      Add encoder support for frame_refs_signaling · 6b172bba
      Zoe Liu authored
      Currently set cm->frame_refs_short_signaling as 0 by default. It will
      write the one extra bit to the frame header, and leave all the encoder
      setup the same as the baseline. It is in the TODO list for the encoder
      side implementation for cm->frame_refs_short_signaling == 1.

      Don't read chroma delta_lflevels in mono mode · f74b4abd
      Imdad Sardharwalla authored
      There are 4 delta_lflevels (FRAME_LF_COUNT=4), corresponding to 2 for the luma
      plane and 1 for each of the U and V planes. In monochrome mode we do not need
      to use/encode/decode the last two values, and so in this case the for loops all
      terminate at FRAME_LF_COUNT - 2 rather than FRAME_LF_COUNT.

      Clean up and use do_post_rounding consistently · c3a8ae46
      Debargha Mukherjee authored
      This patch simplifies the setting and use of the do_post_rounding
      flag consistently across all convolve/warp operations. It is always
      set now to 1 for compound modes, but the masked blending operation
      can subsequently turn it off.
      To accomplish this, for the warped case, the use of the conv_params->dst
      buffer is made consistent with the other non-warp convolves,
      in the sense that it is used only when is_compound is 1.

      [NORMATIVE] Add decoder support for frame_refs_signaling · b57fee02
      Zoe Liu authored
      One bit is added to the frame header, to signal whether the references
      for inter frames will be short-signaled.
      
      When the bit is set, only 6 bits are used at the frame header level to
      signal the choices of LAST_FRAME and GOLDEN_FRAME out of the eight
      buffered references. All the other 5 references will be specified
      using the frame offset info. Hence, compared to the baseline, the use
      of frame_refs_signaling provides 2 scenarios:
      
      (1) Reference short-signaling:
          3*7 - (1+3*2) = 14 bits are saved in the frame header;
      (2) Reference regular-signaling:
          1 bit is added to the frame header.
