With the fix,\nusing Overall PSNR, compared to the previous ext-refs RD performance\nbefore the bug fix, all against the baseline, the improvements are:\n\n\"ext-refs\" before fix: lowres -5.665%  midres: -4.833%\n\"ext-refs\" after fix:  lowres -5.776%  midres: -5.000%\nImprovement by the fix: lowres -0.111%  midres: -0.167%\n\nChange-Id: I2eceedf2d4046b169514e049fd01baaf0bbb50c6\n",
