      TX64x64: zero the coeffs after top-left 32x32 block. · 2d4ac634
      Urvang Joshi authored
      This is to get an approximation of 64x64, 32x64 and 64x32 transforms.
      Compression performance is neutral for lowres and midres sets.

      Make rd/enc optimize_txb uses same fast_mode · 87278292
      Angie Chiang authored
      The performance drop introduced by inconsistency decision between
      optimize_txb in rd loop and final encoding phase.
      By making them use the same fast_mode,  will speed up encoder
      without having the performance drop

      Make pickrst.c more efficient · 2ec2a6f1
      Rupert Swarbrick authored
      The try_restoration_tile function now works by calling
      av1_loop_restoration_filter_unit rather than
      av1_loop_restoration_filter_frame. This is rather more efficient,
      because it only works on the unit in question, rather than memcpy-ing
      the rest of the frame.

      Expose av1_loop_restoration_filter_unit in restoration.h · dd6f09ab
      Rupert Swarbrick authored
      This patch also does a certain amount of rejigging for loop
      restoration coefficients, grouping the information for a given
      restoration unit into a structure called RestorationUnitInfo. The end
      result is to completely dispense with the RestorationInternal
      The copy_tile functions in restoration.c, together with those
      functions that operate on a single stripe, have been changed so that
      they take pointers to the top-left corner of the area on which they
      should work, together with a width and height.
      The same isn't true of av1_loop_restoration_filter_unit, which still
      takes pointers to the top-left of the tile. This is because you
      actually need the absolute position in the tile in order to do striped
      loop restoration properly.
