I am developing an IPhone app using the SDK but the question is not iPhone specific. Right now I have a test app with code taken from the guide at
http://beta.devworld.apple.com/documentation/MusicAudio/Conceptual/AudioQueueProgrammingGuide/AQPlayback/chapter_4_section_1.html#//apple_ref/doc/uid/TP40005343-CH3-SW1
It was working fine for a while but now it hangs on AudioQueueNewOutput.
I am running from within XCode and click "Run >> Stop" when debugging to start testing again.
<code snippet>
- (void)applicationDidFinishLaunching:(UIApplication *)application {
[NSThread detachNewThreadSelector:@selector(threadWorker:) toTarget:self withObject:nil];
}
- (void)threadWorker:(id)anObject {
bool done;
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
AQPlayerState aqData;
const char *filePath = "/testing.mp3";
CFURLRef audioFileURL = CFURLCreateFromFileSystemRepresentation( NULL, (const UInt8 *) filePath, strlen (filePath), false );
AudioFileOpenURL ( audioFileURL, fsRdPerm, 0, &aqData.mAudioFile );
UInt32 dataFormatSize = sizeof (aqData.mDataFormat);
AudioFileGetProperty ( aqData.mAudioFile, kAudioFilePropertyDataFormat, &dataFormatSize, &aqData.mDataFormat );
CFRelease (audioFileURL);
OSStatus stat = AudioQueueNewOutput ( &aqData.mDataFormat, HandleOutputBuffer, &aqData, CFRunLoopGetCurrent(), kCFRunLoopCommonModes, 0, &aqData.mQueue );
...
...
...
[pool release];
}
</code snippet>
I have a good callback and user data structure.
The mDataFormat looks valid for a mp3.
But now when i try to step over AudioQueueNewOutput, it just hangs.
Rebooting doesn't help. I have even reinstalled the SDK.
iTunes plays audio fine.
Is this a problem with XCode or GDB?
What can I do to reset whatever is stuck and not letting me play sounds.
Thanks for your help,
-Rosco
