Emby fails to load GPU

[mijo311]

Hi there, I'm having an issue with Emby not loading the GPU I have installed. I'm running the Emby Official app and Scale is seeing the GPU I have allocated through the setup process. My issue is Emby is not recognizing it and is giving me this error when I check Emby's Hardware Logs. I've run the nvidia-smi and it sees the card installed but no processes are being leveraged on it. I've attached the log that Emby has that shows the GPU is detected but is failing to load. Is this a driver issue, or something else? I've tried to change some things in my BIOS to fix it per some other threads, reinstalled the app, and poured through the forums for a few days now and can't seem to find a fix for my issue. Any help is greatly appreciated.

Have you tested using the GPU via Plex? I think that is more worn ground. If it works there you could then deduce that the issue is somewhere within the Emby app instead of some other system problem.

 

[mijo311]

I guess unfortunately for me, I don't have a Plex Pass so I'm unable to test that at the moment. But thanks for the idea. I'll look into that when I get some time shortly

 

[indivision]

You shouldn't need a Plex Pass to test that. Most of Plex works for free without the Pass.

 

[mijo311]

I was poking around in Plex, which I've never used before today, and I had very few options available to me after installing the app. When I googled Plex hardware encoding options, the page I found from Plex said it was available to those with a Plex Pass. I'll take another look shortly.

 

[mijo311]

I found the page, and it does say that the Plex Pass is required. This may be a more recent thing that was done, but it makes sense to me and is in line with how Emby has their Hardware Transcoding options. Short of doing a complete uninstall and reinstall of TrueNAS. I'm not sure what else I can try. It seems like the issue is that the emby app does not have permission to run the /dev/dri/renderD128 file. I'm not sure which user/group I would need to grant permissions to if this is the case. Is it a matter of running a chmod on the above mentioned file?

 

[indivision]

Hm. They must have changed it. I was using it without Plex Pass some months back.

I would actually suggest asking in the Emby forums. They created the original docker app I believe that the chart is based on. I am using Emby on Truenas, but don't have a GPU on the Truenas machine so not sure how exactly that works. They are fairly good about helping there. There seems to be some stuff people have to do when using the docker version to get a GPU to work, so, it could well be it's not all baked into the Truenas app either. Sounds like it is not from your description.

Emby has been super reliable for me once I got it all set up on Truenas, no issues at all. I use it for my library, but my biggest use is as a DVR.

indivision has a great idea there. If you can't test with Plex, then, try and find any other app that can use a GPU and test with it. Same idea. But I suspect there are some adjustments to be made to get the Emby app to work with GPU.

This part is pretty straight forward. There is a drop down for allocating GPU resources in the TrueNAS app options.

Yeah, I know, but I see mentions of having to set environment variables, loading some extra software, etc with Docker Emby and GPU. Really not sure what is needed. That is what I was referring to, sorry was not clear.

 

[indivision]

I'll test it out now. I might switch to Emby myself since Plex seems to be stingy.

 

[sfatula]

Hah, I just noticed he (the OP) already posted on the Emby forums!

 

[mijo311]

Yes, I posted to the Emby Forums shortly after trying plex with no luck. I've been trying to figure this out for about a week now. Everything else is working, file management, shares, cache and backups came right back from my QNAP install but I'm stuck in a holding pattern until I can hopefully get this resolved. Still no hits on the Emby Forums yet but I'm still searching and reading what I can, hoping something jumps out at me and triggers whatever chain of thought that will help me get this resolved. Thanks for the suggestions and help so far. I greatly appreciate it.

And I just discovered that Emby also requires a subscription to turn on hardware acceleration.

Stingy bastards are colluding!

Yes they are. I've been using emby, according to my premeire license since January 2021. Back then I believe I paid $25 for the lifetime perpetual license. Now they have the same pricing model as Plex.

 

[indivision]

It looks like Jellyfin is a free fork of Emby. It appears to support hardware acceleration.

The Emby Forums didn't shed any new light on the issue for me, sadly. After trying for another week I ended up just installing Ubuntu and creating the ZFS pools there. Got everything working pretty quickly and consistently.

 

[sretalla]

Just to be clear... the Plexpass version of Plex Media Server is needed to hardware transcode, but you don't need a plexpass to use that version (if you attach to it via the browser from the same LAN, you just can't take ownership of that server with any Plex IDs... otherwise, it then forces you to plex.tv and the plexpass thing kicks in)

Sorry to hear that. Yes, for sure works without docker/kubernetes. For me, don't need a GPU any more (so can sell it for more than I paid) as the cpu is fast enough to transcode anything for me in software, even 4k. I've seen people who were able to make it work, but looked like a lot of manual aggravation.

I ran on bare metal ubuntu for years just fine.

My Nvidia card has been "broken" in truenas for months now. I just figured out installed emby directly in debian (truenas host) fixes it, so I'm just living with that for now.
My gpu was showing Nvidia-smi everywhere but never showing up in the containers.

I just used the emby dpkg install from their site. Probably gonna have to move the emby bin and move the service since the /opt/ doesn't seem to come back after reboot, or it's a permissions thing, I've been restarting it manually every boot.
