        //! Implementation of the CaptureDevice for IEEE 1394 AV/C-devices under linux.

        /*! Such devices don't have controls, various resolutions, extensions, or connectors.
         * So the implementation of the methods rely mostly on the default implementations or are
         * implemented as noop.
         *
         * Note: If capturing from AV/C-devices is enabled, avcap depends on
         * libiec61883, libavc1394, librom1394, libraw1394
         * Furthermore the user requires read/write access to /dev/raw1394.
         *
         * AV/C-support is enabled by the configure-script, if the neccessary libs and developement-headers
         * are found on the system.
         *
         * The AV/C-support is based on dvgrab (http://www.kinodv.org), which is released under the GPLv2.
