      Remove dependency of intra mode search skip check on mode order · 33593d1f
      Jingning Han authored
      This commit refactors the vp9_rd_pick_inter_mode_sb function to
      remove the intra mode early termination dependency on the mode
      search order.

      Replace best_mode_index table retrieve with fetching best_mbmode · d96228a0
      Jingning Han authored
      This commit allows the encoder to find current best prediction mode
      state using best_mbmode, instead of fetching from the static mode
      search table via best_mode_index.

      Remove the use of use_lastframe_partitioning at speed 4 · f10d7eed
      Yunqing Wang authored
      The use of use_lastframe_partitioning is totally removed in good-
      quality encoding. Its usage in real-time encoding needs to be
      evaluated to see if it can be removed too.
      
      The Borg tests at speed 4 showed:
      stdhd set: 0.220% psnr gain, 0.166% ssim gain;
      derf set:  0.329% psnr gain, 0.476% ssim gain.
      
      Speed test on selected clips showed 1.54% speedup.(Worst case:
      pedestrian_area_1080p25.y4m, speed loss: 1.5%)

      No longer use use_lastframe_partitioning speed feature · 10921403
      Yunqing Wang authored
      The speedup in rd_pick_partition() function makes it possible
      to drop use_lastframe_partitioning feature. By doing that, we
      achieve good PSNR gain with small speed loss. Also, this makes
      encoding loop less complicated. The code cleanup patch will
      follow.
      
      Borg tests showed:
      1. At speed 2,
         stdhd set: 0.201% PSNR gain, 0.133% SSIM gain;
         derf set:  0.262% PSNR gain, 0.276% SSIM gain.
      2. At speed 3,
         stdhd set: 0.139% PSNR gain, 0.109% SSIM gain;
         derf set:  0.447% PSNR gain, 0.442% SSIM gain.
      
      The average speed loss over selected test clips is within 1%
      with the worst case of 4%.

      Correct the mode decisions in special cases · 1dd9a639
      Yunqing Wang authored
      The rate costs calculated for inter modes are not precise in some
      cases, which causes NEWMV is chosen instead of NEARESTMV, NEARMV,
      and ZEROMV. This patch added checks for these cases, and corrected
      the mode decisions.
      
      Borg tests at speed 3 showed:
      1. stdhd set: 0.102% PSNR gain and 0.088% SSIM gain.
      2. derf set:  0.147% PSNR gain and 0.132% SSIM gain.
      No speed change.

      vp9: correct context buffer resize check · bb4950df
      James Zern authored
      allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols
      individually, use those to determine whether to realloc rather than
      stride and stride * rows. this fixes a crash with some fuzzed files for
      invalid accesses into last_frame_seg_map and above_context.

      Enable adaptive motion search for ARF coding · d435148f
      Jingning Han authored
      This commit turns on adaptive motion search for ARF coding, in
      addition to other normal inter frame coding. It improves the
      average compression efficiency:
      
      stdhd 0.1%
      derf  0.04%
      
      For the test sequences, the speed 3 runtime is reduced:
      
      pedestrian 1080p 2000 kbps, 149932 ms -> 144580 ms, (3.3% speed-up)

      JackyChen authored
      When the first try of denoising turns out to be too much,
      we will use a softer filter by adopting an adjustment to
      make the result closer to original pixel (as in VP8 denoiser).
      The old code made the adjustment in the wrong direction.
