У вас есть несколько подвопросов, связанных с вашим вопросом.
1) Как мне получить все файлы в папке, включая подпапки
2) как мне отфильтровать этот список, чтобы включить только видео файлы
3) Как я могу просмотреть этот список видеофайлов и извлечь информацию из каждого и
4) Как мне преобразовать секунды в полезную строку слов
Обычно я бы попросил, чтобы вы разбили его на эти отдельные вопросы, потому что для кого-то большая задача написать все это для вас. Однако в этом случае вам повезло, потому что я сделал это раньше себя ... так что вы можете получить мой сценарий. Я поместил много комментариев в коде, чтобы помочь вам узнать, как он работает.
