GI.GstPbutils.Objects.DiscovererStreamInfo
Contents
Description
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 discovererStreamInfoGetNext and
discovererStreamInfoGetPrevious. 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.
