      Urvang Joshi authored
      This experiment extends ALT_INTRA by adding two new modes:
      smooth horizontal and smooth vertical.

      The coding gain from this experiment can be mostly obtained
      from ec-adapt.

      configure: Disable ext_delta_q if delta_q disabled · ffbe8533
      Fergus Simpson authored
      Builds will fail if configured with delta_q disabled and ext_delta_q not
      also disabled, since ext_delta_q is soft enabled. This patch fixes this
      by making the configure script disable ext_delta_q if delta_q is not
      enabled.

      Enable dual filter by default · b14c1799
      Jingning Han authored
      Temporarily disable the use of 10/12-tap filter.
      
      The filter type coding dependency on motion vector coding has been
      removed previously. Every inter block now has to send filter type
      regardless of the motion vector position.
      
      Enable the dual filter scheme.

      [CFL] Custom block-level DC_PRED · f8164157
      Luc Trudeau authored
      Adds the CfL experiment flag and computes a block-level DC_PRED that is
      required by CfL in order to compute alpha_cb and alpha_cr.
      
      The rate-distorsion impact of computing DC_PRED at the prediction block level
      for chroma planes is rather small

      Drop support for CONFIG_EMULATE_HARDWARE · c6a48a25
      Sebastien Alaiwan authored
      This experiment complexifies DSP function dispatch, without bringing
      any real value (it's non-normative arbitrary behaviour).
      Moreover, it only has an effect on obsolete transforms, the new ones
      don't implement this mechanism.

      Add ec_smallmul experiment. · b1c5760e
      Timothy B. Terriberry authored
      This reduces the multiplier width of daala_ec from 16x15->31 to
      8x15->23, which reduces hardware latency by an estimated 20% (and
      area for this module by an estimated 40%).
      
      These are the smallest logical changes required to achieve this,
      but the approach will be optimized significantly in subsequent
      commits.

      Zoe Liu authored
      This new coding tool is targeted to complete following two tasks:
      (1) Remove the inter mode NEWFROMNEARMV;
      (2) Add new inter coding modes that provide compound prediction but
          using single reference frame - initially NEAREST_NEARMV from
          single reference.
