Question

I want to know how far the video had progressed when the user closes the video.

So for I have this:

- (void) moviePlayerDidFinsh:(NSNotification*) notification
{
    MPMoviePlayerController* moviePlayer = notification.object;
    NSLog(@"FINISHED duration was:%f", moviePlayer.duration);
}

initialPlaybackTime and endPlaybackTime both seam to be useless.

Answer 1

There is a property currentPlaybackTime in MPMediaPlayback protocol.

The current position of the playhead. (required)

@property(nonatomic) NSTimeInterval currentPlaybackTime

% value = currentPlaybackTime/duration;
