# GstDiscoverer

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.

Base structure for information concerning a media stream. Depending on the 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.
