- % Closes video VW and releases any system resources necessary to access it
- % (e.g. threads, file handles, etc.). Do NOT just clear a videoWriter
- % object without first closing its handle:
- %
- % % BAD code--typically will leak system resources
- % vw = videoWriter(...);
- % ...
- % clear vw; % leaks resources, probably results in a corrupted file
- %
- % % GOOD code
- % vw = videoWriter(...);
- % ...
- % vw = close(vw);
- % clear vw; % okay, but not needed
- %
- % After calling CLOSE, VW should not be used any more.
- % vw = videoWriter(...);
- % vw = close(vr);
- % next(vw); % BAD
- % vw = videoWriter(...);
- % close(vw); % BAD: should reassign result to vw to be safe
- % next(vw); % BAD
