The data output  - to 'stdout' - consists of encoded MP3 audio frames (because 
that's what was transmitted (inside RTP packets) by the server).  To 'play' 
this data, you need to feed it into a decoder (which we don't supply).  That's 
what media players (such as VLC, Winamp, etc.) do.

Right now, you can't.  There has been recent work in the IETF to make this 
possible (see <https://ietf.org/doc/draft-ietf-avtcore-idms/?include_text=1>), 
but we don't currently support this.
