      SSE4 and AVX2 implementations of updated FAST_SGR · d051e560
      Imdad Sardharwalla authored
      The SSE4.1 and AVX2 implementations of the self-guided filter have been updated
      to match the updated FAST_SGR C implementation in restoration.c.
      
      The self-guided filter speed tests have been altered to compare the speeds of
      the SIMD and C implementations of the relevant functions.
      
      Speed Tests (code compiled with CLANG)
      ===========
      
      For LowBD:
      - The SSE4.1 implementation is ~220% faster (~69% less time) than the C code
      - The AVX2 implementation is ~314% faster (~76% less time) than the C code
      
      For HighBD:
      - The SSE4.1 implementation is ~240% faster (~71% less time) than the C code
      - The AVX2 implementation is ~343% faster (~77% less time) than the C code

      Reduce memory usage of inter_tx_size[] in MB_MODE_INFO · 7167d952
      Hui Su authored
      Reduce the length of inter_tx_size[] from 1024 to 16.
      
      On a cif test sequence,
      encoder memory consumption decreases by 18% (380MB -> 312MB);
      decoder memory consumption decreases by 56% (21.4MB -> 9.4MB).

      AVX2 implementation of the Wiener filter · aab6aee3
      Imdad Sardharwalla authored
      Added an AVX2 version of the Wiener filter, along with associated tests. Speed
      tests have been added for all implementations of the Wiener filter.

      Don't use extra lines for r=2 guided filter · f7d1ff49
      Debargha Mukherjee authored
      Changes the CONFIG_FAST_SGR=1 strategy to not use any
      subsampling for the r=1 filter, but for the r=2 filter
      sub-sample vertically but combine only by filtering
      horizontally in the last stage for odd rows.
      
      Coding efficiency loss sems quite minimal.

      Port first pass stats handling from Vp9 into Av1 · da01c0dc
      Debargha Mukherjee authored
      Some parameter tuning included.
      
      lowres (q, 30 frames, speed 1):
      -1.243% av PSNR, -2.337% ov PSNR, +0.577% SSIM
      
      lowres (vbr, 30 frames, speed 1):
      -0.327% av PSNR, -1.007% ov PSNR, +0.182% SSIM
      
      A few videos become a lot worse in SSIM, which needs to be
      investigated. But PSNR-wise the patch seems pretty good.

      Remove aom_comp_mask_upsampled_pred from rtcd · f8daa92d
      Peng Bin authored
      Since aom_comp_mask_upsampled_pred just call aom_upsampled_pred
      and aom_comp_mask_pred, no need to separate c version from simd
      version any more.

      Fix txk-sel unit test failure in aq-mode · 1e79d90e
      Jingning Han authored
      The current aq mode encoder setting would alter the segment_id
      between the rate-distortion optimization and the block encoding
      stages. Disable the corresponding consistency check in this case.
