      Fix rectangular partition check in speed 1 · 195061fe
      Jingning Han authored
      Make encoder skip rectangular partition check in speed 1 and above,
      when early termination was triggered in partition split.
      Thanks Guillaume (gmartres@) for catching this issue.
      This change makes bus_cif at 2000kbps speed 1 runtime goes down from
      25612ms to 23438ms (about 9% speed-up), at the expense of -0.235%
      performance down.

      Improved auto_partition_range. · 65b93c7e
      Paul Wilkins authored
      The code now takes into account temporal and spatial
      information to determine the partition size range, but the
      frequency counts have been removed.
      The net effect is similar in quality but about 10% faster.

      Alter Speed 3. · a76caa7f
      Paul Wilkins authored
      This patch deletes the variance based speed three partitioning.
      Speed 3 now uses the same partitioning method as speed 2
      but with some stricter conditions.
      The speed and quality are now somewhere between speeds 2 and 4
      whereas before it was worse in both than speed 4.

      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.)
