      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.

      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:
      16982342 Missed some variance casts
