You could have a look at the gst-device-monitor-1.0 command line tool,
and see what it does for e.g.

 gst-device-monitor-1.0 Video/Source

or

 gst-device-monitor-1.0 Video


Code is here:
http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/tools/gst-device-monitor.c

How well it will work on your system depends a bit on what you're
looking for, the API hasn't been implemented for all plugins yet, but it
should work on Linux with v4l2 and pulse at least.

 Cheers
