      Remove the use of prev_frame_mvs for mfmv · 294f59d0
      Zoe Liu authored
      The experiment of mfmv has already extensively leveraged the use of
      the motion vectors from the reference frames, hence there is no need
      to further add the motion vectors from the previous frame to serve
      as the motion vector reference candidates, let alone such motion
      vectors have not taken into account of the use of frame offsets.
      
      Experimental results collected so far have shown this patch has zero
      coding performance impact.

      Use tx_size 1 level down for transform type search · 90024e44
      Sarah Parker authored
      This addresses an inconsistency between the set used
      to decode the tx_type in the bitstream and the set used
      for the tx_type search. Previously, the set used to
      read/write the tx_type was based on the smallest tx_size
      in the vartx partitioning, but the search uses a set
      based on the largest possible tx_size. This patch
      changes the tx_type search to use the transform type
      set associated with the tx_size 1 recursive level down from
      the max square tx_size to make the search more consistent
      with the bitstream syntax. If a tx_size is selected for an
      invalid tx_type, DCT_DCT is used for that partition instead.
      
      This patch also adds assertions to all exposed transform
      functions to ensure that no illegal transform type/size
      combinations occur.
      
      This currently gets a 0.1% drop in performance on lowres.
      The drop is due to the reduction of the tx_types available
      for 32x16 and 16x32 transform sizes. Before this patch,
      32x16 and 16x32 transforms were getting assigned a
      set of 12 tx_types, some of which we did not intend to
      support for these sizes.

      Add decoder support to ext_skip · f704a1c8
      Zoe Liu authored
      At the frame header level, add the checking on whether an inter-coded
      frame allows the use of 'skip_mode'. At the block level, add the
      decoding of 'skip_mode' for all the blocks if 'skip_mode' is allowed
      for the current frame. If 'skip_mode' is set, no further bit needs to
      read out, and the block is set as:
      - Inter-coded in compound mode;
      - With the nearest forward and backward reference frames;
      - In NEAREST_NEARESTMV mode;
      - In SIMPLE_TRANSLATION motion mode;
      - In COMPOUND_AVERAGE compound type; and
      - Skip set for residual.
