Question

I am playing video using this code.

player= [[ MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
player.navigationController.navigationBar.hidden = YES;
player.moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
player.moviePlayer.controlStyle = MPMovieControlStyleNone;
player.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
player.moviePlayer.fullscreen = NO;
[self presentModalViewController:player animated:NO];

Video playing works perfectly But the problem is that after finishing play i am getting this result in console.

[MPAVController] Autoplay: Likely to keep up or full buffer: 0
[MPAVController] Autoplay: Skipping autoplay, not enough buffered to keep up.

and then after i am trying to record the voice but unable to record.

can anybody help me to solve this issue.

same kind of task is done by me… you can take refernce of my code… i hope it helps…

- (IBAction) startRecording:(id)sender
{

    NSLog(@"**************Recording start**************");    

    NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];

    // We can use kAudioFormatAppleIMA4 (4:1 compression) or kAudioFormatLinearPCM for nocompression
    [recordSetting setValue :[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey];

    // We can use 44100, 32000, 24000, 16000 or 12000 depending on sound quality
    [recordSetting setValue:[NSNumber numberWithFloat:41000.0] forKey:AVSampleRateKey];

    [recordSetting setValue:[NSNumber numberWithInt: kAudioFormatAppleLossless] forKey:AVFormatIDKey];

    // We can use 2(if using additional h/w) or 1 (iPhone only has one microphone)
    [recordSetting setValue:[NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey];

    [recordSetting setValue:[NSNumber numberWithInt:16] forKey:AVEncoderBitRateKey];

    NSError *error;

    if (![[NSFileManager defaultManager] fileExistsAtPath:mediaPath])
    {
        [[NSFileManager defaultManager] createDirectoryAtPath:mediaPath withIntermediateDirectories:NO attributes:nil error:&error];
    }


    mediaPath = [[NSString stringWithFormat:@"%@/sound.caf", DOCUMENTS_FOLDER] retain];
    NSURL *url = [NSURL fileURLWithPath:mediaPath];
    NSLog(@"AUDIOPATH%@",mediaPath);
    err = nil;
    NSData *audioData = [NSData dataWithContentsOfFile:[url path] options: 0 error:&err];

    if(audioData) {

        NSFileManager *fm = [NSFileManager defaultManager];
        [fm removeItemAtPath:[url path] error:&err];

    }

    err = nil;
    audioRecorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSetting error:&err];

    if(!audioRecorder){

        NSLog(@"audioRecorder : %@ %d %@", [err domain], [err code], [[err userInfo] description]);
        UIAlertView *alert =
        [[UIAlertView alloc] initWithTitle: @"Warning"
                                   message: [err localizedDescription]

                         otherButtonTitles:nil];
        [alert show];
        return;
    }

    //prepare to record
    [audioRecorder setDelegate:self];
    [audioRecorder prepareToRecord];

    audioRecorder.meteringEnabled = YES;

    BOOL audioHWAvailable = audioSession.inputIsAvailable;

    if (! audioHWAvailable) {

        UIAlertView *cantRecordAlert = [[UIAlertView alloc] initWithTitle: @"Warning"
                                                                  message: @"Audio input hardware not available"
                                                                 delegate: nil cancelButtonTitle:@"OK"
                                                        otherButtonTitles:nil];
        [cantRecordAlert show];
        [cantRecordAlert release];
        return;
    }

    // start recording
    [audioRecorder record];
}
