      Limit mv range to be based on partition size · 13930cf5
      Yaowu Xu authored
      Previous change c4048dbd limits the mv search range assuming max block
      size of 64x64, this commit change the search range using actual block
      size instead.

      used invalid display size equal to the previous frame size (not to the

      Fix bug in convolution functions (filter selection) · 3f108313
      Adrian Grange authored
      (In response to Issue 604:
       https://code.google.com/p/webm/issues/detail?id=604)
      
      There were bugs in the convolution code for two cases:
      
      1. Where the filter table was assumed to be aligned to a
         256 byte boundary. The offset of the pixel in the
         source buffer was computed incorrectly.
      
      2. Where no such alignment assumption was made. An
         incorrect address for the filter table base was used.
      
      To fix both problems, I now assume that the filter table is
      256-byte aligned and modify the pixel offset calculation to
      match.
      
      A later patch should remove the restriction that the filter
      table is aligned to a 256-byte boundary.
      
      There was also a bug in the ConvolveTest unit test
      (convolve_test.cc).
      
      (Bug & initial fix suggestion submitted by Tero Rintaluoma
      and Sami Pietilä).

      Refactor rd_pick_partition for parameter control · 01a37177
      Jingning Han authored
      This commit changes the partition search order of superblocks from
      {SPLIT, NONE, HORZ, VERT} to {NONE, SPLIT, HORZ, VERT} for
      consistency with that of sub8x8 partition search. It enable the use
      of early termination in partition search for all block sizes.
      
      For ped_area_1080p 50 frames coded at 4000 kbps, it makes the runtime
      goes down from 844305ms -> 818003ms (3% speed-up) at speed 0.
      
      This will further move towards making the in-search partition types
      configurable, hence unifying various speed-up approaches.
      
      Some speed 1 and 2 features are turned off during the refactoring
      process, including:
      disable_split_var_thresh
      using_small_partition_info
      
      Stricter constraints are applied to use_square_partition_only for
      right/bottom boundary blocks. Will bring back/refine these features
      subsequently. At this point, it makes derf set at speed 1 about
      0.45% higher in compression performance, and 9% down in run-time.

      Adds a couple of minor fixes, which may be absorbed in Jingning's
      patch. Thanks to Guillaume for pointing these out.
      Also adjusts the thresholds for speed 1 and 2 to 16 and 32
      respectively, to keep quality drops small.

      Make "good" quality 2-pass vpxenc encoding default · 0d8723f8
      Deb Mukherjee authored
      Currently, the best quality mode in VP9 is not very well developed,
      and unnecessarily makes the encode too slow. Hence the command line
      default is changed to "good" quality. Also, the number of passes
      default is changed to 2 passes as well, since 1-pass encoding is
      not very efficient in VP9.
      
      Besides, a number of VP9 defaults are set to the currently
      recommended settings. With these changes, vpxenc
      run with --codec=vp9 --kf-max-dist=9999 --cpu-used=0 should
      work about the same as our borg results.
      Note when the --cpu-used=0 option is dropped there will be a slight
      difference in the output, because of a difference in the cpu-used
      value for the first pass. Specifically, the default when unspecified
      is to use cpu_used=1 for the first pass and cpu_used=0 for the
      second pass. But when specified, both passes will use the cpu-used
      value specified.
      
      Note that this also changes the default for VP8 as being "good"
      but other options stay unchanged.
