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.

I need to write an application where there are different short video loops in the background of a View. These loops should typically have a length of 10-30 seconds. I was wondering what would be better in terms of performance and memory economics (the loops should be bundled with the app when downloaded from the appstore)
a) Use a UIWebview as Background where an animated .gif of the video is looped
b) Use some VideoPlayerView (AVPlayer) as Background with an m4v-like file
c) Some alternative that I haven't considered yet
There will also be audio, however audio is not linked to the video

Try this, i hope it helps
For some reason, the cleanupPlayer method is a little buggy and isn't releasing the audio player correctly. My application crashes from time to time, and I suspect it's due to a memory issue. Also, when I try to play an audio file twice (on button click), the second time the audio sometimes cuts out. I'm a bit of a newbie, so any help would be greatly appreciated!
Here is a snippet of code:
.h file:
#property (retain,nonatomic)AVAudioPlayer *player;
.m file:
-(void)playSound:(NSString *)fileName
{
// Play
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:fileName ofType:kSoundFileType]];
_player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
_player.delegate = self;
[_player prepareToPlay];
[_player play];
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
[self cleanupPlayer];
}
-(void)cleanupPlayer
{
if(_player != nil) {
[_player release];
}
try this...
-(void)playSound:(NSString *)fileName
{
if (_player.isPlaying) {
[_player stop];
}
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:fileName ofType:#"mp3"]];
_player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
_player.delegate = self;
[_player prepareToPlay];
[_player play];
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
[self cleanupPlayer];
}
-(void)cleanupPlayer
{
_player =nil;
}
would you please help me with this code, I'm trying to play video but I'm having error Exc_bad_Access code = 1 and some times code = 2:

Waiting for your advice
It looks like your MPMoviePlayerViewController isn't retained, so it is probably getting deleted.
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];
// .....
}
