Missing ffmpeg

If you are using Windows, the pre-packaged version already contains ffmpeg, no need to handle it. There is an ffmpeg.7z file in the source code, unzip it and place it in the root directory of the software.

If you are using a Linux system, for Debian-based systems, you can use apt-get install ffmpeg, or for Fedora-based systems, use yum install ffmpeg.

For Mac systems, use brew install ffmpeg to install.
