1024x768 on ipad using MPMoviePlayerController - objective-c

Question

after a long day researching into why 1024x768 video would not work on an iPad 3, and a lot of forum hunting. I could not find any reasonable solutions to this problem. Seems a lot of people where having the same situation with only a black screen being shown.
Solution was to render out the video required as 1024x 748. Reason being the status bar shown at the top of an iPad is 20px.
I hope this solves a lot of user problems they are having with this situation.
Onto my next question....
I currently have a video embedded into my view via the MPMoviePlayerController. This video is on a constant loop(An animated menu). I then have three invisible buttons layered on top of the video to which methods are called. I only have one working at present, the other two just show alerts.
The problem I am having at present is that, when the button is clicked, I want another video to play. This is working perfectly, BUT i would like the first video to FIRST play to the end the go onto the play the next video, reason being, I need it too be seamless and not be obvious its going from one video to another.
Any feedback on this would be great....

Answer 1

Have you tried registering for playback notifications, specifically the MPMoviePlayerPlaybackDidFinishNotification, catchy huh? If you register for the notification when the button is hit:
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(introMovieFinished:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.playerViewController];
Then in that function:
- (void)introMovieFinished:(NSNotification*)note {
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.playerViewController];
// Do stuff.
}
You de-register your interest in the notifications and then start playing the next movie. Because you only register an interest when the button is hit you shouldn't receive the function call until the movie finishes.
