I'm trying to stream an radio in my app.
I'm using AVAudioPlayer, but I have an error I don't understand :
NSString *urlString = #"http://broadcast.infomaniak.net/radionova-high.mp3";
NSURL *myURL = [NSURL URLWithString:urlString];
NSError *error;
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:myURL error:&error];
if (self.audioPlayer == nil){
NSLog(#"Error loading clip: %#", [error localizedDescription]);
}
else {
self.audioPlayer.delegate = self;
self.audioPlayer.volume = 0.5;
[self.audioPlayer play];
}
And I have the following error :
Error loading clip: The operation couldn’t be completed. (OSStatus error -43.)
Does anyone see what's wrong ?
EDIT :
This is what the Apple docs say:
The AVAudioPlayer class does not provide support for streaming audio
based on HTTP URL's. The URL used with initWithContentsOfURL: must be
a File URL (file://). That is, a local path.
Now what ? :(
download file to document directoty then play file
NSString *urlString = #"http://broadcast.infomaniak.net/radionova-high.mp3";
NSURL *myURL = [NSURL URLWithString:urlString];
NSData *audioData = [NSData dataWithContentsOfURL:myURL];
NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#.mp3", docDirPath , fileName];
[audioData writeToFile:filePath atomically:YES];
NSError *error;
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
if (self.audioPlayer == nil) {
NSLog(#"AudioPlayer did not load properly: %#", [error description]);
} else {
self.audioPlayer.delegate = self;
self.audioPlayer.volume = 0.5;
[self.audioPlayer play];
}

I have an URL which I get from JSON response, When I hit the URL in browser the file is downloaded, Now am wondering how can I play such URL which is a Download URL.I've been looking around many post But none of them could help me.
type of url am getting : http://www.smartivr.in/sounds/voicemail/download/f77245d9-e7ee-4424-850c-6a45022d0a54_1
Below is the code I tried.
NSString *audio=[NSString stringWithFormat:#"%#.mp3",cell.url];
NSLog(#"url:%#",audio);
NSURL *url = [NSURL fileURLWithPath:audio];
NSData *soundData = [NSData dataWithContentsOfURL:url];
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:#"sound.caf"];
[soundData writeToFile:filePath atomically:YES];
NSError *error;
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL
fileURLWithPath:filePath] error:&error];
[_audioPlayer play];
NSLog(#"error %#", error);
Try this:
//download your audio file
NSString *urlString = #"http://www.smartivr.in/sounds/voicemail/download/f77245d9-e7ee-4424-850c-6a45022d0a54_1.mp3";
NSURL *url = [NSURL fileURLWithPath:urlString];
NSData *soundData = [NSData dataWithContentsOfURL:url];
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:#"sound.caf"];
[soundData writeToFile:filePath atomically:YES];
// get the file from directory
NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString *documentsDirectory = [pathArray objectAtIndex:0];
NSString *soundPath = [documentsDirectory stringByAppendingPathComponent:#"sound.caf"];
NSURL *soundUrl;
if ([[NSFileManager defaultManager] fileExistsAtPath:soundPath])
{
soundUrl = [NSURL fileURLWithPath:soundPath isDirectory:NO];
}
// play audio file
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
[audioPlayer prepareToPlay];
[audioPlayer play];
You should download your audio file asynchronously.
Thank You Dipankar Das for you help.
I am posting the whole solution here.
which worked for me absolutely.
NSString *audio=#"http://www.smartivr.in/sounds/voicemail/download/f77245d9-e7ee-4424-850c-6a45022d0a54_1.mp3";
NSURL *url = [NSURL URLWithString:audio];
NSData *soundData = [NSData dataWithContentsOfURL:url];
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:#"sound.caf"];
[soundData writeToFile:filePath atomically:YES];
// get the file from directory
NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString *documentsDirectory = [pathArray objectAtIndex:0];
NSString *soundPath = [documentsDirectory stringByAppendingPathComponent:#"sound.caf"];
NSURL *soundUrl;
if ([[NSFileManager defaultManager] fileExistsAtPath:soundPath])
{
soundUrl = [NSURL fileURLWithPath:soundPath isDirectory:NO];
}
// plau audio file
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayback error:nil];
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
[_audioPlayer prepareToPlay];
[_audioPlayer play];
[_audioPlayer setVolume:5.0];
try use AVPlayer or AVPlayerViewController, you can use direct URL to play mp3 files
even with local file as you will first download it to device, then play from local URL
do not forget that object AVPlayer has to be as property of your Class not local object because of auto-releasing, so declare your player variable in class and set in function not just locally in function and try to play ...
[update]
more details how to do it -> How to play video with AVPlayerViewController (AVKit) in Swift
Here is the mistake
NSString *audio=[NSString stringWithFormat:#"%#.mp3",cell.url];
NSURL *url = [NSURL fileURLWithPath:audio];
I assume that it is a remote url and you cannot treat it as a file url. So you must use
NSURL *url = [NSURL urlWithString:audio];
I have audio player. I download audio in this way
- (void) song{
if (_index == 0) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"1.mp3"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:filePath isDirectory:NO];
if (!fileExists) {
NSString *stringURL = #"https://drive.google.com/uc?export=download&id=0B6zMam2kAK39VHZ1cUZsM3BhQXM";
NSURL *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
[urlData writeToFile:filePath atomically:YES];
}
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:filePath] error:nil];
}
}
But when audio downloading I can’t do anything. User interface stop.
How can download audio and do anything in user interface simultaneously?
Give your method a block to execute when finished, then run the download code in the background. Lets say, for your case the output is a local file with the downloaded content:
- (void)songWithCompletion:(void (^)(NSString *))completion {
NSString *filePath = [self song];
dispatch_async(dispatch_get_main_queue(), ^{
if (completion) completion(filePath);
});
}
Change the song method to return filePath. Don't ever call it directly, only via songWithCompletion.
- (void)song {
// ... your code from the OP
// don't allocate the audio player here, just return the local file
return filePath;
}
Call it like this...
[self songWithCompletion:^(NSString *filePath) {
if (filePath) {
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:filePath] error:nil];
// you should really handle audio player error here, too
} else {
// handle error
}
}];
You are downloading the file in the main thread. you need to make an asynchronous call in order to avoid stopping UI.
-(void)downloadAudio
{
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:#"https://drive.google.com/uc?export=download&id=0B6zMam2kAK39VHZ1cUZsM3BhQXM"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
receivedData = [NSMutableData data] ;
} else {NSLog(#"no connection!");
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(#"Succeed! Received %d bytes of data",[receivedData length]);
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//NSLog(#"%#", [documentPaths objectAtIndex:0]);
NSString *documentDirectoryPath = [documentPaths objectAtIndex:0];
NSString *folderPath = [documentDirectoryPath stringByAppendingPathComponent:#"audioFile.mp3"];
[receivedData writeToFile:folderPath atomically:YES];
NSURL *soundURL = [NSURL fileURLWithPath:folderPath];
NSError *error;
if ([[NSFileManager defaultManager] fileExistsAtPath:folderPath]) {
player = [[AVAudioPlayer alloc]initWithContentsOfURL:soundURL error:&error];
player.volume=0.5;
NSError *error = nil;
if (!error) {
[player play];
NSLog(#"File is playing!");
}
else{
NSLog(#"Error in creating audio player:%#",[error description]);
}
}
else{
NSLog(#"File doesn't exist");
}
}
i'm trying to design audio streaming app everything is working, but i don't know how to download audio file to the device and read it afterword.
Download audio to document directory.
play it back from document directory.
Added code:
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path firstObject];
NSString *filePath = [documentDirectory stringByAppendingPathComponent:#"evet.mp3"];
// UIImage *cellImage = [[UIImage alloc] initWithContentsOfFile:filePath];
NSLog(#"%#",filePath);
NSError *error;
NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:filePath]];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:_objectData error:&error];
[audioPlayer play];
Based on the code you posted try this.
Change
NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:filePath]];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:_objectData error:&error];
to this:
NSURL *fileURL = [NSURL fileURLWithPath:filePath isDirectory:NO];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
AVAudioPlayer wants a URL object (which needs to be a local URL not a remote web address, hence fileURLWithPath:) not the data itself.
You were trying to give the NSData itself to the audio player.
Fetch your audio file in document directory
- (NSString *)getCacheDirectoryPathForAudio:(NSString *)filePath
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it
NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.mp3", filePath]]; //add
return fullPath;
}
Initiate player with file path
NSString *pathToSaveAudioString = [self getCacheDirectoryPathForAudio:#“filename”];
NSURL* url = [NSURL fileURLWithPath:pathToSaveAudioString];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:pathToSaveAudioString];
if (fileExists) {
NSError* error = nil;
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[self.player setDelegate:self];
if(!self.player)
{
NSLog(#"Error creating player: %#", error);
}
}
else
{
NSLog(#“File Not Exist: %#");
}
and play it using
[self.player play];
Use Delegate methods to check status
#pragma mark - AVAudioPlayerDelegate
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
}
- (void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
}
For more details follow

I have simple code
NSData *D = [self FindDatafromDocument:#"ASDF"];
player = [[AVAudioPlayer alloc] initWithData:D error:nil];
[player setDelegate:self];
[player play];
Method
- (NSData *)FindDatafromDocument:(NSString *)Name {
NSData *IMG;
NSError *error;
NSArray *directoryContents = [[NSArray alloc] init];
directoryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[Utility getDocumentDirectory] error:&error];
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"SELF contains[c] %#",Name];
NSArray *ArrImages = [directoryContents filteredArrayUsingPredicate:predicate];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *Doc = [paths objectAtIndex:0];
for (NSString *imageName in ArrImages) {
if ([imageName rangeOfString:#".caf"].location != NSNotFound) {
IMG = [[NSFileManager defaultManager] contentsAtPath:[NSString stringWithFormat:#"%#/%#",Doc,imageName]];
}
}
return IMG;
}
I have used the following code to initialise an AVAudioPlayer object with NSData, which in turn has the data of an mp3 in my main bundle.
NSError *error;
NSString *filePathForBgAudio = [[NSBundle mainBundle] pathForResource:#"beebuzz10" ofType:#"mp3"];
NSData *bgAudioData = [NSData dataWithContentsOfFile:filePathForBgAudio];
bgAudioPlayer = [[AVAudioPlayer alloc] initWithData:bgAudioData error:&error];
bgAudioPlayer.delegate = self;
I have declared bgAudioPlayer in the .h file. But when I checked by setting breakpoint, I found that after this line bgAudioPlayer = [[AVAudioPlayer alloc] initWithData:bgAudioData error:&error]; the bgAudioPlayer is still shown to be nil. But the filePathForBgAudio and bgAudioData are initialised correctly and has data. just the bgAudioPlayer is nil. What is the problem in the above code? How to rectify this?
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"bubble"
ofType:#"mp3"]];
NSError *error;
_audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else
{
_audioPlayer.delegate = self;
[_audioPlayer prepareToPlay];
}
}
- (IBAction)playsound:(id)sender
{
[_audioPlayer play];
}
NSError *error;
NSURL *filePathForBgAudio1 =[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"beebuzz10" ofType:#"mp3"]];
//NSString *filePathForBgAudio = [[NSBundle mainBundle] pathForResource:#"beebuzz10" ofType:#"mp3"];
// NSData *bgAudioData = [NSData dataWithContentsOfFile:filePathForBgAudio1];
bgAudioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:filePathForBgAudio1 error:&error];
I have a UITableView displaying a llist f files in the Documents Directory... and I want it to play the audio file in the Documents directory when pressed...
It runs with no errores but doesn't play the audio when pressed...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fileName = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d.caf",indexPath.row+1]];
NSURL *audioURL = [NSURL URLWithString:fileName];
NSData *audioData = [NSData dataWithContentsOfURL:audioURL];
NSError *error;
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error];
_audioPlayer.delegate = self;
[_audioPlayer play];
}
Change this line:
NSURL *audioURL = [NSURL URLWithString:fileName];
to this:
NSURL *audioURL = [NSURL fileURLWithPath:fileName isDirectory:NO];
And then just do:
if(_audioPlayer == nil)
{
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:nil];
}
else
{
_audioPlayer = [self.audioAlert initWithContentsOfURL:audioURL error:nil];
}
To start out, the best way to declare a files path is this
- (NSString *)docsdir {
return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
}
in your header, declareNSString *Path;
then, declare the path like this when the view loads
Path = [[self docsdir]stringByAppendingPathComponent:[NSString stringWithFormat:#"%d.caf",indexPath.row+1]];
if (![[NSFileManager defaultManager]fileExistsAtPath:Path]) {
[[NSFileManager defaultManager]copyItemAtPath:[[NSBundle mainBundle]pathForResource:[NSString stringWithFormat:#"%d",indexPath.row+1] ofType:#"caf"] toPath:Path error:nil];
}
now to play it, do this
AVAudioPlayer *player = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:Path] error:&error];
player.delegate = self;
[player play];
