Most older hardware has HEVC decoding but only the last few gens have AV1. My 10980XE is like 96% occupied while watching AV1 without HW acceleration so many smaller devices can't do anything resembling a smooth playback.

That seems high. What resolution and frame rate is the video? And which decoder are you using? dav1d is a highly optimized software decoder so that's the one to try:

https://code.videolan.org/videolan/dav1d/

It's used in Firefox, Chrome, ffmpeg, etc.


I tried it on some 8K HDR test video on YouTube on Linux/Firefox... All 18 cores and 36 threads at ~96%. NUC with an older Atom (7PJYH) gave like 0.1fps...


Which video and when did you try it? dav1d has improved a lot over time. You should try it again. You should also try any other AV1 video on YouTube. There's a lot of it there these days.

That shouldn't be the case. I play AV1 (via dav1d, software) w/o issue on much weaker CPUs than that (a zen1 laptop cpu and a haswell i7). The CPU is mostly idle.
