Correction :
On MMCameraPickerController.m -> capturePhoto() -> handler of captureStillImageAsynchronouslyFromConnection add :

if(!CMSampleBufferIsValid(imageSampleBuffer)){
             isCapturingImage = NO;
             [self capturePhoto];
             return;
}

EDIT 8NOV2017

         if(!CMSampleBufferIsValid(imageSampleBuffer))
         {
             isCapturingImage = NO;
             [self capturePhoto];
             return;
         }
         
         [_mySesh stopRunning];

And remove [_mySesh stopRunning]; on the -(IBAction)capturePhoto:(id)sender method

Answer 6 · 2017-11-08T12:54:07.000Z

@AzimJavaidKhan It's Camera library issue you can change it with diff camera library and problem solved, It will take time from my end to update the camera library code. You dont have to touch OpenCV code

Answer 9 · 2017-11-08T13:43:04.000Z

@AzimJavaidKhan if you add :

         if(!CMSampleBufferIsValid(imageSampleBuffer))
         {
             isCapturingImage = NO;
             [self capturePhoto];
             return;
         }
         
         [_mySesh stopRunning];

And remove [_mySesh stopRunning]; on the - (IBAction)capturePhoto:(id)sender method ?
