      Yaowu Xu authored
      1. remove prediction mode conversion
      2. unified bmode, same for key and non-key frame
      3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer
      coded ever. It is determined by ref_frame and block partition

      Enable recursive partition down to 4x4 · 1f26840f
      Jingning Han authored
      This commit allows the rate-distortion optimization recursion
      at encoder to go down to 4x4 block size. It deprecates the use
      of I4X4_PRED and SPLITMV syntax elements from bit-stream
      writing/reading. Will remove the unused probability models in
      the next patch.
      
      The partition type search and bit-stream are now capable of
      supporting the rectangular partition of 8x8 block, i.e., 8x4
      and 4x8. Need to revise the rate-distortion parts to get these
      two partition tested in the rd loop.

      Contextual entropy coding of partition syntax · ff2b8aa2
      Jingning Han authored
      This commit enables selecting probability models for recursive block
      partition information syntax, depending on its above/left partition
      information, as well as the current block size. These conditional
      probability models are reasonably stationary and consistent across
      frames, hence the backward adaptive approach is used to maintain and
      update the contextual models.
      
      It achieves coding performance gains (on top of enabling rectangular
      block sizes):
      derf:   0.242%
      yt:     0.391%

      This patch revamps the entropy coding of coefficients to code first
      a non-zero count per coded block and correspondingly remove the EOB

      Main encode/decode code achieving encode/decode sync - done.
      Forward and backward probability updates to the 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

      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.

      the lossless experiment is not enabled.
      3. Renamed function pointers for transforms to be consistent, using
      prefix fwd_txm and inv_txm for forward and inverse respectively
      
      To encode in lossless mode, using "--lossless=1 --min-q=0 --max-q=0"
