      vpx_codec_enc_init_multi: fix segfault w/vp9 · 81d66e2c
      James Zern authored
      vp9 does not support multi-res encoding, the request should not crash.
      + encode_api_test: unconditionally expose multi-res test
      vpx_codec_enc_init_multi should fail independent of
      CONFIG_MULTI_RES_ENCODING if not for the same reason.

      vp9 svc: Allow denoising next to highest resolution. · c1e511fd
      Jerome Jiang authored
      Denoise 2 spatial layes at most.
      Add noise sensitivity level 2 for vp9 such that applications can control
      whether to denoise the second highest spatial layer.
      Add tests to cover this case.

      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
      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
      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
      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.

      Make the row based multi-threaded encoder deterministic · 10a497bd
      Yunqing Wang authored
      This patch followed allow_exhaustive_searches feature modification and
      continued to modify the encoder to achieve the determinism in the row
      based multi-threaded encoding. While row-mt = 1 and using multiple
      threads, the adaptive feature in encoder was disabled, which gave
      BDRate gain(at speed 1, -0.6% ~ -0.7%; at speed 2, -0.46% ~ -0.59%),
      but some encoder speed losses(7% ~ 10% at speed 1 and 3% ~ 6% at
      speed 2). These speed losses were acceptable considering the speed
      gains obtained from row-mt.

      VP9 motion vector unit test · 1aa46abb
      Yunqing Wang authored
      To prevent the motion vector out of range bug, added a motion vector unit
      test in VP9. In the 4k video encoding, always forced to use extreme motion
      vectors and also encouraged to use INTER modes. In the decoding, checked if
      the motion vector was valid, and also checked the encoder/decoder mismatch.
      The tests showed that this unit test could reveal the issue we saw before.

      vp9: Rename new_mt to row_mt · 58816014
      Vignesh Venkatasubramanian authored
      new_mt is a very generic name that will get obsolete soon enough.
      Since this is exposed as a codec control, renaming it to row_mt to
      signify row level paralellism. Also renaming the ETHREAD_BIT_MATCH
      codec control to ROW_MT_BIT_EXACT.

      The bitstream bit match test in multi-threaded encoder · 318ca076
      Yunqing Wang authored
      While the new-mt mode is enabled(namely, allowing to use row-based
      multi-threading in encoder), several speed features that adaptively
      adjust encoding parameters during encoding would cause mismatch
      between single-thread encoded bitstream and multi-thread encoded
      bitstream. This patch provides a set_control API to disable these
      features, so that the bit match bitstream is obtained in the unit
