A310 Transcoding help - aeto - 2024-11-29
Hello Jellyfin forums,
I'm having issues with hardware transcoding on my Jellyfin server.
I've tried getting some help on Discord, but the people there couldn't really assist (they tried, but didn't have much experience with intel GPUs), so I thought I should try the forums.
Here is some info on my setup:
CPU: Intel 4790K
GPU: Intel A310
OS: Debian with backported kernel (6.11.5+bpo-amd64)
Jellyfin deployment: Docker, deployed with a compose YAML through Portainer (see my YAML at the end)
Jellyfin version: v10.10.3
What currently happens when HW transcoding is turned on is that my CPU no longer spikes in usage, but the GPU spikes, as seen when trying to play this 4K HEVC HDR10 video file:

After buffering for a bit, I get the following error:
Playback Error
A fatal error was encountered in the HLS stream.
This event creates, as far as I can tell, three log files. I assume these are three attempts to start the transcode.
Log 1: https://pastebin.com/sHA0AupU
Log 2: https://pastebin.com/W2RQi1HK
Log 3: https://pastebin.com/LWBfw5sH
When HWA transcoding is turned off, the movie starts buffering, and my CPU quickly hits 100% usage (which is expected since it's 10 years old). With lower-resolution movies, it will start playing eventually (e.g., 720p footage). So, I assume the issue is unrelated to permissions for my media files (all folders/files are owned by the same user:group mapped to the container).
Following are screenshots of my current test settings inside of Jellyfin:

I hope you can help me find a solution to my issue. I've been working on this for almost two weeks now, and I just want it to work. It's been using up a lot of my time and energy.
If you need any extra information, please feel free to ask.
Thank you in advance,

Just checking that this Debian host is not like a VM or LXC or something, right?
Can you share the output of this command?

Do you have "non-free" and "non-free-firmware" in your debian sources?
What is the output of this command?
Code:
sudo apt list --installed | grep firmwareIf you don't have any "non-free" listings here, read this forum post on how to add non-free sources.
https://forums.debian.net/viewtopic.php?t=159039
Then
Code:
sudo apt update ; sudo apt install firmware-linux-nonfreeReboot and check that you don't see these messages anymore.

1. bpo kernel does not include bpo firmware package (bookworm does not provide those you need trixie/sid repo)
2. ARC GPU does not officially support 4th Gen Core processors

I do have non-free packages activated.
Which btw has been the default setting since Debian 12 :)

Probably going for Ubuntu LTS in that case.
Or do you have any other concerns/recommendations for me? Personally not a huge fan of Canonical but if that the best option it's fine.
(2024-11-29, 06:24 AM)nyanmisaka Wrote: 2. ARC GPU does not officially support 4th Gen Core processorsThis is very disheartening to hear. I wanted to use arc because I wanted to work against ewaste and deemed it cost effective, as the CPU is outside of transcoding still more than capable enough for what I've thrown at it for far with all of the rest of services running. The A310 seemed like a good cheap option to increase the lifespan and feature set, for relatively cheap. Additionally I was planning on using a 7th gen LGA 2066 CPU at some point, which is still in a PC that is in need of an upgrade, but that platform also doesn't support ReBar.
I did some more research specifically on what is not supported here, and it seems to be ReBar mainly?
Realistically how much performance am I losing or am I missing something else here? On your Hardware Selection page you say around 10%, but on Reddit I found figures as high as 70%. Considering this is mainly just for my girlfriend and I with the occasional friend or family, I don't think more than 2 simultaneous trans codes is the case for me.
I also still have a GTX 980 Ti laying around (which was originally in that system) But energy and AV1 support concerns made me get the Arc.
So is my Hardware that I currently own just not recent enough for Jellyfin transcodes? Playing original files is more than okay.
I use an nvidia shield TV (2019) in my living room and my main issue is the bad subtitle support that Android apparently has (according to a good friend who does Anime Fan-Subs who has talked to a Plex developer, so my info may be wrong). This makes watching Anime with more advanced subtitles basically unusable. Which is why I wanted to be able to transcode in the first place.
Thanks so much for your help so far. Knowing Debian doesn't support Arc at least sheds light on why I've lost so much hair over this (and there is not that much left), and eliminates the search for now. Switching to a new OS is annoying, but since I run everything in docker it should be fairly easy to re-deploy.

RE: A310 Transcoding help - nyanmisaka - 2024-11-29
The good news is that it is detected by your motherboard and linux kernel. But due to the lack of ReBAR support, the speed will be greatly reduced in some scenarios.
You can also refer to the documentation and pull the firmware files directly from the linux repo.

So, it'll work, but I need to enable low power mode?
Am I understanding that correctly?
Should I still switch to Ubuntu LTS 24.04?
RE: A310 Transcoding help - TheDreadPirate - 2024-11-29
Low power encoding is mandatory for Arc, which the HuC and GuC firmware enable. Switching to Ubuntu 24.04 would make it a bit easier to use Arc since a new enough version is installed by default.
