installiere minidlna (nach https://wiki.ubuntuusers.de/ReadyMedia/)
sudo apt-get install minidlna
setze interface z.B. wlo1
network_interface=wlo1 friendly_name=Laptop inotify=yes media_dir=V,/var/lib/minidlna/videos media_dir=A,/var/lib/minidlna/music
kopiere Zeug in /var/lib/minidlna
gib Rechte 644 auf die Dateien
find /var/lib/minidlna/videos -type f -exec chmod 0644 {} \;
restart server
Final Fix
Edit /etc/default/minidlna
to contain (and also /lib/systemd/system/minidlna.service)
USER=simon
GROUP=simon
Then /etc/minidlna.conf
to contain
user=simon
I also had to change permissions to allow my user
sudo chown simon:simon /var/cache/minidlna
sudo chown simon:simon /run/minidlna
Then restart the service
sudo service minidlna restart
sudo service minidlna force-reload
