Video Saving in the wrong orientation AVCaptureSession

Question

I\'m trying to record a video (without displaying the camera) and save it. But the video being saved is not saving in the right orientation. I\'ve tried forcing the UIViewCo

It turns out you have to add the connections' orientation to the AVCaptureMovieFileOutput after it is added to the session.

session = [[AVCaptureSession alloc] init];
[session beginConfiguration];
session.sessionPreset = AVCaptureSessionPresetHigh;


AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
for (AVCaptureDevice *cam in [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo])
{
    if (cam.position == AVCaptureDevicePositionFront)
        device = cam;
}

NSError *error = nil;
AVCaptureDeviceInput *input = [AVCaptureDeviceInput deviceInputWithDevice:device error:&error];
if (!input) {
    // Handle the error appropriately.
    NSLog(@"ERROR: trying to open camera: %@", error);
}

AVCaptureDevice *audioDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeAudio];
AVCaptureDeviceInput * audioInput = [AVCaptureDeviceInput deviceInputWithDevice:audioDevice error:nil];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];


NSString *outputpathofmovie = [[documentsDirectoryPath stringByAppendingPathComponent:@"RecordedVideo"] stringByAppendingString:@".mp4"];
outputURL = [[NSURL alloc] initFileURLWithPath:outputpathofmovie];

[self deleteTempVideos];

[session addInput:input];
[session addInput:audioInput];
[session commitConfiguration];
[session startRunning];

movieFileOutput = [[AVCaptureMovieFileOutput alloc] init];
[session addOutput:movieFileOutput];

AVCaptureConnection *videoConnection = nil;

for ( AVCaptureConnection *connection in [movieFileOutput connections] )
{
    NSLog(@"%@", connection);
    for ( AVCaptureInputPort *port in [connection inputPorts] )
    {
        NSLog(@"%@", port);
        if ( [[port mediaType] isEqual:AVMediaTypeVideo] )
        {
            videoConnection = connection;
        }
    }
}

if([videoConnection isVideoOrientationSupported]) // **Here it is, its always false**
{
    [videoConnection setVideoOrientation:[[UIDevice currentDevice] orientation]];
}

[movieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self];
