SOLVED: Startup with Hardware Accelleration

[AlexDausF]

Hi there,

I tried to set up Hardware Accelleration in my Jellyfin running in an Docker container. I used the How To here:
https://jellyfin.org/docs/general/post-i...ualization
It started up right but it could not open movies and I could not access the Administration / Playback/ Transcoding Area.
When I wanted to start a movie the player quit telling me it run into an issue. I have included the error output.

How can I proceed and try again?

Thanks for any help!
Alex
