SOLVED: HW acceleration not working – M4 Mac Mini

[Erlend]

Hi! This Friday I got my M4 Mac Mini – and (among other things) I'm trying to get it to work as a media server. After being on Plex, I wanted to give Jellyfin a try. And setup has almost been perfectly smooth.

Everything works as expected, but I can't get HW acceleration to work.

I've followed the guide here, but when I do the test (running a video in a browser client, and taking down the bit rate) I get the "ffmpeg uses 600% CPU" thing. Any advice?

I'm not quite sure where I should start troubleshooting, heh. 

• I've tried to restart Jellyfin a couple of times.
  
• Also restarted the Mac running the server.
  
• And I've tried a couple of different media files.
  

I'll add an image of my settings as well. I won't claim to know what everything means – so maybe I've turned on (or off) something stupid? :P

Thanks!

You should disable allow AV1 encoding because that will burn your CPU as Apple has not released a chip supports hardware encoding of AV1 yet but only for decoding.

The hardware accelerated AV1 decoding is also still missing but I'm going to got my M4 Mac soon, and I expect that would land in next major version of jellyfin.

Thanks! I did that, and now it doesn't burn it quite as bad. 👍🏻 But will it then just not do anything when it wanted to do it with AV1?

And, like, what should it look like when it works (when streaming a regular movie, for instance)?

There are very very rare clients that only accepts AV1 as almost everyone supports H264. What you would see would be the clients do not support HEVC will use H264 instead.

You click on Window in the menu bar, and click CPU History. Most CPU usage should be on E Cores and P Cores are rarely used.

I see.

Thanks, I think it works now! Will pay attention to the next version. 👍🏻
