Description | Use the revInitializeVideoGrabber command to start up video capture capability. You must use the revInitializeVideoGrabber command before using any of the other commands and functions in the Video library. The command does two things:
Once the video grabber is open, you can use the revVideoGrabDialog command to specify where the video camera (or other video source) is connected. Use the revRecordVideo command to record video from the camera to a file, or use the revPreviewVideo command to display video without saving it. To use Video for Windows (on Windows systems), specify "VFW". To close the window and unload the video capture code, you should use the revCloseVideoGrabber command when you're done with video capture.
