      Add frame_marker experimental flag · 1033ca0a
      Jingning Han authored
      The frame index in natural display order is needed by several
      experiments, hence move it as a root experiment. The additional
      overhead cost associated with frame_marker is below 0.05% level.

      Add striped_loop_restoration experiment · 1e7f2d0c
      Ola Hugosson authored
      This experiment offset the filter tile grid 8 pixels upwards.
      Deblocked pixels (rather than CDEFed pixels) are used for the
      2 lines above and below the filter processing unit. The 8 pixel
      offset is the offset produced by deblock/cdef. This way the
      loop_restoration does not need additional line buffers in a
      single pass hardware implementation.

      Add deblock_13tap experiment · 4ce85214
      Ola Hugosson authored
      This change enables using 13 taps for luma plane deblocking and 5 taps for
      chroma plane deblocking when pixels are in flat area.
      
      The aim for the experiment is to make sure that luma line 57 and chroma
      line 29 of the current superblock is not changed by the deblocking process
      of the superblock below. Previously this was already the case for luma
      line 56 and chroma line 28 (but not for 57 and 29).
      
      This experiment is part of an effort to reduce the overall line buffer
      size for DEBLOCK+CDEF+LR. With this change it is possible to CDEF line
      -8 to +55 direcly on the output of deblock (which require line +56 and
      +57 to be final).

      Add experiment to restrict compressed header · 2eada612
      Debargha Mukherjee authored
      The compressed header is now used only when the refresh
      type is set as forward, i.e. in error resilience and
      frame parallel modes. As long as backward updates are
      used the header is disabled thereby saving bits.

      Search for deblocking filter level for superblock · f572cd30
      Cheng Chen authored
      Search and pick filter level for each superblock after the entire
      frame has been encoded. And then apply loop filtering using
      selected filter levels.
      
      Now it can't work with LOOPFILTER_LEVEL. Y, U, V planes share the
      same filter level.
      
      Per superblock, filter levels are signaled via bitstream.
      
      Future work: move selecting filter level into each superblock
      rather than wait for the whole frame encoded.

      Tune the decision on the GF group interval · 4c3d4767
      Zoe Liu authored
      The change is purely an encoder-side tuning, which constrains a GF
      group interval to be either 8, or 12, or a number larger than 12
      (maximum of 16). The change is under ext_refs.
      
      This work has been part of the summer internship effort by chendixi@.
      
      Further, this CL removes the experiment of flex_refs and merges it
      into ext_refs, as flex_refs has been completely focused on the encoder
      side optimization for ext_refs.
      
      On Google test sets, above (stillness + interval enforcement) achieve
      a coding gain in BDRate as follows, compared against the AV1 baseline
      with all tools enabled by default (excluding ext-tx, global-motion,
      and convolve-round for speed concern):
      
      lowres: avg_psnr -0.193%; ovr_psnr -0.370%; ssim -0.332%
      midres: avg_psnr -0.556%; ovr_psnr -0.680%; ssim -0.798%

      Tom Finegan authored
      Avoid changing the public API based on an experiment flag:
      
      - Remove aom_config.h include from aom_image.h.
      - Unconditionally include the existing API additions.
      - Add some missing doc comments (silences Doxygen warnings).
      - Return an error when using ctrl flags that require
        CONFIG_COLORSPACE_HEADERS when it's not enabled.
      - Move colorspace_headers to the correct section of configure.
      - Move CONFIG_COLORSPACE_HEADERS to the correct section of
        aom_config_defaults.cmake.
      - clang-format style check appeasement

      Add dependency of ext-comp-refs on one-sided-compound · 5a978838
      Zoe Liu authored
      When ext-comp-refs is enabled, one-sided-compound is enabled by default,
      which ensures the use of ext-comp-refs is an extension of
      one-sided-compound. Both coding tools allow the use of same-sided
      reference frame pairs for compound prediction.
      
      Also, remove the dependency of ext-comp-refs on var-refs, i.e. these two
      coding tools can be independently enabled. They can still work together
      if both are enabled simultaneously.

      Disable only coding transform SIMD for DAALA_TX · 1d190950
      Monty Montgomery authored
      Rather than disabling MMX (well, all of SIMD) for daala transforms,
      selectively disable the AV1 TX SIMD through
      av1/common/av1_rtcd_defs.pl
      
      This also requires quite a few testing build fixups.

      Add 4-point DST to DAALA_DCT4 experiment · 573cf25f
      Monty Montgomery authored
      CONFIG_DAALA_DCT4 currently force-enables CONFIG_DCT_ONLY due to a
      missing 4-point DST.  The DST had not been included because it was a
      significant coding performance loss; this turned out to be a bug that
      has since been corrected.
      
      This patch adds a 4-point type IV DST to the DAALA_DCT4 experiment.
      There is a small coding performance loss in using the type IV over
      AV1's current type VII.
