      Add support to recursive transform block coding · cffcfdb8
      Jingning Han authored
      This commit re-designs the bitstream syntax to support recursive
      transform block partition. The initial stage targets the inter
      prediction residuals.

      Use explicit block position in foreach_transformed_block · ebc48efe
      Jingning Han authored
      Add the row and column index to the argument list of unit functions
      called by foreach_transformed_block wrapper. This avoids the
      repeated internal parsing according to the block index.

      Speed up of DST and the search in ext_tx · 3e8cceb3
      Debargha Mukherjee authored
      Adds an early termination to the ext_tx search, and also
      implements the DST transforms more efficiently.
      
      About 4 times faster with the ext-tx experiment.
      
      There is a 0.09% drop in performance on derflr from 1.735% to
      1.648%, but worth it with the speedup achieved.

      Extend the ext_tx experiment to make the UV inter blocks use
      the same transform type as the extended transform type used
      for Y.

      vp10: don't reset contextual skip flag if block has no coefficients. · a5d930e4
      Ronald S. Bultje authored
      The implicitly changed value would be used for contextualizing future
      skip flags of neighbour blocks (bottom/right), which is certainly not
      what was intended. The original code stems from vp8, and was useful
      in cases where coding of the skip flag was disabled. In vp9, the skip
      flag is always coded. The result of this change is that for bitstream
      parsing purposes, decoding of the skip flag becomes independent of
      decoding of block coefficients.
      
      See issue 1014.

      Reduce dqcoeff array size in decoder · cccad1c5
      Jingning Han authored
      The decoding process handles detokenization and reconstruction per
      transform block sequentially. There is no need to offset the dqcoeff
      buffer according to the transform block index. This allows to
      reduce the memory spill and improve cache performance.

      Re-worked header files · b962646f
      Scott LaVarnway authored
      Various header/test files had to be re-worked in order to
      build "Remove cm parameter from vp9_decode_block_tokens()".
      
      This patch reverts the "Remove cm" part and only contains
      the re-worked header files.

      For the test clip used, the decoder performance improved by ~2%.
      This is also an intermediate step towards adding back the
      mode_info streams.
