Salut Hizoka !
Je viens d'essayer sur ma distrib... Ubuntu 14.04, libav-tools 7:1.2.6-1
Premier essai avec la ligne de commande originale :
bishop@Trusty-14:~/Bureau$ avconv -y -i http://ftvodhdsecz-f.akamaihd.net/i/streaming-adaptatif_france-dom-tom/2014/S48/J4/112832120-20141127-,398,632,934,k.mp4.csmil/index_2_av.m3u8?null= -vcodec copy -acodec aac essai.mkv

[aac @ 0x264a700] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
[aac @ 0x264a700] Alternatively use the non experimental encoder 'libfdk_aac'.
Il ne se passe rien. Par contre il est proposé :
[aac @ 0x264a700] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

Deuxième essai avec l'ajout de -strict -2 dans la commande :
