      Enable greedy version of av1_optimize_b(). · 09302f5a
      Urvang Joshi authored
      This has been found to be better than the original version in both ways:
      (1) Better compression: lowres -0.229, midres -0.147
      (2) Faster too in my quick test over 5 different clips with 30
      frames: 2.7% to 10.5% faster.

      2x2 transforms are now hidden behind the CHROMA_2X2 macro,

      Remove --test-16bit-internal option · 0b2e4039
      Sebastien Alaiwan authored
      This option is obsolete and confusing now that the LBD coding path
      can be disabled at build time (--disable-lowbitdepth).
      Removing it makes the encoder/decoder behaviours symmetric, and
      prevents the "--test-16bit-internal --test-decode=fatal" mismatch.

      Copy ctx in get_entropy_contexts_plane for lv_map · fb42c7fa
      Angie Chiang authored
      This will fix Assertion in get_txb_ctx() for invalid sign value
      After fixing this bug, we have around 0.2% gain on lowres.
      With cb4x4 on only, lv_map provides 1.538% gain on lowres.
      With cb4x4 + chroma_sub8x8, lv_map provides 1.468% gain on lowres.

      Refactor sub8x8 tx size RD for daala-dist · 30a2c5f2
      Yushin Cho authored
      For a tx size RD search with partition size >= 8x8 and tx size < 8x8,
      daala-dist function is applied to the whole partition after all tx blocks are encoded
      instead of each 8x8 sub block of the partition.

      Remove deprecated high-bitdepth functions · 31c66502
      Sarah Parker authored
      This unifies the codepath for high-bitdepth transforms and deletes
      all calls to the old deprecated versions. This required reworking
      the way 1d configurations are combined in order to support rectangular
      There is one remaining codepath that calls the deprecated 4x4 hbd
      transform from encoder/encodemb.c. I need to take a closer look
      at what is happening there and will leave that for a followup
      since this change has already gotten so large.

      Fix some UBSan warnings · 185575a7
      David Barker authored
      * Make intermediate arrays in av1(_highbd)_warp_affine_c signed,
        to avoid integer overflow when multiplying an 'unsigned int'
        by a negative 'int' value.
      * Pad out arrays in masked_variance_test.cc so that the array
        stride is a multiple of 16 bytes.
        This fixes some UBSan errors in masked_variance_intrin_ssse3.c
        related to unaligned loads of 32-bit values.

      Add a new experiment "rect-intra-pred". · 766a389b
      Urvang Joshi authored
      Earlier, intra prediction for rectangular blocks was performed by
      running two steps of prediction on square sub-blocks.
      With this experiment, we do proper intra prediction for rectangular
      blocks. This ensures that we make use of all available neighboring
      pixels especially for directional modes. For this, all the intra
      predictors were updated to work with rectangular transform block sizes.
      Performance improvements are small but free of cost:
      All Intra frames:
      lowres: -0.126
      midres: -0.154
      Video Overall:
      lowres: -0.043
      midres: -0.100

      Make loop-restoration compatible w/ frame_superres · 2dd982e4
      Debargha Mukherjee authored
      When frame_superres is on, loop-restoration should work
      on the size of the upscaled frame and not on the internal
      width and height in the common structure. This patch
      makes the necessary changes on the encoder and decoder
      side to enable that.

      is_directional_mode: Check for directional modes directly. · 875a6675
      Urvang Joshi authored
      Earlier, the condition was negating all non-directional modes to check
      if a mode is directional. This was error-prone, e.g. when a new
      non-directional mode is added.
      By checking for directional modes directly, we avoid such errors.
