title: Issue with OpenCV 3.0 - Recording Video memory leak
body: <p>Sorry, for an old question but I nothing found helful for me. I'm developing an iOS app using OpenCV 3.0 framework. </p>
  
  <p>I'm using cvVideoCamera delgate to record video but as I set <code>_cvVideoCam.recordVideo = YES;</code>, it always gives me memory warning error. 
  If I set <code>cvVideoCam,recordVideo = YES;</code>, Then there is not any memory warning but also the output url always shows (null) at location, on recording finish. </p>
  
  <p>Thanks in advance. </p>
