Hi


I can use avcon to convert from wma to wav but not to mp3

avconv -i 4_5_2013.wma -b 128k 4_5_3013.wav
works fine

avconv -i 4_5_2013.wma -b 128k 4_5_3013.mp3
Does not work

I get this error:
Encoder (codec id 0) not found for output stream #0:0

Please advise

P.S sound converter works perfectly what do they use ?
