Get album artwork from MP3 file/ID3 tag

由 为君一笑 提交于 2019-11-30 17:33:04
问题 I'm trying to get the album artwork from a MP3 file. In this case I use AVAudioPlayer to play the file. Here's the code that I thought would get the album artwork: MPMusicPlayerController *controller = [MPMusicPlayerController applicationMusicPlayer]; MPMediaItem *current = controller.nowPlayingItem; MPMediaItemArtwork *artwork = [current valueForProperty:MPMediaItemPropertyArtwork]; UIImage *artwork2 = [artwork imageWithSize:artwork.bounds.size]; [artworkView setImage:artwork2]; However

问题 I'm trying to automatically play a sound file (that is not part of my app bundle and is not a notification sound) upon receiving a remote notification. I want this to happen whether the app is in the foreground or background when the notification is received. I'm using the Amazing Audio Engine as a wrapper around the core audio libraries. In my App Delegate's didReceiveRemoteNotification I create an Audio Controller and add AEAudioFilePlayer to it like so: NSURL *file = [NSURL fileURLWithPath

AudioToolBox leak in iOS6?

由 喜你入骨 提交于 2019-11-30 17:20:28
问题 When I use AudioToolBox for playing music, memory leaks heavily. AVAudioPlayer *newMusicPlayer = [[AVAudioPlayer alloc] initWithData:data error:&error]; I use this code to play music. In iOS5 and iOS4, it works properly. But in iOS6, if data's size is 5M, all of the 5M leaked. And I can't see leak info in Instruments. Is there anybody have the same problem? Any suggestion will be grateful. All my audio code here(Using ARC): @implementation ViewController { AVAudioPlayer *_player; } - (void

问题 I want to play a specified duration within a sound file on IOS. I found a method in AVAudioPlayer that seeks to the begining of the playing (playAtTime:) but i cannot find a direct way to specify an end time before the end of the sound file. Is there is a way to achieve this? 回答1: If you don't need much precision and you want to stick with AVAudioPlayer , this is one option: - (void)playAtTime:(NSTimeInterval)time withDuration:(NSTimeInterval)duration { NSTimeInterval shortStartDelay = 0.01;

Trying to fix AVAudioPlayer lag on its initial use

This issue has shown up in several other question here on SO: Slow start for AVAudioPlayer the first time a sound is played Delay in playing sounds using AVAudioPlayer I've tried implementing the fixes suggested but none of them are solving my problem. My application presents the user with a grid of objects to touch, when an object is touched a sound is played. This works great except on the initial touch there is a delay of ~2 seconds. To get around this I initialize my audio player with a dummy aiff file: - (void)viewDidLoad{ NSString *soundFile = [Card loadCardSoundPath:@"dummy"];

AVAudioPlayer and AirPlay - possible?

由 折月煮酒 提交于 2019-11-30 15:09:24
I'm trying to ascertain whether it's possible to toggle AirPlay support using the AVAudioPlayer class. From what I have read: AirPlay is a technology that lets your application stream audio to Apple TV and to third-party AirPlay speakers and receivers. AirPlay support is built in to the AV Foundation framework and the Core Audio family of frameworks. Any audio content you play using these frameworks is automatically made eligible for AirPlay distribution. Once the user chooses to play your audio using AirPlay, it is routed automatically by the system. [ Ref ] Based on this info; it should work
