      Add VAR_TX_NO_TX_MODE experiment. · a33304f0
      Nathan E. Egge authored
      This experiment removes the tx_mode flag from the uncompressed frame
       header and instead always uses a constant value.

      Wei-Ting Lin authored
      Define the syntax and entropy coding templates for
      NCOBMC_ADAPT_WEIGHT. The actual values of the default
      probabilities and the index tree structure need to
      be fine tuned.
      
      In this experiment all mv's in a superblock are sent
      first as in the ncobmc case.

      supertx: Read and write transforms with CDF in decode_partition · 580943a7
      Rupert Swarbrick authored
      Patch b1bedf5f converted the three writes in bitstream.c that
      specify an extended transform from using av1_write_token (encoded with
      probability trees) to aom_write_symbol (encoded with CDFs).
      
      That patch fixed up the two reads in decodemv.c but didn't fix up the
      corresponding read in decodeframe.c. This patch does so.
      
      The patch also fixes up a write of a (non-extended) transform when not
      CONFIG_EXT_TX and the corresponding read.

      Add chorma tilesize option in loop-restoration · 84f567c7
      Debargha Mukherjee authored
      Adds an option bit in the bitstream syntax to allow chroma to
      have restoration tilesize that is coupled to luma based on
      subsmapling of the color components.
      
      This is meant to ease encoder hardware implementation.

      cb4x4: Move sub-4X4 block sizes behind chroma flags. · 81ec2619
      Timothy B. Terriberry authored
      cb4x4 itself should not require these sizes.
      
      This simplifies compatibility with other experiments, since we can
      first make them work with cb4x4 (which is now on by default), and
      then worry about chroma_sub8x8 and chroma_2x2 (which is not) in
      separate steps.
      
      Encoder and decoder output should remain unchanged.

      ext_inter: Skip compound type probs. for small block sizes. · 4a81001b
      Timothy B. Terriberry authored
      When writing the compressed header, prob_diff_update() was called
      for compound_type_prob[] for every defined block size, even though
      luma never uses block sizes smaller than 4x4.
      
      This fixes is_any_masked_compound_used() and
      is_interinter_compound_used() to properly return 0 for chroma-only
      block sizes, and then uses these functions to guard the probability
      updates in write_compressed_header() and read_compressed_header(),
      the same way the actual compound type values are guarded in
      read_inter_block_mode_info() and pack_inter_mode_mvs().

      Add new coding tool of ext-comp-refs · c082bbcb
      Zoe Liu authored
      The tool of ext-comp-refs adds the uni-directional compound reference
      prediction. In details, 3 pairs of uni-direcitonal compound references
      are added for the comp ref prediction:
      (LAST_FRAME, LAST2_FRAME),
      (LAST_FRAME, GOLDEN_FRAME), and
      (BWDREF_FRAME, ALTREF_FRAME).
      
      This new tool of ext-comp-refs will eventually overwrite
      one-side-compound and have the two coding tools to merge to one.
      
      It achieves -0.35 ~ -0.55% coding gains in BDRate, compared against
      AV1 baseline with the default experiments on, but without
      one-sided-compound. It achieves -0.2% ~ -0.3% coding gains when
      one-sided-compound is on. It achieves larger gains on higher
      resolution.

      Add encoder/decoder pipeline to support single ref comp modes · 85b66463
      Zoe Liu authored
      Now the single ref comp mode should work with WEDGE and
      COMPOUND_SEGMENT. For motion_var, the OBMC_CAUSAL mode uses the 2nd
      predictor if the neighboring block is single ref comp mode predicted.
      
      This patch removes the mode of SR_NEAREST_NEWMV and leaves four
      single ref comp modes in total:
      
      SR_NEAREST_NEARMV
      SR_NEAR_NEWMV
      SR_ZERO_NEWMV
      SR_NEW_NEWMV

      frame_superres: Post encode/decode upscaling · d2bcbb56
      Fergus Simpson authored
      This patch implements the post-encode and post-decode upscaling for the
      frame superresolution experiment to work.
      
      Upscaling happens after cdef and before loop restoration.
      
      For now, this patch forces on random-superres.
      
      The patch also cleans up some broken rate control hooks from VP9
      days, to be brought back later when the resize and superres tools
      are stable.

      Yue Chen authored
      Refactoring: split prediction+extension for each plane, so we can

      Compatibility fix: fix conflicts with cb4x4 and chroma_sub8x8, now
      for chroma sub8x8 supertx, only the top-left(basic cb4x4) or the
      the bottom-right(cb4x4 + chroma_sub8x8) predictor will be used
      without any blending within a 8x8 unit.
