the problem(?) is that they share a lot more.
try to remove a codec file from Makefile, and see how many other
codecs use some code from it. the libavcodec codecs has a lot
cross-dependency on eachother, sharing small helper functions or
sometimes even big parsers (with some if()'s inside to check codec type).
