Subject Re: upnp media server pure java
Date Sun, 05 Oct 2008 21:00:16 GMT
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 ?
