StreamPropertyChangedEvent class

The Session object dispatches a streamPropertyChanged event in the following circumstances:

When a publisher starts or stops publishing audio or video. This change causes the hasAudio or hasVideo property of the Stream object to change. This change results from a call to the publishAudio() or publishVideo() methods of the Publish object.
When the settings of the quality property of a stream are determined. For more information, see Stream.quality.

The StreamPropertyChangedEvent object defines the properties of the event object that is dispatched.
