I am trying to play a video in a small area of the screen and record the user's singing at the same time. however it seems the recording is not successful. i have added some code for you to point out possible blunders.
- (void)viewDidLoad
{
[super viewDidLoad];
appDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
NSArray *dirPaths;
NSString *docsDir;
dirPaths = NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
NSString *soundFilePath = [docsDir
stringByAppendingPathComponent:@"sound.caf"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
NSDictionary *recordSettings = [NSDictionary
dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:AVAudioQualityMedium],

[NSNumber numberWithFloat:44100.0],
AVSampleRateKey,
[NSNumber numberWithInt: kAudioFormatLinearPCM],
AVFormatIDKey,
nil];
NSError *error = nil;
[audioRecorder setDelegate:self];
audioRecorder = [[AVAudioRecorder alloc]
initWithURL:soundFileURL
settings:recordSettings
error:&error];
if (error)
{
NSLog(@"error: %@", [error localizedDescription]);
} else {
[audioRecorder prepareToRecord];
}
[self initialiseVideo];
}
- (void) initialiseVideo
{
[audioRecorder record];
NSString *videoName = @"Medium";
NSString *path = [[NSBundle mainBundle] pathForResource:videoName ofType:@"mp4"];
if (path) {

moviePlayer.scalingMode = MPMovieScalingModeFill;

}
I hope this makes sense. The flow does not seem to enter
audioRecorderDidFinishRecording
even after
[audioRecorder stop];
please help. I am searching for this since last 3 days. but no luck :(
