Great :)

Yes. Call GetProtocolInfo on the Renderer's ConnectionManager service.
The sink variable of the response gives you a comma-separated list with
entries like http-get:*:audio/mpeg:DLNA.ORG_PN=MP3 or maybe a * at the
end as well, I think dLeyna even preprocesses that for you. The only
uncompressed format DLNA supports is raw PCM (profile LPCM), but there
should be devices doing flac as well.

Btw, to be really foolproof, all your uris should have a file extension
matching the file-type. Some (mainly cheap) devices rely on them.

Not really.

There was something as a demo of gupnp-php, but I've no idea how usable
that is or what it's called.
