Dear Jean-Paul Saman,

Thanks your reply. For GUI activate PAUSE,PLAY FAST,PLAY SLOW button by b_pace_control flags. So I try to enable it.
I have developed a simple MPEG2 TS streaming server which support interaction for my testing with LSCP. 
Now I want to add the the client control code such as play,pause,stop etc into the button event routine and make them work like local file play.
Where are these places to added my code? I have found PLAY,STOP,but I didn't find where's the PAUSE activation routine?
