2015-03-18Adjustments to aq-mode=3.Marco
Factor in segment#2 and skip blocks into the postencode estimated bits, and increase somewhat the aggressiveness of the refresh. PSNR/SSIM Metrics on RTC set go up by ~0.8/0.5%. Change-Id: I5d4e7cb00a3aefb25d18c88b6b24118b72dc5d51

2015-03-17Fix the C version of column vector projectionJingning Han
Make the C and SSE2 versions consistent. Change-Id: I03c405d22a36bd1a97480efb96dc5af230667424
2015-03-17Update to variance partition.Marco
Use force_split to constrain the partition selection. This is used because in the top-down approach to variance partition, a block size may be selected even though one of its subblocks may have high variance. In this patch the selection of the 64x64 block size will only be allowed if the variance of all the 32x32 subblocks are also below the threshold. Stil testing, but some visual improvement for areas near slow moving boundary can be seen. Metrics for RTC set increase by about ~0.5%. Change-Id: Iab3e7b19bf70f534236f7a43fd873895a2bb261d

2015-03-16Refactor column integral projection computationJingning Han
Move the scaling factor outside column projection. This avoids repeated calculation of the same scaling factor. Profiling shows that the percentage of vp9_int_pro_col_sse2 of overall cycles goes from 2.29% down to 1.88%. Change-Id: I5ac4e324ab2d7f33ba2de66dd2a12e04e04dfd66

2015-03-16vp9_pick_inter_mode(): minor optimizationsYaowu Xu
1. remove duplicate initialization to mbmi->interp_filter. 2. move mv clamping into ref_frame loop instead of mode checking loop. 3. move the check if last frame is same as golden frame earlier to avoid initialization of Golden reference related variables.

2015-03-13Fix choose_partitioning threshold setup for speed -5Jingning Han
The compression performance of speed -5 is on average 12.6% better than speed -6. At lower bit-rates, the gains are typically 20% or more. For 2-thread encoding, the speed -5 takes about 1.6x time of speed -6. Change-Id: If7a73464a24d33e8f49b9533b51ec51c8da7fc80

2015-03-13Fix crash with vp9 denoiser on.Marco
Crash occured on very first key frame, because denoiser temporal function was beng entered. Updated denoiser unittest to set cpu_used from first frame, and verified fix fixes the crash. Change-Id: I3be1124b52846fbbe7248d2c3d6136e086c80bc1

2015-03-12Reduce the number of full block SAD callsJingning Han
This commit uses a 6-point 1-step refine motion search in the integral projection based full pixel motion estimation, to replace the current 9-point search. It reduces runtime cost of speed -6 on some noisy clips, e.g., dark720p single thread 33314 b/f, 40.076 dB, 18231 ms -> 33307 b/f, 40.067 dB, 17768 ms The compression performance for rtc set remains unchanged.

2015-03-12vp9_pick_inter_mode(): Use single loop to evaluate inter modesYaowu Xu
This commit changes to use single loop to evaluate all inter modes. There is no impact on compression quality and speed, but allow future experiment with the order of modes evaluated. Change-Id: I71696ce1014cbe127e25e98710d835987f5ecc09
2015-03-12Minorly modify model_rd_for_sb_y functionYunqing Wang
Added a skip_dc check. If skip_dc = 1, we could eliminate calling of vp9_model_rd_from_var_lapndz(). This gave slight PSNR & SSIM gain(<0.1%), and no speed change. Change-Id: If5ca733366148c86b98e196a00cc890f50e9a3e5
