Encode failed (error 3).

Кто-нибудь признает эту ошибку и что с этим можно сделать?

Answer 1

Эррно -2

2 ENOENT No such file or directory. 
A component of a specified pathname did not exist, or the pathname was an empty string.

Источник: http://www.freebsd.org/cgi/man.cgi?query=errno&sektion=2.

В данном случае это означало:

• Вы не ввели правильное имя файла или путь к файлу, или
• у вас нет разрешения на чтение из введенного вами файла / пути.

Answer 2

В конечном итоге проблема с разрешениями! Оказалось, что я не был владельцем папки, в которую выводил. Исправление было что-то вроде

chown $USER folder

Answer 3

У меня была такая же проблема, и я смог пройти через сбой, используя "расширенные настройки", чтобы попытаться замедлить процесс.

Кажется, это работает

Я не уверен, что то, что я изменил, может негативно повлиять на качество видео / аудио (очень новичок ;-)
