      Add speed feature to reduce tx size search depth · edc7346f
      Debargha Mukherjee authored
      The speed feature simply restricts the number of depths
      searched. Currently it is turned on by default for speeds>=1.
      The coding efficiency impact (tested on lowres 30 frames) seems
      to be ~0.15% and the speedup is in the order of 15%.

      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.

      Let jnt_comp work with compound_segment. When frame distance weights
      are used, compound_segment blending is turned off. When normal compound

      select between {frame distance weights, normal compound,
      compound_segment blending}.

      When needed, fallback regular interp filter at reconstruction stage.
      
      Such bitstreams are valid.
      However, as we don't expect aomenc to generate them,
      print a helper warning.

      Find warped reference MV · 97d6a37e
      Yunqing Wang authored
      While finding the reference MV for a block, if one neighbouring block's
      motion mode is warped motion mode, instead of directly adding that
      block's MV to the candidate MV list, we use that neighbouring block's
      warped motion parameters to compute a MV for the center point of the
      current block, and then add that MV to the candidate MV list.
      
      Borg test result:
                   avg_psnr ovr_psnr ssim
      cam_lowres:  -0.507   -0.514  -0.685
      lowres:      -0.114   -0.122  -0.180
      
      The change is added under ext_warped_motion config flag.
