Hi,

The updated PSNR values look really good (and the max difference going
from 1 to 0), but unfortunately I lack the capacity to verify that the
code is doing the same thing as the original thing.

Can we please have someone's eyes on this? If a patchwork URL makes it
simpler, it's https://patchwork.ffmpeg.org/patch/5440/ .
