      Make plane generic over pixel component type · 8057ee7c
      Romain Vimont authored
      In order to support both u8 and u16 for plane components, make the Plane
      structure generic over the component type. As a consequence, many other
      structures and functions also become generic.
      Some functions are not u8-compatible yet, although they have been make
      generic over the component type to make the compilation work. They
      assert that the size of the generic parameter is 16 bits wide.
      For this reason, the root context structure is unconditionally created
      as Context<u16> for now.

      Fix to LRF cropping · 7c158f82
      Monty authored and Monty Montgomery's avatar Monty Montgomery committed
      Recent simplification that eliminated clipped_cfg broke the loop
      restoration filters and I didn't notice as it's not enabled by default yet.
      This fixes the cropping for chroma in the SGR and Wiener filters.

      Store restoration units contiguously · 8503cea4
      Romain Vimont authored
      The "matrix" of restoration units was stored in a vector of vectors.
      To avoids an additional indirection for each row, store them in a
      contiguous array instead. Besides the (theoretical) performance benerit
      for every access, this will simplify the implementation of tiled-views
      which have to expose non-overlapping parts of the "matrix" via unsafe
      Also, since its size is constant (although not known at compile-time),
      replace the vector by a boxed slice.

      Remove clipped_cfg from RestorationState · 07032e6b
      Romain Vimont authored
      A RestorationState stores a matrix of restoration units per plane. The
      restoration unit associated to a superblock may be retrieved from a
      superblock offset.
      Although this mapping is independant of subsampling, the superblock
      offsets were always converted to plane coordinates, which required to
      handle subsampling nonetheless. As a consequence, a PlaneConfig instance
      associated to RestorationPlane was necessary to find a restoration unit
      from a superblock offset.
      Instead, store the (log2) number of superblocks per restoration unit, to
      be able to retrieve a restoration unit from a superblock with a simple
      shift (without any subsampling information).
      That way, we can remove the PlaneConfig associated to RestorationPlane,
      which will simplify tiling.

      Use non-padded dimensions from FrameInvariants · 54526343
      Romain Vimont authored
      The loop restoration filter needs the dimensions of the non-padded
      frame, that only FrameInvariants knows.
      On construction, RestorationState created a clipped version of the
      PlaneConfigs, that was used in lrf_filter_frame() to get the non-padded
      Instead, directly pass &FrameInvariants to lrf_filter_frame().
      This paves the way to remove clipped_cfg from RestorationState entirely,
      to simplify tiling.

      Make RestorationState derive Debug · 37a62634
      Romain Vimont authored
      FrameState is Debug. In order to embed RestorationState into FrameState,
      make it Debug too.

      Do not borrow full FrameState for LRF · 90bed0bf
      Romain Vimont authored
      Once RestorationState will be stored into FrameState, it will not be
      possible to borrow a FrameState while its RestorationState is mutably
      In particular, this prevents passing a FrameState to a non-const
      RestorationState method.
      For lrf_optimize_superblock(), which is not implemented yet, just remove
      the FrameState parameter.
      For lrf_filter_frame(), only borrow the "rec" field instead of the whole

      Remove duplicate fields · d92d9a2a
      Romain Vimont authored
      lrf_type and unit_size are per-plane values, there is no need to
      duplicate them as arrays in RestorationState.
