I'm trying to implement a notification in to my movie player, so that once the movie is done playing, it will exit fullscreen. The code is have so far i posted below. The IBAction is hooked up to a button. Also on a side note, i have been trying to figure out how to get the "play symbol" on top of my movie view, so that the user just have to press that and the video will start. Anybody know how to implement that?
- (void)viewDidLoad
{
//Video player
NSString *url = [[NSBundle mainBundle] pathForResource:self.navigationItem.title ofType:#"mov"];
_player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath: url]];
_player.view.frame = CGRectMake(350, 200, 400, 400);
[self.view addSubview:_player.view];
}
- (IBAction)playMovie
{
[_player play];
}
You can detect when your movie finishes playing by registering for an MPMoviePlayerPlaybackDidFinishNotification notification in your viewDidLoad method:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playerPlaybackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:_player];
And then perform whatever action you want to do in the callback method you specified when registering:
- (void) playerPlaybackDidFinish:(NSNotification*)notification
{
// movie finished playing
_player.fullscreen = NO;
}

My client asks me to read a short video as a splahscreen (as it is done especially for games for example). I googled for a bit and I think the guys use a MPMoviePlayerController with StyleControl to None (correct me if I'm wrong...)
I tried with a video from my iPhone (normally in the right format so ....), but remains black. My background is red, I see it appear at the beginning, then it is hidden by my video, which remains black and never starts.
However, I set out the frame of my video (self.view is initialized at the time), I add the player to view my self.view ... In short, I do not see what might messing around.
This is the code (with FullScreen controls to try to see, but I never see them either.
An idea by any chance?
Thx guys ;)

you may try:

i made a video playing when my app loads however it doen't quit after playing even if you prees "Done". What am i doing wrong?
- (void)viewDidLoad {
NSBundle *bundle=[NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"Video Logo Final" ofType:#"mp4"];
NSURL *movieURL=[[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.scalingMode = MPMovieScalingModeAspectFill;
theMovie.view.frame = CGRectMake(0.0, 0.0, 320.0, 480.0);
[self.view addSubview:theMovie.view];
[theMovie play];
[super viewDidLoad]; }
Also, i made a try to put the same code in "application didFinishLaunchingWithOptions" but i get a warning at "[self.view addSubview:theMovie.view];"
Ay ideas about that?
p.s. As you probably guessed i am very new to programming, any help would be really appreciated...
Basically you need to register for a notification.
The way I do it is:
// Register for the playback finished notification
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(myMovieFinishedCallback:)
name: MPMoviePlayerPlaybackDidFinishNotification
object: theMovie];
Change the parameters to fit however it should in your app.
Here's the documentation for the MPMoviePlayerPlaybackDidFinishNotification.
Also, if it's not "quitting" after playing (even when hitting the "Done" button), it sounds like you need to remove the theMovie MPMoviePlayerController and associated view from the view you originally added it to.
I have encountered a problem with the MPMoviePlayerController in 3.1.2.
If I cancel the player while it is still loading, the player closes. However, the video starts playing a few moments later in the background. The only ways to stop it are to play another video or close the app. This seems to work fine in 3.2+.
Here's what I'm doing:
- (void)loadMoviePlayer
{
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
if ([NSClassFromString(#"MPMoviePlayerController") instancesRespondToSelector:#selector(view)])
{
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
// running iOS 3.2 or better
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:#"http://www.mysite.com/myvideo.m3u8"]];
[moviePlayer.view setBackgroundColor:[UIColor blackColor]];
[moviePlayer.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
// [moviePlayer.moviePlayer setControlStyle:MPMovieControlStyleNone];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
[moviePlayer.moviePlayer prepareToPlay];
[moviePlayer.moviePlayer play];
#endif
}
else
{
MPMoviePlayerController *mMPPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:#"http://www.mysite.com/myvideo.m3u8"]];
mMPPlayer.scalingMode=MPMovieScalingModeFill;
mMPPlayer.backgroundColor=[UIColor blackColor];
[mMPPlayer play];
}
}
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
// Remove observer
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[self dismissModalViewControllerAnimated:YES];
}
I added moviePlayBackDidFinish this morning. It gets called when I hit cancel, but dismissModalViewControllerAnimated doesn't seem to do anything. I also tried removeFromSuperView, but my player will not respond.
So, how can I make sure the player does not play after hitting "cancel"?
Thanks in advance.
You may have come across an old bug in MPMoviePlayerController. Back in the days, we actually had to play an almost empty (black, silence) M4V after playing proper content to be sure the player does not attempt to continue playback in the background when stopping at certain stages. That bug manifests in audible sound but no picture of the aborted/stopped video.
There are however a few more things worth trying when stopping (assuming your instance of MPMoviePlayerController is called moviePlayer);
set the current playback position to the complete movie duration moviePlayer.currentPlaybackTime = moviePlayer.duration;
send another stop within your notification handler [moviePlayer stop];
In my case, I found that setting the following line would eventually stop the movie player from playing:
moviePlayer.contentURL = nil;
(with moviePlayer your instance of MPMoviePlayerController).
I have a class that plays a repeating background music loop with an AVAudioPlayer, and on specific occasion, plays a full-screen video with its own sound track using MPMoviePlayerController. In order to to have only one track at a time, I stop the background music before launching the video:
-(void)startVideo{
[backgroundMusic stop];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"videofile" ofType:#"m4v"]]];
[self presentMoviePlayerViewControllerAnimated:mp];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoOver) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[mp.moviePlayer play];
[mp release];
}
-(void)videoOver{
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
if(![backgroundMusic play]){
NSLog(#"bad: can't resume bg music!");
[backgroundMusic release];
backgroundMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"videofile" ofType:#"m4v"]] error:NULL];
backgroundMusic.delegate = self;
backgroundMusic.numberOfLoops = -1;
[backgroundMusic play];
}
}
The resumption worked fine without recreating the AVAudioPlayer object (i.e. the play method returned YES) on analogous code on os versions up to and including 3.2. But on iOS4, the play method always returns NO, and has to recreate the object. Why is that, and can I get to resume the background track properly (I have cases where the solution used above is unacceptable.)?
Figured this out. It turns out that in iOS 3.2 and above, when a video finishes playing, it goes into MPMoviePlaybackStatePaused state rather than MPMoviePlaybackStateStopped, and in order to make it release the hardware, you have to explicitly call the stop method on MPMoviePlayerController after it finishes playing before trying to resume AVAudioPlayer.
Iam trying to play a video from a remote location and trying to overlay a window over the entire screen which is more or less transparent with few images along the edges . As soon as the movie is preloaded I play the video. This happens good the first time. But if I try to replay the video it does not play the video and neither am i able to click on the Play button from the controls of the player. I guess the overlay window is over the controls. How do i get the controls over the overlay window.
//- (void)moviePlayerContentPreloadDidFinish:(NSNotification *)notification{
NSLog(#"content preloaded");
NSDictionary *userInfo = [notification userInfo];
if ([userInfo valueForKey:#"error"]) {
NSLog(#"*** An error occurred preloading the movie");
return;
}
[self.spinner stopAnimating];
// Add the overlay view to the movie, so we can catch the clicks
OverlayViewController *ovc = [[OverlayViewController alloc] initWithNibName:#"OverlayView" bundle:nil];
self.overlayController = ovc;
[ovc release];
[self.overlayController setNextResponder:self];
MPMoviePlayerController *moviePlayer = [notification object];
[moviePlayer play];
// Locate the movie player window
NSArray *windows = [[UIApplication sharedApplication] windows];
NSLog(#"window count= %d",[windows count]);
if ([windows count] < 2) {
NSLog(#"*** Window for movie player is missing");
return;
}
UIWindow *moviePlayerWindow = [windows objectAtIndex:1];
[moviePlayerWindow addSubview:self.overlayController.view];
}
The code that I use is
Am I doing something wrong. Is it possible to get the controls over the overlay or auto play it.
Two things.
First, according to your code, in the moviePlayBackDidFinish method you must first release the moviePlayer and then instantiate it again with an alloc. You must do that every time you want to play a video.
MPMoviePlayerController *moviePlayer = [notification object];
[moviePlayer release]
...
MPMoviePlayerController *newMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: anURL];
The structure of your code works, but I think you should better have a look at the example provided by apple:
http://developer.apple.com/iphone/library/samplecode/MoviePlayer_iPhone/index.html
Second, about the overlay, you are right, the overlay gets the events but you cannot put it under the movie player controls. What you have to do is to use the events you receive in your overlay to control the player. You could use touchesBegan event to pass the initial touch event and use it with the player (play, pause, stop).
