GPUs for transcode in PLEX

[CosmicJoker42]

What GPUs will have support for hardware acceleration for things like transcode in PLEX?

I have an Intel A380 that I got for cheap that I'd like to use.

[MikeH13]

Did exactly them same and would love to know if this will work!

[Vroar]

interested in this aswell

[reagan]

I wanna know if old GPUs could cause issues, I have a 970 I scavenged from the landfill i'd like to use...

I wonder if it is working out?

[RB0]

If I receive my invite before this has been answered I will be happy to report back. I have the same GPU. 🤞

[I_BL00dy]

I  also want to know  the answer to this question. I have a buddy with a GTX 1070 that could become obsolete if he upgrades. having CUDA support for old GPUs could be handy.

I have a 1070 installed and it doesn't seem to work with Plex right now. I click enabled in TrueNAS scale under the Plex App and get this error

I got the same error when trying to use a 1050ti.

[Jackington]

Getting the same error when using nVidia Quadro K620.

Hardware acceleration enabled in Plex.
iGPU disabled in BIOS.
Enabling GPU in Plex settings in TrueNAS gives 'Failed to render compose templates' error.
Have selected 'Install nVidia drivers' in TrueNAS config and the update downloaded the drivers.

Takes 5-10 minutes to buffer 10 seconds of 4K video so definitely not using GPU for transcode.

[Mascot]

I came across some threads that might be relevant to this while I was trying to figure out a different issue I was having with transcoding. I didn't keep those links, but did a search now and try this thread in the Truenas forums, perhaps it would be helpful.

[Herbie4206]

let me know if you guys get this going.

The Alchemist cards should work great. Battlemage will have to wait until the kernel in TrueNAS (and then HexOS) is updated to support it.  I was going to use a B580 with Jellyfin, but from what I read about the TrueNAS Scale roadmap, i't'll be late Spring before it's fully supported in HexOS.

[tovy14]

I can confirm that I have just tested kernel 6.12 with Fangtooth 25.04 and golden 25.10, of course very earlier releases. Intel arc b570.

The drivers still seem to be missing and I cannot pass-through the gpus

[Master-spud]

I do have an intel A380 working with Plex, I ended up having to do the plex install in Truenas  instead of Hexos and fight for a bit... but was able to get HW decoding going.

What did you do get it going and did you check the plex logs to ensure it actually is working rather than appearing like it is, but in actuality falling back to the cpu for transcoding?

[Dylan]

Hey folks. Just want to share the the HexOS team is aware of the IntelARC GPU passthrough issue and has a test system being used to try and ID and diag/resolve the issue.

Thank you for your patience.

[Master-spud]

Honestly wish I was more help, new to this whole hexos/truenas thing... it is 100% working, plex shows HW in the dashboard when transcoding and CPU usage doesn't jump with 6 transcoded 4k streams going. 

 

As to what I did... I tried installing plex through Hexos, which made the folders and stuff for me, but transcoding didn't work despite showing the GPU, ended up uninstalling plex, and reinstalling via truenas using the default save paths that Hexos did, that also didn't work. I then uninstalled again and installed using truenas default install paths, and just adding the paths for my movie storage. Then the transcoding started working fine. I'm sure it's some permission issue in the background somewhere, but I couldn't figure it out but this worked for me. Your mileage may very lol

Hey - Wanted to say I also have a IntelARC gpu for transcoding that is not playing nice with the HexOS Install.


Willing to help figure this out / test things however is needed. Just hit me up!

Model: https://www.asrock.com/Graphics-Card/Intel/Intel Arc A310 Low Profile 4GB/
CPU: Ryzen 3950x (No onboard graphics)
Board: https://www.gigabyte.com/in/Motherboard/X570-AORUS-ELITE-WIFI-rev-1x/sp#sp


Enabled the "Passthrough non-nvidia GPU"  option, and Plex can see the GPU, but will not use it. 



Plex Dashboard showing transcoding happening but no (hw) next to Transcode - meaning CPU transcoding is happening.
