I have to open camera (by avfoundation.framework)
mac is supported AvCaptureSessionPreset640x480 (FaceTime HD)
I try to do this, but camera image resolution is 1280x720 .
(void)open { captureSession = [[AVCaptureSession alloc]init];
[captureSession beginConfiguration];
....
[captureSession setSessionPreset:AVCaptureSessionPreset640x480];
[captureSession commitConfiguration]; }
why doesn't work avcapturesessionPreeset640x480?
base SDK : OS X 10.9 , OS X Deployment Target OS X 10.7
