      Remove the itrans DSPR2 sources. · 77f792f0
      Tom Finegan authored
      These files define functions that are unused. Update CMake
      and configure builds to remove references and delete the
      source files. These files defined the DSPR2 specializations
      of high bit depth versions of the following functions:

      - av1_iht8x8_64_add

      intrabc: consider mode cost in RD selection · 8dc0092f
      Hui Su authored
      Should take the overhead into consideration when intrabc is not
      being used. Did not see much coding gain with this patch though.

      Add a q index based frame superres mode · 7166f22a
      Debargha Mukherjee authored
      Refactors and adds superres-mode 3 and associated
      paramters --superres-qthresh and --superres-kf-qthresh
      that are used to trigger superres mode when the qindex
      for any frame exceeds the thresholds provided for non-key
      and key-frames respenctively. The superres scale factor
      numerator is progressively reduced from 16 starting from
      that q threshold following a fixed slope.

      This patch fixes a regression introduced in 1d190950 where the encoder
       was using the 16x16 VP9/AV1 transforms for RDO, but then used the Daala
       transforms for encoding.

      Add encoder support for multi-layer GF 16 · 8dd1c980
      Zoe Liu authored
      Currently the use of the new multi-layer GF group of 16 is guarded by
      the macro USE_GF16_MULTI_LAYER, which is turned off. Hence this CL
      does not change any of the encoder behavior.

      Further refactor setup_ref_mv_list · d1121fa3
      Yunqing Wang authored
      This patch follows the previous refactoring patch, and further reduces
      the number of calls made to scan_row_mbmi and scan_col_mbmi by going
      through partition blocks instead of mi blocks. This patch doesn't change
      bitstream, which was proven by Borg test result.
      The baseline decoder speed test on 1080p clip showed that the average
      decoder speedup was 1.1%.(fps: 32.626 --> 32.994)

      Hide repeated arguments in calls to count_segs in count_segs_sb · 114e81a3
      Rupert Swarbrick authored
      The calls to count_segs appear very different from each other, but
      this is really just because of line wrapping (enforced by the
      clang-format linter). This patch produces equivalent code but the
      results are far easier to read.

      Simplify get_partition() implementation · 136d5c17
      Rupert Swarbrick authored
      This function is given a bsize and an mi array and has to figure out
      what partition to use to divide the given bsize in the direction of
      the sizes it finds in the mi array. (Since each block size can be
      reached by only one sequence of partitions, this can be done
      The previous version was correct, working by looking up entries in the
      partition_lookup array. Unfortunately, that lookup isn't quite enough
      when CONFIG_EXT_PARTITION_TYPES is true, so it then had to do some
      slightly confusing computations to fix things up after the fact.
      The new version should be more self-explanatory and doesn't work by
      looking things up in a magic array. It looks up the width and height
      corresponding to bsize and compares them with the width and height
      corresponding to the sb_type at mi_row,mi_col in the mi array. When
      CONFIG_EXT_PARTITION_TYPES is false, this is all you need, and the
      four corresponding cases can be found by a lookup in an array of 4
      With extended partition types and a sufficiently large block, you have
      to do a bit more searching. For example, if bsize is BLOCK_16X16 and
      the subsize is BLOCK_8X8, the partition might be PARTITION_SPLIT, but
      it might be one of PARTITION_HORZ_A or PARTITION_VERT_A instead. The
      new code adds some comments to explain what's going on.
      A nice side-effect of rewriting get_partition in this way is that it
      lets us completely dispense with the partition_lookup array.
      The patch also fixes comments for the A/B extended partitions in
      enums.h, which were slightly backwards (a "horizontal split means two
      blocks vertically above one another)

      aom-qm: Fix overflow in quantizer calculation · 568b7c7e
      David Barker authored
      By using a combination of a small qmlevel and large qindex,
      it is possible for the quantizer 'dqv' to end up > 2^15.
      This currently causes dqv to overflow, so widen its type
      to avoid that.
      Note that this is certainly an extreme case, but not entirely
      useless - if using a 32x32 transform, the dequantized value
      can be as small as dqv/2, which may still fit in 16 bits.

      Clarify comment in av1_set_mb_mi() · ee0fd929
      David Barker authored
      The code currently pads the decoded frame width and height to a
      multiple of 8 luma pixels, but there is a TODO suggesting that
      this may be changed to only require a multiple of 4 in future.
      But, as per the comments on the linked bug, there are good reasons
      to keep the decoded width and height as multiples of 8. So delete
      the outdated TODO and instead outline the reasons why the current
      behaviour is helpful.
