Unable to play music from using avplayer in iOS? - ios

Question

I am uploading music to server by converting it to NSData. When i upload the file to server then i also save it to document directory.So when i pass the url of any other music file other than i uploaded then it plays music.But when i try to play music file which i uploaded then it does not play the music.Below is the code for that.
Code for play music
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:fileURL];
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];
player = [AVPlayer playerWithURL:fileURL];
[player play];

Answer 1

it may help you
AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:fileURL options:nil];
NSArray *keys = [NSArray arrayWithObject:[NSString stringWithFormat:#"%d",self.indexValue]];
[asset loadValuesAsynchronouslyForKeys:keys completionHandler:
^{
dispatch_async( dispatch_get_main_queue(),
^{
/* IMPORTANT: Must dispatch to main queue in order to operate on the AVPlayer and AVPlayerItem. */
if (![[keys objectAtIndex:0] isEqual:[NSString stringWithFormat:#"%d",self.indexValue]])
{
}
// NSLog(#"&______________________________________________NOreturned");
playerItem = [AVPlayerItem playerItemWithAsset:asset];
if (!player)
{
player=nil;
}
player=[AVPlayer playerWithPlayerItem:playerItem];
[player play];//: Playground - noun: a place where people can play
});
}];
}

There is a redundant reinitialization for the player object.
Do not forget to subscribe for notifications, for instance :
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:nil];
As it was said in comments, download via browser the file using its URL and try to play by regular player.
Or create asset, and asks about it's tracks, duration, playable state.
AVURLAsset *asset = [AVURLAsset URLAssetWithURL:_videoURL options:nil];
NSArray *requestedKeys = #[#"tracks",#"playable",#"duration"];
__weak typeof(self) wSelf = self;
[asset loadValuesAsynchronouslyForKeys:requestedKeys completionHandler:
^{
for (NSString *thisKey in requestedKeys) {
NSError *error = nil;
AVKeyValueStatus keyStatus = [asset statusOfValueForKey:thisKey error:&error];
if (keyStatus == AVKeyValueStatusFailed) {
//Failed here
//return
}
}
if (!asset.isPlayable) {
//not playable....
}
}

I advice you use AVAudioPlayer for playing mp3. And I show you my two swift examples.
The first example when AVAudioPlayer plays mp3 file from NSData
var audioPlayer = AVAudioPlayer()
func playFromCore() {
let object = fetchedResultsController.fetchedObjects!.first as! Song
let file = object.file // This is NSData
AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
AVAudioSession.sharedInstance().setActive(true, error: nil)
audioPlayer = AVAudioPlayer(data: file, fileTypeHint: AVFileTypeMPEGLayer3, error: nil)
audioPlayer.prepareToPlay()
audioPlayer.play()
}
The second example when AVAudioPlayer plays NSURL
func playMusic() {
let url = NSBundle.mainBundle().URLForResource("89", withExtension: "mp3")!
AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
AVAudioSession.sharedInstance().setActive(true, error: nil)
audioPlayer = AVAudioPlayer(contentsOfURL: url, error: nil)
audioPlayer.prepareToPlay()
audioPlayer.play()
}
