      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.

      Fix potential overflow issue in SSSE3 forward 8x8 2D-DCT · 540d9103
      Jingning Han authored
      The SSSE3 implementation might find a potential overflow issue in
      its second 1-D transform, if all input residual pixels are close to
      255. This commit fixes the issue and re-enables the unit test on
      the SSSE3 version.

      Fix AQ mode 2 bug where delta causes Q 0. · 090d0798
      Paul Wilkins authored
      In Aq mode 2 for kf/arf/gf the segment q delta
      is calculated and then applied by re-quantization without
      going through the rd loop again. If the base Q != 0
      but the segment Q == 0 (lossless) this can could give rise
      to a situation where we have an illegal combination of
      transform size and Q. (Q == 0 requires that all blocks
      are coded 4x4 WHT).

      Fix a problem of using an uninitialized parameter · 538af7db
      Yaowu Xu authored
      This commit added a call to set speed feature before initializing
      motion search, fixed the problem where unintialized search method
      is used before its value being set.
