UBUNTU 14.04 cheese booth not detect webcam
- Open Preferences, and change these resolutions to the lowest.
2.Now restart cheese.
3.The webcam should work. Keep increasing the resolution until it stops working again.For many webcams, this limit is 640x480.
I faced similar problem with cheese so I installed GTK UVC Video Viewer. It rich in terms of feature as compared to cheese. You can install it by entering following in terminal:
sudo apt-get install guvcview
UPDATE: Actually, I just found that you need to manually add your user to the audio and video groups. The easiest way is to launch the "users and groups" app and go to manage groups
Original answer:
There seems to be an issue with the permissions on /dev/video*.
They are owned by root with no read/write permissions for regular users. My quick-and-dirty hack was a simple:
sudo chmod 777 /dev/video*
