      Correct 3 step search site initialziation · 838eae39
      Yaowu Xu authored
      39c7b01d accidently reverted the row/col initialization, which broke
      mv clamps, which is dependent on the sites for valid motion vector
      range. This commit fixed the issue.

      Enable per transformed block zero coeffs forcing · a517343c
      Jingning Han authored
      This commit enables forcing all coefficients zero per transformed
      block, when its rate-distortion cost is lower than regular coeff
      The overall performance improvement (including its parent patch on
      calculating rd cost per transformed block) at speed 1:
      derf:  0.298%
      yt:    0.452%
      hd:    0.741%
      stdhd: 0.006%

      Improves constant qual, constrained qual turned on · d11221f4
      Deb Mukherjee authored
      Adds modeled functions to decide the qp for altref frames in constant q
      mode similar to other functions in use in bitrate mode.
      Also turns on the constrained quality mode (end-usage=2) option which
      was turned off before. Basic testing shows the mode works in principle,
      to cap bitrate to the target-bitrate specified, while allowing lower
      bitrate depending on the cq-level specified. The mode will need to be
      improved over time.
      Results for constant quality vs bitrate control mode:
      derfraw300/fullderfraw: +3.0% at constant quality over bitrate control.
      fullstdhdraw: +4.341%
      stdhdraw250: +5.361%

      Calculate rd cost per transformed block · 78fbb106
      Jingning Han authored
      This commit makes the rate-distortion optimization loop evaluate
      the rd costs of regular quantization and all zero coeffs, per
      transformed block. It improves speed 1 compression performance:
      derf: 0.245%
      yt:   0.515%
      For a large partition that consists multiple transformed blocks,
      this allows more flexibility to selectively force a portion of
      them coded as all zero coeffs, as well be continued in the next

      Remove redundant mv_pred use for sub8x8 blocks · 44b708b4
      Jingning Han authored
      The sub8x8 blocks has its own motion vector reference scheme. The
      mv_pred is only used blocks of sizes 8x8 and above, to find the
      starting point for motion search.
      This change does not change any coding behavior. It makes the
      encoding process slightly faster. (0.5% speed-up for local test on
      speed 1.)

      Fix x86inc.asm to build PIC code correctly · 9d901217
      Yunqing Wang authored
      Current x86inc.asm didn't handle 32bit PIC build properly.
      TEXTRELs were seen in the library built. The PIC macros from
      libvpx's x86_abi_support.asm was used to fix this problem.
      The assembly code was modified to use the macros.
      Notes: We need this fix in for decoder building. Functions in
      encoder will be fixed later.

      search on the largest partition is already done. This is to fix
      a crash at speed 1/2 encoder where an invalid mv is used in mv

      Adaptive motion search control · c4826c59
      Jingning Han authored
      This commit enables adaptive constraint on motion search range for
      smaller partitions, given the motion vectors of collocated larger
      partition as a candidate initial search point.
      It makes speed 0 runtime of bus at CIF and 2000 kbps goes from
      167s down to 162s (3% speed-up), at 0.01dB performance gains. In
      the settings of speed 1, this makes the runtime goes from 33687 ms
      to 32142 ms (4.5% speed-up), at 0.03dB performance gains.
      Compression performance wise, it gains at speed 1:
      derf  0.118%
      yt    0.237%
      hd    0.203%
      stdhd 0.438%
