      cb4x4: Move sub-4X4 TX sizes behind CONFIG_CHROMA_2X2. · fe67ed6a
      Timothy B. Terriberry authored
      cb4x4 itself should not require these sizes.
      
      This simplifies compatibility with other experiments, since we can
      first make them work with cb4x4 (which is now on by default), and
      then worry about chroma_2x2 (which is not) in separate steps.
      
      Encoder and decoder output should remain unchanged.

      new_tokenset: Add missing blockzero_probs for cb4x4. · 90ed98f9
      Timothy B. Terriberry authored
      cb4x4 adds a new TX_2X2 to the TX_SIZES enum, which offsets the
      indexing of blockzero_probs. Add a set of default probabilities for
      this case (simply copied from the TX_4X4 probabilities).
      
      These will only be used if chroma_2x2 is enabled (though moving the
      other probabilities back to their correct offset will affect all
      other sizes).
      
      This is an encoder-only change.

      This is the second patch.
      * Add delta loop filter level at super block level.
      * Add symbol coding for delta lf syntax
      * Allow delta lf to work with segments

      ec_smallmul: Convert CDFs to iCDFs. · f6c807c5
      Timothy B. Terriberry authored
      Hoists the iCDF conversion outside of the daala code.
      We directly store 32768 - cdf[i] in each cdf, to avoid having to
      convert the whole array every time a symbol is coded.
      
      This works with ec_multisymbol, new_tokenset, and ec_adapt.
      
      Compared to Change-Id Idbbd3743e9189146cb519d5b984bdabd69e3f4c0,
      this improves decoder runtimes by 1.15% at QP=55 and 2.64% at
      QP=20.
      
      The overall slowdown of ec_smallmul is now 0.12% at QP=55 and
      0.44% at QP=20.
      
      Encoder output should not change, and all streams should remain
      decodable without decoder changes.
