[libav-tools] How to change metadata without creating a new file

Hello,

I want to use avconv to change the metadata of media files. Unfortunately I 
haven't found a way to change the metadata without creating a new file (of 
course `avconv -i test.mp3 -metadata title="test title" -c copy new.mp3` will 
work, but will create a new file).

The command `avconv -i test.mp3 -metadata title="test title" test.mp3` will 
regenerate test.mp3 in  another bitrate. Also `avconv -i test.mp3 -metadata 
title="test title" -c copy test.mp3` does not work, because it destroys 
test.mp3 (the file shrinks down to some kilobyte).

Is there a way to use avconv to change the metadata of a file without creating 
a new one?

Greetings

Chuck
