      Decide the partitioning threshold from the variance histogram · 9d41313e
      Yunqing Wang authored
      Before encoding a frame, calculate and store each 16x16 block's
      variance of source difference between last and current frame.
      Find partitioning threshold T for the frame from its variance
      histogram, and then use T to make partition decisions.
      
      Comparing with fixed 16x16 partitioning, rtc set test showed an
      overall psnr gain of 3.242%, and ssim gain of 3.751%. The best
      psnr gain is 8.653%.
      
      The overall encoding speed didn't change much. It got faster for
      some clips(for example, 12% speedup for vidyo1), and a little
      slower for others.
      
      Also, a minor modification was made in datarate unit test.

      Skip the partition search for the frame with no motion · 12861260
      Pengchong Jin authored
      This patch allows the encoder to skip the partition search for the
      frame if it is an inter frame and only zero motion vectors have
      been detected in the first pass. The partition size is directly
      assigned according to the difference variance.
      
      Borg tests show overall little performance changes in term of PSNR
      (derf -0.027%, yt 0.152%, hd 0.078%, stdhd 0%). The worst case of
      PSNR loss is -0.514% from yt. The best PSNR gain is 4.293% from yt.
      The second pass encoding speedup for slideshow clips is 15%-40%.

      Experiment for mid group second arf. · 2e430cba
      Paul Wilkins authored
      This patch implements a mechanism for inserting a second
      arf at the mid position of arf groups.
      
      It is currently disabled by default using the flag multi_arf_enabled.
      
      Results are currently down somewhat in initial testing if
      multi-arf is enabled. Most of the loss is attributable to the
      fact that code to preserve the previous golden frame
      (in the arf buffer) in cases where we are coding an overlay
      frame, is currently disabled in the multi-arf case.

      Add static-threshold skipping in non-rd mode · b91b146d
      Yunqing Wang authored
      Added a skipping test in non-rd inter-mode. After interpolation
      prediction step, the residuals are tested to see if they will be
      quantized to 0 based on modeling between spatial domain and
      frequency domain.
      
      Set static-thresh to 800 for >=720p and 300 for <720p, rtc set
      tests showed
      1. Speed 5, psnr: -0.514%; ssim: -1.748%;
         speedup on related clips: 5% -11%
      2. Speed 6, psbr: -0.628%; ssim: -1.637%;
         speedup on related clips: 4% - 9%

      Force ARNR filtering to be centered on the ARF frame · 59e733ca
      Adrian Grange authored
      ARNR filtering is now forced to be centered on the ARF
      frame and the other two options have been removed.
      
      The other modes of constructing the ARNR frame were
      not used and there does not seem to be any good
      reason to maintain them.
      
      This is purely an encoder-side change.

      Enable vpxenc to specify internal coded frame size · f7bd1274
      Adrian Grange authored
      Added command line flags "resize-width" & "resize-height"
      to allow the user to specify the frame size to encode at.
      
      These two flags are ignored if the "resize-allowed" switch
      is not set to 1.
      
      All frames in the clip are then encoded at this size, which
      must be smaller than the raw frame size.
