      Enable group adaptive max q by default. · 691ec45b
      paulwilkins authored
      Set the GF group adaptive max Q compile flag to 1 by default.
      
      This change has a quite big visual impact in some clips and also
      contributes to tighter rate control.
      
      For short test clips that have consistent content the impact is
      quite small on metrics but for more varied long form clips there is
      a drop in overal psnr but a sharp rise in average psnr caused by
      greater expenditure on some easier sections and tighter rate clipping
      in hard sections.
      
      In chunck'ed encodes some of the effect will already be present due
      to the independent rate control in each chunk but this change takes
      the control down to a smaller scale.

      Revised rd adjustment for variance. · 7e234b92
      paulwilkins authored
      Revised adjustment for rd based on source complexity.
      Two cases:
      
      1) Bias against low variance intra predictors
      when the actual source variance is higher.
      
      2) When the source variance is very low to give a slight
      bias against predictors that might introduce false texture
      or features.
      
      The impact on metrics of this change across the test sets is
      small and mixed.

      Medium to strong psycho-visual improvements in some
      problem clips.

      Experimental rd bias based on source vs recon variance. · 9a1ce7be
      paulwilkins authored
      This experiment biases the rd decision based on the impact
      a mode decision has on the relative spatial complexity of the
      reconstruction vs the source.
      
      The aim is to better retain a semblance of texture even if it
      is slightly misaligned / wrong, rather than use a simple rd
      measure that tends to favor use of a flat predictor if a perfect
      match can't be found.
      
      This improves the appearance of texture and visual quality
      on specific test clips but is hidden under a flag and currently
      off by default pending visual quality testing on a wider Yt set.

      Restore first ref frame pointer to the correct value · 12d946df
      Adrian Grange authored
      The joint_motion_search function alternates prediction
      between two reference frames. In order to reuse existing
      code, a pointer to the appropriate reference frame is
      written into xd->plane[0].pre[0], that the motion
      estimation code assumes points to the reference frame.
      
      If this first reference frame was scaled then the
      pointer was incorrectly being reset to point to the
      unscaled reference frame rather than the scaled
      version.

      put spatial svc behind an ABI check · 18613408
      James Zern authored
      this removes the CONFIG_* checks from public headers, but means
      '--enable-experimental --enable-spatial-svc' builds will fail without a
      local change to the ABI in vpx_encoder.h. this should be all right for
      testing this experiment.

      Speed up non-rd mode decision search · 83cbe226
      Jingning Han authored
      This commit makes the encoder to explicitly calculate the SAD
      associated with the LAST_FRAME motion vector and compare it to
      that of the GOLDEN_FRAME given by integral projection motion
      estimation. It skips the expensive sub-pixel motion search over
      GOLDEN_FRAME when the LAST_FRAME can provide fairly good motion
      compensated prediction quality.

      Update to variance partition. · e5210915
      Marco authored
      Use force_split to constrain the partition selection.
      This is used because in the top-down approach to variance partition,
      a block size may be selected even though one of its subblocks may have
      high variance.
      
      In this patch the selection of the 64x64 block size will only
      be allowed if the variance of all the 32x32 subblocks are also below the threshold.
      
      Stil testing, but some visual improvement for areas near slow moving boundary
      can be seen. Metrics for RTC set increase by about ~0.5%.
