 place it anywhere except the end it fails the conversion. Maybe it's a bug
 that needs to be fixed.

 Your interpretation of the documentation is backward. This means that if
 you place setsar anywhere *but* at the end the SAR may be changed (as it
 happens in your case, since the scale filter forces the output display
 aspect ratio to be the same as in input, by changing the output SAR).
