Detailed Description

Superclass of video input devices for VTK.

vtkVideoSource is a superclass for video input interfaces for VTK. The goal is to provide an interface which is very similar to the interface of a VCR, where the 'tape' is an internal frame buffer capable of holding a preset number of video frames. Specialized versions of this class record input from various video input sources. This base class records input from a noise source.

Warning:: You must call the ReleaseSystemResources() method before the application exits. Otherwise the application might hang while trying to exit.
