Не выводится криллица, библиотека stegano по дефлоту в кодировке utf-8, но видимо из-за каких то манипуляций при записи данных в кадр меняется кодировка, и вместо кирилицы выводятся крокозябры в процессе дешифровки, понимаю код большой, но не получается показать минимальным примером, уж извините.(программа шифрует текст в видео mp4 формата)
