DeskCamera is the secret sauce in this recipe that makes this whole online dueling pinball thing significantly easier. Essentially the program turns all of your video content into IP cameras directly accessible by the host. All audio and video content sources in DeskCamera are assigned the generic term of Media Sources in the application. DeskCamera works great because it will create a separate low-delay RTSP stream for each Media Source without having to juggle multiple application instances
The DeskCamera support team was extremely helpful and responsive, and their development team turned around a new point release that addressed all of the major issues I ran into in about a week and a half.
