      In frame Q adjustment experiment. · 644bd87e
      Paul Wilkins authored
      The idea here is to allow "in frame" adjustment of the final Q
      value used to encode each SB64, using segmentation.
      There is also adjustment of the rd mult in regions of overspend.
      Activated using aq_mode=2

      Move WebM writing support out of vpxenc.c. · 03848f5c
      Tom Finegan authored
      This is mainly a clean up patchset. It moves the WebM writing support
      out of vpxenc and into its own source file. Changes to tools_common and
      vpxdec result from relocation of shared bits of code.

      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.

      Make "good" quality 2-pass vpxenc encoding default · 0d8723f8
      Deb Mukherjee authored
      Currently, the best quality mode in VP9 is not very well developed,
      and unnecessarily makes the encode too slow. Hence the command line
      default is changed to "good" quality. Also, the number of passes
      default is changed to 2 passes as well, since 1-pass encoding is
      not very efficient in VP9.
      Besides, a number of VP9 defaults are set to the currently
      recommended settings. With these changes, vpxenc
      run with --codec=vp9 --kf-max-dist=9999 --cpu-used=0 should
      work about the same as our borg results.
      Note when the --cpu-used=0 option is dropped there will be a slight
      difference in the output, because of a difference in the cpu-used
      value for the first pass. Specifically, the default when unspecified
      is to use cpu_used=1 for the first pass and cpu_used=0 for the
      second pass. But when specified, both passes will use the cpu-used
      value specified.
      Note that this also changes the default for VP8 as being "good"
      but other options stay unchanged.

      Y4M input support for 4:2:2, 4:4:4, 4:4:4:4 · 8dd8287e
      John Koleszar authored
      Adds a new experiment CONFIG_NON420 that allows other chroma subsamplings
      to be passed to the codec. This commit allows the data to be passed from
      a y4m input file through vpxenc to the codec, where they're currently
      rejected. Later commits will finish support for this inside the codec.

      Clamp inferred motion vectors only · 12bf0796
      Jingning Han authored
      Clamp only the motion vectors inferred from neighboring reference
      macroblocks. The motion vectors obtained through motion search in
      NEWMV mode are constrained during the search process, which allows
      a relatively larger referencing region than the inferred mvs.
      Hence further clamping the best mv provided by the motion search may
      affect the efficacy of NEWMV mode.
      Synchronized the decoding process. The decoded mvs in NEWMV modes
      should be guaranteed to fit in the effective range. Put a mv range
      clamping function there for security purpose.
      This improves the coding performance of high motion sequences, e.g.,
      derf set:
      foreman 0.233%
      husky   0.175%
      icd     0.135%
      mother_daughter 0.337%
      pamphlet        0.561%
      stdhd set:
      blue_sky 0.408%
      city     0.455%
      also saw sunflower goes down by -0.469%.

      Implicit weighted prediction experiment · 23144d23
      Deb Mukherjee authored
      Adds an experiment to use a weighted prediction of two INTER
      predictors, where the weight is one of (1/4, 3/4), (3/8, 5/8),
      (1/2, 1/2), (5/8, 3/8) or (3/4, 1/4), and is chosen implicitly
      based on consistency of the predictors to the already
      reconstructed pixels to the top and left of the current macroblock
      or superblock.
      Currently the weighting is not applied to SPLITMV modes, which
      default to the usual (1/2, 1/2) weighting. However the code is in
      place controlled by a macro. The same weighting is used for Y and
      UV components, where the weight is derived from analyzing the Y
      component only.
      Results (over compound inter-intra experiment)
      derf: +0.18%
      yt: +0.34%
      hd: +0.49%
      stdhd: +0.23%
      The experiment suggests bigger benefit for explicitly signaled weights.

      Add VP9_GET_REFERENCE control · b3c350a1
      John Koleszar authored
      This is like VP8_COPY_REFERENCE, but returns a pointer to the reference
      frame rather than a copy of it. This is useful when the application
      doesn't know what the size of the reference is, as is the case when
      scaling is in effect.
