      Modify encode breakout for static frames · 939791a1
      Yunqing Wang authored
      Thank Paul for the suggestions. While turning on static-thresh
      for static-image videos, a big jump on bitrate was seen. In this
      patch, we detected static frames in the video using first-pass
      stats. For different cases, disable encode breakout or reduce
      encode breakout threshold to limit the skipping.
      More modification need be done to break incorrect partition
      picking pattern for static frames while skipping happens.

      Modified mode skip functionality. · 4f660cc0
      Paul Wilkins authored
      A previous speed feature skipped modes not used in earlier
      partitions but this not longer worked as intended following
      changes to the partition coding order and in conjunction
      with some other speed features (Especially speed 2 and above).
      This modified mode skip feature sets a mask after the first X
      modes have been tested in each partition depending on the
      reference frame of the current best case.
      This patch also makes some changes to the order modes are
      tested to fit better with this skip functionality.
      Initial testing suggests speed and rd hit count improvements
      of up to 20% at speed 1. Quality results. (derf -1.9%, std hd  +0.23%).

      Added extra check to rd_auto_partition_range() · 901c4954
      Paul Wilkins authored
      Added check that the returned max and minimum are
      valid in bottom and right border cases.

      Reduce the amount of extension in src frames · 65c2444e
      Yaowu Xu authored
      The commit changes the border pixel extension from 160 pixel each side
      to what is necessary in arnr filter or motion estimation portion, i.e.
      16 pixel on top and left side. For right or bottom side, the extension
      is changed to either round up image size to multiple of 64 or at least
      16 pixels.

      Fix overflow issue in 16x16 quantization SSSE3 · 09bc942b
      Jingning Han authored
      The 16x16 transform unit test suggested that the peak coefficient
      value can reach 32639. This could cause potential overflow issue
      in the SSSE3 implmentation of 16x16 block quantization. This commit
      fixes this issue by replacing addition with saturated addition.

      Support a constant quality mode in VP9 · e378a89b
      Deb Mukherjee authored
      Adds a new end-usage option for constant quality encoding in vpx. This
      first version implemented for VP9, encodes all regular inter frames
      using the quality specified in the --cq-level= option, while encoding
      all key frames and golden/altref frames at a quality better than that.
      The current performance on derfraw300 is +0.910% up from bitrate control,
      but achieved without multiple recode loops per frame.
      The decision for qp for each altref/golden/key frame will be improved
      in subsequent patches based on better use of stats from the first pass.
      Further, the qp for regular inter frames may also be varied around the
      provided cq-level.

      New mode_info_context storage · dae17734
      Scott LaVarnway authored
      mode_info_context was stored as a grid of MODE_INFO structs.
      The grid now constists of a pointer to a MODE_INFO struct and
      a "in the image" flag.  The MODE_INFO structs are now stored
      as a stream, eliminating unnecessary copies and is a little
      more cache friendly.
      For the test clips used, the decoder performance improved
      by ~4.3% (1080p) and ~9.7% (720p).
      Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
      and 5.9% (720p).
