Struct gstreamer_pbutils::DiscovererStreamInfo
source · pub struct DiscovererStreamInfo { /* private fields */ }
Expand 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 DiscovererStreamInfoExt::next()
and
DiscovererStreamInfoExt::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.
