      cb4x4: Fix indexing of tx_size counts. · fe0fb1d9
      Timothy B. Terriberry authored
      Create named constants for the minimum TX_SIZE used in the luma
      plane, as well as the minimum allowed TX_SIZE for which we have to
      explicitly code a selection (i.e., one larger than the minimum luma
      TX_SIZE).
      
      Then, use these constants consistently with tx_size_to_depth() to
      index the tx_size counts in FRAME_COUNTS, and also consistently use
      TX_SIZE named constants to index the tx_size_implied counts.
      
      Failing to index these counts correctly can, e.g., cause tx_mode to
      be chosen incorrectly.

      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).

      new_tokenset: Add missing blockzero_probs for cb4x4. · 90ed98f9
      Timothy B. Terriberry authored
      cb4x4 adds a new TX_2X2 to the TX_SIZES enum, which offsets the
      indexing of blockzero_probs. Add a set of default probabilities for
      this case (simply copied from the TX_4X4 probabilities).
      
      These will only be used if chroma_2x2 is enabled (though moving the
      other probabilities back to their correct offset will affect all
      other sizes).
      
      This is an encoder-only change.

      frame_superres: Refactor pre-encode frame size set · bc189939
      Fergus Simpson authored
      Before this commit set_frame_size decided on the frame size to use and
      then set it. It has been changed to just take an arbitrary size to make
      it more flexible.
      
      The decision of what size to use has been moved to the new
      set_scaled_size and existing av1_calculate_superres_size.
      
      setup_frame_size implements the old logic of getting the scaled size,
      then superres size, then setting the frame to use it.
      
      This change will make post-encode upscaling possible using
      set_frame_size since it can now be given a target resolution.

      Add configurations for hbd identity transform · 3eed4175

      This adds the proper cfgs to av1_{inv/fwd}_txfm1d_cfg for
      the identity transform so all hbd transforms can use
      the same codepath. This has no impact on performance
      since the new identity transforms that correspond with
      the cfgs are not yet being called. Once this is checked in,
      we should be able to delete all deprecated transform functions
      and have a single code flow for all hbd transforms.
