In that case `MediaStatus#playerState`\nis `IDLE`, but `ExtendedMediaStatus#playerState` is `LOADING`.\n\n### idleReason\n\n(non-null [cast.framework.messages.IdleReason](/cast/docs/reference/web_receiver/cast.framework.messages#.IdleReason) or undefined)\n\nIf the state is IDLE, the reason the player went to IDLE state.\n\n### items\n\n(non-null Array of non-null [cast.framework.messages.QueueItem](/cast/docs/reference/web_receiver/cast.framework.messages.QueueItem) or undefined)\n\nList of media queue items.\n\n### liveSeekableRange\n\n(non-null [cast.framework.messages.LiveSeekableRange](/cast/docs/reference/web_receiver/cast.framework.messages.LiveSeekableRange) or undefined)\n\nThe seekable range of a live or event stream.
