      Do not crash on tiny images · 8412ff0b
      Romain Vimont authored
      Subsampled motion estimation may not work for a block size smaller than
      the input frame (e.g. block 64x64 on a 40x40 input).
      This is currently rarely a problem in practice, but with tiling, the
      tiles on right and bottom borders may be small and crash the encoder.

      Pass plane and offset to get_intra_edges() · b8063c41
      Romain Vimont authored
      In order to guarantee that a slice never exceeds its parent,
      EdgedPlaneSlice was introduced by #1082.
      However, it added complexity, and happens to be insufficient to adapt
      get_intra_edges() for tiling (we can't retrieve the tile dimensions).
      Instead, pass both the Plane (in the future, the plane region associated
      with the tile) and the plane offset. It's simpler, and it still does not
      require a slice to exceed its parent.

      Pass CDFContext by reference in ContextWriter · 265889fa

      With tiling, the lifetime of CDFContext will exceed that of

      Move FrameBlocks out of BlockContext · 8e063aaf
      Romain Vimont authored
      With tiling, the lifetime of FrameBlocks will exceed that of
      BlockContext (which will exist only during tile encoding).
      Therefore, create it separately, and make BlockContext reference it.

      Pass FrameBlocks instead of BlockContext · 3c29f358
      Romain Vimont authored
      FrameBlocks is part of the BlockContext structure. Many functions which
      used only the FrameBlocks (but not the other BlockContext fields)
      received a reference to the whole BlockContext as parameter.
      FrameBlocks will survive tiles-encoding: it will be accessed through a
      tiled version for each tile, then frame-wise after all tiles are
      However, BlockContext will only be used tile-wise: there will be one
      instance per tile, destroyed once the tile is encoded. Therefore,
      frame-wise functions may not receive the whole BlockContext anymore
      (all tile-specific BlockContext instances won't exist anymore).

      Use operator[] instead of at() and at_mut() · 9aa21995

      Move methods from BlockContext to FrameBlocks · 2e9aacda
      Romain Vimont authored
      Some BlockContext methods are specific to FrameBlocks, so move them.
      With tiling, the lifetime of FrameBlocks will exceed that of
      BlockContext (which will exist only during tile encoding).
      This paves the way to move FrameBlocks out of BlockContext.

      Create RefType enum. · db58658a
      Thomas Daede authored
      Moves all functions that previously used usize to this type.
      Instead of direct conversions to a slot number, use a to_index fn.
      This also changes the size of the global mv state and context
      ref counting arrays as they don't need LAST_FRAME.
