The MediaPlayerItem.timedMetadata property provides access to all TimedMetadata objects that are created from playlist/manifest tags or from ID3 tags in the media stream.
MediaPlayerItem.hasTimedMetadata property indicates whether a subscribed custom tag exists in the current media. You can monitor timed metadata by listening for the
Events.TimedMetadataEvent, which the MediaPlayer instance dispatches each time a new
TimedMetadata object is created.
