Use the revCloseVideoGrabber command to free up memory when you're done using the Video library.

Comments:

The Video library loads the operating system's video capture software into memory when you use the revInitializeVideoGrabber command. The revCloseVideoGrabber command unloads this software, freeing up the memory it uses, when you're done.

If your application uses video capture, you should execute the revCloseVideoGrabber command either when your application is finished using video capture, when the stack that uses video capture is closed (in a closeStack handler), or when your application quits (in a shutdown handler).

If the video grabber was already recording video to a file, the revCloseVideoGrabber command stops the recording.

Important! The revCloseVideoGrabbercommand is part of the Video library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone. In the Inclusions section on the General screen of the Standalone Application Settings window, make sure that "Video Grabber" is selected from the list of script libraries.
