      Substantial restructuring of AQ mode 2. · e68c8dcf
      Paul Wilkins authored
      The restructure moves the decision into the rd pick
      modes loop and makes a decision based at the 16x16
      block level instead of only the 64x64 level.
      
      This gives finer granularity and better visual results
      on the clips I have tested. Metrics results are worse
      than the old AQ2 especially for PSNR and this mode
      now falls between AQ0 and AQ1 in terms of visual
      impact and metrics results.
      
      Further tuning of this to follow.
      
      It should be noted that if there are multiple iterations
      of the recode loop the segment for a MB could change
      in each loop if the previous loop causes a change in the
      complexity / variance bin of the block. Also where a block
      gets a delta Q this will alter the rd multiplier for this block
      in subsequent recode iterations and frames where the
      segmentation is applied.

      Use average mb energy from first pass in AQ2 test. · 00e3626e
      Paul Wilkins authored
      AQ2 modified to use mb_av_energy in defining variance
      thresholds used alongside complexity when defining the
      segment to be used for an SB64.
      
      Slight improvements in metrics (ssim and PSNR).

      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.

      Add variance restriction to AQ2. · d0312379
      Paul Wilkins authored
      Add an additional restriction to bit/complexity based
      segmentation based on spatial variance.
      
      Only lower Q when both the number of bits spent
      in the initial encoding pass and the spatial complexity are
      below a threshold. This will prevent the low Q segments
      being used just because there is a surfeit of bits.
      
      Small metrics gains especially opsnr.
      derf ~0.2% std-hd ~0.3%

      Adapt strength of AQ2. · adf4293e
      Paul Wilkins authored
      Adapt the use of segmentation in AQ mode 2 based on
      the ambient kf/arf/gf Q.
      
      Disable segmentation where the rate per SB is very
      low and overheads are likely to outweigh the benefits.
      
      This patch reduces the -ve average metrics impact
      of AQ mode 2 while allowing stronger 3 segment AQ
      in some cases. Average improvement ~0.5-1.0%.

      Fix AQ mode 2 bug where delta causes Q 0. · 090d0798
      Paul Wilkins authored
      In Aq mode 2 for kf/arf/gf the segment q delta
      is calculated and then applied by re-quantization without
      going through the rd loop again. If the base Q != 0
      but the segment Q == 0 (lossless) this can could give rise
      to a situation where we have an illegal combination of
      transform size and Q. (Q == 0 requires that all blocks
      are coded 4x4 WHT).
