      Move qcoeff, dqcoeff from BLOCKD to per-plane data · 4c05a051
      John Koleszar authored
      Start grouping data per-plane, as part of refactoring to support
      additional planes, and chroma planes with other-than 4:2:0
      subsampling.

      Fixing bug introduced by previous commit. · f857e074
      Dmitry Kovalev authored
      Inside decode_sb_4x4 it should be
      "get_tx_type_4x4(mb, y_idx * y_size + x_idx)"
      but it was
      "get_tx_type_4x4(mb, y_idx * (2 * y_size) + x_idx)".
      Also making code of decode_sb_4x4, decode_sb_8x8, and decode_sb_16x16
      formatted in the same way.

      Fixed incorrect use of compute_qdelta() · 9b9136f8
      Paul Wilkins authored
      This function expects real Q values as inputs
      not index values.
      
      The use-age her impacts the Q chosen for force key
      frames. Though this is a bug fix I have not yet verified
      whether following the bug fix the q multiplier value used is
      correct.

      Remove special case vp9_decode_coefs_4x4 · 1e5f25ec
      John Koleszar authored
      This code was only called in the BPRED case, but had no real special
      case associated with it. Made BPRED behave like all other modes. No
      bitstream change.

      Modify vp9_setup_interp_filters function · 4ca882f3
      Yunqing Wang authored
      Took vp9_setup_scale_factors_for_frame() out from
      vp9_setup_interp_filters(), so that it is only called once per
      frame instead of per macroblock. Decoder tests showed a 1.5%
      performance gain.

      Calculate SSIM over both reconstruction as well as postproc buffer. · 6dd6ffb0
      Ronald S. Bultje authored
      We used to calculate SSIM only over the postproc buffer, whereas we
      calculate PSNR for both. Compared to postproc-SSIM, this is about 0.3%
      higher for derf, 1.4% lower for hd and 0.5% lower for stdhd, although
      it is highly variable on a per-clip basis.

      Framework changes in nzc to allow more flexibility · fe9b5143
      Deb Mukherjee authored
      The patch adds the flexibility to use standard EOB based coding
      on smaller block sizes and nzc based coding on larger blocksizes.
      The tx-sizes that use nzc based coding and those that use EOB based
      coding are controlled by a function get_nzc_used().
      By default, this function uses nzc based coding for 16x16 and 32x32
      transform blocks, which seem to bridge the performance gap
      substantially.
      
      All sets are now lower by 0.5% to 0.7%, as opposed to ~1.8% before.

      Adjust mv_ratio_accumulator threshold. · 17ef6a8d
      Paul Wilkins authored
      This threshold effectively limits the amount of motion
      from one end of a GF/ARF group to the other.
      This patch makes the threshold depend on image size.
