      Adding API to read/write uncompressed frame header bits. · df037b61
      Dmitry Kovalev authored
      The API is not final yet and can be changed. Actual layout of
      uncompressed frame part will be finalized later. Right now moving
      clr_type, error_resilient_mode, refresh_frame_context,
      frame_parallel_decoding_mode from first compressed partition to
      uncompressed frame part.

      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).

      WIP: 4x4 idct/recon merge · ba48a111
      Scott LaVarnway authored
      This patch eliminates the intermediate diff buffer usage by
      combining the short idct and the add residual into one function.
      The encoder can use the same code as well.

      Add building blocks for 4x8/8x4 rd search · 8e3d0e4d

      These building blocks enable rate-distortion optimization search
      over block sizes of 8x4 and 4x8. Need to convert them into mmx/sse
      forms.

      New inter mode context. · 6ff3eb16
      Paul Wilkins authored
      This patch creates a new inter mode contest that avoids
      a dependence on the reconstructed motion vectors from
      neighboring blocks. This was a change requested by
      a hardware vendor to improve decode performance.
      
      As part of this change I have also made some modifications
      to stats output code (under a flag) to allow accumulation of
      inter mode context flags over multiple clips
      
      Some further changes will be required to accommodate the
      deprecation of the split mv mode over the next few days.
      
      Performance as stands is around -0.25% on derf and
      std-hd but up on the YT and YT-HD sets. With further tuning
      or some adjustment to the context criteria it should be
      possible to make this change broadly neutral.

      Add joint motion search in comp_inter_inter mode(experiment) · 9f5811c2
      Yunqing Wang authored
      In current code, motion vectors got from single prediction mode are used
      in compound prediction mode directly. These motion vectors may not give
      accurate prediction since they are searched independently. In this patch,
      we took Pascal's suggestion, and did joint motion search in compound
      prediction mode to find better motion vectors in this situation.
      Test results:
      Overall PSNR: 0.570%(derf), 0.918%(stdhd);
      SSIM: 0.572%(derf), 1.009%(stdhd);
      
      The encoder is a little slower. This can be improved since some c
      code is used in motion search.

      Subsampling aware allocs and bitstream · da58436f
      John Koleszar authored
      Make framebuffer allocations according to the chroma subsamping
      factors in use. A bit is placed in the raw part of the frame header for
      each of the two subsampling factors. This will be moved in a future
      commit to make them part of the TBD feature set bits, probably only set
      on keyframes, etc.

      Extension of segmentation to 8 segments. · 31ee193a
      Paul Wilkins authored
      Also some further simplification following removal
      of top node code.
      
      There is an issue in regards to the shared file vp8cx.h
      in regard to the roi_map as this interface assumes that
      there are only 4 segments. I have left the value here as
      4 for now meaning that the roi_map interface is broken
      for VP9.
      
      Note that this change would have been easier if I hadn't
      had to search for hard wire instances of the number 4
      and <= 3.

      Adds an experiment that codes an end-of-orientation symbol
      for every eligible zero encountered in scan order.
      
      This cleans out various other sub-experiments that were part
      of the origiinal patch, which will be later included if found
      useful.
      
      Results are slightly positive on all sets (0.1 - 0.2% range).
