in short -profile X  sets the profile for all streams, -vprofile X
just for video streams
X  is not valid for aac thus it fails.

Iam not opposed to apply a patch if  someone has one to workaround this
case but it really is the user asking  for something invalid and an
error is not so wrong as a  result
