| <p> |
| 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 |
| information as possible from one or many URIs. |
| </p> |
| <p> |
| It provides two APIs, allowing usage in blocking or non-blocking mode. |
| </p> |
| <p> |
| 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> |
| with the URI one wishes to discover. |
| </p> |
| <p> |
| 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 |
| <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 |
| 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 |
| 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>). |
| </p> |
| <p> |
| All the information is returned in a <a class="link" href="gst-plugins-base-libs-gstdiscoverer.html#GstDiscovererInfo"><span class="type">GstDiscovererInfo</span></a> structure. |
