I need to stream video and audio on a mac. The mac is already set up with video and audio in; I need to take this input and send it out (across ISDN--2 separate hookups) either right to the internet or to another site where it will be made web-ready. We want to have the live video and audio feed to people's web browsers. We can do the server stuff and the HTML, but need to get the video and audio off the mac in real time. How is this done?
