Description​

Stage executor that fills in stream metadata defaults on passing samples.

Applies StreamMetadataDefaults to incoming samples (stream id, caps, label, port name, media type, format, payload tag, sequence numbers) and forwards them downstream. Used to attach a stable identity to a stream of samples that originate without one.
