      Update to speed 5 non-rd mode partition search. · 478fbc8f
      Marco authored
      If the pre-selected partition size (from variance partition) is
      32x32, also apply nonrd partition search for 32x32 and 16x16 size.
      Overall small positive gain in metrics, average ~1%.
      Some visual improvement, for lower resolutions.

      Alter partition search at image edge. · 99f8bd72
      paulwilkins authored
      Added code to reduce the minimum partition size searched
      for super blocks at or straddling the edge of the image.
      If the first pass has detected formatting bars the "active" edge
      may not be the real edge.

      Fixes for key frame coding at speed 5. · fb2a89b1
      Marco authored
      Keep the same transform cutoff and partition selection
      for speed 5 as in speeds >=6 (non-rd speed settings).
      Existing setting for key frame at speed 5 allowed transform size
      up to 32x32 on key frames, and did not allow for 4x4 block partition size.
      This created more visual artifacts on first few frames.
      avgPSNR/overallPSNR/SSIM gains of 0.2/0.7/0.8 for rtc_derf(low-res) set,
      and 0/0.7/1.1 gains for rtc set.

      Reduce max_partition_size for low resolutions at speed 5. · debe4e92
      Marco authored
      For speed 5 real-time mode, the selection of the partition size for
      superblocks on the segment (aq-mode=3) uses the non-rd recursive
      pick partition search, and can sometimes select 64x64.
      For low resolutions, visually better to limit this to 32x32.

      this macro was used inconsistently and only differs in behavior from
      DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
      is used with calls to assembly, while generic c-code doesn't rely on it,
      so in a c-only build without an alignment attribute the code will
      function as expected.

      Image size restriction to rd auto partition search. · 4a7dcf8e
      paulwilkins authored
      Impose a limit on the rd auto partition search based on
      the image format. Smaller formats require that the search
      includes includes a smaller minimum block size.
      This change is intended to mitigate the visual impact of
      ringing in some problem clips, for smaller image formats.

      For color sampling format other than 420, valid partion size in Y may
      not work for UV plane. This commit adds validation of UV partition
      size before select the partition choice.
      This fixes a crash for real time encoding of 422 input.

      Force_split on 16x16 blocks in variance partition. · eb8c6675
      Marco authored
      Force split on 16x16 block (to 8x8) based on the minmax over the 8x8 sub-blocks.
      Also increase variance threshold for 32x32, and add exit condiiton in choose_partition
      (with very safe threshold) based on sad used to select reference frame.
      Some visual improvement near moving boundaries.
      Average gain in psnr/ssim: ~0.6%, some clips go up ~1 or 2%.
      Encoding time increase (due to more 8x8 blocks) from ~1-4%, depending on clip.
