Hi, I want to know how did vlc know that it must use livedotcom demux when user clic on the rtsp radio button on the gui. Is it right that vlc looks for installed demux through the their description part "vlc_add_module();" then it checks if it's the appropriate one to the selected radio button (i.e, through rtsp-caching or udp-caching... gui case). Thank you very much ------------------------------------------------------------ http://Game.37.com/ <--- Free Games http://newJoke.com/ <--- J O K E S ! ! !
