Hardware acceleration on Synology DS224+

[The Bow-Tie Guy]

Thanks very much, but what didn´t work is the implementation with docker container to tell jellyfin what to do and to give it access to the gpu.... that´s what I was asking for in my first post.
When I now only activate quick sync and go with what the GeminiLake column says some videos won´t start.

So do I have to add this at any point to docker container?
services:
jellyfin:
image: jellyfin/jellyfin:10.8.11
container_name: jellyfin
# user: uid:gid
network_mode: 'host'
volumes:
- ./configconfig
- ./cachecache
- /volume1/Media/Filmemovies:ro
- /volume1/Media/TV Showstv_shows:ro
devices:
- /dev/dri/renderD128dev/dri/renderD128
- /dev/dri/card0dev/dri/card0
#note: uncomment these lines in devices to allow for HWA to work on Synology units with an iGPU
restart: 'unless-stopped'

Cause that was what didn´t work and it was frustrating cause I watched so many tutorials for that. Other question .... do I have to re-install everything to make work? Open a project in the docker container and then tell jellyfin what to do and give it access to the gpu. Oh when I tried I wasn´t able to open port 8096, what normally works automatically when you install jellyfin with adding those lines I posted above.

Thanks for the help!
