      Add domain transform recursive filter · 3981be93
      Debargha Mukherjee authored
      This filter is meant to replace the bilateral filter,
      but is currently added in addition to the bilateral filter
      for testing.

      Enable tile-adaptive restoration · 5cd2ab95
      Debargha Mukherjee authored
      Includes a major refactoring/enhancement to support
      tile-adaptive switchable restoration. The framework can be
      readily extended to add more restoration schemes in the
      future. Also includes various cleanups and fixes.
      
      Specifically the framework allows restoration to be conducted
      on tiles such that each tile can be either left unrestored, or
      use bilateral or wiener filtering.
      
      There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
      
      Further enhancements will be added subsequently to improve coding
      efficiency and complexity.

      Frame can be split into rectangular tiles for application of separate
      bilateral or Wiener filters per tile. Some variable names changed for
      better readability.

      Make superblock size variable at the frame level. · 454989ff
      Geza Lore authored
      The uncompressed frame header contains a bit to signal whether the
      frame is encoded using 64x64 or 128x128 superblocks. This can vary
      between any 2 frames.
      
      vpxenc gained the --sb-size={64,128,dynamic} option, which allows the
      configuration of the superblock size used (default is dynamic). 64/128
      will force the encoder to always use the specified superblock size.
      Dynamic would enable the encoder to choose the sb size for each
      frame, but this is not implemented yet (dynamic does the same as 128
      for now).
      
      Constraints on tile sizes depend on the superblock size, the following
      is a summary of the current bitstream syntax and semantics:
      
      If both --enable-ext-tile is OFF and --enable-ext-partition is OFF:
           The tile coding in this case is the same as VP9. In particular,
           tiles have a minimum width of 256 pixels and a maximum width of
           4096 pixels. The tile width must be multiples of 64 pixels
           (except for the rightmost tile column). There can be a maximum
           of 64 tile columns and 4 tile rows.
      
      If --enable-ext-tile is OFF and --enable-ext-partition is ON:
           Same constraints as above, except that tile width must be
           multiples of 128 pixels (except for the rightmost tile column).
      
      There is no change in the bitstream syntax used for coding the tile
      configuration if --enable-ext-tile is OFF.
      
      If --enable-ext-tile is ON and --enable-ext-partition is ON:
           This is the new large scale tile coding configuration. The
           minimum/maximum tile width and height are 64/4096 pixels. Tile
           width and height must be multiples of 64 pixels. The uncompressed
           header contains two 6 bit fields that hold the tile width/heigh
           in units of 64 pixels. The maximum number of tile rows/columns
           is only limited by the maximum frame size of 65536x65536 pixels
           that can be coded in the bitstream. This yields a maximum of
           1024x1024 tile rows and columns (of 64x64 tiles in a 65536x65536
           frame).
      
      If both --enable-ext-tile is ON and --enable-ext-partition is ON:
           Same applies as above, except that in the bitstream the 2 fields
           containing the tile width/height are in units of the superblock
           size, and the superblock size itself is also coded in the bitstream.
           If the uncompressed header signals the use of 64x64 superblocks,
           then the tile width/height fields are 6 bits wide and are in units
           of 64 pixels. If the uncompressed header signals the use of 128x128
           superblocks, then the tile width/height fields are 5 bits wide and
           are in units of 128 pixels.
      
      The above is a summary of the bitstream. The user interface to vpxenc
      (and the equivalent encoder API) behaves a follows:
      
      If --enable-ext-tile is OFF:
           No change in the user interface. --tile-columns and --tile-rows
           specify the base 2 logarithm of the desired number of tile columns
           and tile rows. The actual number of tile rows and tile columns,
           and the particular tile width and tile height are computed by the
           codec ensuring all of the above constraints are respected.
      
      If --enable-ext-tile is ON, but --enable-ext-partition is OFF:
           No change in the user interface. --tile-columns and --tile-rows
           specify the WIDTH and HEIGHT of the tiles in unit of 64 pixels.
           The valid values are in the range [1, 64] (which corresponds to
           [64, 4096] pixels in increments of 64.
      
      If both --enable-ext-tile is ON and --enable-ext-partition is ON:
           If --sb-size=64 (default):
               The user interface is the same as in the previous point.
               --tile-columns and --tile-rows specify tile WIDTH and HEIGHT,
               in units of 64 pixels, in the range [1, 64] (which corresponds
               to [64, 4096] pixels in increments of 64).
           If --sb-size=128 or --sb-size=dynamic:
               --tile-columns and --tile-rows specify tile WIDTH and HEIGHT,
               in units of 128 pixels in the range [1, 32] (which corresponds
               to [128, 4096] pixels in increments of 128).

      Port large scale tile coding features from nextgen. · 490ba1ad
      Geza Lore authored
      If configured with --enable-ext-tile, the codec uses an alternative
      tile coding syntax in the bitstream. Changes include::
       - The maximum number of tile rows and columns is extended to 1024
         each.
       - The minimum tile width/height is 64 pixels (1 superblock).
       - A tile copy mode is added where a tile directly reuse the coded
         data of a previous tile
       - The meaning of the tile-columns and tile-rows codec parameters are
         overloaded to mean tile-width and tile-height in units of 64
         pixels.
       - All tiles should now be independent, including rows within the
         same columns, so large scale parallel, or independent decoding is
         possible.
       - vpxdec also gained the options to decode only a particular tile,
         tile row, or tile column.
      
      Changes without --enable-ext-tile:
       - All tiles should now be independent, including rows within the
         same columns, so large scale parallel, or independent decoding is
         possible.
       - vpxenc default tile configuration changed to use 1 tile column.

      Make encoder buffer allocation dynamic · 3807dd82
      Adrian Grange authored
      Frame buffers are now allocated dynamically on-demand.
      
      Entries in the reference frame map, cm->ref_frame_map,
      may now be set to -1 (INVALID_IDX) to indicate that
      there is not a valid reference buffer in that "slot".
      
      All slots in the reference frame map are now initialized
      to the empty state (-1) and each buffer is initialized
      to have a reference count of 0.

      Try again to merge branch 'frame-parallel' into master branch. · be6aeada
      hkuang authored
      In frame parallel decode, libvpx decoder decodes several frames on all
      cpus in parallel fashion. If not being flushed, it will only return frame
      when all the cpus are busy. If getting flushed, it will return all the
      frames in the decoder. Compare with current serial decode mode in which
      libvpx decoder is idle between decode calls, libvpx decoder is busy
      between decode calls.
      
      Current frame parallel decode will only speed up the decoding for frame
      parallel encoded videos. For non frame parallel encoded videos, frame
      parallel decode is slower than serial decode due to lack of loopfilter
      worker thread.
      
      There are still some known issues that need to be addressed. For example:
      decode frame parallel videos with segmentation enabled is not right sometimes.
      
      * frame-parallel:
        Add error handling for frame parallel decode and unit test for that.
        Fix a bug in frame parallel decode and add a unit test for that.
        Add two test vectors to test frame parallel decode.
        Add key frame seeking to webmdec and webm_video_source.
        Implement frame parallel decode for VP9.
        Increase the thread test range to cover 5, 6, 7, 8 threads.
        Fix a bug in adding frame parallel unit test.
        Add VP9 frame-parallel unit test.
        Manually pick "Make the api behavior conform to api spec." from master branch.
        Move vp9_dec_build_inter_predictors_* to decoder folder.
        Add segmentation map array for current and last frame segmentation.
        Include the right header for VP9 worker thread.
        Move vp9_thread.* to common.
        ctrl_get_reference does not need user_priv.
        Seperate the frame buffers from VP9 encoder/decoder structure.

      Multiframe Quality Enhancement(MFQE) in VP9. · 7ac3e3c1
      JackyChen authored
      It is the first version of MFQE in VP9. There are a few TODOs included
      in this version.
      Usage: Add flag --enable-vp9-postproc to config the project.
      In decoder, use flag --mfqe in the command line to enable
      MFQE in postproc.
      Note: Need to have key frame with low quality to see the effect of this
      new patch. In my experiment, I fixed the qindex to 200 in key frame.
