I developed an app which can play mp3 file using Qt4 phonon module. When i execute the app to play some mp3 file, there is always a waring shows that"cannot find Codec ....."(sorry, i cannot remember the total information). I think I must add some Codec to the phonon module to make this mp3 player work. Is that right? And how to handle it?
any help is great, thanks in forward.
