PlayCap is a simple video capture device previewer. Unlike AMCap, it does
not allow you to capture data to a file. Instead, it searches for the first
available video capture device registered in the system, connects to it,
and begins displaying its video data in a small window.
It demonstrates a simple example of using the ICaptureGraphBuilder2 and
ICreateDevEnum interfaces to build a capture graph. This type of simple
previewing might be used in a videoconferencing application, for example.
