That's compressed audio files (for ipod for instance)
That's also the audiotrack format for MPEG4

Do you mean transcode video with aac audio track into other format
(that's already allowed, thanks to faad provided by Mageia)
or transcode an existing video (with mp3 audio track for instance) into
video with aac audio track (that is not allowed with Mageia2 whichever
software you use : avidemux, vlc, mencoder, gstreamer, ffmpeg)

So you use cauldron ;)

Mageia2 has arista 0.9.7.2
I have too libavcodec from tainted, libvo-aaenc, gstreamer-ffmpeg (can't
find any gstreamer-libav on Mageia2)
Is the new built gstreamer on cauldron allowing to create mp4 or aac
files now ?

Perhaps Cauldron provides something now for this aac encoding problem...
that's  good news for Mageia3
but I will have to wait and see : I must use the stable Mageia2 on my
everyday computer... (with some workarounds ;)  ) until Mageia3 appears
