avfoundation

I got a weird crash when using AVPlayer to play a remote video. From the crash log on Fabric , the App crash on system thread ( com.apple.avfoundation.playerlayer.configuration ). The crash log is below: Crashed: com.apple.avfoundation.playerlayer.configuration 0 libsystem_kernel.dylib 0x1839ac2e8 __pthread_kill + 8 1 libsystem_pthread.dylib 0x183ac12f8 pthread_kill$VARIANT$mp + 396 2 libsystem_c.dylib 0x18391afbc abort + 140 3 libsystem_malloc.dylib 0x1839e3ce4 szone_size + 634 4 QuartzCore 0x187ed75e8 -[CALayer dealloc] + 72 5 QuartzCore 0x187e75d90 CA::Transaction::commit() + 1052 6

The application currently I am using has a main functionality to scan QR/Bar codes continuously using Zxing library ( http://code.google.com/p/zxing/ ). For continuous frame capturing I used to initialize the AVCaptureSession and AVCaptureVideoOutput, AVCaptureVideoPreviewLayer described in the apple Q&A http://developer.apple.com/iphone/library/qa/qa2010/qa1702.html . My problem is, when I used to run the camera preview, the image I can see through the Video device is much larger (1.5x) than the image we can see through the still camera of the iPhone.

I am trying to record video in my iPhone app using AVFoundation. But whenever I click the Record button app crashes with this message -[AVCaptureMovieFileOutput startRecordingToOutputFileURL:recordingDelegate:] - no active/enabled connections. I know same question asked in SO, but none of its answers helped me. My problem is the same code works with another application perfectly, and when I try using exactly same code in this app - crashes. But still photo capture is working fine. Adding my codes here - please help me, Thanks in advance -(void)viewDidLoad { [super viewDidLoad]; self

I am using AVPlayer to play .m3u8 file. Using AVAssetImageGenerator to extract image out of it using following code : AVURLAsset *asset1 = [[AVURLAsset alloc] initWithURL:mp.contentURL options:nil]; AVAssetImageGenerator *generate1 = [[AVAssetImageGenerator alloc] initWithAsset:asset1]; generate1.appliesPreferredTrackTransform = YES; NSError *err = NULL; CMTime time = CMTimeMake(1, 2); CGImageRef oneRef = [generate1 copyCGImageAtTime:time actualTime:NULL error:&err]; img = [[UIImage alloc] initWithCGImage:oneRef]; It always gives me error : Error Domain=AVFoundationErrorDomain Code=-11800 "The
