# This is the configuration file for the MiniDLNA daemon, a DLNA/UPnP-AV media
# server.
#
# Unless otherwise noted, the commented out options show their default value.
#
# On Debian, you can also refer to the minidlna.conf(5) man page for
# documentation about this file.

# Specify the user name or uid to run as (root by default).
# On Debian system command line option (from /etc/default/minidlna) overrides this.

# Path to the directory you want scanned for media files.
#
# This option can be specified more than once if you want multiple directories
# scanned.
#
# If you want to restrict a media_dir to a specific content type, you can
# prepend the directory name with a letter representing the type (A, P or V),
# followed by a comma, as so:
#   * "A" for audio    (eg. media_dir=A,/var/lib/minidlna/music)
#   * "P" for pictures (eg. media_dir=P,/var/lib/minidlna/pictures)
#   * "V" for video    (eg. media_dir=V,/var/lib/minidlna/videos)
#   * "PV" for pictures and video (eg. media_dir=PV,/var/lib/minidlna/digital_camera)

# Type and minimum level of importance of messages to be logged.
#
# The types are "artwork", "database", "general", "http", "inotify",
# "metadata", "scanner", "ssdp" and "tivo".
#
# The levels are "off", "fatal", "error", "warn", "info" or "debug".
# "off" turns of logging entirely, "fatal" is the highest level of importance
# and "debug" the lowest.
#
# The types are comma-separated, followed by an equal sign ("="), followed by a

#   * "V" - "Video"
#   * Or, you can specify the ObjectID of your desired root container

# If you specify "B" and the client device is audio-only then "Music/Folders"

SYNOPSIS
     minidlnad [-f config_file] [-d] [-v] [-u user] [-i interface] [-p port] [-s serial] [-m model_number] [-t notify_interval] [-P pid_filename]
               [-w url] [-S] [-L] [-R]

     minidlnad [-h | -V]

DESCRIPTION
     The minidlnad daemon is a DLNA/UPnP-AV server sharing media files (video, music and pictures) to clients on your network. Clients are typically
     multimedia players such as vlc, totem and xbmc, and devices such as portable media players, smartphones, televisions, video game entertainment sys‐
     tems and blu-ray players.

     By default, minidlnad listens on all the network interfaces (except loopback) for clients. This behavior can be changed on the command-line using
     the -i option, or in the configuration file through the network_interface option (see minidlna.conf(5) for details).

OPTIONS
     Most of the options below can also be set in a configuration file, as described in minidlna.conf(5).

     -d      Activate debug mode (do not daemonize).

     -f config_file
             Specify the location of the configuration file. Uses /etc/minidlna.conf by default.

     -h      Show help and exit.

     -i interface
             Network interface to listen on. Can be specified more than once.

     -L      Do not create playlists.

     -m model_number
             Model number the daemon will report to clients in its XML description.

     -P pid_filename
             PID file to use; the default is /run/minidlna/minidlna.pid.

     -p port
             Port number to listen on.

     -R      Forces a full rescan of the media files. First it will remove all cached data and database. Any bookmarks will be lost.

     -r      Do a non-destructive rescan of the media files on start-up.

     -S      Stay foreground. Can be used when minidlnad is being managed by systemd

     -s serial
             Serial number the daemon will report to clients in its XML description.

     -t notify_interval
             Notify interval, in seconds; defaults to 895 seconds.

     -u user
             Specify which user minidlnad should run as, instead of root; user can either be a numerical UID or a user name.

     -V      Show the program version and exit.

     -v      Verbose output.

     -w url  Sets the presentation url; the default is http address.

FILES
     /etc/minidlna.conf
             Default system-wide configuration file. See minidlna.conf(5) for details on the syntax.
