      Start adaptive threshold for each mode at max. · 689957e3
      Paul Wilkins authored
      Each frame we reset all adaptive thresholds to MAX
      rather than base. As modes are picked their thresholds
      drop down.

      Change meaning of cpi->sf.first_step and rename. · e606cac0
      Paul Wilkins authored
      Renamed cpi->sf.first_step to cpi->sf.reduce_first_step_size
      and changed its meaning such that it is a delta applied to
      reduce the default first step size (>> x) in the motion search
      rather than an absolute value.
      The default first step size is already changed according to the image
      dimensions (smaller for smaller images). cpi->sf.reduce_first_step_size
      now applies a further correction from the default.

      Remove vp9_intra4x4_predict(). Use the common intra prediction
      function for all block sizes.

      Only do metrics on cropped (visible) area of picture. · 450c7b57
      Ronald S. Bultje authored
      The part where we align it by 8 or 16 is an implementation detail that
      shouldn't matter to the outside world.

      Add averaging-SAD functions for 8-point comp-inter motion search. · c24d9223
      Ronald S. Bultje authored
      Makes first 50 frames of bus @ 1500kbps encode from 3min22.7 to 3min18.2,
      i.e. 2.3% faster. In addition, use the sub_pixel_avg functions to calc
      the variance of the averaging predictor. This is slightly suboptimal
      because the function is subpixel-position-aware, but it will (at least
      for the SSE2 version) not actually use a bilinear filter for a full-pixel
      position, thus leading to approximately the same performance compared to
      if we implemented an actual average-aware full-pixel variance function.
      That gains another 0.3 seconds (i.e. encode time goes to 3min17.4), thus
      leading to a total gain of 2.7%.

      Add 8x8 dct/adst unit tests · ab362621
      Jingning Han authored
      This commit enables 8x8 DCT and hybrid transform unit tests. It
      also tunes the forward hybrid transform rounding opertions for
      more precise round-trip performance.

      Enable sse2 implmentation of 8x8 ADST/DCT · a32a086d
      Jingning Han authored
      This commit makes use of the butterfly structure to enable the sse2
      version implementation of 8x8 ADST/DCT hybrid transform coding.
      The runtime of hybrid transform module goes down from 1170 cycles
      to 245 cycles. Overall speed-up around 1.5%.
