$ mencoder -of avi -o t.avi -oac lavc -lavcopts acodec=libfaac
-ovc x264 -x264encopts bitrate=500:preset=veryfast -tv device=/dev/video-t:norm=PAL-BG:alsa tv://E7
...
Audio LAVC, couldn't find encoder for codec libfaac.

Exiting...
$ dpkg -l | grep aac
ii  faac           1.28-0.3       an AAC audio encoder
ii  libfaac0       1.28-0.3       an AAC audio encoder - library files
