      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.

      Dominic Symes authored
      This adds the tool CONFIG_MAX_TILE
      Uniform tiles are implemented using power of two number of rows or columns.
      Maximum number of rows or columns is 64
      Explicit tiles will follow in a later commit once the command line API is updated for this

      [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.
      Results on Objective-1-fast (Compare to master with CfL disabled)

      [CFL] Use MAX_NUM_TXB_SQUARE instead of MAX_NUM_TXB · f1cf7178
      Luc Trudeau authored
      MAX_NUM_TXB represents the maximum number of transform blocks in 1
      dimension. CfL requires the maximum number of transform blocks in 2
      dimensions. As such, we now use MAX_NUM_TXB_SQUARE instead of the
      erroneous MAX_NUM_TXB for the average buffer.
      There's an assert guarding for overrun on the average buffer.
      This fix stops assertions on 4:4:4 sequences. This patch does
      not alter AWCY results as AWCY only covers 4:2:0 sequences (for
      which MAX_NUM_TXB turns out to be sufficient).

      [CFL] Replace Magic Numbers with Constants · 03b7e7d5
      Luc Trudeau authored
      Added CFL_SUB8X8_VAL_MI_SIZE and CFL_SUB8X8_VAL_MI_SQUARE to replace the
      magic numbers previously used. Also, CFL_SUB8X8_VAL_MI_SIZE goes from 2
      to 4 to support the upcoming EXT_PARTITION_TYPE experiment.

      Convert to PREDICTION_MODE for is_directional · f24a35f8
      Luc Trudeau authored
      Recent code added in EXT_INTRA wasn't compatible with CfL,
      because it assumed that the PREDICTION_MODE was the same
      for luma and chroma, which is not the case with CfL.
      UV_PREDICTION_MODE must be converted to PREDICTION_MODE for
      av1_is_directional_mode function.
