i am getting errors during compilation.

1. yes, it is possible: you have to use DirectShow to do it, instantiate two IGraphBuilder and connect each of them to a different device
2. you have to add an ISampleGrabber filter to each of the two IGraphBuilder: this will give you the ability to grab a frame from the two devices in your code and process them. Anyway, it depends on what you mean with real-time: the two devices are not synchronized each other, then the two frames are not referred to the same time (the maximum time unalignment between the two frames depends on the frame-rate of the two devices)
