// .NAME vtkFFMPEGWriter - Uses the FFMPEG library to write video files.
// .SECTION Description
// 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
