      aom_dsp/get_prob: make clip_prob branchless · 56310196
      James Zern authored
      + inline the function directly as there was only one consumer
      (get_prob())
      
      this is an attempt to reduce the amount of branches to workaround an amd
      bug. this change is mildly faster or neutral across x86-64, arm.

      Remove redundant loop in ctx_reset · 98bc74ca
      Luc Trudeau authored
      Merges two consecutive loops that iterated over TX_SIZES. There's no
      impact to the bitstream. The 4 used as the termination threshold in the
      second loop is equivalent to TX_SIZES.

      Use default CDF tables when initialising coef probs. · 87aeeb85
      Thomas Davies authored
      When creating the CDF head, do not use 8-bit probabilities
      to make the CDF tables, but load them directly.
      
      CDF tail values are created from the ONE_TOKEN relative
      probability as before.

      improving palette throughput · 33bcd117
      Fangwen Fu authored
      * code the palette color index using 45 wavefront
      * interleave the coeff and palette color index in
        transform block level
      * the above change does not change code efficiency
      
      Details: 
      The 45 wavefront scan allows to compute the ctx of
      the diagonal samples' indices  at the same time. 
      Interleaving palette indices and palette residual
      on a transform block basis means that the entropy
       decoding and further processing of the palette 
      residual is not delayed by the entropy decoding 
      of all the color indices of the palette encoded 
      block.

      Allow disabling the 8-bit (low-bitdepth) operating path. · 98378137
      Sebastien Alaiwan authored
      This allows compiling a codec using the same operating path (the generic
      "high-bitdepth" one), regardless of the profile of the input bitstream.
      For now, keep the 16-bit (generic) pixel operating path disabled by default.

      a carryover with daala_ec.

      Add get_plane_type() helper function. · 005feb6b
      Luc Trudeau authored
      Adds the static inline function get_plane_type to convert a plane number
      to the corresponding PLANE_TYPE.
      
      There's no change to the bitstream, it only encapsulates the logic to
      get the PLANE_TYPE.
