      Alternate reference frame · 140182b9
      Jingning Han authored
      This commit re-designs the alternate reference frame generation
      process. It employs non-local mean approach to produce more stable
      pixel estimation for alternate reference frame. It improves the
      compression performance gains:
      derf   0.5%
      hevcmr 0.8%
      stdhd  1.3%
      hevchr 1.0%
      
      The encoding time at speed 0 is not affected.

      With the sad functions, and hopefully the variance functions soon,
      moving to the vpx_dsp location, place the defines used in the
      reference C code in a common location.

      replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNED · fd3658b0
      James Zern authored
      this macro was used inconsistently and only differs in behavior from
      DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
      is used with calls to assembly, while generic c-code doesn't rely on it,
      so in a c-only build without an alignment attribute the code will
      function as expected.

      For the test clip used, the decoder performance improved by ~2%.
      This is also an intermediate step towards adding back the
      mode_info streams.

      Frank Galligan authored
      Add support for setting byte alignment on the Y, U, and V plane of the
      reference buffers. The byte alignment must be a power of 2, from 32 to
      1024. A value of 0 sets legacy alignment.

      vp9_ethread: modify VP9_COMP structure · edbd61e1
      Yunqing Wang authored
      This patch modified struct VP9_COMP. Created a struct ThreadData
      to include data that need to be copied for each thread. In
      multiple thread case, one thread processes one tile. all threads
      share one copy of VP9_COMP,
      (refer to VP9_COMP *cpi in the code)
      but each thread has its own copy of ThreadData,
      (refer to ThreadData *td in the code).
      Therefore, within the scope of encode_tiles(), both cpi and td
      need to be passed as function parameters.
      
      In single thread case, the FRAME_COUNTS pointer in ThreadData
      points to "counts" in VP9_COMMON.

      [spatial svc]Another workaround to avoid using prev_mi · c113457a
      Minghai Shang authored
      We encode a empty invisible frame in front of the base layer frame to
      avoid using prev_mi. Since there's a restriction for reference frame
      scaling factor, we have to make it smaller and smaller gradually until
      its size is 16x16.

      Subpel search cleanups and enhancements · d78dbff0
      Deb Mukherjee authored
      - Some fixes to surface fit.
      - Returns variance function as cost rather than sad in the
        pattern search and diamond search functions. Only
        vp9_pattern_search_sad function used in bigdia search
        uses sad as integer 1-away costs.
      - Deploys SUBPEL_TREE_PRUNED_MORE for speed 4+.
      
      Results:
      derf [Speed 3]: About +0.036% in coding efficiency without any
      discernible speed loss.
      derf [Speed 4]: About 2-3% faster at -0.199% loss in coding efficiency.
      derf [Speed 5]: About 3-4% faster at -0.149% loss in coding efficiency.

      Remove mi_grid_* structures. · c70cea97
      hkuang authored
      mi_grid_* are arrays of pointer to pointer. They save the pointers that point
      to the MIs in cm->mi. But they are unnecessary and complicated. The original
      goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
      inside MODE_INFO_t, same goal could be achieved.
      
      This commit totally removes the mi_grid_* structures. But there are still
      many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
      will do on-demand MODE_INFO_t allocation in order to save these memories.
