Hardware transcoding: Plex is working, Jellyfin not workig

[nicoska84]

Hi,
I installed from fresh both Plex and Jellyfin. With Plex I'm able to use hardware transcoding without any issue.
With Jellyfin, even if I choose "hardware transcoding" in the Dashboard I still see huge CPU cores usage.

Do you know what could it be?
Thank you
Nico

Some tools to help

apt-get -y install {vainfo,intel-gpu-tools}

command vainfo
command intel_gpu_top

vainfo output:

intel_gpu_top (lunched when playing something on Jellyfin):

[nicoska84]

So, after updating to latest Proxmox Kernel, here is the situation (playing the same file, transcoded at the same quality):

Plex LXC (~1% cpu)

Jellyfin LXC (~15% cpu)

Container got the same numbers of cores and RAM.

Pretty strange, maybe Plex transcoder is better?

[tteck]

Plex for the win, for sure.

The last thing is to try Tdarr and see

[nicoska84]

Nope, Tdarr is not converting using GPU :/

With this solution, seems to work: #1765 (reply in thread)
But CPU usage is increasing anyway.
