gst.stream_collection

Module for [StreamCollection] class

class StreamCollection StreamCollectionGidBuilder StreamCollectionGidBuilderImpl

Types 3

classStreamCollection : gst.object.ObjectWrap

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.StreamCollection.getStream]

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.
