      Recursive partition syntax coding · 90a91cc6
      Jingning Han authored
      Enable recursive partition information coding from SB64X64 down to
      MB16X16. The bit-stream syntax is now supporting rectangular block
      sizes. It starts from SB64X64 and recursively describes the partition
      type of the current block. If the partition type is PARTITION_NONE,
      the block is coded as a single unit; if it is PARTITION_HORZ or
      PARTITION_VERT, the block is segmented into two independently coded
      rectangular units, with no further partition needed; otherwise, the
      block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case,
      each can be potentially further partitioned.
      
      Forward adaptive probability modeling is used for the partition
      information coding, conditioned on the current block size.

      Remove the mb_no_coeff_skip flag · e3cfe4e8
      John Koleszar authored
      This flag was added to VP8 to allow a mode where MB-level skipping
      was not allowed, saving a bit per mb. It was never used in practice,
      and hasn't been tested in VP9, so remove it.

      Moving tx_type == DCT_DCT checks inside iht_add functions. · 3609856a

      tx_type == DCT_DCT check is an implementation detail of iht_add. Also
      adding dequant_add_y function with explicit DCT_DCT check inside.

      Enable inter predictor for rectangular block size · 3ba9dd41
      Jingning Han authored
      Combine superblock inter predictors into a unified function that
      allows configurable block width and height. The inter predictions
      of block sizes smaller than 16x16 are handled differently. To be
      continued on merging them later.

      Make dequant/idct block size independent · bbd0063b
      Jingning Han authored
      The unified dequantization, inverse transform, and adding functions
      support rectangular block sizes. Also separate the operations on
      luma and chroma components, in the consideration of the txfm_size
      for uv components in rectangular block sizes.

      Ronald S. Bultje authored
      Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code
      gives identical encoder results before and after. There are a few
      macros for rectangular block sizes under the sbsegment experiment; this
      experiment is not yet functional and should not yet be used.
