      decision with fixed and variable block sizes.

      Fix bad speed settings interaction. · 2e05341a
      Paul Wilkins authored
      The flag x->skip_recode interacts badly with
      the cpi->sf.use_nonrd_pick_mode and
      cpi->sf.skip_encode_sb speed settings.
      Restricting the use of the skip_decode flag when
      these other speed choices are in use helps quality
      for speeds 3 and 4 by a large amount with only a
      small impact on speed.
      Average improvmentes for 2 pass speed 4:
      Derf +8.8%
      Yt + 10.53%
      Std-Hd +6.95%
      yt-hd + 22.95%

      Enable variable block size test in non-RD mode decision · 60f9ebc3
      Jingning Han authored
      This is an initial attempt to allow variable block size partition
      in non-RD coding flow. It tests 8x8, 16x16 and 32x32 block size per
      64x64 block, all using non-RD mode decision and the associated rate
      distortion costs from modeling, then selects the best block size to
      encode the entire 64x64 block. Such operations are triggered every
      other 3 frames. The blocks of intermediate frames will reuse the
      collocated block's partition type.
      It improves the compression performance by 13.2%. Note that the gains
      are not evenly distributed. For many hard clips, the compression
      performance is improved by 20% to 28%. Local speed test shows that
      it will also increase runtime by 50%, as compared to speed -7. It is
      now enabled in speed -6 setting.

      Preliminary code for variance based paritioning · e39ecfaa
      Deb Mukherjee authored
      Brings back most of Jim's previous patch for choosing
      partitioning based on variance while making it compatible
      with the current state of the code. Also adds a
      nonrd_use_partition() function to recursively encode  for any
      arbitrary sb_type decisions within a 64x64 block; and
      includes some refactoring.
      Currently, when the VAR_BASED_PARTITIONING mode is turned on
      for speed 7, there is a 10+% speed-up observed.
      Experiments/improvements with this new partitioning method
      will be conducted subsequently.

      Use modeled rate distortion costs for non-RD mode · 539c961e
      Jingning Han authored
      This commit replaces SAD cost with modeled rate-distortion cost
      for non-RD mode decision. It translates the prediction residual
      SSE into estimate rate and reconstruction distorion costs, hence
      capturing the quantization setting effect. The compression
      performance of speed -7 for rtc set is improved by 14.79%.
