[FFmpeg-user] FFMPEG not accepting print format string?

Ok, Can give my own answer...

Something was missing before the output path: '-f segment'.
Added that and now it happily creates consecutively numbered segments-
infinitely still but the next step will be to give this a limit where
older files will be deleted.
