I am using Plex package on my Synology DS918+ for a long time now with a paying plex pass. I wanted to find an open source alternative which provides me a some features like user management, a decent mobile client, controlled access to library, etc...

Jellyfin Demo

Jellyfin seems to provide all what I need. I installed it on my NAS using the regular docker image, proxied via synology application portal and a Let's encrypt certificate.

Installation procedure is here and I just had to modify the docker instructions to fit my needs and point the media folder on my NAS.

docker run -d \
 --volume /path/to/config:/config \
 --volume /path/to/cache:/cache \
 --volume /path/to/media:/media \
 --user 1000:1000 \
 --net=host \
 --restart=unless-stopped \
 jellyfin/jellyfin

Really easy to implement, Jellyfin provides the functions I wanted, I need now to experiment the mobile applications, as far as I can see the android client works well but sometimes it freezes when I put it on pause or change content.

I will probably soon cancel my plex pass subscription ;-)
