 |
|
Hi All,
I've started experimenting to get DLNA and UPnP going, as far as i know the protocols are closely related, other than that i'm quite unfamiliar with these protocols. Reason is that i expect to be buying equipment which requires this to be able to do what i want to do with it. My end goal has two objectives: Publish a http audio output stream created by mpd, and allow browsing/playing of files in my music collection.
I've started experimenting on my desktop to eliminate any other networking issues, there is no local firewall configured.
So far i'm using VLC as a client, after enabling the zeroconf USE flag it shows "Zeroconf network sercvices" in the playlist. Enabling zeroconf also pulled in avahi, and after starting that daemon VLC started listing some local configured services (ssh and sftp). Of course VLC can't use those, but it seems to confirm that VLC and avahi are working together. On the network i see UDP multicast packets to port 5353 which is DNS-SD.
As a server i've tested with gerbera and minidlnad, both available in ::gentoo. Both seem to be working, but they don't show up in VLC as a possible source of data. When i look at the network traffic i see gerbera and minidlnad multicasting to UDP port 1900 (which is UPnP).
To me it seems like i'm missing a component to put it all together, is anyone able to help me with this?
Thanks in advance.

You may need to define a service in the /etc/avahi/services directory. It looks like for TCP DLNA I used this at one time:
| Code: | <?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<!-- See avahi.service(5) for more information about this configuration file -->
<service-group>
<name replace-wildcards="yes">%h</name>
<service>
<type>_dlna._tcp</type>
<port>8200</port>
</service>
</service-group> |
You may need one for your UDP service. Not sure which service name that VLC is looking for. |

How is your /etc/minidlna.conf:
| Code: | # port for HTTP (descriptions, SOAP, media transfer) traffic
port=8200
# network interfaces to serve, comma delimited (8 interfaces max)
network_interface=eth0
# specify the user account name or uid to run as
user=minidlna
# set this to the directory you want scanned.
# * if you want multiple directories, you can have multiple media_dir= lines
# * if you want to restrict a media_dir to specific content types, you
# can prepend the types, 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)
# + "PV" for pictures and video (eg. media_dir=PV,/home/jmaggard/digital_camera)
media_dir=/n/movies
media_dir=/n/music
media_dir=/n/music-video |
I don't use avahi, but my tv running vlc has no problem seeing the dlna server.

Thanks for your responses.

Do you mean my mpd audio stream? That's TCP based, so think it will be similar to your example.

As far as upnp, I have it disabled at the router for the lan and no problem.
minidlna probably tries upnp to see if the router will allow it.
Is vlc running on the same machine that the dlna servers are?
Edit to add: If you are trying to use upnp from vlc then did you enable upnp when you built vlc?
ETA2: Since you're using avahi (zeroconf use flag) is it set for both vlc and minidlna?
