Jellyfin Family WHMCS module

WHMCS module that automates Jellyfin media-server accounts with a family / sub-account system. Sell Jellyfin access as a WHMCS product: each service maps to a main Jellyfin user whose library access, playback and transcoding policy, Live TV, SyncPlay, session limits and lockout are driven by the product configuration. On top of that, clients can create a configurable number of media accounts — additional Jellyfin sub-users, each with its own password, enabled state and library subset — and manage them, and their devices, from the client area over AJAX. Supports PHP 7.4 / 8.1 / 8.2+.
