      Support ext-skip for both low delay and high delay · 104d62e1
      Zoe Liu authored
      For both low delay and high delay scenarios, the reference pair in
      skip mode are specified as the closest fwd ref, together with the
      closest bwd ref if there is any bwd ref, otherwise with the two
      closest fwd refs.
      
      Skip mode by default uses COMPOUND_AVERAGE. When all the reference
      frames are on the same side, temporal-distance weighted compound is
      considered, and a compound index is signaled to indicate whether
      distance-weighted compound or compound-average is usd.
      
      Whether to use distance-weighted compound for skip mode is still
      under experimenting, hence a flag is temporarily added:
      SKIP_MODE_WITH_JNT_COMP.
      
      Following experimental results are obtained over 30 frames, using the
      setup of --disable-ext-partition --disable-ext-partition-types
      --disable-txmg --enable-jnt-comp --enable-mfmv --enable-ext-skip:
      
      (1) High Latency:
      For Google test sets (lowres/midres), the BDRate coding gain is ~0.2%;
      For AWCY, the coding gain is ~0.1%.
      (2) Low Latency:
      No gain has been observed over Google sets and ~0.1% gain is obtained
      only when temporal-distance weighted prediction is used.

      Add option for optimize_b only in final encode · 251c9dcb
      Sarah Parker authored
      This adds a third option to the optimize_coefficients speed
      feature, which turns off optimize_b in the search but uses
      it in the final encode. This option is not currently being
      used by default.

      Daala TX removes the av1_get_tx_scale() call, which lv_map uses.
      This patch eliminates use of the call when Daala TX is enabled.

      [Clean Up] Remove get_y_mode() · 2eb9b845
      Luc Trudeau authored
      The get_y_mode function, is superfluous, not used consistently, and requires a
      useless block_idx parameter than gets pass around a lot inside the
      codebase for no apparent reason.
      
      The block parameter is misleading, as it could cause people to think all these
      functions actually use this value.

      [CFL] Reorder alpha search for early termination · f2f3156f
      David Michael Barr authored
      This prepares the way for a heuristic to truncate the search.
      
      For a given joint sign value, each plane's alpha is coded
      independently and so the alpha choice is also independent.
      Rather than iterating over all possible pairs, first choose
      for each plane separately and then merge the choices.
      Merge with RD collection and continuously update the bound.
      
      On subset1, then encoder output is identical for most sequences:
        PSNR | PSNR Cb | PSNR Cr | PSNR HVS |   SSIM | MS SSIM | CIEDE 2000
      0.0002 | -0.0058 | -0.0016 |   0.0020 | 0.0025 |  0.0040 |    -0.0022

      round_shift_array: Use SSE4 version everywhere. · 1ac47a7c
      Urvang Joshi authored
      Usage of CPU by round_shift_array goes from 2.01% to 1.04%.
      Overall encoding is slightly faster (~0.05%).
      
      This means some of the intermediate array have to be aligned.
      Also, these functions were moved to common header/source files.
