Well if needed, don't hesitate to ask for help.

If interested and/or if you go with gupnp library, you might find an example
at the UPnP/DLNA browser I wrote for our MediaCenter:

That's 100% correct.
It's really the most tricky part, especially if you really deal and
comply with DLNA specs.
If you want to know a bit more about DLNA, here are a few lines I
wrote a couple years ago:

>From client side, it's much easier to handle as you don't have to be so strict.
An "intelligent" client should just receive whatever is sent to him
through HTTP/RTP and demux/decode it on the fly.
A "stupid" client (e.g. PS3) that really complies with DLNA specs will
treat and demux the file as it has been announced by the server (e.g.
server tells it's a 2-ch AAC while it's aactually 7-ch AAC and the
client will decode it as a 2-ch one).
