      Compute mode costs from cdf · ba47c842
      Yue Chen authored 
      Previously, a lot of costs are computed from per-frame-updated
probs, which cannot reflect the actual entropy models even if we
just consider initial entropy models in cm->fc for each frame.
For most symbols, cost update is still on per frame basis in this
patch, unless cdf is updated in RDO.

Performance change: -0.011 lowres

      Use the bottom right 4x4 block for 8x8 unit mv reference · 74978fcb
      Jingning Han authored 
      When accessing an 8x8 block for motion vector referencing, always
use the bottom right 4x4 block's motion information.

      Use 4x4 granularity for nearest neighbor mv search · d37b83d8
      Jingning Han authored 
      Search the immediate neighbor for reference motion vectors in the
unit of 4x4 block size. This improves the compression performance
by 0.05%.

      Use 8x8 block mv search for sub8x8 blocks · 7f99477a
      Jingning Han authored 
      Use 8x8 block search resolution for reference motion vectors for
non-nearest neighbors of a sub8x8 coding block. The compression
performance is slightly up by 0.05%.

      Make braces consistent in encodeframe.c · 50b0f6ca
      Cheng Chen authored 
      Enable vim to jump to correct corresponding braces, which
is helpful especially when the function is long.

      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).
