/**
 * A high-level object representing a single stream. It might be backed, or
 * not, by an actual flow of data in a pipeline (#GstPad).
 * 
 * A #GstStream 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 #GstStream contains all the information pertinent to a stream, such as
 * stream-id, tags, caps, type, ...
 * 
 * Elements can subclass a #GstStream for internal usage (to contain information
 * pertinent to streams of data).
