Maybe I am wrong… But it definitely not Plug and Play as in Plex.
I “assume” correct selection is “Intel…” but then you need to select something else
Honestly, I started with intention to use Jellyfin, but tried Plex and it much more polished. I jumped wagon 2 weeks ago before they raised prices and got lifetime license with them…
In jellyfin configuration, I used Intel QuickSync, and in the field QSV Device I used “/dev/dri/renderD129”.
At first, I was not sure it was working because the CPU was hitting 13% when transcoding (I have setted 2 cores for jellyfin), but I’ve found out it’s probably because of audio transcoding and subtitles rendering, which uses CPU for this.
Now if I change the bitrate of the movie to a low value, in a few seconds the movies starts playing. I’ve tested with a 4K HDR movie. With HW transcode off, the movie takes too long to start, keeps loading all the time.
