Hi,

It does not work, the sound is played as usual but the video is not
displayed by mplayer (VLC is able to display the video ...).

Here are the new mencoder settings :
mencoder -vf scale=320:240 -oac faac -of lavf -o r5_mencoder.mp4
r5.mpeg -ovc lavc -lavcopts vqscale=5:aspect=320/240 -lavfopts
format=3gp -faacopts raw

and mplayer always seems to try to display 0x0 image :
Playing r5_mencoder.mp4.
ISO: File Type Major Brand: 3GPP Profile 4
QuickTime/MOV file format detected.
