The only non-free and non GPL part of FAAC is the ISO MPEG reference
it is based on... to comply with this international standard (nothing
strange in that)
everything else is LGPL .
An international standard may not be modified, for sure, and is surely
not GPL !
And for this reason we may consider FAAC as non-free...
Faac i's the only way to create *.aac or *.m4a files without using a
(like NERO aac encoder that can't be distribuable... and is surely not
But this may induce some patent problems (same as creating *.mp3 files
So FAAC needs to go in tainted ...
What to do with this f****g non-free & tainted program

Binaries of faac ; and vlc, gstreamer-plugins-bad, mencoder,
libquicktime built with faac-devel
are available in :
plf repo for Mandriva 2010.2 & 2011
These are well known and well used third party repositories
I don't know if they they don't respect the GPL (plf didn't ?)
The sources of these programs have some building options (allowing to
patent legislation in some countries...) and the distributions that want
to be worldwide
reachable skip some of these options to build the binaries in their
letting third party providing the "full binaries" with patent potential
The mageia's tainted repo being a kind of optional repo (some mirrors
being free not to propose
it to respect local patent legislation) may be used the same way as
these third repo...
But if these rpms can't be provided by Mageia, some unofficial third
party repos will appear
like for other distro (need to create a new plf for Mageia ?)
or let appear a Mageia International Backport or a Thac's Mageia rpm...
