[−][src]Struct gstreamer::StreamCollection
A collection of Stream that are available.
A StreamCollection 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 StreamCollection::get_stream()
Once posted, a StreamCollection is immutable. Updates are made by sending
a new StreamCollection message, which may or may not share some of
the Stream 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 StreamCollection.
Applications can activate streams from a collection by using the
EventType::SelectStreams event on a pipeline, bin or element.

Implementations
impl StreamCollection[src]
pub fn get_size(&self) -> u32[src]
Get the number of streams this collection contains
Feature: v1_10
Returns
The number of streams that self contains
pub fn get_stream(&self, index: u32) -> Option<Stream>[src]
Retrieve the Stream with index index from the collection.
The caller should not modify the returned Stream
Feature: v1_10
index
Index of the stream to retrieve
Returns
A Stream
