      Expand skip mode support for all comp frames · 4b847e19
      Zoe Liu authored
      All compound predicted frames now have the choice to either turn on
      or off the use of the skip mode. The current encoder design only
      turns on the use of skip mode when the temporal distances of the two
      reference frames to the current frame are only different by 1.
      This patch also includes a fix on the calculating of the temporal
      distance between the two reference frames to the current frame for
      skip mode.
      Performance wise, this patch does not have noticeable impact as the
      encoder stays with the same choice with the frame-level skip mode

      Speed up by dropping some ref frames in compound search · c683bf9b
      Cheng Chen authored
      Record distortion for each single ref in rd. Rank according to their
      distortions. Then in compound search, drop the combination of ref
      frames of the largest and second largest distortions
      This patch shows neutral performance on google test using lowres
      with 20 frame.
      Local tests show ~5% speed up over baseline.

      daala_tx: Flip the names on od_rotate kernels. · a25c0300
      Nathan E. Egge authored
      The od_rotate kernels were named after the trailing operation (where
       od_rotate_sub() meant that the last operation was a subtraction)
       which became less intuitive after we folded leading addition operation
       into the kernel.
      This patch simply swaps the operations and kernel labels and has no
       change to the actual transform outputs.

      daala_tx: Fold the addition into od_rotate kernel. · a0bec9d1
      Nathan E. Egge authored
      Move the od_add() and od_sub() calls into the od_rotate_sub() and
       od_rotate_add() kernels respectively as suggested by Frank Bossen.
      The number of kernels is reduced by introducing a flag to indicate which
       of the two versions it is (addition or subtraction).
      Additional named flags are added for the slight kernel variations such
       as the averaging or shifting steps which should be correctly inlined by
       the compiler.
      Extra defines are used to add human readable names for the kernel types.
      The named SHIFT parameter is still passed so that the orthonormal and
       asymmetric DST kernels can be combined in a later patch.
      This patch has no change to metrics.

      daala_tx: Unify the asym and ortho DST designs. · b2f82ebd
      Nathan E. Egge authored
      This patch refactors the DST transforms so that the orthonormal and
       asymmetric transforms are now nearly identical (up to multiplicaiton
       constants and an extra set of shifts).
      This means that the DST designs are now embeddable for every level
       and should address hardware concerns about gate area.
      In addition, minor changes were made to improve transform accuracy:
       - all of the transforms now have perfect reconstruction for those
          computations outside the rotations, i.e., all +/- butterfly steps
          are exactly invertible
       - two multiplication constants were reduced below < 1.0 (better for
          SIMD and gives slightly improved accuracy)
       - the averaging bias is removed which saves an extra addition for each
          of the averaging steps
      Additional averaging steps can be removed from the 8-point Type-IV DST
       giving a 68% reduction in MSE for the 32-point DCT, but has not been
       done in the event we use it in place of the 8-point Type-VII DST.

      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:
      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.
