How to extract tags from a stream without playing it?

[Phong Cao]

Thank you Arun,

I decided to try out the GstDiscoverer. I already included necessary header.
However, it ould not be compiled:

g++ -g /home/phongcao/C/dingo-draft.cc -o /home/phongcao/C/dingo-draft
`pkg-config --cflags --libs gtk+-2.0 gstreamer-0.10`

/home/phongcao/C/dingo-draft.cc: In function ‘void
import_media_activated(GtkMenuItem*, GtkListStore*)’:
/home/phongcao/C/dingo-draft.cc:57: error: ‘GstDiscoverer’ was not declared
in this scope
/home/phongcao/C/dingo-draft.cc:57: error: ‘discoverer’ was not declared in
this scope
/home/phongcao/C/dingo-draft.cc:57: error: ‘gst_discoverer_new’ was not
declared in this scope
/home/phongcao/C/dingo-draft.cc:59: error: ‘gst_discoverer_discover_uri’ was
not declared in this scope
/home/phongcao/C/dingo-draft.cc:59: error: ‘gst_discoverer_info_get_tags’
was not declared in this scope

Is there anything wrong with the way I compile the source with
GstDiscoverer?
