Fair enough, I understand the concern here. I'm working on integrating
(specifically and only) the postfilter of the ref decoder into our
postfilter-less decoder so I have something to compare it to. Initial
results suggest there's indeed something different (as suggested
earlier by the change in difference in PSNR), so I'll submit a new,
adapted patch once I'm done figuring out what this postfilter is doing
differently than what I understood from the specsheet.
