- % Closes video VR and releases any system resources necessary to access it
- % (e.g. threads, file handles, etc.). Do NOT just clear a videoReader
- % object without first closing its handle:

- % % BAD code--typically will leak system resources
- % vr = videoReader(...);
- % ...
- % clear vr; % leaks resources
- %
- % % GOOD code
- % vr = videoReader(...);
- % vr = close(vr);
- % clear vr; % okay, but not needed
- %
- % After calling CLOSE, VR should not be used any more.
- % vr = videoReader(...);
- % vr = close(vr);
- % next(vr); % BAD
- % vr = videoReader(...);
- % close(vr); % BAD: should reassign result to vr to be safe
