I have tried play audio from streaming. It is working fine with some URL but for some with some URL (http://listen.radionomy.com/almightyradiohindi) it fails even player status comes = AVPlayerStatusReadyToPlay. If I put same URL which is not working in browser then there it also does not work. But I think player should not show status as = AVPlayerStatusReadyToPlay. I am facing problem to manage it. For example how to I know for which streaming URL AVPlayer will work or not ?
My code :
-(void)viewDidLoad {
NSURL *url = [[NSURL alloc] initWithString:urlString];
AVAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
AVPlayerItem *anItem = [AVPlayerItem playerItemWithAsset:asset];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
avPlayer = [AVPlayer playerWithPlayerItem:anItem];
[avPlayer addObserver:self forKeyPath:#"status" options:0 context:nil];
}
-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if (object == avPlayer && [keyPath isEqualToString:#"status"]) {
if (avPlayer.status == AVPlayerStatusFailed) {
NSLog(#"\n\n **** AVPlayer Failed ***\n\n");
}
else if (avPlayer.status == AVPlayerStatusReadyToPlay) {
NSLog(#"\n\n **** AVPlayer Ready to Play ****\n\n");
[avPlayer play];
}
else if (avPlayer.status == AVPlayerItemStatusUnknown) {
NSLog(#"\n\n **** AVPlayer Unknown \n\n ****");
}
}
}
when I open your audio url(http://listen.radionomy.com/almightyradiohindi) in browser it will change to (http://streaming.radionomy.com/AlmightyRadioHindi?lang=en-US%2cen%3bq%3d0.8%2cfa%3bq%3d0.6)
if you can get the exact url and url-encode it the problem will be fixed
url encoding in swift 3.0:
var originalString = "test/test"
var escapedString = originalString.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
print(escapedString!)

I'm creating an ios app with a streaming player maded with AvPlayer. This is my code:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self InitPlayer];
[self ReadMetaData];
}
-(void)InitPlayer{
NSURL *url = [[NSURL alloc] initWithString:#"http://www.fakeurl.com/stream"];
// create a player view controller
self.player = [AVPlayer playerWithURL:url];
player.closedCaptionDisplayEnabled = NO;
}
-(void)ReadMetaData{
[self.player.currentItem addObserver:self forKeyPath:#"timedMetadata" options:NSKeyValueObservingOptionNew context:nil];
}
- (void) observeValueForKeyPath:(NSString*)keyPath ofObject:(id)object
change:(NSDictionary*)change context:(void*)context {
if ([keyPath isEqualToString:#"timedMetadata"])
{
AVPlayerItem* playerItem = object;
for (AVMetadataItem* metadata in playerItem.timedMetadata)
{
if([metadata.commonKey isEqualToString:#"title"]){
TitleLabel.text=metadata.stringValue;
}
}
}
}
With this code i can successfully play and pause the stream. I can also print the title of the track.
If i try to log the timedMetadata with something like this:
NSLog(#"%#",player.currentItem.timedMetadata);
I retrive that:
"<AVMetadataItem: 0x15649500, identifier=common/title, keySpace=comn, key class = __NSCFConstantString, key=title, commonKey=title, extendedLanguageTag=(null), dataType=(null), time={21888/44100 = 0.496}, duration={INVALID}, startDate=(null), extras={\n}, value=Keepin-'fake song title>"
Now my question is: for that specific stream url the timedMetadata i logged are the only metadata i can retrive? If yes how i can achive a more complex player type (something like "go to next track button","go to previous track button","an history of tracks",ecc...) ? That's the first time i work with stream data and in my expectations there was a lot of information in audio metadata. In real life seems i can get only the track title. There's a problem with my code or the stream source is poor in metadata info?
I tried to find best solution to get metadata from AVPlayer and found it:
-(IBAction) BtnGoClick:(id)sender {
NSURL *url = [[NSURL alloc] initWithString:#"http://cast.loungefm.com.ua/loungefm"];
[self setupAVPlayerForURL:url];
}
-(void) setupAVPlayerForURL: (NSURL*) url {
AVAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
AVPlayerItem *anItem = [AVPlayerItem playerItemWithAsset:asset];
player = [AVPlayer playerWithPlayerItem:anItem];
[player addObserver:self forKeyPath:#"status" options:0 context:nil];
[anItem addObserver:self forKeyPath:#"timedMetadata" options:NSKeyValueObservingOptionNew context:NULL];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if (object == player && [keyPath isEqualToString:#"status"]) {
if (player.status == AVPlayerStatusFailed) {
NSLog(#"AVPlayer Failed");
} else if (player.status == AVPlayerStatusReadyToPlay) {
NSLog(#"AVPlayer Ready to Play");
} else if (player.status == AVPlayerItemStatusUnknown) {
NSLog(#"AVPlayer Unknown");
}
}
if ([keyPath isEqualToString:#"timedMetadata"])
{
AVPlayerItem* playerItem = object;
for (AVMetadataItem* metadata in playerItem.timedMetadata)
{
if([metadata.commonKey isEqualToString:#"title"]){
NSLog(#"%#",metadata.stringValue);
}
}
}
}
Result:
I am trying to play video with new AVPlayerViewController introduced in XCode 6.
To play video i have done this setup.
Using local mp4 file to play video
Extended AVPlayerViewController
Player setup code :
-(void)setupPlayer
{
NSString* filePath = [[NSBundle mainBundle] pathForResource:#"exodus_trailer" ofType:#"mp4"];
NSLog(#"File Path : %#",filePath);
AVAsset *avAsset = [AVAsset assetWithURL:[NSURL URLWithString:filePath]];
AVPlayerItem *avPlayerItem =[[AVPlayerItem alloc]initWithAsset:avAsset];
self.player = [[AVPlayer alloc]initWithPlayerItem:avPlayerItem];
[self.player addObserver:self forKeyPath:#"status" options:0 context:nil];
[self.player play];
}
KVO handling :
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
if (object == self.player && [keyPath isEqualToString:#"status"])
{
if (self.player.status == AVPlayerStatusFailed)
{
NSLog(#"AVPlayer Failed");
}
else if (self.player.status == AVPlayerStatusReadyToPlay)
{
NSLog(#"AVPlayerStatusReadyToPlay");
[self.player play];
}
else if (self.player.status == AVPlayerItemStatusUnknown)
{
NSLog(#"AVPlayer Unknown");
}
}
}
Issue :
KVO log is printing AVPlayerStatusReadyToPlay and file path seems ok. Previously view was at least showing player with all default controls, but now without any changes it started to show Quick time logo without any control. What is meaning of showing this logo ? what i am doing wrong here ?
Screenshot :
Here is exactly like what you wanted to do. The problem with your code is that you are not using file path, use this to load the file path NSURL *url = [NSURL fileURLWithPath:urlString]
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *urlString = [[NSBundle mainBundle] pathForResource:#"testfile" ofType:#"mp4"];
NSURL *url = [NSURL fileURLWithPath:urlString];
self.player = [[AVPlayer alloc] initWithURL:url];
[self.player addObserver:self forKeyPath:#"status"
options:NSKeyValueObservingOptionNew
context:NULL];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
if (object == self.player) {
AVPlayerStatus status = [change[NSKeyValueChangeNewKey] integerValue];
if (status == AVPlayerStatusReadyToPlay) {
[self.player play];
[self.player removeObserver:self forKeyPath:#"status"];
}
}
else {
[super observeValueForKeyPath:keyPath ofObject:object change:change context:context];
}
}
#end
I am using avplayer for play audio url, but it is not working, I don't know where i am wrong
NSString *radioURL = #"https://www.example.com";
radioPlayer = [AVPlayer playerWithURL:[NSURL URLWithString:radioURL]] ;
// [radioPlayer seekToTime:kCMTimeZero];
NSLog(#"radio player %#",radioPlayer.currentItem);
[radioPlayer play];
Any help would be appreciated.
I strongly recommended the code below to play radio streaming: please take a look also AVPlayer_Class
-(void)Play{
NSString *radioURL = #"https://www.example.com"; //this url must valid
AVPlayer *player = [[AVPlayer alloc]initWithURL:[NSURL URLWithString:radioURL]];
self.songPlayer = player; //self.songPlayer is a globle object of avplayer
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[songPlayer currentItem]];
[self.songPlayer addObserver:self forKeyPath:#"status" options:0 context:nil];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if (object == songPlayer && [keyPath isEqualToString:#"status"]) {
if (songPlayer.status == AVPlayerStatusFailed) {
NSLog(#"AVPlayer Failed");
} else if (songPlayer.status == AVPlayerStatusReadyToPlay) {
NSLog(#"AVPlayerStatusReadyToPlay");
[self.songPlayer play];
} else if (songPlayer.status == AVPlayerItemStatusUnknown) {
NSLog(#"AVPlayer Unknown");
}
}
}
- (void)playerItemDidReachEnd:(NSNotification *)notification {
// code here to play next sound file
}

I had the same issue and just realized that I wasn't retaining the player (using ARC)! So it gets deallocated and stop playing immediately after start.
You need to make sure that you have a strong property radioPlayer and use self.radioPlayer instead of radioPlayer.
You are doing good but your method need to correct on one place.Check using the below method:
NSURL *audioURL = [NSURL URLWithString:radioURL];
NSData *audioData = [NSData dataWithContentsOfURL:audioURL];
self.audioPlayer = [[AVAudioPlayer alloc] initWithData:audioData error:nil];
self.audioPlayer.numberOfLoops = -1;
self.audioPlayer.delegate = self;
[self.audioPlayer prepareToPlay];
self.audioPlayer.volume=1.0;
[self.audioPlayer autorelease];
[self.audioPlayer Play];
and add proper delegate methods for AVAudioPlayer.
Make Sure URL is AddingPercentEscapes.
NSURL *audioURL = // Your Url;
NSString *encodedString = [#"Your Url" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *myURL = [[NSURL alloc] initWithString:encodedString]
AVPlayer *player = [AVPlayer playerWithURL:myURL];
[player prepareToPlay];
player play];
Did you forgot to set the attribute App Transport Security Settings -> Allow Arbitrary Loads (Yes)?
My app currently plays 2 videos at the same time, functionally, but I all the SO answers i've seen utilizes lots of Key-Value code. Is it bad/wrong if I just do the bare minimum listed below?
viewdidload
AVURLAsset *asset = [AVURLAsset assetWithURL:[NSURL URLWithString:firstVideo.videoURL]];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:asset];
self.player1 = [AVPlayer playerWithPlayerItem:item];
[topPlayer setMovieToPlayer:self.player1];
AVURLAsset *asset2 = [AVURLAsset assetWithURL:[NSURL URLWithString:secondVideo.videoURL]];
AVPlayerItem *item2 = [AVPlayerItem playerItemWithAsset:asset2];
self.player2 = [AVPlayer playerWithPlayerItem:item2];
[bottomPlayer setMovieToPlayer:self.player2];
((AVPlayerLayer *)[self.topPlayer layer]).videoGravity = AVLayerVideoGravityResizeAspectFill;
((AVPlayerLayer *)[self.bottomPlayer layer]).videoGravity = AVLayerVideoGravityResizeAspectFill;
[self.player1 play];
[self.player2 play];
The above code is all I use to play a video, and it works fine. Occasionally there is a ~1s delay, how can I wait until both the videos are ready to play, then play them both?
use KVO to observer the player's status, and play videos when both's status is ready.
[yourPlayerItem addObserver:self forKeyPath:#"status" options:NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew context:nil];
and in kvo:
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
if ([keyPath isEqualToString:#"status"]) {
AVPlayerStatus status = [change[NSKeyValueChangeNewKey] integerValue];
switch (status) {
case AVPlayerStatusUnknown:
//do something
break;
case AVPlayerStatusReadyToPlay:
{
//check which avplayer is ready, by check the parametric object isEqual:yourPlayerItem
//use a bool value to record the ready status. after two bools are YES, then play the video
}
break;
case AVPlayerStatusFailed:
{
AVPlayerItem *playerItem = (AVPlayerItem *)object;
[self assetFailedToPrepareForPlayback:playerItem.error];
}
break;
}
}
}
I am implementing AVAudioPlayer to play audio and it works perfectly well while playing files locally stored in the PC.
But when i give the url of some audio file over the internet, it fails sadly.
Here's what the code looks like:
NSString *url = [[NSString alloc] init];
url = #"http://files.website.net/audio/files/audioFile.mp3";
NSURL *fileURL = [[NSURL alloc] initWithString: url];
AVAudioPlayer *newPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error: nil];
Could anybody please point out the problem and what could be done?
Thanks!
Use AVPlayer to stream audio/video based on http url's. It will work fine. AVAudioPlayer is for local files. Here's the code
NSURL *url = [NSURL URLWithString:url];
self.avAsset = [AVURLAsset URLAssetWithURL:url options:nil];
self.playerItem = [AVPlayerItem playerItemWithAsset:avAsset];
self.audioPlayer = [AVPlayer playerWithPlayerItem:playerItem];
[self.audioPlayer play];
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.
I tried other method initWithData on AVAudioPlayer instead of initWithContentsOfURL. First try to get MP3 file into NSData and then play this data.
Look at my code here.
Use AVPlayer and monitor its status to start playback.
Here is a workable example, hope it would be helpful.
#implementation AudioStream
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSString *,id> *)change context:(void *)context

if (context == PlayerStatusContext) {
AVPlayer *thePlayer = (AVPlayer *)object;
switch ([thePlayer status]) {
case AVPlayerStatusReadyToPlay:
NSLog(#"player status ready to play");
[thePlayer play];
break;
case AVPlayerStatusFailed:
NSLog(#"player status failed");
break;
default:
break;
}
return;
} else if (context == ItemStatusContext) {
AVPlayerItem *thePlayerItem = (AVPlayerItem *)object;
switch ([thePlayerItem status]) {
case AVPlayerItemStatusReadyToPlay:
NSLog(#"player item ready to play");
break;
case AVPlayerItemStatusFailed:
NSLog(#"player item failed");
break;
