      Fix bug in highbd wedge-interintra prediction · b746c3b7
      David Barker authored
      When calling aom_(highbd_)blend_a64_mask for a subsampled plane,
      the mask is subsampled in-place. This means that the mask stride
      passed in needs to be the value before subsampling. Since the
      wedge masks are set up so that mask stride = mask width, this means
      that the stride should equal the width of the current mi block.
      
      However, for the wedge-interintra path in combine_interintra_highbd,
      we subsampled the mask stride, resulting in the wrong stride being
      used for chroma planes if subsampling_x == 1.
      
      The lowbd path already uses the correct stride, so this patch just
      copies the stride calculation over to the highbd path.

      Tidy up and generalise av1_predict_intra_block · 914d53a1
      Rupert Swarbrick authored
      This tidies up the code somewhat, factoring the snapshot/restore of
      rows and columns in the reference frame into a separate function. The
      variable names might also be a little easier to follow.
      
      The generalisation is that av1_predict_intra_block no longer requires
      that a rectangular block is exactly 2:1 or 1:2. The new code will also
      allow tiling a rectangular transform size (say two 1:2 transforms to
      make a 1:4 transform).

      Add txmg experiment · ad653a39
      Angie Chiang authored
      This experiment aims at merging lbd/hbd txfms
      
      So far this exp uses hbd transform on lbd path.
      The performances I observed are
      lowres -0.089%
      midres  0.065%
      (negative means performance drop)
      
      Started from here, two main things are needed to be done.
      1) Fix overflow due to quantizer noise
      2) Generate a 16-bit version from the hbd txfm

      Fix inconsistency in compound-segment masks · fc256542
      David Barker authored
      The value of 'mask_base' passed to diffwtd_mask is currently
      38 for the lowbd path and 42 for the highbd path. Going off of
      the mode name (DIFFWTD_38), presumably these are both supposed
      to be 38, so change the highbd path accordingly.

      Enable flex-refs by default when altref2 is on · 438b3ae7
      Zoe Liu authored
      Compared against baseline with default enabled tools (except for
      ext-tx and global-motion for speed concern):
      
                       altref2 -> altref2 + flex-refs
      lowres: avg_psnr -0.395% -> -0.460%
      midres: avg_psnr -0.418% -> -0.478%
      
      In particular, flex-refs improves the coding performance for the
      following 3 clips while no impact on all other clips:
      
      bowing_cif.y4m:    avg_psnr  0.023% -> -1.022%
      pamphlet_cif.y4m:  avg_psnr  0.454% -> -1.111%
      snow_mnt_480p.y4m: avg_psnr -0.162% -> -1.948%
