Hmmmm. I've just checked out API documentation of libdvdcss.
Sample code:

dvdcss = dvdcss_open( ppsz_argv[1], DVDCSS_INIT_QUIET );
dvdcss_seek( dvdcss, i_sector );

As you can see with libdvdcss you MUST know the starting sector of the
object as well ... The API is block oriented and there is NO option for
opening a FILE. So without an IFO parser we must use FIBMAP with libdvdcss
too ... ANd I've got the bad feeling that I cannot controll authentication
and descrambling freely enough with libdvdcss compared to use libcss.
