Jellyfin

Jellyfin is a free and open-source multimedia application suite designed to organize, manage, and share digital media files to networked devices.

Installation

There are a few options for installation:

jellyfin^AUR — compile from stable version
jellyfin-bin^AUR — pre-built binary
jellyfin-git^AUR — compile from latest commit

Setup

Start/enable the jellyfin.service systemd unit. Upon starting for the first time, Jellyfin will create configuration and data directories at /var/lib/jellyfin/ by default.

To begin configuring Jellyfin, browse to http://localhost:8096/ and complete the initial wizard.

Note: Check if any firewall settings are obstructing connection to Jellyfin if issues arise at this point.

Configuration

Nginx reverse proxy

The below configuration describes a Nginx reverse proxy with a sample certificate. Be sure to modify the template to suit your own circumstances. See upstream documentation for more reverse proxy configuration examples.

Note: Uncomment and append URLs of external web resources to the Content-Security-Policy header to avoid missing functionality when accessing Jellyfin via the reverse proxy.

/etc/nginx/sites-available/domain.com.conf

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name DOMAIN_NAME;

    # use a variable to store the upstream proxy
    # in this example we are using a hostname which is resolved via DNS
    # (if you are not using DNS remove the resolver line and change the variable to point to an IP address e.g `set $jellyfin 127.0.0.1`)
    set $jellyfin jellyfin;
    resolver 127.0.0.1 valid=30;

CSS customization

Server administrators can modify Jellyfin's appearance via the custom CSS field on the web dashboard. Many sources offer portable blocks of CSS to change server typography, colors, and layout. Some examples include Ultrachromic and upstream documentation.
