AVCaptureMovieFileOutput - no active/enabled connections

Question

I am trying to record video in my iPhone app using AVFoundation. But whenever I click the Record button app crashes with this message

-[AVCaptureMovieFile

Answer 1

I had the same problem while changing videoDevice activeFormat and later wanted to record video. Because I was using best quality video I had to set sessionPreset to high, like following

_session.sessionPreset = AVCaptureSessionPresetHigh;

and it worked for me! :)
