 It's not obvious from the documentation why this doesn't output anything:

 {{{
 >ffmpeg -loglevel warning -i input.mp4 -vf "showinfo" -f null -
 }}}

 It should be documented that -loglevel must be at least info for showinfo
 to work.  Alternatively, it would be nice if all the extraneous output
 wasn't necessary for showinfo to work...
