      Move loop restoration reset into a helper function · 76405206
      Rupert Swarbrick authored
      This seems a little cleaner than having the loop open coded in four
      places.

      Speed up ref selection by enforcing max 6 frames · f452fdfe
      Zoe Liu authored
      A speedup feature that enforces the maximum number of reference frames
      to evaluate for each arbitrary frame to be 6, as opposed to the maximum
      syntax-allowed number of reference frames which is 7, through the
      following rules:
      
      (1) When all the possible reference frames are availble, we reduce the
          number of reference frames (7) by 1 by removing one reference
          frame;
      (2) Always retain GOLDEN_FARME/ALTEF_FRAME;
      (3) Check the earliest 2 remaining reference frames, and there are two
          options to remove one reference frame:
          (a) Remove the one with the lower quality factor; Otherwise if
          both frames have been coded at the same quality level, remove the
          earliest reference frame;
          (b) Always remove the earliest reference frame.
          Currently set option (a).
      
      This patch has demonstrated an encoder speedup of ~8.5%. It is under
      speed2 with "selective_ref_frame >= 2". (May be considered to move
      to speed1 later once the coding performance impact is evaluated
      further.)
      
      Using the following configure setups, the coding performance has been
      dropped on Google test sets (50 frames) in BDRate by ~0.2% for lowres
      and by ~0.1% for midres:
      --enable-experimental --disable-convolve-round --disable-ext-partition
      --disable-ext-partition-types --disable-txk-sel --disable-txm

      Replace OD_UNBIASED_RSHIFT32() with OD_RSHIFT1(). · 49fad89a
      Nathan E. Egge authored
      Because daala_tx only ever does an unbiased shift by 1, we can replace
       the varible shift macro with a simpler hardcoded implementation.
      This patch causes no change in behavior.

      Fix build for CONFIG_DAALA_TX and CONFIG_TX64X64 · 683f70e7
      Monty Montgomery authored
      The recent 64x32 and 32x64 patches break the build when
      CONFIG_DAALA_TX and CONFIG_TX64X64 are enabled simultaneously.  This
      is a minor correction that fixes the build problem.

      striped-loop-restoration: Respect tile experiments · 921b334f
      Rupert Swarbrick authored
      As of patch https://aomedia-review.googlesource.com/c/aom/+/28821 ,
      loop-restoration units cannot cross tile borders. But the context
      around each processing unit was still allowed to cross tile borders.
      This is fine in the usual case - but, when loop filtering across tiles
      is switched off, we're supposed to be able to decode each tile completely
      independently (each tile column, if dependent-horztiles is on).
      
      Roughly, the change we need to make is:
      When loop filtering across tiles is switched off, we treat each tile
      as if it were a full frame, and extend the CDEF output for that tile
      to form a 3-pixel border around the tile. We only use deblocked
      above/below pixels for processing unit boundaries which lie inside
      a tile.
      
      In terms of the code, this is implemented in two parts. This only
      applies when the loop_filter_across_tiles_flag is false; otherwise,
      we keep the old behaviour.
      
      * For processing units at the top edge of a tile, fill the above context
        with copies of the topmost line of CDEF output *from the same tile*,
        rather than using deblocked pixels from the tile above.
        The below context of processing units at the bottom edge of a tile
        is treated analogously.
      
      * When setting up the boundary for a processing stripe at the left edge
        of a tile, fill the stripe's left boundary with copies of the
        leftmost column of CDEF output from the same tile. Again, processing
        stripes at the right edge of a tile are treated analogously.
      
        Similarly to the above/below boundaries, we store the overwritten
        pixels into a pair of left/right context buffers, and restore them
        to their original values once we've dealt with that processing stripe.
