Running ffmpeg in exec node not working

@colin, your right...hmmm, I was under the impression that the command parameters needed to be in the 'options'. I ran into something like this a long time ago. I wonder if it changed at some point Iand I missed it (verry likely that I missed it.)

@Metafieldor there is a beta ffmpeg node you might want to look at. see Node-red-contrib-ffmpeg-spawn
