I quibble with this post.
Here's the gist of the issue:
"Intel has disabled AVX-512 support on its recent Core processors.
Fortunately, the AMD users are in luck. AMD's Ryzen 9000-series CPUs feature a fully enabled AVX-512 FPU"

@tromo @tuxbot then why this article? worse: "the complexity of AVX-512 means that such optimizations are generally limited to specific applications and require specialized knowledge of low-level programming."
so anyway, if I really got serious and scaled up this might matter, but my limitations are in setting up the job. Since I do lots of small clips, I am always the limiting factor, slowing everything down.
They have not found a fix for this, and I refuse medication.

@tromo @tuxbot I used to compile my ffmpeg, and that would be a good experiment. I used to also compile liquidsoap, but I don't bother them lately, since now my specific problems are resolved well enough.

@tromo @tuxbot I could probably compile in the optimization, but why bother?
