      Add --enable-dist-8x8, rename existing '--tune' as '--tune-metric' · d808bfcf
      Yushin Cho authored
      Added 'cdef-dist' and 'daala-dist' options to --tune-metric'.
      (Actual bodies of the options will be added in later separate commits)
      
      Also, if --tune=cdef-dist or --tune=daala-dist,
      enable-dist-8x8 is automatically turned on.
      
      This commit is a part of prep-work to remove DIST_8X8, CDEF_DIST,
      and DAALA_DIST experimental flags.

      Make EXT_TILE compatible with TILE_GROUPS · eeb08a9b
      Yunqing Wang authored
      Added a 1-bit flag 'large_scale_tile'. If it is 0 that is the default value,
      use normal tile coding in TILE_GROUPS. If it is 1, use large-scale tile
      coding in EXT_TILE.
      
      At large_scale_tile=1 case, if single-tile-decoding is required, then the
      loopfilter is disabled.
      
      Related API and unit tests were modified.

      Add the motion vector unit test · ff4fa068
      Yunqing Wang authored
      This unit test was ported from VP9. To prevent the motion vector out of
      range bug, added a motion vector unit test. 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.

      ext_tile: add 2 tile encoding modes · d8cd55f4
      Yunqing Wang authored
      Added 2 tile encoding modes:
      TILE_NORMAL mode supports the large-scale tile coding up to 1024 x 1024
      tiles;
      TILE_VR mode supports the large-scale tile coding and also the decoding
      of a single tile.
      
      TILE_NORMAL mode allows the non-vr content to be encoded in multiple tiles
      without using the coding tool that are designed for vr applications.

      Add an experiment to disable lpf on tile boundaries · 7386eda0
      Ryan Lei authored
      This commit adds a new experiment to allow disabling of loop filtering
      on tile boundaries. It is implemented by adding a syntax field
      "loopfilter_across_tiles_enabled" into the uncompressed frame header. 
      If it is set to 0, decoder and encoder will disables loop filtering for
      block edges that are also tile boundaries.

      Add options setting number of tile groups or MTU. · af6df175
      Thomas Davies authored
      Default MTU size is 0, which implies a fixed number
      of tile groups. MTU matching overrides fixed tile
      group. MTU matching will succeed unless a single
      tile is bigger than the MTU.
      
      --mtu-size is in bytes, and includes headers but
      not transport/wrapper overheads

      Merge bi-predictive frames to EXT_REFS · 5805a14c
      Zoe Liu authored
      This patch removed the experiment of BIDIR_PRED and merged the feature
      into the experiment of EXT_REFS:
      
      (1) Each frame now has up to 6 reference frames, namely
          LAST_FRAME, LAST2_FRAME, LAST3_FRAME, GOLDEN_FRAME, (forward) and
          BWDREF_FRAME, ALTREF_FRAME (backward);
          LAST4_FRAME has been removed;
      (2) First pass still keeps the 8 updates:
          KF_UPDATE, LF_UPDATE, GF_UPDATE, ARF_UPDATE, OVERLAY_UPDATE, and
          BRF_UPDATE, LAST_BIPRED_UPDATE, BI_PRED_UPDATE;
      (3) show_existing_frame==1 is supported in the experiment of EXT_REFS;
      (4) New encoding modes are added for both single-ref and compound cases,
          through the use of the 2 extra forward references (LAST2 & LAST3)
          and the 1 extra backward reference (BWDREF).

      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).

      Recover tile coding performance · bdcc1405
      Yunqing Wang authored
      After porting tile coding from VP9 to VP10, some performance
      degradation was seen because of the difference between VP9 and
      Vp10 baseline. This patch disabled some features in VP10 while
      tile coding is turned on. Also, an encoder control API was added
      back for this use case.
