+You're wrong about audiokonverter :
+it uses faac to encode into *.aac files
+I proposed the two patches to have it in Mageia:
+one to build it without using lame and faac for core repo (patent
+problem for both of them)
+one to build it with using lame but without using faac for tainted repo
+(as soon as faac is not provided)
+NB for my personal use I packaged audiokonverter without patch, and
+installed faac from blogdrake's repo !
+
+
+About Arista :
+I tried Arista to create an *.aac file : it complains about missing
+elements...
+Could you really create *.aac files ? or did you only read what it is
+supposed to do.
+Arista uses gstreamer... and, in Mageia, gstreamer-plugins in tainted
+are built without faac, I wonder what is missing on my computer to be
+able to do what you did !!!
+
+
+About Cinelerra and Handbrake : everything is GPL licensed except the
+ISO specification they need to be built ...
+provided as bundled in hanbrake (reason why it was banned from
+Mageia-tainted)
+ and required as BuildRequire : faac-devel for cinelerra, preventing to
+build it for Mageia
+
+And Yes absolutely there's a contamination with a non-free source (how
+the hell an ISO MPEG4 norma could be GPL ?!!!! )
+For example : is UTF8 GPL ? is ISO-8859 GPL : nevertheless you use these
+nonGPL specifications to read this thread in your webbrowser)
+
+
+I don't know actually how to create *.aac files or *.mp4 files with
+Mageia... if you help me I will be happy...
