QTKit input device.
-The filename passed as input is unused. The default device will be chosen.
+The filename passed as input is parsed to contain either a device name or index.
+The device index can also be given by using -video_device_index.
+A given device index will override any given device name.
+If the desired device consists of numbers only, use -video_device_index to identify it.
+The default device will be chosen if an empty string or the device name "default" is given.
+The available devices can be enumerated by using -list_devices.
