      Migrate quantization functions from vp9/ to vpx_dsp/ · 38f1fbbb
      Yunqing Wang authored
      The following quantization functions were moved:
      vp9_quantize_b
      vp9_quantize_b_32x32
      vp9_highbd_quantize_b
      vp9_highbd_quantize_b_32x32
      
      vp9_quantize_dc
      vp9_quantize_dc_32x32
      vp9_highbd_quantize_dc
      vp9_highbd_quantize_dc_32x32
      
      The purpose of doing that was to allow these functions to be shared
      by multiple codecs.

      Move shared SAD code to vpx_dsp · d5d92898
      Johann authored
      Create a new component, vpx_dsp, for code that can be shared
      between codecs. Move the SAD code into the component.
      
      This reduces the size of vpxenc/dec by 36k on x86_64 builds.

      Add skin detection. · 56435bb7
      Marco authored
      Simple skin detection, from vp8; works reasonable on most of the
      RTC clips, but could miss sometimes.
      
      Added debug flag to write out skin map over source input.

      vp9_ethread: the tile-based multi-threaded encoder · eba9c762
      Yunqing Wang authored
      Currently, VP9 supports column-tile encoding, which allows a frame
      to be encoded in multiple column tiles independently. The number of
      column tiles are set by encoder option "--tile-columns". This
      provides a way to encode a frame in parallel.
      
      Based on previous set of patches, this patch implemented the tile-
      based multi-threaded encoder. Each thread processes one or more
      tiles.
      
      Usage:
      For HD clips:
      --tile-columns=2 --threads=1/2/3/4
      
      While using 4 threads, tests showed that the encoder achieved
      2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at
      realtime speed 5.

      Refactored idct routines and headers · 3a8c43a4
      Peter de Rivaz authored
      This change is made in preparation for a
      subsequent patch which adds acceleration
      for the highbitdepth transform functions.
      
      The highbitdepth transform functions attempt
      to use 16/32bit sse instructions where possible,
      but fallback to using the C implementations if
      potential overflow is detected.  For this reason
      the dct routines are made global so they can be
      called from the acceleration functions in the
      subsequent patch.

      All sad function that process above 32 consecutive elements are optimized

      The functions that appeared as a hotspot is vp9_sad32x32 and vp9_sad64x64
      vp9_sad32x32 was optimized by 68% and vp9_sad64x64 was optimized by 90%
      both of them gave and overall ~2.3% user level gain
