      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%.

      Adds speed 8 to vp9 as reference · f872a98b
      Deb Mukherjee authored
      Adds a speed 8 to VP9 where only the nearestmv (0 mv) is searched.
      This seems to be about the same speed as vp8 speed 5.
      
      Adds a new speed feature to disable inter modes based on a mask for
      each blocksize.
      
      Adds code for having lower complexity motion search methods
      in nonrd pick mode function, even though speed 7 still uses DIAMOND
      search for now.
      
      Also uses HEX search for speed 6 rather than FAST_HEX which improves
      psnr by 0.56% without any noticeable speed drop (tested on gipsmotion).

      Fix potential invalid partition size use · bf5e9221
      Jingning Han authored
      For blocks at frame boundary, the selected block size sometimes needs
      to be smaller than that was first given. This commit forces such block
      size change only between square blocks, so as to avoid the potential
      use case containing 32x16 + 16x8 + 16x8, for 1080p sequences.
      
      Local test suggested no visible coding speed difference. Borg test
      reveals no difference in terms of compression performance.
