 Well as far as I can tell ffmpeg doesn't support eia_608, see the output
 below:

 and also it doesn't support teletext extraction, see this thread, the wtv
 file contains teletext muxed into the ts stream which ccextractor can
 extract, hence I offered this telxcc to provide support to extract AND
 convert teletext and eia_608.
