      [dist-8x8] Remove asserts for sub8x8 distortions · 796d4e29
      Yushin Cho authored
      Remove the asserts in rd_pick_partition(), which check
      whether the sum of distortions of sub8x8 partitions matches to
      the 8x8 distortion measured in final reconstructed 8x8 pixels,
      because the sum of the sub8x8 distortions returned from rd_pick_sb_modes()
      is sometimes different from what is measured with final reconstructed 8x8 pixels.
      The asserts have been provided for the purpose of sanity check with PSNR
      and triggered with "--enable-dist-8x8=1" encoder option.

      Make txk-sel support cfl in key frame coding · 60db3c95
      Jingning Han authored
      Properly store and update the luma component result in the key
      frame rate distortion optimization process for chroma component
      prediction. The txk-sel provides 0.15% gains for key frame coding
      on top of lv-map/multi and all other default experiments.

      Replace full txfm rd search with luma writing · 159f72c3
      Jingning Han authored
      The cfl route needs the reconstructed luma pixels in the chroma
      RD search. Replace an extra route of txfm_rd_in_plane with the
      use of av1_encode_intra_block_plane to directly write out the
      needed luma pixels in the key frame rate-distortion optimization
      The compression stats remain identical. The key frame encoding
      speed is on average 3% faster for a few tested 1080p clips.

      Fix txk-sel rd search in the key frames · c5c37032
      Jingning Han authored
      If the transform block selects a transform kernel type that makes
      it all zero coefficients and hits the best rd cost, store such
      decision and force the transform block to be coded as all zero
      block in the final coding pass. This makes txk-sel improve the
      kf coding performance by 0.15% now.

      Reduce the unnecessary array size · 316a6235
      Zoe Liu authored
      For partition types pruning in ext-partition-types, horz_rd and
      vert_rd are used to store the RD costs for the two blocks in
      horizontal partition and vertical partition. Hence array size of
      2 is sufficient for either array.

      Remove experimental flag of SIMPLE_BWD_ADAPT · f57a937c
      Frederic Barbier authored
      This experiment has been adopted, we can simplify the code
      by dropping the associated preprocessor conditionals.

      Properly handle the tile load size writing · 2e7d66d9
      Jingning Han authored
      Properly handle the tile load size writing operations in ext-tile
      when large-scale-tile is on and off. This fixes an enc/dec mismatch
      issue when both ext-tile and obu are turned on.

      Fix ext-tile and obu · 5737b4c0
      Jingning Han authored
      Fix the broken unit test when ext-tile and obu are both turned on.
      The test failure was due to the merge of CONFIG_ADD_4BYTES_OBUSIZE.
      This solves the unit test failure cases when cm->large_scale_tile
      is on.

      Zoe Liu authored
      The removed variable was once defined for evaluating the use of
      distance-weighted compound prediction for the new skip mode, under
      the scenario when all reference frames are forward predicted.

      Dake He authored
      Use a lookup table to deterimine speed of adaptation in update_cdf.
      Tests on 5 keyframes show improvement in BD-rate: consistently more
      than -0.2% for google test sets (lowres, midres, hdres).

      [lv_map_multi] multisymbol coding of eob · 0db7d0eb
      Dake He authored
      1. code the range of eob in a transform block as a single symbol.
      2. initialize cdfs directly.
      3. initial cdfs are trained by using laplace prob estimates as in base
      level coding (CL 38638)
