Title: UPnP Browse DirectChildren Problem
Post by: TomNKY on February 11, 2013, 03:34:01 pm

I'm in the middle of a UPnP application for Windows Phone 8, and I have functioning code working against a couple MediaServers. My JRiver Server ( my favorite ;-) responded right off with Discovery of Devices, Services, and the first call in to the ContentDirectory to get the Root shot back it's answer just fine.

<?xml version="1.0"?><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
  <s:Body>
    <u:Browse xmlns:u="urn:schemas-upnp-org:service:ContentDirectory:1">

      <StartingIndex>0</StartingIndex>
      <RequestedCount>0</RequestedCount>
      <SortCriteria></SortCriteria>
    </u:Browse>
  </s:Body>
</s:Envelope>

And got

<DIDL-Lite xmlns="urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/" xmlns:dlna="urn:schemas-dlna-org:device-1-0" xmlns:av="urn:schemas-sony-com:av" xmlns:pv="http://www.pv.com/pvns/">

  </container>
</DIDL-Lite>

Then I asked for the contents of Audio and & always get the contents of the root.

      <RequestedCount>3</RequestedCount>
      <SortCriteria></SortCriteria>
    </u:Browse>
  </s:Body>
</s:Envelope>

Any ideas? Oh by the way it is a MediaCenter 16. If that had a problem I guess I'll upgrade. I actually bought 17 but didn't get around to using it cause well I spent a savage year of massive tagging and didn't want to change my machines around the house.  Probably I really was avoiding redoing all the Theater views Gizmos, webplays etc.... my theater view is extensive !

Thanks in advance

Tom

Welcome.

No more changes will be made to MC16 or MC17, so please try MC18.

You must have WMCCompat enabled in Advanced options since the Container ID for Audio isn't 4, it's 1 in DLNA (4 in WMC).
Disable it.

Thank you so much Bob !

Last night I was reviewing many discussions about UPnP connectivity and it dawned on me that in all likelihood because the J River options are so extensive I might have some silly configuration that was meant for a different use. So I tried your suggestion and BAM! , it works just like I anticipated in code. You no doubt saved me many hours of wheel spinning  :D.

Now I can continue pushing my Lumia 920 down the road to becoming a full ControlPoint  on the LAN. I know all the 'Cloud Kids' out there have plenty of options, but for those of use with TBs of storage for media on servers at home ( or for someone like a wedding dj on the road with a portable server setup & travel WiFI ) it would be great to walk around controlling the party. I want more functionality than Gizmo or web interfaces. It would be great to walk into any LAN space , add/insert playlist items from multiple Servers ( mixed brand ). So I'm shooting for the lower commonality of UPnP. So my WP8 app will be for a nitch group but it's my nitch group !

Once more Thank you very much for your observation.
