I can only advice against that website. libmp4v2-1 is packaged in the
pkg-multimedia team and a clean packaging can be found on  Please consider joining that packaging team and
maintain the packaging for ubuntu there.

The main problem with mp4v2 is its license: MPL. This license prevents
the library to be used from any GPL licensed application. This does not
seem to be a new issue, btw.

My general recommondation for new program that want to decode AAC is to
port them to libavformat/libavcodec.

I'm inclined to suggest to just drop it.
