/** @file    test_vetVideo4Linux.cpp
 *
 *  @brief   Testing code for class vetVideo4Linux.
 *
 *           Connect to first capture device (/dev/video0), print
 *           size, colour depth and palette, capture a frame, print
 *           processing time (milliseconds) and store image to file.
 *
 *  @warning requires VETLib with V4L support
 *           requires a valid capture device, Video4Linux library.
 *
 *  @see     vetVideo4Linux
 *  @see     test_vetVideo4LinuxPlayer.cpp
 *
 *  @version 1.0
 *  @date    5/08/2005
