      Reuse inter prediction result in real-time speed 6 · 0aae1000
      Yunqing Wang authored
      In real-time speed 6, no partition search is done. The inter
      prediction results got from picking mode can be reused in the
      following encoding process. A speed feature reuse_inter_pred_sby
      is added to only enable the resue in speed 6.
      This patch doesn't change encoding result. RTC set tests showed
      that the encoding speed gain is 2% - 5%.

      Modify non-rd intra mode checking · 55834d42
      Yunqing Wang authored
      Speed 6 uses small tx size, namely 8x8. max_intra_bsize needs to
      be modified accordingly to ensure valid intra mode checking.
      Borg test on RTC set showed an overall PSNR gain of 0.335% in speed
      This also changes speed -5 encoding by allowing DC_PRED checking
      for block32x32. Borg test on RTC set showed a slight PSNR gain of
      0.145%, and no noticeable speed change.

      Separate rate-distortion modeling for DC and AC coefficients · 7c45dc98
      Jingning Han authored
      This is the first step to rework the rate-distortion modeling used
      in rtc coding mode. The overall goal is to make the modeling
      customized for the statistics encountered in the rtc coding.
      This commit makes encoder to perform rate-distortion modeling for
      DC and AC coefficients separately. No speed changes observed.
      The coding performance for pedestrian_area_1080p is largely
      speed -5, from 79558 b/f, 37.871 dB -> 79598 b/f, 38.600 dB
      speed -6, from 79515 b/f, 37.822 dB -> 79544 b/f, 38.130 dB
      Overall performance for rtc set at speed -6 is improved by 0.67%.

      skip the un-necessary motion search in the first pass · cdc954fd
      Pengchong Jin authored
      This patch allows the VP9 encoder to skip the un-necessary
      motion search in the first pass. It computes the motion error
      of 0,0 motion using the last source frame as the reference,
      and skips the further motion search if this error is small.
      Borg test shows overall the patch gives PSNR gain (derf -0.001%,
      yt 0.341%, hd 0.282%). Individual clips may have PSNR gain or
      loss. The best PSNR performance is 7.347% and the worst is -0.662%.
      The first pass encoding speedup for slideshow clips is over 30%.

      Fast computation path for forward transform and quantization · ccba289f
      Jingning Han authored
      This commit enables a fast path computational flow for forward
      transformation. It checks the sse and variance of prediction
      residuals and decides if the quantized coefficients are all
      zero, dc only, or more. It then selects the corresponding coding
      path in the forward transformation and quantization stage.
      It is currently enabled in rtc coding mode. Will do it for rd
      coding mode next.
      In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps
      goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up.
      Overall coding performance for rtc set is changed by -0.18%.

      skip un-neccessary motion search in the first pass · 5daef90e
      Pengchong Jin authored
      This patch allows the encoder to skip the
      un-neccessary motion search in the first pass. It
      calculates the error of the zero motion vector using
      the last source frame as reference and skips the
      further motion search in the first pass if the error
      is small.
      The encoding speedup of the first pass for slideshow
      videos is over 30%. Borg test shows the overall PSNR
      performance remain approximately the same (derf -0.009,
      hd 0.387, yt 0.021, stdhd 0.065). Individual clips may
      have either PSNR gain or loss. The worst PSNR perfomance
      is from yt set, with a PSNR loss of -1.1.

      Use small transform size in non-rd real-time mode · b04d7668
      Yunqing Wang authored
      In non-rd real-time mode, choosing smaller transform size in
      encoding gives better video quality and good speed gain than
      choosing larger transform size. This patch set tx size search
      method to ALLOW_8X8, which is better than using 4x4 or other
      larger sizes.
      Borg tests on rtc set at speed 6 showed significant gain on quality.
      PSNR gain: 11.034% and SSIM gain: 15.466%.
      The speed gain is 5% - 12% for <720p clips, and 2% - 7% for
      720p clips.
