      Separate frame context index for different frame types · 7c1c078d
      Jingning Han authored
      This commit makes the encoder to use different frame context index
      for different frame types. In the baseline setting, it sets the
      frame context index of the overlay frame to be different from other
      regular inter frames. In the ext-refs setting, it further allows
      the backward reference frame to use a different index.
      It improves the compression performance for both settings.

      Add code to compute in-order mappings for tokens. · 4531b85a
      Nathan E. Egge authored
      Add av1_indices_from_tree() function that computes a forward and inverse
       mapping of the tree leaf-node symbols to their in-order traversal.
      This is necessary because many of the aom_tree binary trees have their
       leaf nodes out of order (e.g., an in-order traversal of a tree with n
       nodes does not start at symbol 0 and go to symbol n - 1), but the CDFs
       created by tree_to_cdf() are indexed in-order.

      Add the use of new reference frames at encoder in EXT_REFS · 9c1e2f92
      Zoe Liu authored
      In the experiment of EXT_REFS, add the use of the 3 extra reference
      frames, including the 2 forward reference frames LAST2 and LAST3, and
      the one backward reference frame BWDREF, for the encoding.
      For lowres, EXT_REFS achieves following bitrate saving on overall PSNR
      compared against baseline:
      Avg: -4.581  BDRate: -4.358

      Bug fix in super_block_uvrd(). · b910c0bd
      Yushin Cho authored
      In super_block_uvrd(),if is_cost_valid == 0, all return parameters,
      i.e. rate, distortion, skippable, and sse, are reset.
      So, should not call txfm_rd_in_plane() if is_cost_valid == 0.
      Also, the bug causes av1_xform_quant() to see invalid diff signal
      since av1_subtract_plane() is not called in super_block_uvrd().
