How to Specify QSV Device for Transcoding in Jellyfin on TrueNAS Scale with k3s?

[Efficient_Good_5784]

How are you passing in the GPUs?  Are you just passing in /dev/dri in its entirety?  If so, add renderD129 to the end of the pass-through path and it will only pass that device in.

Thank you for reply. But TrueNAS Web UI only allows to pass the GPU core numbers, not the render device path in the config page 😂

Due to how Linux works, Jellyfin cannot figure out which device is which GPU.

And as of right now, Truenas Scale's Kubernetes app implementation doesn't allow for specifying which GPU to use ONLY if you have multiple from the same brand (in your case, both the CPU and GPU are from Intel).
Your only choice right now is to either remove the GPU so you 100% know that the iGPU will be the one used, or switch the CPU to a different brand so you know the GPU will be used.

If you wait for the next major Truenas Scale update to drop later this year, the app section will be reworked to not use Kubernetes and instead use Docker and compose files. You should be able to specify which GPU device is used there.
