// .NAME vtkOggTheoraWriter - Uses the ogg and theora libraries to write video
// files.
// .SECTION Description
// vtkOggTheoraWriter is an adapter that allows VTK to use the ogg and theora
// libraries to write movie files.  This class creates .ogv files containing
// theora encoded video without audio.
//
// This implementation is based on vtkFFMPEGWriter and uses some code derived
// from the encoder example distributed with libtheora.
//
