/**
 * @class   vtkFFMPEGWriter
 * @brief   Uses the FFMPEG library to write video files.
 *
 * vtkFFMPEGWriter is an adapter that allows VTK to use the LGPL'd FFMPEG
 * library to write movie files. FFMPEG can create a variety of multimedia
 * file formats and can use a variety of encoding algorithms (codecs).
 * This class creates .avi files containing MP43 encoded video without
 * audio.
 *
 * The FFMPEG multimedia library source code can be obtained from
 * the sourceforge web site at http://ffmpeg.sourceforge.net/download.php
 * or is a tarball along with installation instructions at
 * http://www.vtk.org/files/support/ffmpeg_source.tar.gz
