Also, Jellyfin supports LDAP backing, so OP could set up PocketID with an LLDAP backing server (minor extra complexity). Managing passwords will still be a chore as PocketID does not support neither setting them up nor syncing it with LDAP (it can read and authenticate LDAP users, not write them), but then Jellyfin can work without the OIDC plugin, just using the LDAP login approach.

well the crack is only supposed to affect the license checking.
but if you want an alternative, MOS is shaping up pretty well.
