Пытаюсь создать приложение, которое позволяло бы записывать происходящее на экране с помощью vlc.
Нашлась удобная строчка
/Applications/VLC.app/Contents/MacOS/VLC -I dummy screen:// --screen-fps=25 --quiet --sout "#transcode{vcodec=h264,vb072}:standard{access=file,mux=mp4,dst="Desktop/vlc-output-terminal.mp4"}"
которая позволяет моментально начинать запись. Останов записи - ctrl+c.
Все это прекрасно работает в терминале. Теперь хочу упаковать в приложение.
Нашел вот такое:
https://iswift.org/cookbook/execute-a-shell-command
При запуске получаю
Couldn't posix_spawn: error 1
Вот полный текст ошибки

Погуглил, но что-то с ходу не нашел ни толкового объяснения для macOS, ни как это дело обойти.
В чем отличие между их примером /usr/bin/env и /Applications/VLC.app/Contents/MacOS/VLC ?
