AV1 playback in LibreELEC on a Pi 4 (lemmy.ml)

I installed LibreELEC on a Raspberry Pi 4 yesterday and it's working really well, except for AV1 playback. The thing is, it's almost fast enough but the video stutters every few seconds and is a little slower than it should be. Is there a way to make it faster, by switching the decoder or enabling multi-core decode or something like that?

I found this decoder which might be what I'm searching for but I don't know how to make it work in LibreELEC.

Get active cooling as this kinda sounds like thermal throttling.

I added a 40mm Noctua fan blowing on the heatsinks of my pi3 to get it to play h265, otherwise I'd keep having issues like what you're describing.

That's probably the cheapest option. I already have it overclocked and it's running at about 82-83°C (But at 85°C it resets to the base clock so maybe the overclock isn't even being used). Adding active cooling might also allow me to overclock it further.
