      Add adapt_scan APIs and some helping functions · 648aeb0b
      Angie Chiang authored
      av1_init_scan_order
      initialize data structures related to adaptive scan order
      
      av1_update_scan_prob
      update nonzero probabilities from nonzero counts
      
      av1_augment_prob
      embed r + c and coeff_idx info with nonzero probabilities.
      When sorting the nonzero probabilities, if there is a tie,
      the coefficient with smaller r + c will be scanned first
      
      av1_update_sort_order
      apply quick sort on nonzero probabilities to obtain a sort order
      
      av1_update_scan_order
      apply topological sort on the nonzero probabilities sorting order to
      guarantee each to-be-scanned coefficient's upper and left coefficient
      will be scanned before the to-be-scanned coefficient.
      
      av1_update_neighbors
      For each coeff_idx in scan[], update its above and left neighbors in
      neighbors[] accordingly.

      Debargha Mukherjee authored
      Uses an array to map block sizes, y tx sizes, and subsampling
      factors to various transform sizes for UV.

      Use rectangular transforms for >= 8x8 blocks · d21982c8
      Geza Lore authored
      For rectangular blocks between 8x8 and 32x32, we can now code the
      transform size as one bigger than the largest square that fits in
      the block (eg, for 16x8, we can code a transform size of 16x16
      rather than the previous maximum of 8x8), when this oversized
      transform is coded in the bitstream, the codec will use the full
      size rectangular transform for that block (eg 16x8 transform in
      the above example).
      
      Also fixes a scaling bug in 16x8/8x16 transforms.

      Rectangular transforms 4x8 & 8x4 · e5848dea
      Debargha Mukherjee authored
      Added a new expt rect-tx to be used in conjunction with ext-tx.
      [rect-tx is a temporary config flag and will eventually be
      merged into ext-tx once it works correctly with all other
      experiments].
      
      Added 4x8 and 8x4 tranforms for use initially with rectangular
      sub8x8 y blocks as part of this experiment.
      
      There is about a -0.2% BDRATE improvement on lowres, others pending.
      
      When var-tx is on rectangular transforms are currently not used.
      That will be enabled in a subsequent patch.

      Extend superblock size fo 128x128 pixels. · 552d5cd7
      Geza Lore authored
      If --enable-ext-partition is used at build time, the superblock size
      (sometimes also referred to as coding unit (CU) size) is extended to
      128x128 pixels.

      Porting ext_partition experiment from nextgen · 5cce322a
      Julia Robson authored
      This has been ported under ext_partition_types because it is due
      to be combined with the coding_unit_size experiment which is
      already being ported under ext_partition

      Super transform - ported from nextgen branch · 3787b174
      Debargha Mukherjee authored
      Various additional changes were made to make the experiment
      compatible with misc_fixes.
      
      derflr: +0.979%
      hevcmr: +0.865%
      
      Speed-wise with --enable-supertx the encoder is only about 10%
      slower than without. Decoding impact is about 30% slowdown.
      
      Note this does not work with ext-tx or var-tx yet. That is
      a TODO.

      Add SSE2 code and unit test for VP9 denoiser. · 80465dae
      JackyChen authored
      This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are
      only 16x16 blocks in denoiser, while in VP9, there are 13 different
      block sizes.
      
      By adding this SSE2 code, the improvement of encoder speed is around
      20%(using C code vs using SSE2 code), vary for different clips.
      
      The unit test for VP9 denoiser is to confirm that the SSE2 code is
      bit-exact with the C code. The unit test covers all block size.

      Fix chrome valgrind warning due to the use of mismatched bsize · 3cddd81c
      Jingning Han authored
      This commit fixes a mismatched use case of block size in non-RD
      intra prediction check. The residual SSE and variance should be
      calculated per transform block size, instead of operating block
      size, which caused chrome valgrind warning on conditional jump
      based on uninitialized value (webm issue 823). This commit
      resolves this issue.

      Adding ss_size_lookup table. · 8db2675b
      Dmitry Kovalev authored
      Removing the old one bsize_from_dim_lookup. Now we have a way to determine
      block size for plane using its subsampling values (ss_size_lookup). And
      then we can find the number of pixels in the block (num_pels_log2_lookup).
