      dump_ssim: Fix pixel aspect ratio calculation. · 0b5ce2f4
      Timothy B. Terriberry authored
      We check that info1.par_n*info2.par_d == info2.par_n*info1.par_d,
       but even if that check passes, it is possible for, e.g.,
       info1.par_n to be info2.par_n*1000 (if the denominator is
       similarly scaled).
      But then we were mixing info1.par_n with info2.par_d when computing
       the pixel aspect ratio.
      So even when both streams have the same ratio, the result would be
       off by a factor of 1000 (in this example).
      
      Instead, only use the PAR parameters from one stream, now that we
       have checked that they match.

      dump_ssim: Make aspect ratio mismatch an error. · 8f8e5007

      Upgrading it from a warning.
      
      We scale the Gaussian window according to the pixel aspect ratio in
       order to match the shape and size of the window used by the
       fixed-size test images in the original paper.
      If the streams do not have the same aspect ratio, then there is no
       correct thing to do.

      Fix CIEDE script for high bit depth · 682621b0
      Josh Holmer authored
      The Cr plane would not read in the correct data
      on high bit depth videos, causing an incorrect result.
      This commit fixes the input offset so the correct
      values are read.
