      pvq: Remove support for disabling nodesync. · 44bb6d06
      Timothy B. Terriberry authored
      This was broken by commit 1238137c.
      
      When calling the generic coder with a max, it truncates the CDF, but
      then tries to encode/decode with the Q15 entropy coder functions
      with built-in adaptation. That causes assertion failures, because the
      total probability isn't 32768.
      
      We could fix it by re-scaling the CDF, and then doing adaptation
      assuming there was no max, but that requires several special-case
      code paths.
      
      Instead, since non-robust streams were the only thing that still
      required calling the generic coder with a max, and since the gain
      from them is very small (and they require doing more DSP just to be
      able to parse the stream), we simply remove the option and force
      the use of robust streams all the time.
      
      With robust streams enabled, encoder output should not change, and
      all streams should remain decodable without decoder changes.
      
      Thanks to Nathan Egge for reporting the problem.

      Use block_idx rather than block_raster_idx · 752ccce7
      Angie Chiang authored
      1) block_raster_idx is actually raster order only when tx_size
      is TX_4x8.
      It's very specific, so we should put it near to the place it's
      actually used.
      
      2) Sync the meaning of block_idx on encoder/decoder sides

      PVQ uses backward updated context in a tile · c49ef3a1
      Yushin Cho authored
      In the beginning of encoding and bitstream packing,
      the frame context in common of codec is copied to the frame context
      in each tile.
      Initial prob and context is based on flat probability and
      does not come from table at the moment.

      Account for elided extrabits during rate cost calculation. · da3d94fe
      Alex Converse authored
      Fixes some rd-debug mismatches coding cat6 tokens with tx size < 32x32.
      For these tokens the high extrabits are elided during tokenization and
      detokenization, but the rd cost was computed with the old tables from
      VP9 where these high extrabits are always coded.

      Add chroma 2x2 block experiment · 31b6a4f9
      Jingning Han authored
      Support the use of 2x2 prediction and transform block size for
      chroma components. This experiment builds on top of cb4x4. It
      brings back the loss in performance gains due to 4x4 chroma
      component constrain. The coding gains for lowres are up from 1.5%
      to 2.5%.

      Remove PVQ_CHROMA_RD codes · 5c207296
      Yushin Cho authored
      Which was a workaround to balance the quality between
      luma and chroma when PVQ is enabled, by
      1) skipping PVQ DC RDO for chroma and
      2) using smaller lambda value (x0.5) for intra prediction of chroma,
      intended to spend more bits and thus improve quality for chroma.
