 Hello, "Jorge Peixoto de Morais Neto", thank you very much really. You have given me so much advice .

mencoder -ffourcc DX50 -o /dev/null -ovc lavc -vf scale=400:240,harddup -lavcopts vstrict=0:keyint=32:mbd=2:trell:v4mv:last_pred=3:predia=3:dia=3:cbp:preme=2:vbitrate=512:vpass=1:turbo -oac faac -faacopts br=128 mov.rmvb

mencoder -ffourcc DX50 -o mov.avi -ovc lavc -vf scale=400:240,harddup -lavcopts vstrict=0:keyint=32:mbd=2:trell:v4mv:last_pred=3:predia=3:dia=3:cbp:preme=2:vbitrate=512:vpass=2 -oac faac -faacopts br=128 mov.rmvb

MP4Box -aviraw audio mov.avi

MP4Box -aviraw video mov.avi

mv mov_audio.raw mov.aac

mv mov_video.cmp mov.m4v

MP4Box -add mov.aac -add mov.m4v mov.mp4

The quality of the mp4 file is good, but still can not be played in phone. 
May be the MP4Box was used in a wrong way, anyone who can tell me how to use it correctly . 

Thanks.

Try these options, they have a greater chance of working (see the
documentation for their meaning):
First pass:
mencoder -ffourcc DX50 -o mov.avi -ovc lavc -vf scale=400:240,harddup
-lavcopts vstrict=0:keyint=32:mbd=2:trell:v4mv:last_pred=3:predia=3:dia=3:cbp:preme=2:vbitrate=512:vpass=1:turbo
-oac  faac -faacopts br=128 mov.rmvb

Second pass:

mencoder -ffourcc DX50 -o mov.avi -ovc lavc -vf scale=400:240,harddup
-lavcopts
vstrict=0:keyint=32:mbd=2:trell:v4mv:last_pred=3:predia=3:dia=3:cbp:preme=2:vbitrate=512:vpass=2
-oac faac -faacopts br=128 mov.rmvb
