I was using:
mencoder matrix.mov -ovc xvid -xvidencopts bitrate=1000 -oac faac -faacopts br=128 -of lavf -o output.mp4
I really dunno about faac options and out, but anyway the output.mp4
audio works even if mplayer complains about a lot of problems with audio
FAAD: error: Gain control not yet implemented, trying to resync!

FAAD: error: Maximum number of scalefactor bands exceeded, trying to resync!
FAAD: error: Maximum number of scalefactor bands exceeded, trying to resync!
But this is not the real problem since also in avi it does some messages
but the audio is ok.
Then using -o output.avi (even if lavf) audio and video are there,
in the mp4 I cannot see video, from the log always seams ok but there is
no video displayed:
in stderr, excluding the faad cruft:
VDec: Codec did not set sh->disp_w and sh->disp_h, trying workaround.
