v4l2ucp

A universal control panel for V4L2 devices

This is port of an original v4l2ucp to Qt4 library. It reads a description of the controls that the V4L2 device supports from the device, and presents the user with a graphical means for adjusting those controls. It allows for controlling multiple devices. There is an easy way to reset one or all the controls to their default state. A list of device files can be given on the command line. If no files are given, the program will check the V4L2UCP_DEV environment variable. If it is set, that file will be opened. Finally, it will try to open /dev/video0 if nothing else was specified. If no devices can be opened, the program will exit.
