      Fix data type for eobs[] array in SB 4x4 IDCT code. · dd9d4f9e
      Ronald S. Bultje authored
      This fixes encoder/decoder mismatches with the superblock experiment
      turned on whenever a superblock is encoded using the 4x4 transform.

      Remove 'thismb' data pointer when superblock experiment is on. · 73987d14
      Ronald S. Bultje authored
      This should prevent inconsistent results between identical encodes with
      the superblock experiment turned on.

      New b-intra mode where direction is contextual · d01357bb
      Deb Mukherjee authored
      Preliminary patch on a new 4x4 intra mode B_CONTEXT_PRED where the
      dominant direction from the context is used to encode. Various decoder
      changes are needed to support decoding of B_CONTEXT_PRED in conjunction
      with hybrid transforms since the scan order and tokenization depends on
      the actual direction of prediction obtained from the context. Currently
      the traditional directional modes are used in conjunction with the
      B_CONTEXT_PRED, which also seems to provide the best results.
      
      The gains are small - in the 0.1% range.

      Implement tx_select for superblock encoding. · 1d4fbeb3
      Ronald S. Bultje authored
      Also split superblock handling code out of decode_macroblock() into
      a new function decode_superblock(), for easier readability.
      
      Derf +0.05%, HD +0.2%, STDHD +0.1%. We can likely get further gains
      by allowing to select mb_skip_coeff for a subset of the complete SB
      or something along those lines, because although this change allows
      coding smaller transforms for bigger predictors, it increases the
      overhead of coding EOBs to skip the parts where the residual is
      near-zero, and thus the overall gain is not as high as we'd expect.

      Optimize 16x16 dequant and idct · 6c17c9fa
      Yunqing Wang authored
      As suggested by Yaowu, simplified 16x16 dequant and idct. In decoder,
      after detoken step, we know the number of non-zero dct coefficients
      (eobs) in a macroblock. Idct calculation can be skipped or simplified
      based on eobs, which improves the decoder performance.

      Rough merge of master into experimental · 7b8dfcb5
      John Koleszar authored
      Creates a merge between the master and experimental branches. Fixes a
      number of conflicts in the build system to allow *either* VP8 or VP9
      to be built. Specifically either:
      
        $ configure --disable-vp9 $ configure --disable-vp8
        --disable-unit-tests
      
      VP9 still exports its symbols and files as VP8, so that will be
      resolved in the next commit.
      
      Unit tests are broken in VP9, but this isn't a new issue. They are
      fixed upstream on origin/experimental as of this writing, but rebasing
      this merge proved difficult, so will tackle that in a second merge
      commit.

      Fix variance (signed integer) overflow · 98473443
      James Zern authored
      In the variance calculations the difference is summed and later squared.
      When the sum exceeds sqrt(2^31) the value is treated as a negative when
      it is shifted which gives incorrect results.
      
      To fix this we force the multiplication to be unsigned.
      
      The alternative fix is to shift sum down by 4 before multiplying.
      However that will reduce precision.
      
      For 16x16 blocks the maximum sum is 65280 and sqrt(2^31) is 46340 (and
      change).
      
      This change is based on:
