i have downloaded some videos in wmv format and i needed to convert them into mp3 to play on my mp3 player. after searching google for how to do this on ubuntu i found a solution:
– first install lame and mencoder:
$ sudo apt-get install lame mencoder
– Run mencoder command to convert wmv file to mp3 file:
$ mencoder audioFileName.wmv -oac mp3lame -ovc frameno -of rawaudio -o audioFileName.mp3
it is too straight and too easy. enjoy your mp3s.
