      Unify the use of encode_b_args/optimize_block_args · ab77828b
      Jingning Han authored
      The struct optimize_block_args is defined same as encode_b_args.
      Remove this redundant definition, and use encode_b_args consistently.

      Make xform_quant operations tx_type independent · e9e2fe8e

      The xform_quant() module is only used by inter modes, hence removing
      the redundant switches therein conditioned on tx_type.

      Skip inverse transform when eob is zero · 0359ad7f
      Jingning Han authored
      When all the transform coefficients were quantized to zero, skip
      the inverse transform operation. For bus_cif at 1000 kbps, the
      runtime goes from 154967ms -> 149842ms, i.e., about 3% speed-up,
      at speed 0.

      clean up bw, bh · 86a9dec7
      Jim Bankoski authored
      many structures use bw and bh and they have different meanings.   This cl attempts
      to start this clean up and remove unneccessary 2 step look up log and then
      shift operations...
      
      also removed partition type multiple operation code in bitstream.c.

      Renaming of segment constants. · 32042af1
      Paul Wilkins authored
      Renamed:
        MAX_MB_SEGMENTS to MAX_SEGMENTS
        MB_SEG_TREE_PROBS to SEG_TREE_PROBS
      
      The minimum unit for segmentation in the segment map
      is now 8x8 so it is misleading to use MB_ as macro-block
      traditionally refers to a 16x16 region.

      Diamond search change to accelerate movement · a1e2d50b
      Deb Mukherjee authored
      Optional change in diamond search to continue in the best move
      direction until that move turns worse.
      
      This is still WIP since the exact way the new method is to be used is
      under investigation. One option is to make it an option in diamond
      search and use it only when motion is large.
      
      Overall slightly positive on derfraw300 +0.02%, stdhdraw +0.13%,
      but works a lot better for high motion sequences (ex. football : +1%).

      Optimize operation flow in sub8x8 rd loop · 409e77f2
      Jingning Han authored
      Stack the rate-distortion statistics in the sub8x8 rd loop. This allows
      the encoder to skip the forward transform, quantization, and coeff cost
      estimation, in the sub8x8 rd optimization search, if the motion
      vector(s) are of integer pixel value, and have been tested in the
      previous prediction filter type rd loops of the same block.
      
      This gives about 2% speed-up for bus_cif at 2000 kpbs, for speed 0.
      Its efficacy depends how frequently the motion search will select an
      integer motion vector.

      Skip buffer update in sub8x8 rd loop · c725502b
      Jingning Han authored
      This commit allows the encoder to skip a few buffer update steps in
      rd_pick_best_mbsegmentation, when early breakout has been triggered
      in the rd_check_segment_txsize. It provides about 1% speed-up for
      bus_cif at 2000 kbps, in the settings of speed 0.

      At speed 2, due to the threshold scheme used, it is possible the rate
      and distortion assigned with INT_MAX value. The patch added checking
      to prevent the INT_MAX value is used in further calculation of RD
      scores. The patch also changed the assertion in rd_use_partition() to
      be mirror similar assertion in rd_pick_partition().
