      The element of "idx" in the data structure of RefBuffer is a
      connection between AV1_COMMON::RefBuffer and
      AV1_COMMON::BufferPool::RefCntBuffer.
      
      It is being used currently in many places in both the encoder and the
      decoder. "idx" is not only used to track whether a reference buffer is
      alive, but also serve as the connection to RefCntBuffer which contains
      info that RefBuffer itself cannot access.

      Make convolve_round work with warped_motion · 05685e9a
      Angie Chiang authored
      Warped_motion doesn't go through inter_predictor() function to
      generate prediction where convolve_round is activated.
      Therefore, we could avoid doing post rounding when the
      warped_motion mode is on.
      
      We use do_post_rounding to indicate whether post rounding is
      needed

      [CFL] Support for skip_chroma_rd in CB4X4 · 2c317905
      Luc Trudeau authored
      CFL is disabled when skip_chroma_rd is enabled. This is done by reusing
      the logic in CB4X4. To facilitate integration, the skip logic used in CfL is
      moved inside the read/write functions.

      Palette: avoid memory leak with encoder buffers · 5d493143
      hui su authored
      For multi-thread encoding, previously the encoder buffers are
      allocated at every frame, but only freed at the end of encoding,
      causing memory leaks.

      Palette: Special case for 2 unique colors. · 773e3542
      Urvang Joshi authored
      When a block only contains 2 unique colors, there's no need to run
      K-means, as 'lb' and 'ub' can directly be used as the centroids.
      
      Two benefits:
      1. Encoding will be faster for this special case, and
      2. Can potentially avoid sub-optimal/duplicate centroids generation
      (due to integer rounding) when 'ub' and 'lb' values are very close.

      [CFL] Change cfl_load to use width and height · 30596fb2
      Luc Trudeau authored
      Since the size used with cfl_load can either be based on the transform
      block size and the prediction block size, width and height are used as
      parameters instead of TX_SIZE.
      
      This resolves a problem where cfl_compute_alpha_ind was reading
      uninitialized memory.

      Palette: Handle case of too few unique centroids. · 5fb95f7d
      Urvang Joshi authored
      Even though number of unique colors in a block may be at least
      PALETTE_MIN_SIZE, sometimes the K-means can generate fewer than
      PALETTE_MIN_SIZE unique centroids due to integer rounding.
      
      This was resulting in "k - PALETTE_MIN_SIZE" being negative and using
      that as an index into palette_y_size_cost array was causing a UBSan
      error.
