-/*
- * FFMpegVideo.h
- * May 2012 Christopher Bruns
- * The FFMpegVideo class is a C++ wrapper around the poorly documented
- * libavcodec movie API used by ffmpeg.  I made extensive use of Nathan
- * Clack's implemention in the whisk project.
- *
- * The FFMpegVideo.h and FFMpegVideo.cpp files depend only on the libavcodec
- * and allied sets of libraries.  To compartmentalize and reduce dependencies
- * I placed the Vaa3d specific use of this class into a separate set of
- * source files: loadV3dFFMpeg.h/cpp
