audio-rate to video-rate and handles renegotiation (downstream video size
changes).
It also provides several background shading effects. These effects are

<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>
