      Change ref frame coding. · 6ef805eb
      Ronald S. Bultje authored
      Code intra/inter, then comp/single, then the ref frame selection.
      Use contextualization for all steps. Don't code two past frames
      in comp pred mode.

      a few clean-ups · 2b96ffe0
      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

      Reduce bmi buffer length from 16 to 4 · de735929
      Jingning Han authored
      This commit removes the use of bmi_ in the first-pass encoding by
      forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT
      only, as John suggested. This makes the need for bmi buffer only
      up to 4 entries, instead of 16.

      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.

      Context-pred fix to not use top/left on edges · b1921b2f
      Deb Mukherjee authored
      This fix resolves some of the mismatch issues being seen
      recently. While this is the right thing to do when tiling
      is used for this experiment, it is not the underlying cause
      of the the mismatches.
      Something else is causing writing outside of the allowable
      frame area in the encoder leading to this mismatch.

      Note: The dynamic progrmaming apporach used in trellis quantization

      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.
