I have a problem with MPMoviePlayerController, i.e. I am playing the live stream url in (m3u8 format) MPMoviePlayer like below:
player = [[MPMoviePlayerController alloc] initWithContentURL:audioUrl];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(loadStateDidChange:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:player];
if ([player respondsToSelector:#selector(loadState)])
{
// Set movie player layout
[player setMovieSourceType:MPMovieSourceTypeStreaming];
[player setControlStyle:MPMovieControlModeVolumeOnly];
[player setFullscreen:YES];
[player prepareToPlay];
[player play];
}
}
It is working in both simulators & iPad device with ios 5 version, but it is not giving the audio in any iPhone device i have.
Please help me out...
Thanks, in advance.
mr simham ... check this below url it help for us becoZ
Call stream-url within mobile safari. If that has the same results, then your code is correct and the stream is not. It would be an incorrectly encoded audio stream then.
it depends on bandwidth also below ref url regards to bandwidth check it once.... u r ref Stream URL prepare,according to BandWith

You are assigning a deprecated MPMovieControlMode (MPMovieControlModeVolumeOnly) towards the controlStyle property which is expecting a MPMovieControlStyle.
Additionally, your code is missing the part that assigns the MPMoviePlayerController.view towards any superview and also its sizing is missing.
Last but I guess most importantly for you, I am guessing that the iPhone you are trying it with has set the volume all the way down to silence. Or, maybe the audio-routing is not set towards speaker-output. For the latter, make sure you are not setting up the audio session incorrectly anywhere else in your App. When in doubt, try fiddling with the useApplicationAudioSession property. Try setting it towards NO and see if that changes your results.
If all above fails, then one additional check would be to call the stream-url within mobile safari. If that has the same results, then your code is correct and the stream is not. It would be an incorrectly encoded audio stream then.
Check if your iPhone is on loudspeaker mode or not -
if not than set it using this-
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
Check if the iPhone is in silent mode. To play audio even in silent mode, add the following code in AppDelegate's application:didFinishLaunchingWithOptions:
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];

I am using the following code to play a audio in iOS using **AVAudioPlayer** class.
NSString *audioPath = [[NSBundle mainBundle] pathForResource:#"myAudio" ofType:#"mp3"];
NSURL *audioURL = [[NSURL alloc] initFileURLWithPath:audioPath];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error];
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
[audioPlayer play];
This is working fine in simulator. But, i am not getting the sound output when i run it on the device. The delegate methods ofAVAudioPlayerDelegate are also being called but there is no volume output. Where am i going wrong here.... Another important aspect i'v noticed here is that, i am getting a large message in my GDB while playing the audio file on simulator. But the same thing is not happening on device... Please refer the screenshot below for GDB messages while running on the simulator.
Check if your device is on loudspeaker mode or not..
to listen the sound through Loundspeaker use this -
// set audio to loudSpeaker mode for iphone
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
or you can increase the volume of your audio file using this -
Player.volume = 10.0;
Have you tried the .caf or .wav file? might possible that .mp3 is not working on iPhone. Also check the duration of your file not greater than 30 sec.
I was so so stupid.... My volume button was turned off. That was the reason.
Really sorry for wasting your time guys... My sincere apologies.
I'm using AVAudioPlayer to play music (background supported). My question is if I want to call somebody while I'm listening to the music, how to resume it after the call? I've implement the AVAudioPlayer's delegate method:
- (void)audioPlayerEndInterruption:(AVAudioPlayer *)thePlayer {
[[AVAudioSession sharedInstance] setActive:YES error:nil];
[self.player play];
}
but this will not allow the music to continue.
I've also tried to use the AVAudioSessionDelegate method (just a try):
- (void)viewDidLoad {
[[AVAudioSession sharedInstance] setDelegate:self];
}
- (void)endInterruption
{
[[AVAudioSession sharedInstance] setActive:YES error:nil];
[self.player play];
}
but again this won't cause the music to resume. Any ideas about how to solve this problem?
strange from your code is, you're telling that you do use AVAudioPlayer, why do you then implement AVAudioSessionDelegate?
And you have bad implementation of delegate methods. See docs
from AVAudioPlayerDelegate:
- (void)audioPlayerEndInterruption:(AVAudioPlayer *)player
- (void)audioPlayerEndInterruption:(AVAudioPlayer *)player withFlags:(NSUInteger)flags
So try to implement them like this, and it should be working properly
On iOS, an app can not start playing audio when already in the background. If your app's audio is stopped because a foreground app has taken control of the audio session, there is (currently) no way to take it back.
You can resume it. After finishing your audio session you have to notify other app that my app deactivate the audio session and you can make use of it. Use the following code.
[[AVAudioSession sharedInstance] setActive:NO withFlags:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:&error];
I'm having trouble getting MPMoviePlayerController to work on the device. It runs fine in simulator, playing a five-second video and then sending the appropriate callback (myMovieFinishedCallback:) to the view controller. When it runs on the device, the movie never shows up, even though I can trace through [player play] with no problems. myMovieFinishedCallback: is never called, and there are no errors. All the right resources are being copied. Any idea what's going on?
Here's the code I use to create and use the player,
Update: I've switched over to using MPMoviePlayerViewController. On the device the movie still does not play, I just get the spinning progress wheel indefinitely. The controls also flash briefly even though I've set the player to MPMovieControlStyleNone - anybody know how I can fix this? The movie is five seconds and about 1.5 MB if that makes any difference.
Update: Other movie files work, but I can't figure out how to make mine work. I've tried it as a .mov and a .mp4 and the settings seem to be right. Any idea what would cause the MPMoviePlayer to show a progress wheel forever on the device only?
- (void) playMovie
{
NSString *url = [[NSBundle mainBundle]
pathForResource:#"myMovie"
ofType:#"mp4"];
MPMoviePlayerViewController *playerViewController =
[[MPMoviePlayerViewController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];
playerViewController.moviePlayer.controlStyle = MPMovieControlStyleNone;
playerViewController.moviePlayer.scalingMode = MPMovieScalingModeFill;
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:[playerViewController moviePlayer]];
playerViewController.view.frame = movieView.frame;
[movieView addSubview:playerViewController.view];
//---play movie---
MPMoviePlayerController *player = [playerViewController moviePlayer];
[player play];
}
Your code works fine for me, so there are two possibilities that come to mind (there may be others):
You movieView has not been properly initialized or has not had its frame set so that it's visible.
The video format of the video you're displaying isn't supported on the device.
I would try using a different video. Maybe one you can confirm you've played on the device before. Here's the little demo project I threw together: http://www.cimgf.com/files/PlayMovie.zip
I ran audio in the background in my iPhone app using AVAudioPlayer and AVAudioSession...
Now my problem is that I already have a written code that takes a number of songs as input from the user and plays them one after the other using AVAudioPlayer...
The problem is that when the app goes to the background while one of the files is being played, the audio continues but when it's done, the sound disappears... In foreground when a file is done, I just do some code to play the next one but in the background this is not possible...
I thought about requesting some time to get this done and run my code but I can't do this as the audio files always change and they might be long... So please tell me what should I do? Is there any built-in playlist player that run as a background audio? or is there any other solution? I really need to get this into work...
thanks a lot
I ran into the same issue and haven't completely resolved it yet. The audioDidFinishPlaying delegate method still fires, and you can use UIAplication's beginBackgroundTask to create a new instance of AVaudioPlayer, make sure AVAudioSession is still active, etc. But when I try to play the new AVAudioPlayer instance, it pauses immediately. My suspicion/fear is that there is no way to start the audio FROM the background, only keep it playing when the application state transition happens. I'd love to be wrong, though.
this is easy ..just change the cateogry if your using an audio session that is ...
http://developer.apple.com/library/ios/#documentation/Audio/Conceptual/AudioSessionProgrammingGuide/AudioSessionCategories/AudioSessionCategories.html
the link has the categories ...so use one of these and you be able to start the sound in the background:
AVAudioSessionCategoryPlayback
kAudioSessionCategory_MediaPlayback
the ambient one might not work.
//ViewController.h ,write below code
#interface ViewController : UIViewController<AVAudioRecorderDelegate,AVAudioPlayerDelegate>
//assign property to player
#property(nonatomic,retain) AVAudioPlayer *player;
//then write in ViewController.m file in ViewDidLoad Method below code
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
NSError *soundError;
NSString *path=[[NSBundle mainBundle]pathForResource:#"soundFileName" ofType:#"mp3"]; //.mp3 file for player
NSURL *file=[[NSURL alloc]initFileURLWithPath:path]; //path
_player=[[AVAudioPlayer alloc]initWithContentsOfURL:file error:&soundError]; //player Object
if(_player == nil)
{
NSLog(#"player is empty because of %#",soundError);
}
else
{
[_player play];
_player.volume=1.0;
[_player setDelegate:self];
}
// for stop player you can use
// [_player stop]; //uncomment this line when you wants to stop it.
I've got an iPhone app with a short intro video. If a user launches the app while their iPod is playing music, the music will stop while the video plays (whether or not the video has sound), and the audio stays permanently stopped after video playback.
Apple seems to indicate that you can solve this with AudioSession tricks:
https://web.archive.org/web/20100819124854/http://developer.apple.com:80/iPhone/library/documentation/Audio/Conceptual/AudioSessionProgrammingGuide/WorkingWithOpenALiPodMusicandMovies/WorkingWithOpenALiPodMusicandMovies.html
But their suggestions here just don't seem to work; it seems like MPMoviePlayerController overrides the audio session configuration for its own purposes. Ideally I'd mix the movie audio over the iPod audio or maybe use ducking, but even restarting the music might be a passable fix.
I've found a great solution for that. In the .h file, you must create a BOOL called "wasPlaying". Before playing your video, you ask the iPod if it was playing.
if ([[MPMusicPlayerController iPodMusicPlayer] playbackState] == MPMusicPlaybackStatePlaying)
{
NSLog(#"Music was playing, lets put YES to the bool");
wasPlaying = YES;
}
Then, after you tell the movie player to play, you call the following:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(finishedPlaying) name:MPMoviePlayerPlaybackDidFinishNotification object: moviePlayer];
And after that, in the method finishedPlaying:
if (wasPlaying ==YES)
{
NSLog(#"Music was playing, lets play music again");
[[MPMusicPlayerController iPodMusicPlayer] play];
}
For me it worked fine!
I think you can do this by initializing the audio session similar to this:
NSError *audioSessionError = nil;
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryAmbient
error:&audioSessionError] == YES)
Then when you want to use the audio session you can set the iPod audio to duck the video track:
AudioSessionInitialize (NULL, NULL, NULL, NULL);
OSStatus propertySetError = 0;
UInt32 allowMixing = true;
propertySetError |= AudioSessionSetProperty(kAudioSessionProperty_OtherMixableAudioShouldDuck, sizeof(allowMixing), &allowMixing);
AudioSessionSetActive(YES);
You can only have a single music-providing app at any time and multiple sources of (brief) sounds. If a background app is playing music, your app can overlay brief sounds. If you want to play music, the background app has to be stopped.
So I don't think that what you're trying to achieve is possible using MPMoviePlayerController (or any of the high-level audio frameworks). You might be able to overlay an audio track of a movie, if it's sufficiently short but MPMoviePlayerController is probably not good for this.
