      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.

      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.

      Add PVQ frame context in common and tiles. · b188ea14
      Yushin Cho authored
      In preparation for enabling backward updates of contexts for PVQ.
      1. Default prob setting for PVQ,
      which is based on flat probabilities at the moment.
      2. At the end of encoding a frame, average probablities and expected values
      of PVQ are copied to the frame context.

      EC_ADAPT: Perform backwards updates directly on CDFs. · 028b57f5
      Thomas Davies authored
      The initial CDF for each frame is stored in
      the frame context. CDFs for actual coding are
      stored in the tile structures, and these are
      what get adapted. The initial CDF is replaced
      by an average CDF derived from these tile CDFs.
      This is carried forward to future frames when
      backward adaptation is on.
      
      CDFs are no longer set from the 8 bit probabilities
      in backwards adaptation.
      
      For now, 8 bit probabilities are maintained for
      use in the encoder and for symbols which do not
      have a CDF.
