      Enable an activity masking of PVQ · e4c46918
      Yushin Cho authored
      By default, the activity masking is used with PVQ.
      In addition to '--enable-pvq', '--enable-daala-dist' is also
      required by configure to use the activity masking.

      Fix fixed-pt PVQ compand/expand outputs zero gain · 3ebfe2a4
      Yushin Cho authored
      For fixed-point version of PVQ, which is current default,
      added MAXI(1, ) to limit the minimum companded or expanded gain to be one.
      Previously, gain compand/expand function, which is invoked when
      activity masking is enabled, sometimes outputs zero
      then triggered the assert(gain != 0).
      Metric change from floating-pt to fixed-pt PVQ is:
      0.02  0.10      0.08  0.11        0.01    0.02    0.13    -0.30

      Fix encode/decode mismatches for supertx + delta-q · 3aec8d6c
      David Barker authored
      This fixes the following mismatch bugs:
      * At the bitstream level, the decoder would not read the delta_qindex
        information for supertx blocks, but the encoder always sent it,
        leading to the encoder and decoder becoming misaligned.
        The delta_qindex information is still required for supertx blocks,
        so change the decoder to read it.
      * In addition, the quantizer was not properly adjusted for supertx
        blocks at the decoder. We copy the quantizer setup code from
        non-supertx blocks.
      Since this does not change the encoder, it should not have any
      quality impact.

      Bugfix: Fix an assert being triggered because of palette. · 451e0f22

      David Barker authored
      Allow the above combination of experiments to work together
      correctly, fixing an encode/decode mismatch bug when they
      were all enabled.
      This change causes build_masked_compound(_highbd) to only
      ever be called if CONFIG_SUPERTX is off, so wrap these functions
      in an '#if !CONFIG_SUPERTX' block.

      Fix segmentation fault when encoding all keyframes (kf-max-dist=0). · d803cb96
      Urvang Joshi authored
      The issue was that:
      - We call av1_setup_pre_planes() when this is not an intra-only frame,
      - But, we do motion vector search for any frame other than first frame
      Doing both of these only when this is not an intra-only frames makes
      logical sense and fixes the crash too.
      This also avoids doing motion search for intra-only frames in the first
      Verified that there is no change in compression performance for video,
      as well as when forcing all keyframes.
