<doc xml:space="preserve">The #GstDiscoverer is a utility object which allows to get as much
information as possible from one or many URIs.
It provides two APIs, allowing usage in blocking or non-blocking mode.
The blocking mode just requires calling gst_discoverer_discover_uri()
with the URI one wishes to discover.
The non-blocking mode requires a running #GMainLoop iterating a
#GMainContext, where one connects to the various signals, appends the
URIs to be processed (through gst_discoverer_discover_uri_async()) and then
asks for the discovery to begin (through gst_discoverer_start()).
By default this will use the GLib default main context unless you have
set a custom context using g_main_context_push_thread_default().
All the information is returned in a #GstDiscovererInfo structure.</doc>

stream type, one can find more media-specific information in
#GstDiscovererAudioInfo, #GstDiscovererVideoInfo, and
#GstDiscovererContainerInfo.
The #GstDiscovererStreamInfo represents the topology of the stream. Siblings
can be iterated over with gst_discoverer_stream_info_get_next() and
gst_discoverer_stream_info_get_previous(). Children (sub-streams) of a
stream can be accessed using the #GstDiscovererContainerInfo API.
As a simple example, if you run #GstDiscoverer on an AVI file with one audio
and one video stream, you will get a #GstDiscovererContainerInfo
corresponding to the AVI container, which in turn will have a
#GstDiscovererAudioInfo sub-stream and a #GstDiscovererVideoInfo sub-stream
for the audio and video streams respectively.</doc>
