      [dist-8x8] Bug fix - exclude invisible pixels · 2f025aae
      Yushin Cho authored
      There were two places where invisible pixels are included
      when calculating distortion with dist-8x8 is turned on.
      Those are bugs and fixed by this commit.
      
      1) When av1_dist_8x8() is called in dist_8x8_sub8x8_txfm_rd()
      - New assert() are also added to detect any failures in the future.
      
      2) Inside av1_dist_8x8() and av1_dist_8x8_diff(), with tune-metric == PSNR.

      Add a new layout for HORZ/VERT_A/B partitions · 3dd33911
      Rupert Swarbrick authored
      This hides behind --enable-ext_partition_types_ab. When that flag is
      set, the mixed partitions change from
      
         +-+-+---+          +-+-+---+
         |   |   |          | | |   |
         |---+   |    to    | | |   |
         |   |   |          | | |   |
         +-+-+---+          +-+-+---+
      
      (that's PARTITION_VERT_A; other partitions change similarly).
      
      Since 128x32 and 32x128 block support hasn't yet been merged, this
      patch also temporarily disables these partitions for 128x128 blocks.

      Update default probs for reference frame coding · 6905dc79
      Zoe Liu authored
      The updates in this CL are for the scenario when ext-comp-refs is off.
      
      For --disable-global-motion --disable-ext-tx --disable-ext-comp-refs
      --disable-convolve-round, the patch obtains a small BDRate gain for
      PSNR: lowres -0.08%; midres -0.05%

      Make LOOPFILTER_LVL support segment · d8184dae
      Cheng Chen authored
      Experiment LOOPFILTER_LVL has 4 deblocking filter levels for:
      y plane horizontal, y plane vertical, u plane, and v plane.
      
      The patch supports segment updates for each of the four filter levels.

      Don't work in TX64X64 blocks on a subsampled chroma plane · 4e7b7d6f
      Rupert Swarbrick authored
      With ext-partition and tx64x64 enabled, the encoder could choose
      TX_64X64 to encode the transform for a subsampled plane of a
      BLOCK_128X128 block. This broke an assumption in the nested loop in
      write_tokens_b and also caused bug 827 (with a rather cryptic
      failure).
      
      This patch changes get_vartx_max_txsize to ensure that the encoder and
      decoder don't think they can use TX_64X64 in this situation. It also
      adds a couple of assertions to the loop mentioned above so that if
      something comes unstuck it'll be much more obvious what went wrong.

      fix one bug in the decoder header initization · dd8df163
      Ryan authored
      1. seg->temporal_update flag is only read when seg->update_map flag is
      set to 1 in the bit stream. in case update_map flag is different from frame
      to frame, the temporal_update flag will not be reset to 0 when
      update_map flag changed from 1 to 0. i.e, the previous temporal_update
      flag will be used in the later process. in the read_inter_segment_id
      function, temporal_update flag is used to read the segment id. it will
      cause bit stream parsing error.
