Transcoding on Truenas Scale on a N5095-based NAS

I am trying to get HW transcoding working using Truenas Scale 25.10.6 running on Celeron N5095 NAS (Terramaster F4-423) /w 32GB of RAM... which only has the JasperLake iGPU. Particularly for DV Profile 7 videos I am trying to play via a browser (Mac Safari)... Direct Streaming to supported clients works fine.

I am using the Truenas version community version of the Jellyfin Docker app (Jellyfin ver. 10.11.11 - App Ver. 1.3.12).

I followed the guide here:

https://jellyfin.org/docs/general/instal...d/truenas/

In the App Config under truenas I have passthrough set to enable for non-Nvidia GPUs.

Within Jellyfin I have the following set under Playback->Transcoding:

On thing I am unsure of, is how to enable Low-Power mode on the i915... it was mostly in relation to older kernels but Jasper Lake specifically needs some sort of Intel binaries installed, but I am not sure if these exist in Truenas Scale.

I have see some people mention needing specific GuC and HuC firmware, and a kernel parameter (i915.enable_guc=2 for Jasper Lake specifically) but that was on older Truenas Versions... not sure if that is still needed.
