Not against it if nobody will bother to implement this on existing 
devices, but since the long term idea is to merge lavd into lavf, I 
assume the entirety of the library's API will be eventually deprecated 
and replaced.
Worth if anything to remove those AVOutputFormat/AVInputFormat function 
pointers, though.
