can anybody tell me, when QTMovieTimeDidChangeNotification is fired? I
was hoping it will be posted, when the timecode of a movie is changed,
that is as a new frame is being displayed but that doesn't seem to be
the case.
As a rule of thumb: not when you would expect. For instance if you
have a movie, a selection, "plays selection only" and you play the
notification will be sent *before* any frame is displayed. If you ask
the movie for its current time upon receiving the notification you'll
see that it has not changed! Seems pretty useless as it is now, if
we're not mistaken.
Is there another way (*except using the callback mechanism in the
standard quicktime controller*) to be notified of a movie's progress?
Also, I'd prefer not to use an NSTimer as that will fire even when the
movie's not playing.
We ended up using a Timer. You can always start and stop your timer.
