Jellyfim MPV Shim direct path

[Nachtigaller]

I have the following problem: My server, which is also the client, is too weak to play a movie without stuttering. So I googled a bit and there seem to be two solutions to this problem being using either Kodi with the Jellyfin add on or Jellyfin MPV Shim. As Kodi has problems with my library structure I looked into MPV Shim and while it looked promising I couldn't get the direct path option to work resulting in insufficient performance.
So my question is if anyone of you got it working and if it is even possible with the current version of the Jellyfin server.
