Fatal Error After Uploading .FLV File

Hello,

Can someone please help me with the following error I get after uploading a .flv extension file:

Fatal error: Cannot instantiate non-existent class: ffmpeg_movie in /home/videos2w/public_html/include/functions_upload.php on line 174

Any help would be greatly appreciated.

Thanks
Have a great day!

This error happens ffmpeg or ffmpeg-php not installed properly on your server. You need to reinstall ffmpeg and ffmpeg-php
