A partir de aquí nos encontramos con sistemas como el que ofrece LG o Samsung en sus Smart TV, (así como muchísimas más compañías), el sistema de compartición de contenidos DLNA (Digital Living Network Alliance) basado en parte, en el protocolo UPnP que nos permite hacer streaming vía wifi en nuestra red doméstica de aquellos contenidos multimedia almacenados en el pc, tablet o el móvil, hacia la TV.
Instalarlo:
sudo apt-get install minidlna
Sólo hay que configurar el archivo /etc/minidlna.conf
# port for HTTP (descriptions, SOAP, media transfer) traffic
port=8200
# network interfaces to serve, comma delimited
#network_interface=eth0
# set this to the directory you want scanned.
# * if have multiple directories, you can have multiple media_dir= lines
# * if you want to restrict a media_dir to a specific content type, you
# can prepend the type, followed by a comma, to the directory:
# + "A" for audio (eg. media_dir=A,/home/jmaggard/Music)
# + "V" for video (eg. media_dir=V,/home/jmaggard/Videos)
# + "P" for images (eg. media_dir=P,/home/jmaggard/Pictures)
# Use A, P, and V to restrict media 'type' in directory
media_dir=A,/media/compartida/Musica
media_dir=P,/media/compartida/Imagen
media_dir=V,/media/compartida/Videos
# set this if you want to customize the name that shows up on your clients
friendly_name=LinuxServer
# set this if you would like to specify the directory where you want MiniDLNA to store its database and album art cache
db_dir=/var/cache/minidlna
# set this if you would like to specify the directory where you want MiniDLNA to store its log file
log_dir=/var/log
# set this to change the verbosity of the information that is logged
# each section can use a different level: off, fatal, error, warn, info, or debug
#log_level=general,artwork,database,inotify,scanner,metadata,http,ssdp,tivo=warn
# this should be a list of file names to check for when searching for album art
# note: names should be delimited with a forward slash ("/")
album_art_names=Cover.jpg/cover.jpg/AlbumArtSmall.jpg/albumartsmall.jpg/AlbumArt.jpg/albumart.jpg/Album.jpg/album.jpg/Folder.jpg/folder.jpg/Thumb.jpg/thumb.jpg
# set this to no to disable inotify monitoring to automatically discover new files
# note: the default is yes
inotify=yes
# set this to yes to enable support for streaming .jpg and .mp3 files to a TiVo supporting HMO
enable_tivo=no
# set this to strictly adhere to DLNA standards.
# * This will allow server-side downscaling of very large JPEG images,
# which may hurt JPEG serving performance on (at least) Sony DLNA products.
strict_dlna=no
# default presentation url is http address on port 80
#presentation_url=http://www.mylan/index.php

# notify interval in seconds. default is 895 seconds.
notify_interval=900
# serial and model number the daemon will report to clients
# in its XML description
serial=12345678
model_number=1
# specify the path to the MiniSSDPd socket
#minissdpdsocket=/var/run/minissdpd.sock
# use different container as root of the tree
# possible values:
# + "." - use standard container (this is the default)
# + "B" - "Browse Directory"
# + "M" - "Music"
# + "V" - "Video"
# + "P" - "Pictures"
# if you specify "B" and client device is audio-only then "Music/Folders" will be used as root
#root_container=.
Sólo debemos tener cuidado a nivel de permisos con las carpetas y todo debería funcionar sin problemas. Para arrancarlo como servició, tenemos un script que deberíamos añadir y que lo obtenemos de la misma página del proyecto.

Con esta versión además incluimos la opción de consulta de estado o status.
Para añadirlo manualmente como servicio, sólo debemos incluirlo en /etc/init.d/ y darle permisos.
sudo chmod a+x /etc/init.d/minidlna
Ahora hacemos que se funcione en los diferentes niveles de ejecución:
sudo update-rc.d minidlna defaults
La linea anterior también podría contener enable | disable | remove, para activar, desactivar o eliminar dicha ejecución del servicio.
Para activar el servidor utilizaremos:
sudo service minidlna start
Siendo stop | restart | status otras de las opciones disponibles.
Y por último para actualizar la base de datos de contenidos, al añadir nuevos elementos multimedia:
sudo /usr/sbin/minidlna -f /etc/minidlna.conf -R -d
