Comment (by BlackScreen):

 I want one picture, one single frame of the whole file - like with
 "showwavespic" or "showspectrumpic". With the ebur128 filter I only get a
 live output of the whole file, not an overview of the whole file.
 If this would be possible with the ebur128 filter, then I would use this.
 But I have no idea how and would be very greatful for a tip. :)
