Fast Image & Video Fidelity Metrics in C, Zig

https://github.com/gianni-rosato/oavif appears to use this for quality-guided AVIF encoding.

I’m curious about a good comparison of how oavif compares with libjxl when one wants high fidelity with very good assurance that the result is going to retain high fidelity.

(I use libjxl to encode my photos, because I want a configure-once-then-trust batch operation that I can trust not to show artifacts but still compresses well both for SDR and HDR. The tunables of libjxl offer this directly while I couldn’t figure out (within my time box) a correlation between avifenc settings and what I can expect of the outcome.)
