No, this is not correct. Rygel only provides the stream. The command to
play has to be sent by an external controller such as GUPnP-AV-CP.

Also GNOME is not a precondition for running Rygel.

There's a modification for my tool korva/pushup which runs on the N9
that does what you describe, though [1]

No. More likely with plain GUPnP/GUPnP-AV and some C coding or dLeyna
and some python scripting as Rygel is not a client library and that's
what you need here.

You need to be aware that DLNA renderer need HTTP and are likely to be a
bit picky about the stream format you send them.
