Struct gstreamer_pbutils::DiscovererStreamInfo

pub struct DiscovererStreamInfo(_, _);

Base structure for information concerning a media stream. Depending on the stream type, one can find more media-specific information in DiscovererAudioInfo, DiscovererVideoInfo, and DiscovererContainerInfo.

The DiscovererStreamInfo represents the topology of the stream. Siblings can be iterated over with DiscovererStreamInfoExt::get_next and DiscovererStreamInfoExt::get_previous. Children (sub-streams) of a stream can be accessed using the DiscovererContainerInfo API.

As a simple example, if you run Discoverer on an AVI file with one audio and one video stream, you will get a DiscovererContainerInfo corresponding to the AVI container, which in turn will have a DiscovererAudioInfo sub-stream and a DiscovererVideoInfo sub-stream for the audio and video streams respectively.
