Well we can't really guarantee the compliance. We assume it's matching
for files the have identified as such or our transcoded streams (apart
from WMV).

No, you can't really guess it if you don't know how URIs are generated.

And with this line, you'll never be able to find it. You need to add
"enable=true" to the [GstLaunch] section.

In general it's
http://ip:port/PluginName/i/SomeBase64EncodedStuff.extension

ip is the interface Rygel is bound to, port can either be configured in
rygel.conf or set via -p commandline parameter. "/i/" denotes an item
and the base64 stuff is plug-in specific and the extension optional

For GstLaunch it is the part before -launch, so in your case my.

Let's say you've started rygel with -p 12345 -n lo, you'd have something
like:

http://127.0.0.1:12345/GstLaunch/i/bXk= or
http://127.0.0.1:12345/GstLaunch/i/bXk=.mp3

Most of the time it's not possible to specify the filename.
