usc_camera1394 is a package that is based on cameradc1394, but that provides messages to control the parameters (brightness, whitebalance, etc) of the firewire camera in real-time. This is intended for stationary cameras where auto detection of feature values might disrupt color-finding or background subtraction. Use camera_param_gui to make those changes. Documentation is forthcoming. Most of the dead packages that were a problem with cameradc1394 have been resolved with usc_camera1394. Be aware, the package name is subject to change. Though the list will be posted if it does.
