Мощь можества ядер для укрощения кодека AV1

1. Получаем кусочек, сохраняем его в папку
2. Генерим CMD файл с командой для кодирования и удаление самого CMD файла в конце
3. Запускаем CMD файл

1. Есть исходный файл, есть файл результата и есть CMD файл — кодирование еще идет
2. Есть исходный файл, есть файл результата и CMD файла нет — кодирование завершено
