      is_directional_mode: Check for directional modes directly. · 875a6675
      Urvang Joshi authored
      Earlier, the condition was negating all non-directional modes to check
      if a mode is directional. This was error-prone, e.g. when a new
      non-directional mode is added.
      
      By checking for directional modes directly, we avoid such errors.

      DPCM intra coding experiment · b8a6fd6b
      hui su authored
      Encode a block line by line, horizontally or vertically. In the vertical
      mode, each row is predicted by the reconsturcted row above;
      in the horizontal mode, each column is predicted by the reconstructed
      column to the left.
      
      The DPCM modes are enabled automatically for blocks with horizontal or
      vertical prediction mode, and 1D transform types (ext-tx).

      Add CONFIG_INTERINTRA flags and reduce # of interintra modes to 4 · 4d26acb4
      Yue Chen authored
      Use CONFIG_INTERINTRA to properly separate interintra from the basic
      ext_inter experiment.
      When macro REDUCE_INTERINTRA_MODES is 1, only 4 ii modes are enabled
      so as to reduce the complexity overhead.
      (Right now the flag is off)

      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

      Make ext-inter use new rectangular intra predictor · 839467f4
      David Barker authored
      Now that https://aomedia-review.googlesource.com/#/c/6729/
      has been merged, build_intra_predictors_for_interintra() is
      now redundant, so replace it by a direct call to
      av1_predict_intra_block() and remove the old function.
      
      Reset rect_interintra back to 1.
      
      To do this, we need to make the intra predictor take a
      BLOCK_SIZE instead of a TX_SIZE. This is because we need to
      be able to predict 32x64 and 64x32 blocks, but there is no
      TX_32X64 or TX_64X32.
      
      No effect on output or performance.

      The word 'pick' is usually used in functions that make decisions where
      the bitstream allows multiple legal choices, and not to limit the
      bitstream format itself.
