struct GstStreamCollection

struct GstStreamCollection {
  GstObject object;
};

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.
