TimelineMetadata uses the TimelineMarker class to represent both keys and values (i.e. a TimelineMarker will be stored as both key and value). A TimelineMetadata object dispatches a TimelineMetadataEvent when the currentTime property of the MediaElement's TimeTrait matches any of the time values in its collection of TimelineMarker objects.

|
Emite
ArgumentError — If marker is null or specifies an invalid time.
|
getMarkerAt | () | método |
public function getMarkerAt(index:int):org.osmf.metadata:TimelineMarkerReturns the TimelineMarker at the specified index. Note that the markers are sorted by time.
Parámetros
index:int — The index of the marker to return.
