I've found a Ubuntu user via ubuntuforums.org that have problem with the webcam, the user have integrated webcam - Syntek USB Video Camera. He/she claimed that the webcam image turned upside down. This happen because of the vflip option..
To fix it(Syntek USB Video Camera as a example) you need to know the camera driver, in terminal type :
lsusb
udevinfo --query=all --name=/dev/video0 --attribute-walk
Example udevinfo command result :The driver for the webcam is stk11xx & has the vflip option(To check all the options the driver offers, use the command "modinfo stk11xx")
Now unload the driver and then re-load it with the vflip option, code :
sudo modprobe -r stk11xx
sudo modprobe stk11xx vflip=1
Now try with webcam app to see that the problem has solved. You can add the option to the system settings so the driver always uses it when it loads..
Code:
echo "options stk11xx vflip=1" | sudo tee -a /etc/modprobe.d/options
