That's not an option.
I'm not breaking anything. All apps will still work. One option (and it depends on whether people like it or not) is to have audio.h, video.h and osd.h just include av7110.h and add a #warning that these headers need to be replaced by the new av7110.h. And really remove them at some point in the future. But the important thing to realize is that the ABI hasn't changed (unless I made a mistake somewhere).
