PointerInterface

public class StreamCollection
extends PropertyHolder

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.

StreamCollection

public StreamCollection(@Nullable
 Str upstream_id)

Create a new #GstStreamCollection.

Parameter:

upstream_id - The stream id of the parent stream

StreamCollection

public StreamCollection(String upstream_id)

Create a new #GstStreamCollection.

Parameter:

upstream_id - The stream id of the parent stream

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

addStream

public boolean addStream(@Nonnull
 Stream stream)

Add the given @stream to the @collection.

Parameter:

stream - the #GstStream to add

Gibt zurück:

%TRUE if the @stream was properly added, else %FALSE

getSize

public int getSize()

Get the number of streams this collection contains

Gibt zurück:

The number of streams that @collection contains

getStream

public Stream getStream(int index)

Retrieve the #GstStream with index @index from the collection.

The caller should not modify the returned #GstStream

Parameter:

index - Index of the stream to retrieve

Gibt zurück:

A #GstStream

getUpstreamId

public Str getUpstreamId()

Returns the upstream id of the @collection.

Gibt zurück:
