      Fixed handling of regularly placed keyframes · 086ae992
      Adrian Grange authored
      The encoder was not handling requests to place keyframes at
      fixed intervals, i.e. kf_min_dist == kf_max_dist, correctly.
      
      In this case when looking to place the next keyframe it was
      accumulating stats all the way up to the end of the firstpass
      file. This patch corrects this behavior.

      Change naming of end_usage parameter. · 4c7af859
      Paul Wilkins authored
      The end_useage parameter  is confusingly named since it
      now actually defines the rate control method used.

      add a context tree structure to encoder · e890c257
      Jim Bankoski authored
      This patch sets up a quad_tree structure (pc_tree) for holding all of
      pick_mode_context data we use at any square block size during encoding
      or picking modes.  That includes contexts for 2 horizontal and 2 vertical
      splits, one none, and pointers to 4 sub pc_tree nodes corresponding
      to split.  It also includes a pointer to the current chosen partitioning.
      
      This replaces code that held an index for every level in the pick
      modes array including:  sb_index, mb_index,
      b_index, ab_index.
      
      These were used as stateful indexes that pointed to the current pick mode
      contexts you had at each level stored in the following arrays
      
      array ab4x4_context[][][],
      sb8x4_context[][][], sb4x8_context[][][], sb8x8_context[][][],
      sb8x16_context[][][], sb16x8_context[][][], mb_context[][], sb32x16[][],
      sb16x32[],  sb32_context[], sb32x64_context[], sb64x32_context[],
      sb64_context
      
      and the partitioning that had been stored in the following:
      b_partitioning, mb_partitioning, sb_partitioning, and sb64_partitioning.
      
      Prior to this patch before doing an encode you had to set the appropriate
      index for your block size ( switch statement),  update it ( up to 3
      lookups for the index array value) and then make your call into a recursive
      function at which point you'd have to call get_context which then
      had to do a switch statement based on the blocksize,  and then up to 3
      lookups based upon the block size to find the context to use.
      
      With the new code the context for the block size is passed around directly
      avoiding the extraneous switch statements and multi dimensional array
      look ups that were listed above.   At any level in the search all of the
      contexts are local to the pc_tree you are working on (in?).
      
      In addition in most places code that used to call sub functions and
      then check if the block size was 4x4 and index was > 0 and return
      now don't preferring instead to call the right none function on the inside.

      Add experimental VBR adaptation method. · 085f76e5
      Paul Wilkins authored
      Add code to monitor over and under spend and
      apply limited correction to the data rate of subsequent
      frames. To prevent the problem of starvation or overspend
      on individual frames (especially near the end of a clip) the
      maximum adjustment on a single frame is limited to a %
      of its un-modified allocation.

      Refactoring motion search libs · b80020d4
      Deb Mukherjee authored
      The core motion estimation fucntions all return sad now consistently.
      The only exception is vp9_full_pixel_diamond(), however the core diamond
      and refining search routines called from vp9_full_pixel_diamond() also
      return SAD. If variance of pred error + mv cost is desired it must be
      calculated explicitly outside these functions. For very fast encoding,
      hopefully this will eliminate some redundant computations.
      
      Also suggests reimplementing FAST_HEX with the vp9_pattern_search
      framework. It is not exactly the same as the existing FAST_HEX, but
      performance is slightly better and speed is very similar. Enables
      removing a lot of duplicate code.
