      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).

      Added an experiment "bidir_pred" for backward prediction · cf5083d4
      Zoe Liu authored
      Major parts have been implemented as follows:
      (1) Added BRF_UPDATE, LASTNRF_UPDATE, and NRF_UPDATE in firstpass.c;
      (2) Added the handling for the scenario of
      "cpi->common.show_existing_frame == 1" at the encoder;
      (3) Added a new reference frame of BWDREF_FRAME;
      (4) Have bwd-ref work with upsampled references.
      
      Note that when the experiment of "ext_refs" turned on, this experiment
      will be turned off automatically currently.
      
      RD performance in Overall PSNR has been improved, compared against the
      VP10 baseline:

      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.

      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.

      vp9/10: improve support for render_width/height. · 812945a8
      Ronald S. Bultje authored
      In the decoder, map this to the output variable vpx_image_t.r_w/h.
      This is intended as an improved version of VP9D_GET_DISPLAY_SIZE,
      which doesn't work with parallel frame decoding. In the encoder,
      map this to a codec control func (VP9E_SET_RENDER_SIZE) that takes
      a w/h pair argument in a int[2] (identical to VP9D_GET_DISPLAY_SIZE).
      
      Also add render_size to the encoder_param_get_to_decoder unit test.

      Expose params min-gf-interval/max-gf-interval · 98526433
      Debargha Mukherjee authored
      Adds two new vp9 parameters --min-gf-interval and --max-gf-interval
      to enable testing based on frequency of alt-ref frames.
      
      Also adds a unit-test to test enforcement of min-gf-interval.
      
      For both these parameters the default value is 0, which indicates
      they are picked by the encoder, based on resolution and framerate
      considerations. If they are greater than zero, the specified
      parameter is honored.
      
      (Additional note by paulwilkins)
      Note that there is a slight oddity in that key frames are also GFs and
      considered part of  GF only group. However they are treated as not
      being part of an arf group because for arf groups the previous GF is
      assumed to be the terminal or overlay frame for the previous group.
