      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.

      Fix build when daala_tx and lv_map are both enabled · bca9e9ee
      Monty authored
      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.

      AV1InvTxfm2d: Better test for txfms with approx. · 5dbb9b4c
      Urvang Joshi authored
      Transforms with one of the dimensions being 64 use an approximate 2D DCT
      transform, which makes round trips errors large for randomized input.
      
      So, for such transform sizes, we use a modified test that compares (a)
      reference forward transform + inverse transform to (b) forward transform
      + inverse transform.

      reference_hybrid_2d: Scaling within the function. · ec6acb2b
      Urvang Joshi authored
      Earlier the scaling was done outside the function. But now, we do that
      within the function itself, so that the reference output can be directly
      compared (without scaling) to integerized transform output.

      [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.
