ios - AVCaptureSession MaximumDuration -


In my app I'm recording the video for 30 seconds. I used the following line to do this. 

  [imagePicker Set Video Maximum Duration: 30];   
 Everything was working fine then I decided to go from  UIImagePickerController  to  AVCaptureSession , it successfully changed everything Got it, but could not set  MaximumDuration . Is there a parameter / workaround that can set it?   
 
 
  A Wikipedia mofi file output * aMovieFileOutput = [[AVCaptureMovieFileOutput alloc] init]; CMTime maxDuration = & lt; # Create CMTime to represent maximum duration # & gt;; AMovieFileOutput.maxRecordedDuration = maximum speed; aMovieFileOutput.minFreeDiskSpaceLimit = & lt; # Quality and duration of the appropriate minimum film format # & gt ;;
