      frame_superres: Send scale every frame · 846d67dd
      Fergus Simpson authored
      The superres scale was accidentally only sent if the current frame was
      a key frame or if the current resolution was not used by any of the
      reference frames. This patch separates the superres scale from the
      current resolution to simplify its coding and makes sure that it is
      written for every frame.

      frame-superres: Pre-encode downscaling · 3502d08b
      Fergus Simpson authored
      Adds handling needed for the pre-encode downscaling for superres
      encoding. Makes use of the existing resizing functionality, just
      adjusting the target resolution after the resize logic and before the
      resize has actually occurred.
      
      Since the upscaling portion of superres is not yet implemented, superres
      scaling is not yet allowed to trigger. The numerator is set to be equal
      to the denominator and the superres_pending flag is not set.

      Add CONFIG_INTERINTRA flags and reduce # of interintra modes to 4 · 4d26acb4
      Yue Chen authored
      Use CONFIG_INTERINTRA to properly separate interintra from the basic
      ext_inter experiment.
      When macro REDUCE_INTERINTRA_MODES is 1, only 4 ii modes are enabled
      so as to reduce the complexity overhead.
      (Right now the flag is off)

      Fix for the use of prev frame mvs when ext-refs is on · 40a42d4b
      David Barker authored
      Also fix a mismatch for resizing with ext-refs enabled.
      
      There are various preconditions which need to be true for it to
      be valid to set cm->use_prev_frame_mvs = 1, including that the
      sizes of this frame and cm->prev_frame must be equal.
      
      With ext-refs enabled, we would sometimes decide to change
      cm->prev_frame to point to the LAST_FRAME reference, without
      re-checking the preconditions. If the LAST_FRAME was smaller
      than the current frame, this could lead to reading garbage off the
      end of its mv array, and eventually to an encode/decode mismatch.
      
      We fix this by rewriting the preconditions as checks on
      cm->prev_frame directly (rather than using cm->last_width and
      cm->last_height), and by testing the preconditions after any
      possible adjustment.
      
      This should not affect the bitstream unless ext-refs is enabled,
      but may affect the bitstream with ext-refs even if resizing is
      not used.

      [CFL] Store luma as prediction for chroma · e3980281
      Luc Trudeau authored
      Stores the reconstructed luma pixels for each transform block inside a
      prediction block. Rectangular transform blocks are supported.
      
      As for RDO, after all the modes have been tested for luma, an extra
      encoding is perform in order to store the reconstructed pixel values of
      the best mode. These values are then used for RDO on the chromatic
      planes.

      [CFL] Custom block-level DC_PRED · f8164157
      Luc Trudeau authored
      Adds the CfL experiment flag and computes a block-level DC_PRED that is
      required by CfL in order to compute alpha_cb and alpha_cr.
      
      The rate-distorsion impact of computing DC_PRED at the prediction block level
      for chroma planes is rather small
