Tested and functioning. Thanks Deano.
You need to download the FFmpeg packages that i provide here. https://www.cheetahwsb.com/page/downloads
If you have linux, download the linux package. If windows download the windows package.
The zip file should contain instructions on where to upload them, but upload to your site in plugins/ffmpeg
The package contains both ffmpeg and ffprobe. Make sure both are uploaded.
I will adjust the error messages in the modules to be more specific as to what needs to be done.
