* #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.
