[ubuntu] GUVCVIEWER Settings

view story

http://ubuntuforums.org – I have a Logitech HD Pro Webcam C920 and I have installed on my Ubuntu the guvcviewer. I need help in setting up the guvcviewer? My Webcam is an updated model of the Logitech C910 which was compatible with the uvcviewer lists, so I am assuming the C920 is also good to go?? I see my face when I open the guvcviewer so it must recognize the webcam. I need to know what the settings should be if i am taking just a photo or if i am doing a video? bill23 (Hardware)
