Transcoding on truenas doesn't work

[Artik1]

Hello everyone,
I recently installed Jellyfin on my TrueNAS SCALE system and I'm having trouble getting hardware transcoding to work.
Here are my system specs:
CPU: Intel i3-6006U with integrated Intel HD 520 graphics
RAM: 8GB
Storage: 1.5TB HDD and 240GB SSD for boot
I've enabled hardware acceleration via the VA API and disabled transcoding/encoding of unsupported formats following the guidelines from the Intel Quick Sync Video Wikipedia page: https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video.
Despite this, I'm unable to get transcoding to function properly, whether in 4K or 1080p. In 1080p, I do get remuxing if the original bitrate is very low, but full transcoding just doesn't work.
Has anyone experienced similar issues or have any suggestions on how to resolve this? Any help would be greatly appreciated!Thank you!

Are you using the community app on Scale?

Which user and group are you running the container with?

Could you provide a screenshot of your VAAPI settings in Jellyfin just in case?

Also, for the GPU Resource dropdown, only allocate 1 GPU. You're allocating 5. Jellyfin only ever needs 1 allocated.

Hi! I'm sorry for the late reply, but i didn't receive any notifications ¯\_(ツ)_/¯
So, here are (some of) the answers:

Are you using the community app on Scale? - I installed the app through the appstore, it says community right next to Train, not sure if that's what you meant tho (I'll leave a GDrive photo folder at the end of the message)

Which user and group are you running the container with? - How can I check that?

Could you provide a screenshot of your VAAPI settings in Jellyfin just in case? - Sure, you'll find it in the GDrive folder

Also, for the GPU Resource dropdown, only allocate 1 GPU. You're allocating 5. Jellyfin only ever needs 1 allocated. - Oops, thank you for pointing that out. That's quite confusing though, because I only have the HD520 iGpu in my system OwO

Has anyone found a solution?

We still need ffmpeg logs and server logs and screenshots of Dashboard > Playback in the Jellyfin UI.

Hi! Thanks for your reply
The screenshots are in the GDrive folder: https://drive.google.com/drive/folders/1...sp=sharing
About the logs... Where can I find them?

[TheDreadPirate]

Ah. I didn't watch the video. Your iGPU doesn't support HEVC 10-bit decoding. It does support VC-1 and VP8 decoding, though.

Dashboard > Logs. Both the main jellyfin logs (filename starts with "log") and a ffmpeg log (filename starts with "FFmpeg").

Thanks, I changed my settings, and I uploaded my latest log to the folder Again, thank you for helping me!

P.s. From a brief look, the log is generated after trying to open the movie "Continuavano a chiamarlo Trinità" (Yes I'm Italian). The movie was just a basic 1080p file (I believe H264) and it had a very low bitrate, though it still failed 🤷🏻🤦🏻

Uncheck low power encoding.

[Artik1]

Done!
Also, should I check qsv or is vaapi fine?
