Nextcloud can't find ffmpeg

Help
1

I have a nix file added to my config that creates my nextcloud instance. I also have ffmpeg installed under environment.systemPackages. From the terminal, I can run ffmpeg and it runs just fine. But an app inside Nextcloud (Automated media conversion) relies on finding ffmpeg, and it doesn’t seem to see it. Do I somehow need to add ffmpeg into my nextcloud nix setup for it to find it?

{ config, pkgs, ... }:

{
 
  environment.etc."nextcloud-admin-pass".text = "PWD";
  services.nextcloud = {                
    enable = true;                   
    package = pkgs.nextcloud31;
    hostName = "nextcloud.mydomain.io";
    https = true;
    config.adminpassFile = "/etc/nextcloud-admin-pass";
    config.dbtype = "mysql";
    config.dbuser = "nextcloud";
    config.dbname = "nextcloud";
    config.adminuser = "root";
    configureRedis = true;
  };

  services.mysql = {
    enable = true;
    ensureDatabases = [ "nextcloud" ];
    ensureUsers = [
     { name = "nextcloud";
       ensurePermissions = { "nextcloud.*" = "ALL PRIVILEGES";};
     }
    ];
    package = pkgs.mariadb;
  };

  systemd.services."nextcloud-setup" = {
    requires = ["mysql.service"];
    after = ["mysql.service"];
  };

}

that is weird… it looks like it should work :thinking:

what do your error logs say?

i didn’t realize this ran as a “background job” - that means it isn’t the php-fpm service and environment which executes this command, it is a systemd service

it might be worth a PR to the nextcloud module to unify the environments - in the meantime you can adjust this service in your configuration.nix like so:

systemd.services.nextcloud-cron.path = [ pkgs.ffmpeg ];

i’m somewhat sure that should do it…

alternatively you can set the path of ffmpeg in the settings
