Skype webcam on 64 bit ubuntu

After a bit of searching, I think I've got to the bottom of my built in isight camera not working with skype. The problem was that I didn't have the 32 bit libraries installed. To resolve, perform the following:

1. sudo apt-get install lib32v4l-0 libv4l-0
2. Create a wrapper script within ~/bin/skype_wrapper/skype_wrapper.sh for starting skype containing the following:
#!/usr/bin/env bash LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype
3. Within a terminal, run the following:
chmod +x ~/bin/skype_wrapper/skype_wrapper.sh
4. You can then start skype by running the following from a terminal:
~/bin/skype_wrapper/skype_wrapper.sh
