I want to play/pause/stop local audio file. Buttons for all functionalities are different. Check attached screenshot for reference.
Below is my click events,
-(IBAction)click_Play:(id)sender {
NSString *path;
NSURL *url;
//where you are about to add sound
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
path =[[NSBundle mainBundle] pathForResource:#"MySong" ofType:#"mp3"];
url = [NSURL fileURLWithPath:path];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
[player setVolume:1.0];
[player prepareToPlay];
[player play];
}
-(IBAction)click_Pause:(id)sender {
[player pause];
}
-(IBAction)click_Stop:(id)sender {
[player stop];
}
Here, I am facing issue in pause functionality. After pausing the audio when I click on play button again. It start playing from starting and not at the point where I pause it. Any solution?
Thanks in advance!
Change your code to this:
-(IBAction)click_Play:(id)sender {
if (!player)
{
NSString *path;
NSURL *url;
//where you are about to add sound
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
path =[[NSBundle mainBundle] pathForResource:#"MySong" ofType:#"mp3"];
url = [NSURL fileURLWithPath:path];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
[player setVolume:1.0];
[player prepareToPlay];
[player play];
}
else {
[player play];
}
}
Don't create instance of AVAudioSession and AVAudioPlayer again and again in play button action. So, keep it simple, create instance of AVAudioSession and AVAudioPlayer in viewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
NSString *path;
NSURL *url;
//where you are about to add sound
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
path =[[NSBundle mainBundle] pathForResource:#"MySong" ofType:#"mp3"];
url = [NSURL fileURLWithPath:path];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
[player setVolume:1.0];
[player prepareToPlay];
}
-(IBAction)click_Play:(id)sender {
[player play];
}
-(IBAction)click_Pause:(id)sender {
[player pause];
}
-(IBAction)click_Stop:(id)sender {
[player stop];
}
Edit:
Call this method when you what to change track. I'll never recommend to create instance of object again and again
-(void)changeTrackWithPath:(NSString *)path{
AVPlayerItem *playerItem = [[AVPlayerItem alloc] initWithURL:[NSURL fileURLWithPath:path]];
[player replaceCurrentItemWithPlayerItem:playerItem];
[player play];
}
I have an AVPlayer where I want to check if allowsExternalPlayBack is set to false. So in my code I have something like
NSURL *url = [NSURL URLWithString:#"https://www.apple.com"];
AVPlayerItem *item = [[AVPlayerItem alloc] initWithURL:url];
AVPlayer *player = [AVPlayer playerWithPlayerItem:item];
player.allowsExternalPlayback = NO;
When I try to test this in a unit test, even in following code, This does not work.
NSURL *url = [NSURL URLWithString:#"https://www.apple.com"];
AVPlayerItem *item = [[AVPlayerItem alloc] initWithURL:url];
AVPlayer *player = [AVPlayer playerWithPlayerItem:item];
player.allowsExternalPlayback = NO;
XCTAssertFalse(player.allowsExternalPlayback);
Result: allowsExternalPlayback is still YES
Expected result: allowsExternalPlayback is NO (at the point of assertion)
I have a problem i have been trying to solve for a day and i tired of beating my head aaginst the wall. Anyone know how to do this?
Number 1 Works Great
Works Great
- (void) viewDidLoad {
[super viewDidLoad];
NSURL *url = [NSURL URLWithString:#"http://techslides.com/demos/sample-videos/small.mp4"];
AVPlayer *avPlayer = [[AVPlayer alloc] initWithURL:url];
self.player = avPlayer;
[self.player play];
}
Does not work
- (void) viewDidLoad {
[super viewDidLoad];
CKAsset *asset = record[#"VideoFile"];
AVPlayer *avPlayer = [[AVPlayer alloc] initWithURL:asset.fileURL];
self.player = avPlayer;
[self.player play];
}
Does not work
- (void) viewDidLoad {
[super viewDidLoad];
CKAsset *asset = record[#"VideoFile"];
NSString *fileName = record[#"videoFileKey"];
NSData *data = [NSData dataWithContentsOfURL:asset.fileURL];
NSString *cachesDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *path = [cachesDirectoryPath stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.mp4", fileName]];
[data writeToFile:path atomically:YES];
if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {
NSURL *url = [NSURL URLWithString:path];

I have a class that provides a Music Player, compiled under ARC. This is the init code:
- (id) init{
self = [super init];
runningVolumeNotification = FALSE;
MPMusicPlayerController *musicPlayer = [MPMusicPlayerController iPodMusicPlayer];
systemVolume = musicPlayer.volume;
NSString *myExamplePath = [[NSBundle mainBundle] pathForResource:#"servo" ofType:#"mp3"];
AVAudioPlayer* p = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:myExamplePath] error:NULL];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
[p prepareToPlay];
[p stop];
return self;
}
Instruments reports a 100% leak on the line:
AVAudioPlayer* p = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:myExamplePath] error:NULL];
I can't figure out where the problem is!
I want to implement a player that plays sounds and/or music. I have these two methods:
-(void)playSound:(int)soundIndex
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[SoundFxFilenameArray objectAtIndex:soundIndex] ofType:#"mp3"]];
if(FxPlayer)
{
[FxPlayer release];
FxPlayer = nil;
}
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategorySoloAmbient error:nil];
FxPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[FxPlayer play];
}
-(void)playMusic:(NSString *)filename
{
NSURL *url = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:filename ofType:#"mp3"]];
if(MusicPlayer)
{
[MusicPlayer release];
MusicPlayer = nil;
}
MusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[MusicPlayer play];
}
Now, [[SoundPlayer sharedManager] playSound:FXIndex_Default] works just fine. When I try to play music though, [[SoundPlayer sharedManager] playMusic:#"music_file_name_here" just doesn't do anything. Note that both the sound file and the music file are of the same format (mp3).
Also, the "sharedInstance" is because I implemented the singleton pattern for this audio player.
Any pointers or ideas on what is so wrong in my code so that I can play sounds but not music?
Use fileURLWithPath instead of URLWithString in playMusic:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:filename ofType:#"mp3"]];
URLWithString expects a complete URL such as "file://path/to/file.mp3" as argument, fileURLWithPath expects just a file path.
