// .NAME vtkFFMPEGWriter - 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.
