      Missing features:
      * RDOPT (Forced on for certain blocks)
      * Any form of border extension
      * Non MI sized right and bottom edges
      * MV prediction
      
      Present features:
      * Force intrabc for some blocks

      Harmonize ext-inter and ref-mv · 3dfba994
      David Barker authored
      This changes the behavior of the ext-inter compound modes
      as follows:
      * NEAREST_NEARESTMV, NEAR_NEARMV, NEW_NEWMV, ZERO_ZEROMV
        work the same as the corresponding compound modes without
        ext-inter
      * NEAREST_NEWMV and NEW_NEARESTMV keep their current behavior,
        which is to use the first ref-mv candidate pair for their
        particular reference frames
      * NEAR_NEWMV and NEW_NEARMV select between the second, third,
        and fourth candidate pairs.
      * NEAREST_NEARMV and NEAR_NEARESTMV use the first candidate
        pair for the NEAREST component and the second, third, or
        fourth candidate pair for the NEAR component.
      
      Also do some minor refactoring and fix compile errors
      with --enable-ext-inter --disable-ref-mv

      Fix some rdopt bugs in ext-inter · cb03dc34
      David Barker authored
      * Refactor write_inter_mode and cost_mv_ref slightly
      
      * In handle_inter_mode: When discount_newmv_test returns 1,
        ext-inter is enabled, and we're costing up a compound mode,
        we would previously call cost_mv_ref with mode=NEARESTMV and
        comp_pred=1. But this is inconsistent when ext-inter is enabled!
      
        Fix this by changing the behaviour of cost_mv_ref to (effectively)
        derive comp_pred from the mode passed in, and switch to
        mode=NEAREST_NEARESTMV in the above case.
      
      * Fix incorrect motion vector costing for some compound modes
      
      * Fix a case where compound blocks were mis-costed. This primarily
        affects ext-inter *without* wedge or compound-segment enabled,
        but should still have some small impact when those experiments
        are enabled.
      
        The cause of this is that we only spend bits to send the
        interinter compound type if is_any_masked_compound_used(bsize)
        returns true. But the rdopt loop forgot to check this condition
        in one case.

      Refactor gm/wm/obmc for cleaner warping interactions · 4c10a3c2
      Sarah Parker authored
      This creates a central function which defines when a
      block should be warped. It also refactors the
      WARPED_MOTION code so that all calls to av1_warp_plane
      happen in the same location.
      
      No change in performance.

      Fix invalid tx_type returned by get_tx_type · 18ad894a
      Angie Chiang authored
      1) Check if tx_type is valid in get_tx_type
      
      2) Remove scan_order from rdcost_block_args
      When lv_map is on, scan_order depends on tx_type but tx_type is
      not decided before entering block_rd_txfm yet. Therefore
      assigning a scan_order into rdcost_block_args and then passing it
      into block_rd_txfm will cause error.
      
      3) Pass correct index into intra_mode_to_tx_type_context in
      get_tx_type
      
      This CL doesn't affect baseline/supertx's stats.

      Modify choose_tx_size_type_from_rd for lv_map exp · f1cb075d
      Angie Chiang authored
      The tx_type becomes dummy when lv_map is on. The tx_type search
      will be performed in av1_search_txk_type() and the results will be
      stored in txk_type[]
      
      In choose_tx_size_type_from_rd, we use best_txk_type[] to record
      the best search result within different tx_size.

      Use block_idx rather than block_raster_idx · 752ccce7
      Angie Chiang authored
      1) block_raster_idx is actually raster order only when tx_size
      is TX_4x8.
      It's very specific, so we should put it near to the place it's
      actually used.
      
      2) Sync the meaning of block_idx on encoder/decoder sides
