When you look at a media server, you will see the 2 services you mentioned: ConnectionManager and ContentDirectory as defined in the media server specification. In order to play media you will need to find another device which supports the AVTransport service. This has the play() and stop() actions.
The Xbox and PS3 can both access content stored on a device through the ConnectionManager and ContentDirectory services, but they do not provide any services themselves. In this context, they are both Digital Media Players and NOT Digital Media Renderers as defined by DLNA ( http://www.dlna.org/digital_living/devices/) On 05/10/2008 22:00, "Survivant 00" <[EMAIL PROTECTED]> wrote: thanks. That explain a lot. One remaining question. I look at Intel upnp spy. and I only see a ConnectionManager and a ContentDirectory. I can browse.. but I did it how the client send a START ou PLAY on a media. do you know a client that can browse and play content and log everything on disk ? 2008/10/5 Jackson, Bruce <[EMAIL PROTECTED]> Yes. Felix contains an implementation of the UPnP stack as per the OSGi specification. This supports all of the basic UPnP discovery and service interaction mechanisms. The standardized services are built on top of this, but its up to you to implement them. You need to download the UPnP specs for Media Server and Media Renderer from the UPnP forum web site, and then read the specs to se what a media server is expected to return to a client. The flow is in essence, simple. 1. A control point (which you or someone else must write) uses the actions defined in the Content Directory (browse and search) to locate an item of media. This media item has a property which is its URL, where it can be located and "streamed" from. 2. The control point then finds an AV Transport service. This again, has many public actions, the most important being things like play and stop. Simply, the play action takes the URL which was previously obtained from the Content Directory. 3. Once the control point calls the play() action, the AV Transport will start reading from the URL and playing the media. Hence, it is possible that the URL is not actually present in the Content Directory at all, and is certainly not specified by the UPnP transports.

I didn't see in the doc how the server respond to the client. I suppose that when the client will do PLAY it will send a action to the server, but how the srever send the data back ? and I didn't see the javadoc of the upnp packages. what is the Maven2 parameters to pass in the command line to generate the javadoc ? mvn xxxx ? I read the blog : http://membres-liglab.imag.fr/donsez/cours/exemplesosgi/tutorialosgi.htm#upnp but didn't find how the data was send between the application. ---------- Forwarded message ---------- From: Jackson, Bruce <[EMAIL PROTECTED] <http://[EMAIL PROTECTED]> > Date: 2008/10/5 Subject: Re: upnp media server pure java To: "dev@felix.apache.org <http://dev@felix.apache.org> " <dev@felix.apache.org <http://dev@felix.apache.org> >, "[EMAIL PROTECTED] <http://[EMAIL PROTECTED]> " <[EMAIL PROTECTED] <http://[EMAIL PROTECTED]> > Streaming isn't done by the UPnP library at all. All the Content directory does is to provide the rendering application with a URL. Where that points is entirely up to you, but would typically be to a servlet running in your media server application (probably using the OSGi http service). Whether the http service uses NIO is another question altogether and I've no idea about the default Jetty implementation shipped with Felix. But if you want to use NIO, then you can always write something yourself that does.
