For those who found this post and still wonder about this:

You need to complie your own FFMPEG engine in order for you to have your own converter on your system/server. This is the guideline for your benefit.

Just “download” the app doesn’t usually work that way, so…if you have time; determination to have the converter yourself; and desire to see it working — then check this link and follow the guideline based on your system (Win/Linux/Mac/etc).

Good luck! 🙂
