Low disk space + startVideoCapture method returns true

I have a question related to the disk space of an iOS device.

I have an iPod touch device that has no disk space, and when I try to capture video through the camera app, it displays the warning message “There is not enough memory”.

But in my application, if I try to transcode a video using the startVideoCapture method UIImagePickerController, the video does not record. When I run the startVideoCapture method, the application displays the console message "/ var / mobile / Media / PhotoData / capturevideo activity indicator is already cleared".

I'm not sure what that means. When I stop the video recording through stopVideoCapture UIImagePickerController, then it prints a console message " UIImagePickerController: Ignore the request, to stop the video capture, the camera is not currently capturing the video."

I'm not sure why video capture does not happen, or startVideoCapture does not return NO when there is no disk space. I am trying to do this on iPod touch 4th generation with OS version 5.1. Anyone have a problem?

Thanks, Naveen
