Not Thread Safe?

Great, Simple, Library. Much appreciated for all your work.

So, I'm not sure this is properly thread safe since, in the constructor for Engine object, it kills any running processes of ffmpeg. If you're currently running a transcoding process and you initiate another instance of Engine in a separate thread, it will kill any existing processes.

Am I missing something?

I have the same issue when extracting multiple thumbnail from a MP4 (in a for loop).
