      Miscellaneous fixes for var-tx · 16c64e33
      David Barker authored
      Lots of small bug fixes, mainly around the transform size coding:
      * The loop filter was accidentally using the non-subsampled
        block size for the V plane, due to comparing a plane index
        (0, 1, or 2) against PLANE_TYPE_UV (== 1)
      * We allowed an initial update of the transform partition probabilities
        even on frames where we know they will never be used
        (because tx_mode != TX_MODE_SELECT).
        Further, these probabilities would not be reverted at the end
        of the frame, leading to the probability delta persisting across frames.
        Change this to behave more like the non-var-tx transform size coding,
        where probability deltas are only coded for frames with
        tx_mode == TX_MODE_SELECT, and the deltas only apply for one frame.
      * Fix decoder for the case where the video as a whole isn't lossless,
        and we have tx_mode == TX_MODE_SELECT, but the current segment
        *is* lossless.
        Note that the encoder already does the right thing in this case.
      * Don't allow the transform splitting to recurse "below" 4x4.
        This is really just a refactor, but means we can increase the
        maximum depth when subdividing rectangular transforms if we
        want to, whereas the previous code would have needed special cases
        for 4x8 and 8x4 transforms.
      * Finally, when we hit the maximum splitting depth, don't update
        the counts as if we had coded a 'no split' symbol.

      Encode loop restoration coefficients per tile · 09b5b168
      Rupert Swarbrick authored
      This is a baby-step towards encoding the coefficients at the start of
      superblocks at the top-left of loop restoration tiles. Note that this
      patch causes us to reset "wiener_info" and "sgrproj_info" at each tile
      boundary, which will cause a performance drop.
      This is necessary because, in order for tiles to be processed in
      parallel, we cannot delta-encode coefficients across tile boundaries
      if the coefficients are signalled within tiles. We could probably do
      better than the current patch by, say, delta-encoding against previous
      This patch also fixes up the costing in pickrst.c to match

      Refactor setup_ref_mv_list · d797ea9e
      Yunqing Wang authored
      This patch eliminates the is_inside() checking for each neighouring
      block in scan_row_mbmi() and scan_col_mbmi(). Instead, in
      setup_ref_mv_list(), find maximum above row_offset and left col_offset
      for current block, and use them to decide which above rows and left
      columns to search on. This patch doesn't change bitstream. No
      noticeable speedup is seen.

      [CFL] Fixed negative rounding in scaled_luma · 9c0e9eac
      Luc Trudeau authored
      Since the scaled luma can be negative, ROUND_POWER_OF_TWO_SIGNED must be used.
      This changes the behavior from rounding toward -infinity to rounding towards 0.
