I was wondering, when your first mail came, what you mean. Could you
elaborate what you mean with audio bars? Something like ffmpeg's
showvolume filter?

I can't find an example image of showvolume on the net, but you can try
it for yourself with ffplay:
$ ffplay -f lavfi -i 'amovie=multimediafile.ts,showvolume'

If so, we can show you how to overlay this onto the video stream.
