      Removed bmi copy to/from BLOCKD · b870947d
      Scott LaVarnway authored
      for SPLITMV and B_PRED modes.  Modified code to use the bmi
      found in mode_info_context instead of BLOCKD.  On the decode
      side, the uvmvs are calculated only when required, instead of
      every macroblock.  This is WIP. (bmi should eventually be
      removed from BLOCKD)
      Small performance gains noticed for RT encodes and decodes.(VGA)

      Fix data accesses for simple loopfilters · 85358d04
      Johann authored
      The data that the simple horizontal loopfilter reads is aligned, treat
      it accordingly.
      
      For the vertical, we only use the bottom 4 bytes, so don't read in 16
      (and incur the penalty for unaligned access).
      
      This shows a small improvement on older processors which have a
      significant penalty for unaligned reads.
      
      postproc_mmx.c is unused

      Copy less when active map is in use · 4e8d35a4
      Alpha Lam authored
      When active map is specified and the current frame is not a key frame,
      golden frame nor a altref frame then copy only those active regions.
      
      This significantly reduces encoding time by as much as 19% on the test
      system where realtime encoding is used. This is particularly useful
      when the frame size is large (e.g. 2560x1600) and there's only a few
      action macroblocks.

      Instead of a single mid GF boost apply a few extra bits to

      and a subsequent iteration of the recode loop disables resampling,

      Adjust half-pixel only search · b9f19f89
      Yunqing Wang authored
      Changed motion search in vp8_find_best_half_pixel_step() to be the
      same as in vp8_find_best_sub_pixel_step(), which checks 5 points
      instead of 8 points. This only affects real-time mode with
      cpu-used >=9. Tests showed it gives 2% encoding speedup with
      a quality loss(psnr) of up to 0.5%.

      Convert rc_max_intra_bitrate_pct to control · 1654ae9a
      John Koleszar authored
      Since this is the only ABI incompatible change since the last release,
      convert it to use the control interface instead. The member of the
      configuration struct is replaced with the VP8E_SET_MAX_INTRA_BITRATE_PCT
      control.
      
      More significant API changes were expected to be forthcoming when this
      control was first introduced, and while they continue to be expected,
      it's not worth breaking compatibility for only this change.

      _pixel_step() functions which are called when speed >= 5. Test
      result (using tulip clip):
      
      1. On Core2 Quad machine(Linux)
      rt mode, speed (-5 ~ -8), encoding speed gain: 2% ~ 3%
      rt mode, speed (-9 ~ -11), encoding speed gain: 1% ~ 2%
      rt mode, speed (-12 ~ -14), no noticeable encoding speed gain
      
      2. On Xeon machine(Linux)
      Test on speed (-5 ~ -14) didn't show noticeable speed change.
