HW transcoding on a i5-8500T

[debug]

I am failing to set up HW transcoding on my i5-8500T after spending hours on it.

Can you help find out where the issue is? 

In the Jellyfin transcoding UI i have selected Intel QuickSync and QSV device as /dev/dri/renderD128

I am attempting to play this file: https://4kmedia.org/lg-chess-hdr-demo/

Docker compose file below. GIDs selected appropriately given the system GIDs. Right now the file fails to play (just loads forever) and even other content fails to play.

The file seems to play after about 15 minutes of transcoding and even then it is supper choppy. I got this machine in the hopes that I can use this for Jellyfin transcoding and perhaps I did not make the right choice here.

I can transcode 3 concurrent files on a 7500T 1L HP mini pc so your 8500T is all good.
The difference is I am not using docker and have it installed on bare metal with Ubuntu 24.04 LTS
I am not sure how to help you with your issue but I just wanted to let you know the hardware is all good, so once you fix the config you're all set

Sounds great, thank you. I appreciate the data point.
