</I>This is simply not true, there is vo-aacenc and there is also ffaac, both from
ffmpeg.

</I>><i> Binaries of faac ; and vlc, gstreamer-plugins-bad, mencoder, libquicktime

</I>><i> fedora-15-ATrpm repo
</I>><i> plf repo for Mandriva 2010.2 & 2011
</I>><i> etc...
</I>><i>
</I>><i> These are well known and well used third party repositories
</I>><i> I don't know if they they don't respect the GPL (plf didn't ?)

</I>><i> The mageia's tainted repo being a kind of optional repo (some mirrors being

</I>><i>
</I>><i>
</I>><i> But if these rpms can't be provided by Mageia, some unofficial third party
</I>><i> repos will appear
</I>><i> like for other distro (need to create a new plf for Mageia ?)
</I>><i> or let appear a Mageia International Backport or a Thac's Mageia rpm...
