      Tx size selection enhancements · 8d3d2b76
      Deb Mukherjee authored
      (1) Refines the modeling function and uses that to add some speed
      features. Specifically, intead of using a flag use_largest_txfm as
      a speed feature, an enum tx_size_search_method is used, of which
      two of the types are USE_FULL_RD and USE_LARGESTALL. Two other
      new types are added:
      USE_LARGESTINTRA (use largest only for intra)
      USE_LARGESTINTRA_MODELINTER (use largest for intra, and model for
      inter)
      
      (2) Another change is that the framework for deciding transform type
      is simplified to use a heuristic count based method rather than
      an rd based method using txfm_cache. In practice the new method
      is found to work just as well - with derf only -0.01 down.
      The new method is more compatible with the new framework where
      certain rd costs are based on full rd and certain others are
      based on modeled rd or are not computed. In this patch the existing
      rd based method is still kept for use in the USE_FULL_RD mode.
      In the other modes, the count based method is used.
      However the recommendation is to remove it eventually since the
      benefit is limited, and will remove a lot of complications in
      the code
      
      (3) Finally a bug is fixed with the existing use_largest_txfm speed feature
      that causes mismatches when the lossless mode and 4x4 WH transform is
      forced.
      
      Results on derf:
      USE_FULL_RD: +0.03% (due to change in the tables), 0% encode time reduction
      USE_LARGESTINTRA: -0.21%, 15% encode time reduction (this one is a
      pretty good compromise)
      USE_LARGESTINTRA_MODELINTER: -0.98%, 22% encode time reduction
      (currently the benefit of modeling is limited for txfm size selection,
      but keeping this enum as a placeholder) .
      USE_LARGESTALL: -1.05%, 27% encode-time reduction (same as existing
      use_largest_txfm speed feature).

      Add speed feature to disable splitmv · b12e060b
      Yunqing Wang authored
      Added a speed feature in speed 1 to disable splitmv for HD (>=720)
      clips. Test result on stdhd set: 0.3% psnr loss and 0.07% ssim
      loss. Encoding speedup is 36%.
      
      (For reference: The test result on derf set showed 2% psnr loss
      and 1.6% ssim loss. Encoding speedup is 34%. SPLITMV should be
      enabled for small resolution videos.)

      Calculate rd cost per transformed block · b91a1586
      Jingning Han authored
      Compute the rate-distortion cost per transformed block, and cumulate
      the cost through all blocks inside a partition. This allows encoder
      to detect if the cumulative rd cost is already above the best rd cost,
      thereby enabling early termination in the rate-distortion optimization
      search.

      Make get_coef_context() branchless. · 26b6318d
      Ronald S. Bultje authored
      This should significantly speedup cost_coeffs(). Basically what the
      patch does is to make the neighbour arrays padded by one item to
      prevent an eob check in get_coef_context(), then it populates each
      col/row scan and left/top edge coefficient with two times the same
      neighbour - this prevents a single/double context branch in
      get_coef_context(). Lastly, it populates neighbour arrays in pixel
      order (rather than scan order), so we don't have to dereference the
      scantable to get the correct neighbours.

      Make coefficient skip condition an explicit RD choice. · af660715
      Ronald S. Bultje authored
      This commit replaces zrun_zbin_boost, a method of biasing non-zero
      coefficients following runs of zero-coefficients to be rounded towards
      zero, with an explicit skip-block choice in the RD loop.
      
      The logic is basically that if individual coefficients should be rounded
      towards zero (from a RD point of view), the trellis/optimize loop should
      take care of it. If whole blocks should be zero (from a RD point of
      view), a single RD check is much more efficient than a complete
      serialization of the quantization loop.
      
      Quality change: derf +0.5% psnr, +1.6% ssim; yt +0.6% psnr, +1.1% ssim.
      SIMD for quantize will follow in a separate patch. Results for other
      test sets pending.
