      Optimization of 8bit block error for high bitdepth · 0134764f
      Geza Lore authored 
      If high bit depth configuration is enabled, but encoding in profile 0,
the code now falls back on optimized SSE2 assembler to compute the
block errors, similar to when high bit depth is not enabled.

      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.
