Public Methods

Method	Description
Close ( ) : void
ListVideoSources ( ) : string>.IDictionary	List potential video sources on the system This just adds a default device without checking it's existance on Windows. On Linux this list all /dev/video* devices, and attempts to get their name using /lib/udev/v4l_id, watch the kernel source (link available in source comments) to that this remains compatible. Alternately, define UDEV_RULES and the "/dev/v4l/by-id/" symlinks will be used to find the names. Note this presumably depends on Ubuntu 9.10 udev rules. Thus the other approach is preffered. Note that on Linux this might be solve a lot better using HAL over dbus, however, last I checked HAL is being replaced by DeviceKit which isn't done yet, so unless the APIs are expected to remain stable HAL is a waste of time.
Open ( string device ) : void	Open a video device
ResetLastItemScanned ( ) : void	Resets the last item scanned This method may only be called from UI-thread.
Scanner ( ) : System
