      Change ref frame coding. · 6ef805eb
      Ronald S. Bultje authored
      Code intra/inter, then comp/single, then the ref frame selection.
      Use contextualization for all steps. Don't code two past frames
      in comp pred mode.

      New intra mode and partitioning probabilities. · ad343687
      Ronald S. Bultje authored
      Split partition probabilities between keyframes and non-keyframes,
      since they are fairly different. Also have per-blocksize interframe
      y intramode probabilities, since these vary heavily between different
      blocksizes.
      
      Lastly, replace default probabilities for partitioning and intra modes
      with new ones generated from current codec. Replace counts with actual
      probabilities also.

      Add intra_only and reset_frame_context flags · 9e5bb959
      Adrian Grange authored
      Added two flags to the frame header:
      
      intra_only:
      Signals that the frame is encoded using only INTRA
      coding modes.
      
      reset_frame_context:
      Indicates that the coding context specified
      in the frame header should be reset to default values before the
      frame is encoded/decoded.

      This patch checks at the frame level to see if the previous

      flag check that was done for every mode and removes another
      check that was done prior to every vp9_find_mv_refs().

      Updating the model coef experiment · 39a90bc8
      Deb Mukherjee authored
      Cleans up the experiment. Actually uses reduced counts for backward
      updates, and reduced number of probabilities in the context.
      
      No change in bitstream when the experiment is on.
      
      Between expt on and off:
      derfraw300 is down only -0.062% (which is better than when expts
      were run previously).

      Initial version of alpha channel support · 679e4abd
      John Koleszar authored
      This is a mostly-working implementation of an extra channel in the
      bitstream. Configure with --enable-alpha to test. Notable TODOs:
      
       - Add extra channel to all mismatch tests, PSNR, SSIM, etc
       - Configurable subsampling
       - Variable number of planes (currently always uses all 4)
       - Loop filtering
       - Per-plane lossless quantizer
       - ARNR support
      
      This implementation just uses the same contents as the Y channel
      for the A channel, due to lack of content and general pain in
      playing back 4 channel content. A later patch will use the actual
      alpha channel passed in from outside the codec.

      factors in use. A bit is placed in the raw part of the frame header for

      on keyframes, etc.

      Extend left/above partition context to per mi(8x8) · 4a88ad89
      Jingning Han authored
      Update and buffer left/above partition information context per 8x8
      block. This allows to further enable recursive partition down to
      4x4 block size, and hence deprecating I4X4_PRED and SPLITMV.
      
      This commit also fixes a context buffer swap/restore issue in 32x32
      partition type search. This gives 0.1% performance gain for derf/yt.
      Will refactor the superblock partition type search into recursion
      form.

      Contextual entropy coding of partition syntax · ff2b8aa2
      Jingning Han authored
      This commit enables selecting probability models for recursive block
      partition information syntax, depending on its above/left partition
      information, as well as the current block size. These conditional
      probability models are reasonably stationary and consistent across
      frames, hence the backward adaptive approach is used to maintain and
      update the contextual models.
      
      It achieves coding performance gains (on top of enabling rectangular
      block sizes):
      derf:   0.242%
      yt:     0.391%
      hd:     0.376%
