07eaaa3d

2014-10-06Improve two pass VBR accuracy.Paul Wilkins
Adjustments to the GF interval choice and minimum boost. Adjustment to the calculation of 2 pass worst q. Compared to 09/29 head there is metrics hit on derf of (-0.123%,-0.191%) Compared to the September 29 head and a baseline on September 18 baseline the accuracy of the VBR rate control measured on the derf set is as follows:- Mean error % / Mean abs(error %) Sept 18 baseline (-7.0% / 14.76%) Sept 29 head (-15.7%, 19.8%) This check in (-1.5% / 14.4%) The mean undershoot is reduced slightly but the worst case overshoot on e.g. harbour/highway is increased. This will be addressed in a later patch. Change-Id: Iffd9b0ab7432a131c98fbaaa82d1e5b40be72b58
