ffmpeg has been a moving target for quite sometime in regards to the
proper way to send options.  If you happen to have the 0.5 version of
ffmpeg, you can try downloading a mostly compatible version of
nuvexport from here.

To get it to run as a user job, you may need a patch from here

I also had to modify it a bit more to get it to recognize my ffmpeg version line
