/** @file    test_vetLinuxMPEGPlayer.cpp
 *
 *  @brief   Testing code for class vetCodec_MPEG and vetWindowQT.
 *
 *           Load first video stream from an MPEG1-2 format file and
 *           show preview in a window , stream is passed through
 *            vetFrameRGB24 objects.
 *           Frame rate should be the higher possible, after 100 frames,
 *           loop will exit printing average fps; this number depends
 *           on source rate and window's redrawing both (sum).
 *           Then last captured frame is saved.
 *
 *  @warning requires VETLib with MPEG support and GUI support (make all)
 *
 *  @see     vetCodec_MPEG
 *  @see     vetWindowQT
 *  @see     app_Video4LinuxPlayer.cpp
 *  @see     app_LinuxMOVPlayer.cpp
 *
 *  @version 1.0.2
 *  @date    11/09/2005
