      8x8/16x16 HT types V_DCT to H_FLIPADST SSE2 optimization · 770bf715
      Yi Luo authored
      - Wrote function: fidtx8_sse2() and fidtx16_sse2().
      - Turned on vp10_fht8x8_sse2()/vp10_fht16x16_sse2() for new types.
      - Updated 8x8/16x16 unit tests for accuracy/speed.
      - Running 20K times with random numbers and getting through
        tx type from V_DCT to H_FLIPADST, SSE2 speed improvement:
        8x8: ~131%
        16x16: ~66%

      vp9: 1 pass vbr mode at speed 5: switch to use mv.search to NSTEP. · f94124cf
      Marco authored
      Change only affects 1 pass, vbr, speed = 5 (real-time mode).
      Some improvement for high motion content.
      AvgPSNR/SSIM metrics for ytlive set all up, on average ~2%,
      some clips (high motion ones) up 4/5%.
      Encoder speed down: on mynintendo_x1.1280_720.y4m: 47fps -> 44fps.

      A major speed up for obmc experiment · e63792e5
      Yue Chen authored
      Skip checking obmc when regular inter predictor is not so good (the
      rd-cost for Y residual is greater than the total rd of the best mode
      so far.)
      Performance change compared to full rd search:
        +0.006% lowres, -0.056% midres
      Encoding time :
        1.14X baseline (was 1.42X)

      Recover tile coding performance · bdcc1405
      Yunqing Wang authored
      After porting tile coding from VP9 to VP10, some performance
      degradation was seen because of the difference between VP9 and
      Vp10 baseline. This patch disabled some features in VP10 while
      tile coding is turned on. Also, an encoder control API was added
      back for this use case.

      Speed up ext-intra · c85a6812
      hui su authored
      Skip filtered intra modes search in inter frame when DC mode is
      worse than the best mode so far.
      With ext-intra enabled, the overall speed is increased by 20~40%;
      performance drop is 0.03% on lowres and 0.05% on midres.
