Hello,  
I installed NextCloud Web Server on a Synology NAS,  
I can’t get previews for video files.

I installed ffmepg7,  
installed the preview plugin,  
specified the path to ffmepg in NextCloud’s config.php,  
and run the command via SSH to generate the previews, which worked with images and documents.
