After creating the cache directory as instructed in https://github.com/alphacep/vosk-api/issues/1061, I have yet another error about a missing directory:

You need to install ffmpeg

[pzula]

You need to install ffmpeg

from homebrew?

I wonder if I missed this in the installation instructions somewhere?

[nshmyrev]

Yes

[nortikin]

debian kills me apt install ffmpeg:

Следующие пакеты имеют неудовлетворённые зависимости:
 ffmpeg : Зависит: libavcodec58 (= 7:4.1.9-0+deb10u1)
          Зависит: libavdevice58 (= 7:4.1.9-0+deb10u1) но он не будет установлен
          Зависит: libavfilter7 (= 7:4.1.9-0+deb10u1)
          Зависит: libavformat58 (= 7:4.1.9-0+deb10u1) но он не будет установлен
E: Невозможно исправить ошибки: у вас зафиксированы сломанные пакеты.
