      Properly handle the tile load size writing · 2e7d66d9
      Jingning Han authored
      Properly handle the tile load size writing operations in ext-tile
      when large-scale-tile is on and off. This fixes an enc/dec mismatch
      issue when both ext-tile and obu are turned on.

      Fix ext-tile and obu · 5737b4c0
      Jingning Han authored
      Fix the broken unit test when ext-tile and obu are both turned on.
      The test failure was due to the merge of CONFIG_ADD_4BYTES_OBUSIZE.
      This solves the unit test failure cases when cm->large_scale_tile
      is on.

      Add encoder support to fwd-kf · b499120e
      Zoe Liu authored
      Encoder now writes the binary symbol for show_existing_frame to
      indicate the value of reset_decoder_state. The default value now
      is set as zero regardless. This enables the bitstream match with
      the decoder.
      
      With this patch when fwd-kf is enabled, one additional bit is
      signaled at the frame header for show_existing_frame, but without
      any coding performance impact.

      to incur more than 0.3% compression performance loss. Hence remove

      Use the number of pixels in a block as context, rather than the bsize
      itself. The rectangular blocks therefore share the same context, e.g.

      The number of contexts is reduced from 10 to 7.

      Enable CDEF for chroma for 4:2:2 and 4:4:0 · ab6c9c77
      Steinar Midtskogen authored
      This enables CDEF for chroma when the horizontal and vertical
      subsampling differs.  Since the direction search is only performed in
      luma, the following corrections to the direction index are done for
      chroma to correct the distortion resulting from the subsampling:
      
      4:2:2:   4:4:0:
      0 -> 7   0 -> 1
      1 -> 0   1 -> 2
      2 -> 2   2 -> 2
      3 -> 4   3 -> 2
      4 -> 5   4 -> 3
      5 -> 6   5 -> 4
      6 -> 6   6 -> 6
      7 -> 6   7 -> 0
      
      This improves the chroma PSNR BDR by about 2% for 4:2:2 content at
      cpu-used=4, low delay configuration.  4:2:0 and 4:4:4 content is
      unchanged.

      add new experiment loopfiltering_across_tiles_ext · 7bb501d5
      Lei authored
      based on the latest discussion in the HW working group about how loop
      filter should be integrated with tiles, the following decisions have been
      made:
      1. two seperated flages should be added for
      loop_filter_across_tiles_enabled for horizontal tile boundary and
      vertical tile boundary.
      2. encoder and decoder should only check these two flags to determine
      whether loop filtering (including deblocking, CDEF and loop restoration)
      should cross tile boundaries (vertical and/or horizontal) or not
      regardless the horitontal depepdent tile flag.
      
      This change list implemented the support for two seperated
      loop_filter_across_tiles_enabled flags for vertical and horizontal tile
      boundaries. The new experiment is disabled as default before it is
      adopted.

      Expand skip mode support for all comp frames · 4b847e19
      Zoe Liu authored
      All compound predicted frames now have the choice to either turn on
      or off the use of the skip mode. The current encoder design only
      turns on the use of skip mode when the temporal distances of the two
      reference frames to the current frame are only different by 1.
      
      This patch also includes a fix on the calculating of the temporal
      distance between the two reference frames to the current frame for
      skip mode.
      
      Performance wise, this patch does not have noticeable impact as the
      encoder stays with the same choice with the frame-level skip mode
      flag.
