      Fix bug with chroma-sub8x8 + resizing · 11132ce3
      David Barker authored
      The special path in build_inter_predictors for chroma blocks
      corresponding to sub8x8 luma blocks would always fetch the
      scale factors from 'xd', which correspond (at least in the
      decoder) to the references of the block for which is_chroma_reference
      returns true.
      
      The correct behaviour is to fetch the scale factors from 'ref_buf',
      which corresponds to the references of the block currently being
      predicted.
      
      This patch fixes some encode/decode mismatches which were caused
      by the above behaviour when the various reference frames had
      different sizes.

      - First pass encoding time reduces ~10.9% on i7-6700
        at 100 frames, 1080p.
      - avx2 works for coeff number >= 8 cases; coeff number < 8
        case will be implemented by sse2.
      - Unit test is added type B/FP/DC.

      Fix daala-dist, rd tx search · 04eb9594
      Yushin Cho authored
      Previously, for block >=8x8, and tx < 8x8,
      we skipped setting the early-exit flag in block_rd_txfm() because
      distortion for sub8x8 tx block is from MSE but reference (best)
      is from daala-dist.
      However, not setting early-exit flag turned out to be the reason
      for a regression in MSE probe mode of daala-dist because
      it loses the chance to set rd_stats properly.
      
      On the other hand, there is still a small regression, say 0.05% psnr bd-rate,
      which seems to occur in the case that a tx block in a partition has chosen
      the skipped rd_cost since it is smaller than non-skip rd_cost and
      set the early-exit flag to 0 (so, not exit), but the daala-dist applied
      to the whole partition cannot access the same info but can choose from
      two kinds of rd_costs:
      1) all tx blocks are skipped (even if a tx block has non-zero coeff) and 0 bits
      2) sum of final distortion of all tx blocks (i.e. non-zero coeff decoded)
      and bits to encode coeffs.
