fwcamtest has three subtests:
Parameter Test--Tests the digital camera parameters such as vid mode and brightness.
Framereceive Test--Initializes the vid mode, framerate and ring buffer capacity parameters, then checks for the frame received.
Display Test--Displays the captured frames. This display test sets up the 1394 bus for asynchronous transfer mode. The display test will only display the frames on the host running the test; it cannot display on a remote host.
