<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>

The #GstDiscovererStreamInfo represents the topology of the stream. Siblings
