      Enable background detection for adaptive quantizer control · 80a4f559
      Jingning Han authored
      This commit enables a background detection approach for adaptive
      quantizer control. It combines the cyclic refresh pattern and the
      background information to determine the segment id for adaptive
      quantizer selection, prior to the non-RD mode decision process.
      It hence allows proper quantization information update for a more
      precise rate-distortion modeling in the non-RD mode decision.
      
      The compression performance of speed -5 for rtc set is improved
      by 2.5%, at no speed change.

      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.

      Remove redundant buffer initialization and mode_info assignments · b6ec6930
      Jingning Han authored
      There is no need to initialize source/dst frame buffers at frame
      level. These will be done at block coding stage. This commit hence
      removes the redundant operations.

      Enable more precise background detection for partition decision · e88a2805
      Jingning Han authored
      This commit compares the current original frame to the previous
      original frame at 64x64 block level and decides if the entire
      block belongs to background area. If it is in the background area,
      skip non-RD partition search and copy the partition types of the
      collocated block in the previous frame.
      
      For vidyo1 in the rtc set, this makes the speed -5 coding speed
      about 8% faster. The overall compression performance is down by
      1.37% for rtc set.

      Select prediction filter type in non-RD mode decision · 06ec873f
      Jingning Han authored
      This commit allows the non-RD mode decision flow to  select
      prediction filter type in NEWMV mode. It provides 8.14% compression
      performance gains in both settings of AQ=0 and 3. The current speed
      impact is about 5% to 10% slower.

      Apply finer quantizer to partition search frames in non-RD flow · 99893f24
      Jingning Han authored
      This commit optimizes the bit allocation for the non-RD coding flow.
      It applies slightly better quantizer to the frames, where all blocks
      run a non-RD partition search. Such frames typically have better
      rate-distortion trade off, thus improving the reconstruction quality
      for next few frames reference at reasonably low increment in rate
      cost.
      
      The coding performance for rtc set at speed -5 with error-resilient
      tuned on and rate control set as cbr is improved by 19.58%. It improved
      the coding speed by about 10% for a portion of local test clips.

      Motion referenced partition search for non-RD coding flow · abdb0650
      Jingning Han authored
      This commit enables the non-RD mode decision coding flow to
      adaptively apply partition search in non-refresh frame, when the
      collocated block in previous frame suggests there might be a motion
      activity. It refactors the update_state_rt() function to support
      buffer swap of mode_info struct, thereby unifying the encoding
      stage across various non-RD coding modes.
      
      It provides 5% compression performance gains in speed -6 for rtc
      test set, at about 12% speed slow down.
