/**
* GstStreamCollection:
*
* A collection of #GstStream that are available.
*
* A #GstStreamCollection will be provided by elements that can make those
* streams available. Applications can use the collection to show the user
* what streams are available by using %gst_stream_collection_get_stream()
*
* Once posted, a #GstStreamCollection is immutable. Updates are made by sending
* a new #GstStreamCollection message, which may or may not share some of
* the #GstStream objects from the collection it replaces. The receiver can check
* the sender of a stream collection message to know which collection is
* obsoleted.
*
* Several elements in a pipeline can provide #GstStreamCollection.
*
* Applications can activate streams from a collection by using the
* #GST_EVENT_SELECT_STREAMS event on a pipeline, bin or element.
*
* Since: 1.10
