Relationships between media components (media ports) are more like siblings rather than parent-child, hence one media port does not normally stop or destroy one another. Rather, normally it's the upper layer logic that determines when to stop. So the pattern that we use so far is for the object to emit the EOF signal to a callback (see WAV/memory player for example), which application can use to stop the media flow.
