[MEncoder-users] WMV to FLV problem with video

[Francisco Antonio Vieira Souza]

Sorry but I am kinda newbie on mencoder, could you tell me what I have to
change in this command line?

 (I had copied this from somewhere in web)

mencoder -forceidx -of lavf -oac mp3lame -lameopts abr:br=56 -srate 22050
-ovc lavc -lavcopts
vcodec=flv:vbitrate=250:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -vf
scale=360:240 -o Video.wmv.flv Video.wmv

Thank you very much for your reply.
