I am developing an iPad app where I am playing the videos stored within the app itself. I am representing the list of videos in a table view. When I select a row, the video
corresponding to that row plays. But while performing this, sometimes screen goes black , no video is visible but only audio is playing.
I am aware that making the video play in fullscreen mode or using the MPMoviePlayerViewController eliminates this problem. But my requirement is that I don't want to play the movie in fullscreen initially. Please guide me on how this can be achieved.
-(void)playMovie {
MPMoviePlayerController *movieController = [[MPMoviePlayerController alloc] initWithContentURL:movieUrl];
self.moviePalyer = movieController;
[movieController release];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePalyerDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object: self.moviePalyer];
self.moviePalyer.view.frame = CGRectMake(240, 0, 561, 313);
self.moviePalyer.view.backgroundColor = [UIColor clearColor];
[self.moviePalyer prepareToPlay];
[self.view addSubview: self.moviePalyer.view];
[self.moviePalyer play];
}
-(void)moviePalyerDidFinish:(NSNotification*)notification
{
[moviePalyer.view removeFromSuperview];
[moviePalyer stop];
moviePalyer.initialPlaybackTime = -1.0;
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePalyer];
[moviePalyer release];
moviePalyer = nil;
}
NOTE: This is on ipad simulator
I have solved the issue. Previously I was creating the MPMoviePlayerController for each of the row selection, and releasing it in the moviedidfinish notification method .But now, instead of creating movieplayercontroller for every row selection, I am reusing the MPMoviePlayerControler object which has been already created.
Following is the Code snippet:
-(void)playMovie
{
if(self.moviePalyer == nil)
{
MPMoviePlayerController *movieController = [[MPMoviePlayerController alloc] initWithContentURL:url];
self.moviePalyer = movieController;
[movieController release];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePalyerDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePalyer];
self.moviePalyer.repeatMode = MPMovieRepeatModeOne;
self.moviePalyer.view.frame = CGRectMake(240, 0, 561, 313);
self.moviePalyer.view.backgroundColor = [UIColor clearColor];
}
else
{
[self.moviePalyer setContentURL:url];
[self stopMovie];
}
[self.view addSubview: self.moviePalyer.view];
[self.moviePalyer play];
}
-(void)stopMovie
{
[self.moviePalyer.view removeFromSuperview];
[self.moviePalyer stop];
self.moviePalyer.initialPlaybackTime = -1.0;
}
I am releasing the moviePlayer object in the dealloc method.
Hope this helps who is having the same issue.

I have a problem while playing a video in full screen mode using MPMoviePlayerViewController (works perfectly in normal mode).
CODE:
if (PlayV) {
self.previewView.hidden=NO;
self.videoController =[[MPMoviePlayerController alloc] initWithContentURL:self.videoURL];
[self.videoController.view setFrame:self.previewView .frame];
self.videoController.view.center=self.playBtn.center;
[self.previewView addSubview:self.videoController.view];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.videoController];
self.videoController.scalingMode = MPMovieScalingModeAspectFit;
self.videoController.controlStyle = MPMovieControlStyleNone;
[self.videoController play];
}
I got the solution. Add this line of code in playBtnAction method:
- (IBAction)playBtnAction:(id)sender {
[self.videoController setFullscreen:YES animated:YES];
}
and then add this line of code in your videoPlayBackDidFinish.
MPMoviePlayerController *player=[notification object];
if ([player respondsToSelector:#selector(setFullscreen:animated:)]) {
[player.view removeFromSuperview];
}
This code will check if the video is in fullscreen mode and bring it back to normal mode.
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:imagepath]]; //moviePlayer declared in .h and set URL
moviePlayer.view.frame = CGRectMake(364, 89, 660, 668); //set custom frame
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view]; //add to view
[moviePlayer setFullscreen:NO animated:YES];
This may help you.
i am just playing a video by using MPMoviePlayerController...my code is
-(void)playMovie:(NSURL *)url
{
moviePlayer =
[[MPMoviePlayerController alloc]
initWithContentURL:url];
if (IDIOM==IPAD) {
[moviePlayer.view setFrame:CGRectMake(22,100, 720, 300)];
}
else
{
(IS_IPHONE_5)? [moviePlayer.view setFrame:CGRectMake(22, 70, 280, 150)]:[moviePlayer.view setFrame:CGRectMake(22, 40, 260, 140)];
}
[_scrollView addSubview:moviePlayer.view];
moviePlayer.scalingMode =MPMovieScalingModeFill;
[moviePlayer prepareToPlay];
[moviePlayer play];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerDidEnterFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:Nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerDidExitFullScreen:) name:MPMoviePlayerDidExitFullscreenNotification object:Nil];
}
-(void)moviePlayerDidEnterFullscreen :(id)sender
{
NSLog(#"fullscreen");
[moviePlayer play];
moviePlayer.scalingMode =MPMovieScalingModeFill;
}
- (void) moviePlayerDidExitFullScreen:(id)sender {
NSLog(#"exit full screen");
[moviePlayer play];
moviePlayer.scalingMode =MPMovieScalingModeFill;
}
here when i play initially video will be in "MPMovieScalingModeFill" mode...but my problem is that if i press full screen it shows video on full screen ..when i press exit "full screen" then my video mode goes to "MPMovieScalingModeAspectFit" mode.but i need to be always in "MPMovieScalingModeFill" mode .whats wrong with my code..Please help me...
I believe this will generate the MPMoviePlayerScalingModeDidChangeNotification.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieScalingModeDidChange:)
name:MPMoviePlayerScalingModeDidChangeNotification
object:nil];
Source :Apple Doc
MPMoviePlayerScalingModeDidChangeNotification
Posted when the scaling mode of a movie player has changed. There is no userInfo dictionary.
Scaling mode can change programmatically or by user interaction. To set or retrieve the scaling mode of a movie player, access its scalingMode property. The movie player whose state has changed is available as the object associated with the notification.
First set the ScalingMode to None and then set the ScalingMode to AspectFill
Swift Code :
NSNotificationCenter.defaultCenter().addObserver(self, selector: "moviePlayerExitFullscreen:", name: MPMoviePlayerDidExitFullscreenNotification, object: self.moviePlayer)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "moviePlayerEnterFullscreen:", name: MPMoviePlayerWillEnterFullscreenNotification, object: self.moviePlayer)
func moviePlayerEnterFullscreen (notification : NSNotification)
{
self.moviePlayer.scalingMode = MPMovieScalingMode.None
self.moviePlayer.scalingMode = MPMovieScalingMode.AspectFill
}
func moviePlayerExitFullscreen (notification : NSNotification)
{
self.moviePlayer.scalingMode = MPMovieScalingMode.None
self.moviePlayer.scalingMode = MPMovieScalingMode.AspectFill
}
This isn't the "ideal" solution, but it works! Basically, once you exit full screen the MPMoviePlayerController instance gets all screwed up and resetting the scaling property to MPMovieScalingModeFill won't help no matter where or when you do it (I've tried all sorts of stuff and after an hour gave up). Easiest solution is to remove the MPMoviePlayerController and simply allocate a new instance of MPMoviePlayerController each time full screen is exited (not ideal, but totally works):
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:NO];
if (self.moviePlayer != nil)
[self.moviePlayer.view removeFromSuperview];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:self.videoURL];
self.moviePlayer.view.frame = CGRectMake(#, #, #, #);
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayer.shouldAutoplay = NO;
[self.moviePlayer setContentURL:self.videoURL];
[self.moviePlayer prepareToPlay];
[self.moviePlayer setScalingMode:MPMovieScalingModeFill];
[self.view addSubview:self.moviePlayer.view];
}
PS: Don't forget to call super on viewDidAppear or suffer all sorts of unforeseeable mayhem (a very common mistake in iOS development)
I'm working on a project in which, video will be played when a button is clicked. MPMoviePlayer worked fine before I use this button action. But after implementing that, Video plays fine but the player doesn't recognise touch and it doesn't even shows playback time. Only showing like this ( - - ).
I'm working on this code:
-(void) sceneBegins:(id)sender
{
....
theMoviePlayer = [MPMoviePlayerController new];
[theMoviePlayer setContentURL:movieURL];
theMoviePlayer.controlStyle = MPMovieControlStyleEmbedded;
theMoviePlayer.backgroundView.hidden = YES;
[theMoviePlayer setMovieSourceType:MPMovieSourceTypeFile];
theMoviePlayer.shouldAutoplay = YES;
[theMoviePlayer prepareToPlay];
[theMoviePlayer.view setFrame:View.bounds];
[theMoviePlayer.view setUserInteractionEnabled:YES];
theMoviePlayer.scalingMode = MPMovieScalingModeAspectFit;
[View addSubview:theMoviePlayer.view];
theMoviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
[theMoviePlayer play];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(sceneChange:)
name:MPMoviePlayerPlaybackDidFinishNotification object:theMoviePlayer];
....
}
Also it doesn't enters in to the stop notification method when the video stops playing.
Try this line of code :-
[myButton addTarget:self action:#selector(dragEnded:withEvent: )
forControlEvents: UIControlEventTouchUpInside |
UIControlEventTouchUpOutside];
I'm playing a video from an MPMoviePlayer (not fullscreen), when I enter fullscreen the video keeps playing and fullscreen is shown.
But when I close fullscreen again, I can only see the black background on the place the 'small' video was playing. It doesnt respond to touches or anything.
I never call stop on my player and there is no viewdiddissapear (or similar) function declared.
The movieplayer also isnt released.
I want the video to continue playing when i close fullscreen. Any thoughts?
**EDIT
It works on an iPad 1, but not on an iPad 2... strange... I need it to function on all though.
Movieplayer initialization:
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
self.moviePlayer = [[MPMoviePlayerController alloc] init];
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
self.moviePlayer.contentURL = fileURL;
self.moviePlayer.backgroundView.backgroundColor = [UIColor blackColor];
self.moviePlayer.shouldAutoplay = YES;
[self.moviePlayer.view setFrame:CGRectMake(1024, floorf((self.view.bounds.size.height / 2) - (318 / 2)), 425, 318)];
[self.moviePlayer prepareToPlay];
[[NSNotificationCenter defaultCenter] addObserver:self

[self.view bringSubviewToFront:self.moviePlayer.view];
[UIView animateWithDuration:0.25

self.moviePlayer.view.position.y);
}
completion:nil];

I am writing a simple method to start a streaming video full-screen and letting the user quit pressing the "Done" button. Problem is, I can't remove the MPMediaPlayerController view, or perhaps I am doing it the wrong way.
- (IBAction)playVideoButtonPressed:(id)sender {
NSURL *url = [NSURL URLWithString:#"http://mysite.com/video.mov"];
mp = [[MPMoviePlayerController alloc] initWithContentURL: url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayerPlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
if ([mp respondsToSelector:#selector(setFullscreen:animated:)]) {
mp.controlStyle = MPMovieControlStyleFullscreen;
mp.shouldAutoplay = YES;
[self.view addSubview:mp.view];
[mp.view setTag:3];
[mp setFullscreen:YES animated:YES];
}
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mp];
[mp play];
}
- (void)moviePlayBackDidFinish:(id)sender {
NSLog(#"Quitting MoviePlayer");
[mp.view removeFromSuperview];
}
The idea is that the MPMediaPlayerController view is called clicking on a button in the app, and it is dismissed by clicking the "Done" video or when the video ends.
I should have used MPMoviePlayerViewController.
