I'm attempting to use MPMusicPlayerController to play apple music songs, but I can't get the lock screen controls to work. It seems as though MPMusicPlayerController overridess the remoteControlReceivedWithEvent listener.
Here is how I set up my controller:
self.player = [MPMusicPlayerController applicationMusicPlayer];
self.player.repeatMode = MPMusicRepeatModeNone;
self.player.shuffleMode = MPMusicShuffleModeOff;
[self.player beginGeneratingPlaybackNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handlePlaybackStateChanged:) name:MPMusicPlayerControllerPlaybackStateDidChangeNotification object:self.player ];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handleItemChanged:) name:MPMusicPlayerControllerNowPlayingItemDidChangeNotification object:self.player ];
Then I play apple music songs:
NSMutableArray *storeIDS = [NSMutableArray arrayWithObjects:anthem.song.apple_id, #"1", nil];
[self.player setQueueWithStoreIDs:storeIDS];
[self.player play];
[self.player setCurrentPlaybackRate:1.0];
For reference, here is how I setup the remote control listener in didFinishLaunchingWithOptions:
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];
At this point, the player plays the song as requested, but I can no longer receive any remote control notifications. Hitting next/prev simply stop the song since it has reached the end of the list. I've tried with the applicationMusicPlayer as well as the systemMusicPlayer. I can't use AVPlayer or AVAudioPlayer because it's Apple Music and I cannot get the URL to stream.
Any ideas!?
To play from Apple Music use MPMusicPlayerController.systemMusicPlayer()

I do not have a problem a stream, but I do not know when it is buffering or when the stream has ended. Is there anyway to determine this in Objective-C. I have found solutions for audio and I even tried the AVPlayerItemDidPlayToEndTimeNotification but it does not work. Any suggestions?
NSString *url = liveStream.stream[#"cdn"];
dispatch_async(dispatch_get_main_queue(), ^{
AVPlayerItem *playerItem = [[AVPlayerItem alloc]
initWithURL:[NSURL URLWithString:url]];
[_player replaceCurrentItemWithPlayerItem:playerItem];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(itemDidFinishPlaying:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];
[_player play];
});
}
-(void)itemDidFinishPlaying:(NSNotification *) notification {
}
In addition to the notification you're using, you should use KVO to observe the rate of the avPlayer, as well as the status of the avplayer's current AVPlayer item. From observing those properties, you can make a state machine of sorts where your player view controller knows what's going on, and can recover from various changes instate. There are various player states that you have to prepare for and recover from based on the properties that you observe.
Here's an answer on how to check for buffering
Here's an example of a complete AVPLayer
And of course, here's apple's documentation on AVPlayer
Here's the documentation on AVPlayerItem
Lastly, here's the link on KVOController. You'll thank me for this later.
I want to play a video in seprate view controller, where I can Play/Pause or dismiss that view controller. In my case, I recorded the video in my app and calling this delegate method in order to save this video in assets, but I want to play it first before using the ALAssetsLibrary.
- (void)captureOutput:(AVCaptureFileOutput *)captureOutput
didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL
fromConnections:(NSArray *)connections
error:(NSError *)error
And the TEMO URL im getting is :
file:///private/var/mobile/Containers/Data/Application/EA6D31AC-6CC3-4BDF-B874-BC6F30BA5677/tmp/output.mov
How can I play this video in next view controller or in same view controller??
My try:
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:outputFileURL];
player.view.frame = CGRectMake(184, 200, 400, 300);
[self.view addSubview:player.view];
[player play];
PS: This is showing a black screen area but not actually playing this video.
I had the same problem a few days ago. It ends up that I was calling play method to soon, before the video become ready to play. So, add this before call [player play]. This will notify whenever your video become read to play in MPMoviePlayerController.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:player];
Then setup the observer:
- (void)videoPlayBackDidFinish:(NSNotification *)notification {
[[NSNotificationCenter defaultCenter]removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
}
This worked for me.
Hope it helps.
I am using the MPMoviePlayerController to play some streaming videos of type .m3u from a url. They video player launches perfectly and the video starts playing perfectly as well, but as soon as I press the Seek Forward or Next or beginSeekingForward button the video complete stops/freezes. After that I can click Done to dismiss the player or scrub the progress bar and it will come back to play to video. But the I can't click on the play/pause or at least seems not to do anything.
I have spent quite sometime looking around online for answer or at least a hint so I can tackle this issue in the right direction but not luck. So, I really hope someone could help with this. Btw, this only happens on iOS 8+, currently I am testing it in iOS 8.1.
This is how I create the player and load the video to it.
NSURL *videoURL = [NSURL URLWithString:self.video.flvurl];
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: videoURL];
self.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
self.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
self.moviePlayer.shouldAutoplay = NO;
self.moviePlayer.fullscreen = YES;
self.moviePlayer.repeatMode = YES;
self.moviePlayer.view.backgroundColor = [UIColor blackColor];
self.moviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.moviePlayer.view.frame = self.containerView.frame;
[self.view addSubview:self.moviePlayer.view];
[self.moviePlayer prepareToPlay];
[self.moviePlayer play];
I have tried using multiple different notifications to see if I can catch this within one of them, but not luck at all. I have tested all of these notifications so far.. I have added this to the self.moviePlayer and also the self.moviePlayer.view not luck in either of them.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(willResignActive:)
name:UIApplicationWillResignActiveNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoStartedPlaying:)
name:MPMoviePlayerNowPlayingMovieDidChangeNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoLoadState:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPlaybackState:)
name:MPMoviePlayerPlaybackStateDidChangeNotification
object:self.moviePlayer.view];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoPlaybackUserInfoKey:)
name:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey
object:self.moviePlayer.view];
Well, if you need more relevant code please let me know. I really need some help with this.. Thanks in advance.
This code worked for me, but just to get rid of freezing. Sign up for the MPMoviePlayerLoadStateDidChangeNotification, like you did above. In the callback method, I simply set the movie players contentURL to the original URL I had initialized it with at the start, and set the movie player to play again.
The functionality of this is when you tap the NEXT or BACK buttons in fullscreen, the video simply starts playing again from the start. That may not be ideal since the user might not expect this, but at least it will stop it from freezing. I'm currently trying to find a better workaround.
- (void) videoLoadState:(NSNotification *)notification
{
MPMovieLoadState loadState = moviePlayer.loadState;
if(loadState == MPMovieLoadStateUnknown)
{
NSLog(#"Movie Load state is unknown");
moviePlayer.contentURL = currentlyPlayingVideoURL;
[moviePlayer prepareToPlay];
}
}
If you check the value of MPMoviePlaybackState in this method, it will always be MPMoviePlaybackStateStopped when NEXT or BACK are pressed, so I'm not sure how to handle it...
I am trying to play video in background.I follow so many tutorial but i did not get appropriate results.For that i am using AVPlayer.I am able to play my video whenever application state is active.But i want to play music in background for that i need to detach AVPlayerLayer from AVPlayer,If you have any alternate solution so that i can play my video in background.Please help me.
This is my code:
ViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];
[[AVAudioSession sharedInstance] setDelegate: self];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
NSURL *url = [[NSBundle mainBundle] URLForResource:#"sample"
withExtension:#"m4v" subdirectory:nil];
avPlayerItem = [AVPlayerItem playerItemWithURL:url];
self.songPlayer = [AVPlayer playerWithPlayerItem:avPlayerItem];
self.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer: self.songPlayer];
self.avPlayerLayer.frame = self.view.layer.bounds;
UIView *newView = [[UIView alloc] initWithFrame:self.view.bounds];
[newView.layer addSublayer:avPlayerLayer];
[self.view addSubview:newView];
[self.songPlayer play];
}
AppDelegate.m
- (void)applicationWillResignActive:(UIApplication *)application
{
ViewController *vc=[[ViewController alloc]init];
vc.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:nil];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
ViewController *vc=[[ViewController alloc]init];
vc.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:vc.songPlayer];
}
You are creating a new view controller in both your application delegate methods, with a new player etc.. That will not change a thing. You must use the player and layer you created in the view controller's viewDidLoad method, and modify that one later in the delegate methods. For this, your application delegate could store the main view controller in it's properties, or you could implement the NSNotifications for application delegate in your view controller class, like so: (could be added to the view controller's viewDidLoad method)
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(appDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(appWillResignActive:) name:UIApplicationWillResignActiveNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(appDidEnterBackground:) name:UIApplicationDidEnterBackgroundNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(appWillEnterForeground:) name:UIApplicationWillEnterForegroundNotification object:nil];
To detach the player layer from the player, as it's said in the documentation, is slightly incorrect, at least confusing. In fact you have to detach the player from the player layer.
Add this code to the applicationDidEnterBackground (not applicationWillResignActive) method:
// Detach player from playerlayer to avoid pause while in background
if (self.playerLayer && self.player)
{
[self.playerLayer setPlayer: nil];
}
In your applicationWillEnterForeground, store a flag to remember that when the application becomes active, it is due to entering the foreground, and not one of the other numerous reasons for which applicationDidBecomeActive may be called:
self.enteringForeground = true;
And then, in your applicationDidBecomeActive: method,
if (self.enteringForeground)
{
// Re-attach player to playerlayer
if (self.playerLayer && self.player)
{
if (self.playerLayer.player != self.player)
[self.playerLayer setPlayer: self.player];
}
self.enteringForeground = false;
}
For this to work, you will need a new property in your application delegate .h file or view controller .h file, depending which implementation you chose:
#property (readwrite) BOOL enteringForeground;
Of course, you also need to add the entry UIBackgroundModes with value 'audio' to your application's info.plist file (or in the Info tab of your project, add the entry 'Required background modes' and then the value 'App plays audio or streams audio/video using AirPlay').
I hope this is helpful. I too struggled at first to implement background playback, and this method seems to work quite well.
I'm new in iPhone Application Development, and now i faced a problem, can any one tell me how can i play a video randomly without pressing the play button. The video should start automatically while the application launch and play randomly without stopping. I don't have any idea how to do this. I don't have any code also. Please help me any one...
Thanks in advanced.
You could implement it like this:
You need a movie player configured with e.g. a file url and add it to your view
NSURL *url = [[NSBundle mainBundle] URLForResource:movieName withExtension:#"mov"];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
moviePlayer.view.frame = // set the frame
[self.view addSubview:moviePlayer.view];
Start the movie player
[moviePlayer play];
Listen to the notification
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handleMoviePlayerStatChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:moviePlayer];
Start the video again
- (void)handleMoviePlayerStatChange:(NSNotification *)note {
NSLog(#"mp playback state %i", moviePlayer.playbackState);
if (moviePlayer.playbackState == MPMoviePlaybackStatePaused) {
[moviePlayer play];
}
}
To hide the video controls set the controlStyle property of the movie player instance:
moviePlayer.controlStyle = MPMovieControlStyleNone;
