      Fix loopfilter bug · 527fc5ca
      John Koleszar authored
      In the rare case were 4x4 interior filtering was called for but no
      8x8 or larger filtering takes place, the previous code was skipping
      the filtering. This patch fixes the issue by including the interior
      mask in the overall mask for the filter application loops.

      Fix loopfilter of leftmost 4x4 edges in SB · 858475a0
      John Koleszar authored
      For cases where there's no transform set in bit 0 (the left edge of
      the SB) but bit 0 of mask_4x4_int is set (the edge 4 pixels from the
      left edge needs filtering), it was incorrectly being skipped before.
      This situation only happens on the leftmost edge of the image, as
      the edge at column 0 is intentionally skipped since there aren't
      pixels to the left to read.

      With the removal of i4X4 and SPLIT_MV modes, the two entries for the
      modes are no longer used. This patch remove the coding of the deltas.

      Reimplementation of loop filter · 043d348a
      John Koleszar authored
      This version of the loop filter supports non-4:2:0 subsampling and
      a fourth plane, as well as changing the filtering order to be more
      friendly to hardware implementations.
      
      The filters are applied first to all vertical edges within the
      64x64 SB, followed by the top horizontal edge and any internal
      horizontal edges. Since filtering is applied on each 4x4 edge
      serially, a dependency is created from filtering one block edge
      to the next. It would be possible to remove this depencnecy by
      building all filtering decisions from the unfiltered
      reconstruction data.

      Remove splitmv. · e6485581
      Ronald S. Bultje authored
      We leave it in rdopt.c as a local define for now - this can be removed
      later. In all other places, we remove it, thereby slightly decreasing
      the size of some arrays in the bitstream.

      Ronald S. Bultje authored
      It remains as a local define in rdopt.c so we can distinguish between
      split and non-split modes in the RD loop, but disappears outside that
      scope in the codec.

      Add an in-loop deringing experiment · 441e2eab
      John Koleszar authored
      Adds a per-frame, strength adjustable, in loop deringing filter. Uses
      the existing vp9_post_proc_down_and_across 5 tap thresholded blur
      code, with a brute force search for the threshold.
      
      Results almost strictly positive on the YT HD set, either having no
      effect or helping PSNR in the range of 1-3% (overall average 0.8%).
      Results more mixed for the CIF set, (-0.5 min, 1.4 max, 0.1 avg).
      This has an almost strictly negative impact to SSIM, so examining a
      different filter or a more balanced search heuristic is in order.
      
      Other test set results pending.
