      Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB. · 4a0f9478
      Dmitry Kovalev authored
      Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing
      them with one constant. Inlining appropriate arguments for functions:
        vp9_cond_prob_diff_update (encoder)
        vp9_diff_update_prob (decoder)

      "_1d" suffix is redundant, so removing it. The same will happen with idct

      Re-design rate-distortion cost tracking buffers · fc19243c
      Jingning Han authored
      This commit re-designs the per transformed block rate-distortion
      costs tracking buffers. It removes redundant buffer usage, makes
      the needed context memory allocation per VP9_COMP instance and
      reuses the same buffer sets inside the rate-distortion optimization
      search loop, thereby avoiding repeatedly requiring memory space.
      
      It reduces speed 0 runtime:
      
      bus at 2000 kbps from 166763ms to 158967ms,
      football at 600 kbps from 246614ms to 234257ms.
      
      Both about 5% speed-up. Local tests suggest about 2% to 5% speed-up
      for speed 1 and 2 settings. This does not change compression
      performance.

      Deprecate the use of PARTITION_INFO from encoder · 03fe08ca
      Jingning Han authored
      Use b_mode_info to store the inter prediction mode of sub8x8 block,
      in replacement of the use of partition_info. Remove redundant buffer
      update for partition_info. For bus_cif at 2000 kbps, this seem to make
      speed 0 about 1% faster.

      All zero coeff skip in IDCT 32x32 · 6594ca88
      Jingning Han authored
      When all coefficients are zeros, skip the corresponding 1-D inverse
      transform. This practice has been used in the SSE2 implementation of
      inverse 32x32 DCT. This commit imports this algorithm into the C code.

      Change to allow less rectangular partion check · e29137df
      Yaowu Xu authored
      For CpuUsed 1 & 2, this commit allow to skip retangular partition check
      when NONE is better than SPLIT. It also changed to allow such logic
      on alt ref frame coding rather than use square partition all them. The
      change has gain compressio about .3% on yt and ythd for both 1&2, It
      helped .6% compression on cif and stdhd for both CpuUsed 1&2.
