      Add intra-interp experiment flag · eda3d764
      hui su authored
      intra-interp experiment allows intra prediction to use different
      interpolation filters. It was part of the ext-intra in the nextgenv2
      branch.

      Add domain transform recursive filter · 3981be93
      Debargha Mukherjee authored
      This filter is meant to replace the bilateral filter,
      but is currently added in addition to the bilateral filter
      for testing.

      Deprecated the separate handle on rectangular tx_size in var_tx · fe45b216
      Jingning Han authored
      The recursive transform block partitioning system naturally supports
      the use of rectangular transform block size. Hence there is no need
      to make a separate coding route for the rectangular transform block
      size support there.

      Fix compile with ext-tx · f541932b
      David Barker authored
      The switch to using daala_ec by default broke the compile
      when used with ext-tx, as some code which should have been
      inside #if !CONFIG_EXT_TX was not inside such a block.

      Add ec_multisymbol for common daala_ec and rans code · aca9feba
      Alex Converse authored
      The new ec_multisymbol experiment supersedes the rans experiment and is
      used for multisymbol features that can be backed by either daala_ec or
      rans.
      
      This experiment is automatically enabled by ec_adapt and will try to
      enable daala_ec or ans (in that order).

      Partition the ans experiment into 'ans' and 'rans' · ec6fb649
      Alex Converse authored
      The (new) ans experiment replaces the bool coder with uABS bools. The
      'rans' experiment adds multisymbol coding.
      
      This matches the setup in aom/master.

      Use Daala entropy coder to code bits. · 8043cc40
      Nathan E. Egge authored
      When building with --enable-daala_ec, calls to aom_write() and aom_read()
       use the daala entropy coder to write and read bits.
      When the probability is exactly 0.5 (128), then raw bits are used.
