[MEncoder-users] WMV to FLV problem with video

[Francisco Antonio Vieira Souza]

I tried to convert wmv video to flv using 2 command lines, in both
cases the video seems to play too quickly and finishes but the audio
keeps playing normally.

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

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