      Mark AOM_QM matricies const. · 90243cf9
      Ralph Giles authored
      These large (200 KB) static stables are functionally read-only. Marking
      them const moves them to the read-only section of shared libraries,
      reducing memory footprint when multiple application processes are
      running simultaneously.

      Remove 4:4:0 source videos · 7d56ad44
      Yaowu Xu authored
      4:4:0 has been removed from AV1 profiles, therefore there is no need
      to have these files for testing.

      Turn on ref-adapt by default · 7736239d
      Zoe Liu authored
      This experiment of ref-adapt removes the option of COMPOUND_REFERENCE
      from the frame level reference_mode setup, and hence removes 1 bit
      in the frame header syntax. It now allows only SINGLE_REFERENCE or
      REFERENCE_MODE_SELECT to specify in the frame header.
      No noticeable coding performance impact has been observed.

      Previously the v component assignment was being skipped.
      This will make a difference with the EXT_QM experiment.

      added to the rtcd file and were not getting called.

      Turn on frame_sign_bias by default. · d4f22f45
      Zoe Liu authored
      This experiment of frame_sign_bias is to remove the 7 bits in the
      frame header that signal the sign bias value for the 7 reference
      frames. Instead of explicit signaling, this experiment is to use
      the frame_offset value to derive the frame sign bias. It achieves
      -0.08~-0.1% coding gain on average. It has been adopted by AOM.

      fix bug to use b_quantizer when trellis quantization is disabled. · 5b8c5fdc
      Ryan authored
      when trellis quantizaiton is disabled, the b_quantizer should be used.
      existing code has a lot of hard coded flag not hooked up correctly with
      high level trellis quantization enable/disable flag, which causes
      fp_quantizer is used. this patch is intended to remove the hard coded
      flags and correctly get them from the high level control.

      Refactor base range decoding to avoid hard division · 51fac92a
      Jingning Han authored
      Use cumulative range check to avoid the division in the for-loop
      for base range decoding in lv-map. This makes the lv-map transform
      coefficient decoding process 10% faster at the decoder end, at
      high target bit-rate range.

      Drop repeated tx size search from intra mode txfm RD · 6217782f
      Jingning Han authored
      When the coding block size is below 16x16, the current tx size
      search loop may end up searching 4x4 transform size multiple times.
      This commit skips the redundant search steps. Tested a a few
      1080p clips at 4 Mbps, the encoding speed is up by 10% for key
      frame coding, and 3% for overall.
