       - Only supported on GNU/Linux (might work on BSD systems too like Mac 
         OS X, but this is untested)
       - See INSTALL.ffmpeg.txt for installation instructions
       - Creates a separate server process to communicate with the
         ffmpeg libraries.  
         - Works when the system's version of GCC is very different from
           the one that MathWorks used to compile Matlab.
         - Isolates ffmpeg errors so they typically cannot crash
           Matlab.
