#include <itkVideoIOBase.h>

Detailed Description

Abstract superclass defines video IO interface.

VideoIOBase is a class that reads and/or writes video data using a particular external technique or external library (OpenCV, vxl). The VideoIOBase encapsulates both the reading and writing of data. The VideoIOBase is used by the VideoFileReader class (to read data) and the VideoFileWriter (to write data). Normally the user does not directly manipulate this class directly.

A Pluggable factory pattern is used. This allows different kinds of readers to be registered (even at run time) without having to modify the code in this class.
