/**
 * @class   vtkOggTheoraWriter
 * @brief   Uses the ogg and theora libraries to write video
 * files.
 *
 * 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.
