[Asterisk-video] Anyone knew how to get more than one DTMF under MP4Play

[Liu Jianquan]

I have a 324m video dialplan like blow,

exten => s,1,set(DTMF_INPUT0="")
exten => s,2,mp4play(/usr/video/menu.3gp,'n(6)S(DTMF_INPUT0)s(#)')
exten => s,3,NoOp(${DTMF_INPUT0})

But my menu.3gp file only 2 seconds long ,  so the caller has not enough
time to enter 6 DTMFs,
Do you have any suggestion?
