      [NORMATIVE] Limit valid frame distance for mfmv projection · 248b9563
      Jingning Han authored
      Set the maximum frame distance to be 32. If a reference motion
      vector needs to span across two frames at distance more than 32,
      drop the use of this reference motion vector.
      This also clears ubsan warnings in unit tests.

      [NORMATIVE][intra-edge2] Add header disable flag · db5eb4cd
      Joe Young authored
      Add a flag disable_intra_edge_filter in the uncompressed header
      of key/all-intra frames to disable corner, edge, and upsampling
      filter with ext-intra modes.
      This adds an experiment flag: intra_edge2

      Consolidate all post_rounding for compound modes · d69927da

      The do_post_rounding flag can now be removed since it is equivalent
      to is_compound.

      Clean up and use do_post_rounding consistently · c3a8ae46
      Debargha Mukherjee authored
      This patch simplifies the setting and use of the do_post_rounding
      flag consistently across all convolve/warp operations. It is always
      set now to 1 for compound modes, but the masked blending operation
      can subsequently turn it off.
      To accomplish this, for the warped case, the use of the conv_params->dst
      buffer is made consistent with the other non-warp convolves,
      in the sense that it is used only when is_compound is 1.

      store up to one mv that points towards last_frame side, instead
      of storing up to two mvs each corresponds to one side.

      [NORMATIVE] Add decoder support for frame_refs_signaling · b57fee02
      Zoe Liu authored
      One bit is added to the frame header, to signal whether the references
      for inter frames will be short-signaled.
      When the bit is set, only 6 bits are used at the frame header level to
      signal the choices of LAST_FRAME and GOLDEN_FRAME out of the eight
      buffered references. All the other 5 references will be specified
      using the frame offset info. Hence, compared to the baseline, the use
      of frame_refs_signaling provides 2 scenarios:
      (1) Reference short-signaling:
          3*7 - (1+3*2) = 14 bits are saved in the frame header;
      (2) Reference regular-signaling:
          1 bit is added to the frame header.

      Fix and clean up warp filter SIMD code · fa904a09
      Imdad Sardharwalla authored
      - Fixed SSE4.1 implementation of the highbd warp filter.
      - Removed the SSE2 and SSSE3 implementations of both the lowbd and highbd
        versions of the warp filter, as these will not work with CONFIG_JNT_COMP=1.
        (There are now only SSE4.1 implementations)
      - The warp filter tests have been correspondingly updated.

      Fix jnt_comp simd function in warp · 8f726212
      Cheng Chen authored
      Change _mm_srl_epi32 to _mm_sra_epi32. The difference is keeping
      sign bits in shifting. Otherwise there are mismatchings between simd and c
      functions, caught by unit tests.
      The other change is fix a typo.

      [NORMATIVE] Enable mfmv for low latency settings · a127b42d
      Jingning Han authored
      Tested in the low latency setting. Comparing the three options:
      (1). Cut off temporal mv altogether.
      (2). Use collocated mv referncing.
      (3). Use mfmv referencing.
      The current baseline is using (1).
      The results are:
      (2) improves the compression performance over (1) by -0.59% for
      lowres and -0.65% for midres.
      (3) improves over (1) by -1.05% for lowres and -1.43% for midres

      [NORMATIVE] Unify context design for single ref · 3b353474
      Zoe Liu authored
      The CL makes the context design for single reference frame coding the
      same as that for the compound reference frame coding. There are 3
      contexts designed for each of the binary symbols for the single
      reference frame scenario, and the designed contexts simply rely on the
      counts of the references used in the neighboring two blocks.
      Once this CL is merged, the coding of the reference frames, regardless
      of single prediction or compound prediction, will all follow the same
      context design pattern for all the binary symbols. The design logic is
      much simpler and the lines of code for each binary symbol context
      identification are reduced by 80%.
      Further, this CL has obtained a small coding gain for 30 frames with
      the default coding tools:
      lowres: avg_psnr -0.015%; ovr_psnr -0.021%; ssim -0.002%
      midres: avg_psnr -0.108%; ovr_psnr -0.139%; ssim -0.135%

      [NORMATIVE] Fix top right mv check condition for VERT_A partition · 56066252
      Jingning Han authored
      When a coding block runs VERT_A partition, the coding order does
      not follow raster order. This requires a special handle on the
      bottom left square block to disable its reference towards the
      top-right corner. Prior to this change the codebase would disable
      the bottom-right square, as well as the right rectangular blocks,
      from referencing the top-right mv. This commit fixes such check
      condition to allow the right rectangular block to access the top
      right mv.
