FFmpeg - Плохой системный вызов

Здравствуйте!

В разделе администрирования, результаты проверки:

Site setup

• Dolphin version = 7.3.3 - OK
• files and folders permissions
  Please click here to find out if dolphin permissions are correct.
• ffmpeg

  Bad system call
  

  if you don't know if output is correct then manual server audit may be reqired.
• mail sending - click here to send test email to no-reply@xxx.com
• cronjobs

  no crontab for www-root
  

  if you are unsure if output is correct then manual server audit may be reqired.

Как это исправить?

По умолчанию поставляется ffmpeg для Linux, на другой системе ffmpeg нужно заменить на другой. 

Для других систем ffmpeg можно взять по следующим ссылкам:

ffmpeg for Windows

ffmpeg for Mac OSX

ffmpeg for Linux

 I have a Linux system

• Web-server: Apache/2.4.10 (Debian)
  • rewrite_module - OK
• OS: Linux vpsxxxxx.hvosting.xx 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2+deb8u1 (2017-06-18) x86_64

Hardware requirements

Hardware requirements can not be determined automatically - manual server audit may be reqired.

I answered your email on this.  You might have to talk with the people providing the server.  I suggest making a backup of your site files and database and copy to your local hard drive since this might be related to a server issue.  If you have to rebuild the server, you would lose all your data.

Thank you all. Now it's all working, downloading videos, audio, video comments, etc.
