Status messages can be sent by QuickTime’s streaming components or by any code that wants to display a message in the movie controller bar status area.
The userInfo dictionary contains a single entry whose value is of type NSString, which is the status message.
The following are keys (notification parameters) for userInfo items for the QTMovieStatusStringPostedNotification notification QTMovieStatusCodeNotificationParameter and QTMovieStatusStringNotificationParameter.
A status string notification can indicate an error (in which case QTMovieStatusCodeNotificationParameter will have a value), or it can contain a string (in which case QTMovieStatusStringNotificationParameter will have a value). For more information, see mcActionShowStatusString.
