Everything compiles fine and programs like cheese are flipped but I cannot get skype to flip the image even with LD_PRELOAD. Granted, I am running a 64 bit system so my distro (Arch Linux) offers custom PKGBUILDS for skype<http://aur.archlinux.org/packages.php?ID=7914>and libv4l <http://aur.archlinux.org/packages.php?ID=20859> on 64-bit systems so that could be the problem as well.
