 167 The <a class="link" href="gst-plugins-base-libs-gstdiscoverer.html#GstDiscoverer"><span class="type">GstDiscoverer</span></a> is a utility object which allows to get as much
 168 information as possible from one or many URIs.
 169 </p>
 170 <p>
 171 It provides two APIs, allowing usage in blocking or non-blocking mode.
 172 </p>
 173 <p>
 174 The blocking mode just requires calling <a class="link" href="gst-plugins-base-libs-gstdiscoverer.html#gst-discoverer-discover-uri" title="gst_discoverer_discover_uri ()"><code class="function">gst_discoverer_discover_uri()</code></a>
 175 with the URI one wishes to discover.
 176 </p>
 177 <p>
 178 The non-blocking mode requires a running <a href="http://library.gnome.org/devel/glib/unstable/glib-The-Main-Event-Loop.html#GMainLoop"><span class="type">GMainLoop</span></a> in the default
 179 <a href="http://library.gnome.org/devel/glib/unstable/glib-The-Main-Event-Loop.html#GMainContext"><span class="type">GMainContext</span></a>, where one connects to the various signals, appends the
 180 URIs to be processed (through <a class="link" href="gst-plugins-base-libs-gstdiscoverer.html#gst-discoverer-discover-uri-async" title="gst_discoverer_discover_uri_async ()"><code class="function">gst_discoverer_discover_uri_async()</code></a>) and then
 181 asks for the discovery to begin (through <a class="link" href="gst-plugins-base-libs-gstdiscoverer.html#gst-discoverer-start" title="gst_discoverer_start ()"><code class="function">gst_discoverer_start()</code></a>).
 182 </p>
