For files of captured video containing teletext, there is ccextractor to pull it out: https://ccextractor.org/public/general/whatsccextractor/ https://ccextractor.org/public/general/whatsccextractor/ I've never tried ccextractor for pulling teletext but I use it for pulling almost any kind of closed captions.
