      vp9 svc: Rework/fix scale partitioning on boundary. · 1aea1675
      Jerome Jiang authored
      Enable partition copy on boundary and scale blocks along the boundary.
      Rename copy_partition_svc to scale_partition_svc.
      
      Do not copy if the block crosses the boundary.

      vp9-svc: Fix flag for usage of reuse-lowres partition · b3c93d60
      Marco authored
      Fix/cleaup the conditioning for usage of the reuse-lowres
      partition feature.
      
      Replace the non-reference condition with the top temporal
      layer, and put this condition in the speed feature.
      
      This prevents doing update_partition_svc() on every
      VGA frame, instead it will now only do update for VGA in
      the top temporal layer frames.
      
      Also this makes it easier to test/enable this feature
      for lower layer temporal frames.

      New content type to improve grain retention. · a73cee28
      paulwilkins authored
      For new VP9 only content type adjust  the rate distortion and ARF
      filter based on the relative spatial variance of the source and
      reconstruction.
      
      In regards to the RD loop the method favors modes where the
      reconstruction variance is similar to the source variance. However it
      is currently only applied to regions where the source variance is quite
      low.
      
      For very low variance blocks it applies a further bias against intra
      coding and large prediction block sizes (the later in particular limit
      the usefulness of the loop filter).
      
      The final part of this change is to lower the strength of the ARF
      filter for blocks where the source has very low spatial variance, to
      encourage some low amplitude texture or noise to pass through
      the filter.
      
      This change improves the retention of film grain and fine noise /
      texture in spatially flat regions, but as expected causes a significant
      drop in PSNR on many clips. This is to be expected because similar
      but misaligned noise or texture will give a lower PSNR than a flat
      noise free reconstruction. However, it is worth noting that most clips
      show a strong gain in FAST SSIM.
      
      The features are enabled on the vpxenc command line by setting
      --tune-content=film.
      
      VPX_ENCODER_ABI_VERSION bumped for this change and cvbr.

      CVBR command line option. · 93e83fd7
      paulwilkins authored
      Added command line control of Corpus VBR.
      
      The new corpus vbr mode is a variant of standard
      VBR (end-usage=0) where the complexity distribution
      mid point is passed in rather than calculated for a specific
      clip or chunk.
      
      The new variant is enabled by setting a new command line
      parameter --corpus-complexity to a zero value. Omitting
      this parameter or setting it to 0 will cause the codec to use
      standard vbr mode.
      
      The correct value for a given corpus needs to be derived
      experimentally using a training set such that the average
      rate for the corpus is close to the target value.
      
      For example our using our low res test set with upper and lower
      vbr limits of 50%-150% and a corpus complexity value of 650
      gives a similar average data rate across the set to using standard
      vbr. However, with the corpus mode easier clips will be allocated
      fewer bits and harder clips more bits rather than having the same
      rate target for all.

      Nonrd_pickmode: avoid computing UV cost when early_term is set. · 6fbc354c
      Marco authored
      For nonrd_pickmode: if early_term is set there should be
      no need to include UV in rdcost (when color_sensitivity is set).
      
      Neutral change on RTC and RTC_derf metrics, for speed >= 5.
      No change for ytlive metrics.
      
      Very small speed gain (~0.5%) on some clips with strong color content.

      Allow for compound prediction mode in nonrd_pickmode for ZEROMV.
      For real-time encoding, 1 pass with non-zero lag-in-frames.
      
      Added speed feature to control the feature.
      Enabled for speed >=6 for now, under VBR mode.
      
      avgPSNR/SSIM metrics positive on ytlive set, for speed 6:
      some clips up by ~3-5%, some clips neutral gain, average gain
      across clips is ~1%.
      
      Small/negligible decrease in speed.

      fail early on oversize frames · 5fe82459
      Johann authored
      Even though frame_size is calculated in uint64_t, it winds up in an int
      size value.
      
      This was exposed with the msan test because the memset is called with
      (int)frame_size, leading to a segfault.
