minidlna

sudo apt show minidlna

Description: lightweight DLNA/UPnP-AV server targeted at embedded systems MiniDLNA (aka ReadyDLNA) is server software with the aim of being fully compliant with DLNA/UPnP-AV clients.

The minidlna daemon serves media files (music, pictures, and video) to clients on your network. Example clients include applications such as totem and xbmc, and devices such as portable media players, smartphones, and televisions.

MiniDLNA is a simple, lightweight alternative to mediatomb, but has fewer features. It does not have a web interface for administration and must be configured by editing a text file.

instalación y configuración de minidlna

sudo apt install minidlna

sudo nano /etc/minidlna.conf

# Specify the user name or uid to run as.
user=minidlna

# Path to the directory you want scanned for media files.
media_dir=A,/media/audio
media_dir=V,/media/video

# Port number for HTTP traffic.
port=9751

# Name that the DLNA server presents to clients.
friendly_name=RB3-DLNA

# Automatic discovery of new files in the media_dir directory.
inotify=yes

# List of file names to look for when searching for album art.
album_art_names=portada.jpg/contra.jpg

# Always set SortCriteria to this value, regardless of the SortCriteria
# passed by the client
force_sort_criteria=+upnp:class,+upnp:originalTrackNumber

donde la A de media_dir vale para restringir el directorio /media/audio para archivos de audio y la V, en el caso de /media/video, para video.

el usuario minidlna

el usuario minidlna debe tener permiso para acceder a los directorios declarados en media_dir. en los casos de /media/audio y /media/video, el usuario y el grupo son ernesto:ernesto.

sudo adduser minidlna ernesto

Añadiendo al usuario ‘minidlna’ al grupo ‘ernesto’…
