    Maybe i'm blind but i can't find a simple example how to connect to a UPnP server.
    All i'm looking for is a code to list all songs in it's library. Later on i want to stream a song. But for the moment i would be happy to see code to connect to a server and simply list all songs. Or is that way harder than i think at the moment?

    Java preferred, but any other language would do.

    There are two different UPNP devices. One is a content server and the other something else, I don't remember - see the upnp A/V specification.

    Anyways, here's some very messy test code of mine, in Scala and Java - look at the bottom. It basically finds a TVersity server in my home network and starts browsing its content.


    Sorry about the mess - I left it in testing stage and I don't know when I'll come back to it.

    I looked at it and remembered what's going on. The relevant piece of code is this:

    def Browse(ObjectId: String , BrowseFlag:String, StartingIndex:String, RequestedCount:String) = {
          val directory = actual.services.filter (_.serviceType == "urn:schemas-upnp-org:service:ContentDirectory:1").head
          val action = directory.actions.filter (_.name == "Browse").head
          action.inArgs.setAttr("ObjectID", ObjectId, "BrowseFlag", BrowseFlag, "StartingIndex", StartingIndex, "RequestedCount", RequestedCount)  
          val aa = action.outArgs

    in the device, you'll find services and they have actions - all from cyber link's library - I had some Scala wrappers to make it easy. Find the "Browse" action and just invoke it…

    Didn't know Scala until now :]

    This code is perfectly what i was looking for! Thanks! Works like a charm.

    Now i only have to find out why my XBMC just shows a empty library (Does the same in all other UPnP controlpoints except the XBMC remote).

    Thanks a lot!

    Connection & Browsing works perfectly now!
    Anyone a tutorial how to get streaming kicking in? I just need audio streaming. Do i need to set up my own MediaRenderer Device for that or is it possible without (i don't need to remote remote control it etc.)?
