Verifying iGPU Acceleration on TrueNAS

[mindf0rk]

Hello friendly folks,

I was wondering whether someone here could give me a hint in the right direction.

My TrueNAS Scale NAS runs the latest jellyfin Release as an 'App' (=Docker container). I do believe that Intel UHD 620 Acceleration might work, b/c the accessible jellyfin-ffmpeg logs on the Jellyfin web interface do not output any errors, and state

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -analyzeduration 200M -ss 00:04:06.000 -init_hw_device vaapi=va:,kernel_driver=i915,driver=iHD -init_hw_device qsv=qs@va -filter_hw_device qs

When transcoding say a 4K UHD 120 Hz webm to HEVC, my i5-8400 CPU load sits at around 75% on all cores according to the TrueNAS Dashboard (which, you guessed it, won't show GPU cores). I'm thinking a little on the high side, but I do not know what it should be in this configuration.

Anyway, I'd like to verify, but have no exact idea how to. The docker container shell does not seem to run with a sudoer user, and I'd rather not mess around with it on my own.

Help is much appreciated!

There have been quite a few people here that couldn't get transcoding to work with the "App" version in the TrueNAS store. They switched to a vanilla docker setup using our official docker image and it transcoded as expected.

If possible, could you switch to a plain docker setup?

Thanks for the quick reply! Yes, I believe I could do so ... maybe first to try and compare the two if I get HWA working in a plain setup?
However, it would be mighty convenient if I could ultimately keep the "App" version.

Can you share the ffmpeg log from the transcode you mentioned in the first post?

[mindf0rk]

Certainly!

The transcode looks right. I'd definitely switch to a vanilla docker setup with our official image. You're not the first person to have this kind of problem. Another user couldn't even get direct play to work on the TrueNAS "App" for Jellyfin.

I‘ll definitely give it a shot when I find the time. Direct play works atm though.

Thanks for your time!
