      Return 0 when eob is 0. It is possible that when eob is 0, the
      fed in quantization matrix is uninitialized in the rate distortion
      optimization process.

      Use integer multiplier to replace division in mfmv · 00d5868d
      Jingning Han authored
      Use integer multipliciation to replace the division operation in
      the linear projection in mfmv. The coding performance change is
      around 0.01% level.

      Search for deblocking filter level for superblock · f572cd30
      Cheng Chen authored
      Search and pick filter level for each superblock after the entire
      frame has been encoded. And then apply loop filtering using
      selected filter levels.
      Now it can't work with LOOPFILTER_LEVEL. Y, U, V planes share the
      same filter level.
      Per superblock, filter levels are signaled via bitstream.
      Future work: move selecting filter level into each superblock
      rather than wait for the whole frame encoded.

      fix the calculation for super_block_upper_left · 676c25cd
      Ryan authored
      the original calculation for super_block_upper_left calculation is
      wrong. this flag is true even for 32x32 block boundary. also it is not
      consistent with other places where this flag is calculated.

      new-multisymbol: Don't signal ext-comp-refs probs · 037ee412
      David Barker authored
      Currently, when new-multisymbol and ext-comp-refs are
      both enabled, the comp_ref_type_prob and uni_comp_ref_prob
      arrays are forward updated in the compressed header, but
      their values are never used.
      We can save a tiny bit of space by not signalling the
      forward updates at all; as a side benefit, we can wrap
      the whole of read_frame_reference_mode_probs() in
      a #if !CONFIG_NEW_MULTISYMBOL block.
      Note: It seems the encoder already does this; I think
      the reason it doesn't cause mismatches is because we
      effectively pad the compressed header out to a full byte,
      and av1_diff_update_prob() reads a bit with a very high
      probability of being 0.

      [CFL] CfL for Intra frames only · a66a2cb2
      Luc Trudeau authored
      This commit serves as a baseline to test CfL in video sequences. This
      starting baseline uses CfL only in intra frames. This allows to measure
      the contribution of CfL in intra frames over the whole video sequence.
