/**
* @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
