      WIP: 4x4 idct/recon merge · ba48a111
      Scott LaVarnway authored
      This patch eliminates the intermediate diff buffer usage by
      combining the short idct and the add residual into one function.
      The encoder can use the same code as well.

      With the scatter scan experiment enabled the results were

      Framework changes in nzc to allow more flexibility · fe9b5143
      Deb Mukherjee authored
      The patch adds the flexibility to use standard EOB based coding
      on smaller block sizes and nzc based coding on larger blocksizes.
      The tx-sizes that use nzc based coding and those that use EOB based
      coding are controlled by a function get_nzc_used().
      By default, this function uses nzc based coding for 16x16 and 32x32
      transform blocks, which seem to bridge the performance gap
      substantially.
      
      All sets are now lower by 0.5% to 0.7%, as opposed to ~1.8% before.

      Redo banding for all transforms. · 3120dbdd
      Ronald S. Bultje authored
      Now that the first AC coefficient in both directions use the same DC
      as their context, there no longer is a purpose in letting both have
      their own band. Merging these two bands allows us to split bands for
      some of the very high-frequency AC bands.
      
      In addition, I'm redoing the banding for the 1D-ADST col/row scans. I
      don't think the old banding made any sense at all (it merged the last
      coefficient of the first row/col in the same band as the first two of
      the second row/col), which was clearly an oversight from the band being
      applied in scan-order (rather than in their actual position). Now,
      coefficients at the same position will be in the same band, regardless
      what scan order is used. I think this makes most sense for the purpose
      of banding, which is basically "predict energy for this coefficient
      depending on the energy of context coefficients" (i.e. pt).
      
      After full re-training, together with previous patch, derf gains about
      1.2-1.3%, and hd/stdhd gain about 0.9-1.0%.

      Use above/left (instead of previous in scan-order) as token context. · 790fb132
      Ronald S. Bultje authored
      Pearson correlation for above or left is significantly higher than for
      previous-in-scan-order (absolute values depend on position in scan, but
      in general, we gain about 0.1-0.2 by using either above or left; using
      both basically just makes this even better). For eob branch skipping,
      we continue to use the previous token in scan order.
      
      This helps about 0.9% on derf after re-training on a limited data set.
      Full re-training and results on larger-resolution clips are pending.
      
      Note that this commit breaks trellis, so we can probably get further
      gains out of it by fixing trellis at some later point.

      Coding con-zero count rather than EOB for coeffs · eb6ef241
      Deb Mukherjee authored
      This patch revamps the entropy coding of coefficients to code first
      a non-zero count per coded block and correspondingly remove the EOB

      STATUS:
      Main encode/decode code achieving encode/decode sync - done.
      Forward and backward probability updates to the nzcs - done.
      Rd costing updates for nzcs - done.
      Note: The dynamic progrmaming apporach used in trellis quantization
      is not exactly compatible with nzcs. A suboptimal approach has been
      used instead where branch costs are updated to account for changes
      in the nzcs.

      Make superblocks independent of macroblock code and data. · 111ca421
      Ronald S. Bultje authored
      Split macroblock and superblock tokenization and detokenization
      functions and coefficient-related data structs so that the bitstream
      layout and related code of superblock coefficients looks less like it's
      a hack to fit macroblocks in superblocks.
      
      In addition, unify chroma transform size selection from luma transform
      size (i.e. always use the same size, as long as it fits the predictor);
      in practice, this means 32x32 and 64x64 superblocks using the 16x16 luma
      transform will now use the 16x16 (instead of the 8x8) chroma transform,
      and 64x64 superblocks using the 32x32 luma transform will now use the
      32x32 (instead of the 16x16) chroma transform.
      
      Lastly, add a trellis optimize function for 32x32 transform blocks.
      
      HD gains about 0.3%, STDHD about 0.15% and derf about 0.1%. There's
      a few negative points here and there that I might want to analyze
      a little closer.
