      Adjusting thresholds in mfqe post-processing · c6fd0a5d
      Deb Mukherjee authored
      Adjusts some of the qualification thresholds in mfqe to eliminate
      artifacts due to wrong decisions. Besides, a new qualification
      criteria is used to disable mfqe if the quality of the previous
      frame is itself not too good.

      Encoder denoiser performance improvement · 64075c9b
      Yunqing Wang authored
      The denoiser function was modified to reduce the computational
      complexity.
      
      1. The denoiser c function modification:
      The original implementation calculated pixel's filter_coefficient
      based on the pixel value difference between current raw frame and last
      denoised raw frame, and stored them in lookup tables. For each pixel c,
      find its coefficient using
          filter_coefficient[c] = LUT[abs_diff[c]];
      and then apply filtering operation for the pixel.
      
      The denoising filter costed about 12% of encoding time when it was
      turned on, and half of the time was spent on finding coefficients in
      lookup tables. In order to simplify the process, a short cut was taken.
      The pixel adjustments vs. pixel diff value were calculated ahead of time.
          adjustment = filtered_value - current_raw
                     = (filter_coefficient * diff + 128) >> 8
      
      The adjustment vs. diff curve becomes flat very quick when diff increases.
      This allowed us to use only several levels to get a close approximation
      of the curve. Following the denoiser algorithm, the adjustments are
      further modified according to how big the motion magnitude is.
      
      2. The sse2 function was rewritten.
      
      This change made denoiser filter function 3x faster, and improved the
      encoder performance by 7% ~ 10% with the denoiser on.

      msvs/tests: fix data alignment for asm tests · 10f8b361
      James Zern authored
      Replace DECLARE_ALIGNED_ with vpx_memalign()
      
      DECLARE_ALIGNED (__declspec(align())) does not work as intended when
      used on class data members:
      
      Data in classes or structures is aligned within the class or structure
      at the minimum of its natural alignment and the current packing setting
      (from #pragma pack or the /Zp compiler option)

      Parse out arm isa targets from dumpmachine · 2b59e14a
      Mike Frysinger authored
      The current parsing logic of the dumpmachine tuple lacks any arm
      cases which means tgt_isa never gets set, so for all arm targets,
      we get detected as generic-gnu.  Add some basic arm checks here
      so the automatic detection logic works.

      do not error out on generic-gnu + --enable-shared · b4ab43f1
      Mike Frysinger authored
      If you build with --enabled-shared on a Linux arch not explicitly
      listed, the configure script will abort because it didn't detect
      "linux" in the fallback generic-gnu tuple.
      
      Since this is the fallback tuple and people are passing
      --enable-shared, assume the user knows what they're in for.
