Struct gstreamer::Stream [−][src]
pub struct Stream(_);
A high-level object representing a single stream. It might be backed, or
not, by an actual flow of data in a pipeline (crate::Pad
).
A crate::Stream
does not care about data changes (such as decoding, encoding,
parsing,…) as long as the underlying data flow corresponds to the same
high-level flow (ex: a certain audio track).
A crate::Stream
contains all the information pertinent to a stream, such as
stream-id, tags, caps, type, …
Elements can subclass a crate::Stream
for internal usage (to contain information
pertinent to streams of data).
