How to solve cam flipped in Linux Asus UL30

One of the Asus UL30/UL80 Launchpad team members has posted the instructions on how to solve the cam flipped issue:
http://lists.launchpad.net/asus-ul30/msg00044.html

echo -e "\n# libv4l PPA\ndeb http://ppa.launchpad.net/libv4l/ppa/ubuntu `lsb_release -c | awk '{print $2}'` main" | sudo tee -a /etc/apt/sources.list
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C3FFB4AA
sudo apt-get update
sudo apt-get install libv4l-0

to start applications you need to preload so:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so your_application_comand<br />

This issue is also seen in Windows 7, which also needs a driver update in different laptop models. The solution above is Linux-specific.
