How can I strip cover art from a .m4a audio file without re-encoding?

Use ffprobe to find out in which stream the cover art is stored.
Then just copy all streams over to a new file exept the cover art 
stream. (using -map)

Or use another tool, for example Ex-Falso with a GUI works on all 
platforms and also has a commandline tool named operon You can just do this:

     operon image-clear <file> [<files>]
