get_stream_id

Returns the current stream-id for the this, or null if none has been set yet, i.e. the pad has not received a stream-start event yet.

This is a convenience wrapper around get_sticky_event and parse_stream_start.

The returned stream-id string should be treated as an opaque string, its contents should not be interpreted.

Parameters:

this	A source Pad

Returns:

a newly-allocated copy of the stream-id for this, or null. g_free the returned string when no longer needed.
