No, the configure script is sufficient.

You can do things like:
$ ./configure --disable-everything --enable-protocol=file 
--enable-demuxer=avi --enable-decoder=ac3,mpeg4 
--enable-parser=ac3,mpeg4 --enable-encoder=h26*,pcm*

No, whitelists are only useful if you are 
using the libraries, not if you are using 
the ffmpeg executable.

Please avoid top-posting here, it is considered 
rude, Carl Eugen
