Error : "using null output device none available"

Hi,

I compiled a streaming client developed by Qt in Ubuntu 12.04
I can watch videos without audio
However, when I want to play a video containing audio, I get this message in the terminal : "using null output device none available"

After a lot of research in the Internet I understood that this is caused by Qt.
However I didn't found the solution

Could you please help me ?
thanks

Met the same problem here.
Have you solved it?

Seems there is no audio codec to handle whatever audio is included with your video stream. However, with precisely zero specific information we are all just guessing.
