According to documentation
err = AudioQueueDispose(queue, true);
I use true so dispose of AudioQueue happens immediately, although it does
dispose queue immediately sometimes , other times it has delay 3-4 seconds
up to 13 seconds on the device. err = AudioQueueStop(queue, true) has the
same problem as well.
My understanding is that both functions try to flush-release buffers
already and about to be enqueued...
so I even help my call-back function to flush the buffers if
AudioQueueDispose is going to be called.
static void MyAQOutputCallBack(void *inUserData, AudioQueueRef inAQ,
AudioQueueBufferRef inCompleteAQBuffer)
{
if (player.shouldDispose) {
printf("player shouldDispose !!!!!!!!!!!\n\n\n\n\n\n");
OSStatus dispose = AudioQueueFlush (inAQ);
return;
}
}
Since I am going to record something using AudioQueues after playing a
track, I need this functions returned without delays. couple hundred
milliseconds delay is okay but 3-4 seconds? that is unacceptable.
Other AudioQueue functions also being called on the same thread and they
seem working fine.
I have also tried to call this on main thread to make sure if it is going
to change anything or not
[self performSelectorOnMainThread:@selector(tryOnMain) withObject:nil
waitUntilDone:NO];
or
dispatch_sync(dispatch_get_main_queue(),^{ didnt do any difference
Any idea what might be happening?
