Waiting for your advice

It looks like your MPMoviePlayerViewController isn't retained, so it is probably getting deleted.

Replacing AVPlayer with MPMoviePlayerController

I am trying to replace AVPlayer with MPMoviePlayerController as I want to be able to add an animation with transparent background to a view. The problem is the animation is not displaying with MPMoviePlayerController.
Please find my lines below. The first portion is with AVPlayer and it's work. The second is with MPMoviePlayerController and doesn't.
What the code does is it plays an animation and when this is done it is launching an action.
Code with AVPlayer (that works):
NSString *filepath = [[NSBundle mainBundle] pathForResource:theAnimationFileName ofType:theString;
//NSURL *fileURL = [NSURL fileURLWithPath:filepath];
// First create an AVPlayerItem
AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:fileURL];
// Subscribe to the AVPlayerItem's DidPlayToEndTime notification.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(itemDidFinishPlaying) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];
// Pass the AVPlayerItem to a new player
controlledPlayer = [[AVPlayer alloc] initWithPlayerItem:playerItem];
AVPlayerLayer *animatedLayer = [AVPlayerLayer playerLayerWithPlayer:controlledPlayer];
[animatedLayer setFrame:CGRectMake(0, 0, 1024, 1024)];
[thisReplacementView.layer addSublayer: animatedLayer];
// Begin playback
[controlledPlayer play];
Code with MPMoviePlayerController (does not display anything):
NSString *moviePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:theString];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:moviePath]];
moviePlayer.controlStyle = MPMovieControlModeDefault;
moviePlayer.view.frame = CGRectMake(0, 0, 1024, 1024);
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(itemDidFinishPlaying) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
[thisReplacementView addSubview:moviePlayer.view];
[moviePlayer play];
NSURL *url = [NSURL URLWithString:#"http://iOS.mp4"];
self.moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
NSError *_error = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: &_error];
[self presentMoviePlayerViewControllerAnimated:self.moviePlayer];
-(void)playbackFinishedCallback:(NSNotification *)notification{
self.moviePlayer = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
{
self.moviePlayer = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer];
[self.moviePlayer.view removeFromSuperview];
}

MPMediaPlayer always crashes

I try to add a video to Viewcontroller but always fails : some one can help?
-(id) init
{
// always call "super" init // Apple recommends to re-assign "self" with the "super's" return value
if(self=[super init])
{
//play // [[[CCDirector sharedDirector] view] addSubview:viewController.view];
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"Movie" ofType:#"m4v"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[viewController.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
moviePlayerController.controlStyle = MPMovieControlStyleNone;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(movieDone:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController]; [moviePlayerController play];
//play
}
return self;
}
In ViewController.h
MPMoviePlayerController *moviePlayerController;
In ViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"try" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[moviePlayerController.view setFrame:CGRectMake(0, 10, 320,300)];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
moviePlayerController.controlStyle=MPMovieControlStyleEmbedded;
[moviePlayerController play];
}

Audio playback for movie despite in silent mode?

sorry for my question but i´ve implemented a intro- video and despite of the hardware silent-switch of my iPad, the audio is playing.
I´m also using the AVAudioplayer within my app just for playing short sound samples. Within this class, its the only region where i´ve set up the "AVAudioSessionCategory".
But for all audio playback only, there´s nothing hearable. Its just for my intro-video.
Any help how to fix that "audio-bug" so the movie player is silent?
Thanks you
Here´s my Audio-class:
- (id)initWithSoundfileName:(NSString*) file
{
if ((self = [super init]))
{
NSString* filename = [file stringByDeletingPathExtension];
NSString* fileextension = [file pathExtension];
// get file path from bundle
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: filename ofType: fileextension];
NSLog(#"AudioPlayer init: %#", soundFilePath);
NSURL* fileurl = [[NSURL alloc] initFileURLWithPath:soundFilePath];
NSError* error = nil;
AVAudioPlayer* audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileurl error:&error ];
if (error) { NSLog(#"Error creating AVAudioPlayer %#", [error description]);}
// set audio policy
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:NULL];
self.player = audioplayer;
[self.player prepareToPlay];
[self.player setDelegate:self];
}
return self;
}
-(void) play{
[self.player play];
}
And here´s my video-playback method:
- (void)playIntroVideo
{
NSString *movpath = [[NSBundle mainBundle] pathForResource:#"mymovie" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:movpath];
self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
self.moviePlayerController.fullscreen = YES;
self.moviePlayerController.scalingMode = MPMovieScalingModeAspectFit;
self.moviePlayerController.controlStyle = MPMovieControlStyleNone;
self.moviePlayerController.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayerController.useApplicationAudioSession = NO;
[self.moviePlayerController.view setFrame: self.view.bounds];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlaybackStateChanged:)
name:MPMoviePlayerPlaybackStateDidChangeNotification
object:self.moviePlayerController];
[self.view addSubview:self.moviePlayerController.view];
[self.moviePlayerController prepareToPlay];
[self.moviePlayerController play];
}
Like #Till mentioned:
When I change the MoviePlayerController property to useApplicationAudioSession=TRUE, it fixes my problem. Audio Playback is silent.

Movie play error

I am trying play a video on device. Video is this
video
and my code:
NSString *urlStr = #"http://easyhtml5video.com/images/happyfit2.mp4";
NSURL *url = [NSURL fileURLWithPath:urlStr];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[self.view addSubview:moviePlayer.view];
moviePlayer.view.frame = CGRectMake(0, 0, 320, 400);
[moviePlayer play];
When i start app an movie screen is seen but movie doesnt play. Can you help me where is the mistake ?
Try use
NSURL *url = [NSURL URLWithPath:urlStr];
instead of
NSURL *url = [NSURL fileURLWithPath:urlStr];
It is a web url not a file url.
Check this video for reference. This works for me -
- (IBAction)playMovie:(id)sender
{
NSString *filepath = #"http://easyhtml5video.com/images/happyfit2.mp4";
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[moviePlayerController.view removeFromSuperview];
[moviePlayerController release];
}

Video playback disappears after a few seconds

i want to play a video within a UIView using MPMoviePlayerController.
After pressing a UIButton, the video appears and starts playing.
Unfortunately after 3-4 seconds, the video gets black, the audio is still playing.
Any ideas?
Thanks for all your time.
(Using Xcode 4.2.1)
-(void) playMovieButtonPressed:(UIButton*) button{
NSString* video = #"testmovie.m4v";
NSString *filepath = [[NSBundle mainBundle] pathForResource:[video stringByDeletingPathExtension] ofType:[video pathExtension]];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController* player = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
player.movieSourceType = MPMovieSourceTypeFile;
[player.view setFrame:CGRectMake(20, 400, 300, 200)];
[self.view addSubview:player.view];
[player prepareToPlay];
[player play];
}
- (void) moviePlaybackComplete:(NSNotification*) notification {
NSLog(#"videoviewcontroller complete: %#", notification);
MPMoviePlayerController *mymoviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:mymoviePlayerController];
}
I´ve talked to an Apple Engineer. The solution is that the player would have to be an instance variable or property of the view controller. So its still accessible when view was being torn down.
-(void) playMovieButtonPressed:(UIButton*) button{
NSString* video = #"testmovie.m4v";
NSString *filepath = [[NSBundle mainBundle] pathForResource:[video stringByDeletingPathExtension] ofType:[video pathExtension]];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
// .....
}
