      Fix a bug in vp9_rd_pick_inter_mode_sb · 68d79146
      Jingning Han authored
      This commit fixes a bug related to skipping intra mode checking, by
      using a separate variable to store the best prediction error from
      inter mode. It avoids unintentionally overwriting intra mode
      rate-distortion cost, and hence affecting other speed features.

      Remove redundant ref frame pointer assignment · 9a9e2aef
      Jingning Han authored
      Assigning selected reference frame pointer is done in the
      encode_superblock function. No need to do this at the end of
      rate-distortion optimization search.

      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
      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)
      bus CIF 1000 kbps, 8050 ms -> 7895 ms, (1.9%)
      highway CIF 100 bkps, 45033 ms -> 44078 ms, (2.2%)
