      Remove 'last_layer_id' from ObuDecInputContext · a8de8819
      David Barker authored
      Previously, if we wanted to use all-layers mode, the code
      in obudec.c was responsible for carving up temporal units
      into spatial layers to feed into the decoder. Whether we were
      in this mode corresponded to whether last_layer_id is set to
      Now, the all-layers behaviour is implemented in the decoder proper,
      so we can always pass a full temporal unit at a time into the decoder.
      This means that the special code in obudec.c is no longer needed,
      and that all-layers mode now works correctly for "contained" streams
      (ie, annexb format, .ivf, .webm, etc.)

      Includes clean up. · dd3e2a5f
      Tom Finegan authored
      - Remove includes of config.h wrapped by HAVE_CONFIG_H. This
        is an obsolete vestige of our libvpx ancestry.
      - Change (nearly) all remaining include sites; use proper path
        to the include relative to project root instead of ./.
      - Correct include order where appropriate.
        - Note: This part of this patch is NOT exhaustive. In an
          attempt to be conseravative about the impact of this change
          I limited ordering and grouping changes to places that
          appear extremely unlikely to cause a problem. A more exhaustive
          follow up might be appropriate, but this issue can likely be
          handled organically from here on out.

      aomdec: Fix scalable streams in non-annex-b, .obu format · 8c53d27c
      David Barker authored
      There is some special-case code in obudec.c to split each temporal unit
      up into multiple "chunks", one per spatial layer. This is used by
      examples/scalable_decoder.c to extract both spatial layers of its input,
      so that further processing can be applied.
      Unfortunately, in its current form, this code causes aomdec to break
      when given a scalable stream. But it's fairly straightforward to adjust
      the special-case code so that it isn't triggered by aomdec. Then we will
      get the same behaviour as we would get if the stream were in annex-b format,
      or in a container.
      That is, aomdec will pass a full temporal unit at a time into libaom.
      The current behaviour of libaom in this case is to output a single
      frame from each temporal unit - the frame chosen is the last (and so
      highest-spatial-layer) show or show-existing frame within the temporal
      Given that the intent of spatial scalability is for each temporal
      unit to contain multiple versions of the "same" picture, with different
      sizes/qualities, this seems like the behaviour a "typical" application
      would want, and is useful for conformance testing.

      Simplify Daala forward TX toplevel for constant shift · a2d40a39
      Monty Montgomery authored
      Rather than backing out all the LGT-related shifting matrices
      throughout the existing TX code, separate out and simplify Daala
      forward TX into a single dedicated entry point.  When DAALA_TX is
      enabled, CONFIG_HIGHBITDEPTH is also forced, and all of Daala TX
      (lowbd and highbd) uses this single TX dispatch.
      At present, this should result in no effective functional change,
      however rectangular transforms are now always column-first-- that
      has minor rounding effects.

      Adding loop wiener restoration · 8b0a5b87
      Debargha Mukherjee authored
      Adds a wiener filter based restoration scheme in loop which can
      be optionally selected instead of the bilateral filter.
      The LMMSE filter generated per frame is a separable symmetric 7
      tap filter. Three parameters for each of horizontal and vertical
      filters are transmitted in the bitstream. The fourth parameter
      is obtained assuming the sum is normalized to 1.
      Also integerizes the bilateral filters, along with other
      refactoring necessary in order to support the new switchable
      restoration type framework.
      derflr: -0.75% BDRATE
      [A lot of videos still prefer bilateral, however since many frames
      now use the simpler separable filter, the decoding speed is
      much better].
      Further experiments to follow, related to replacing the bilateral.
