My Logitech camera (C300) is properly detected and present at /dev/video0. However, by default the image has contrast and saturation set to maximum, which significantly degrades the image quality. I can change the settings using guvcview but after quitting the settings are back to normal (I am using mplayer to capture frames). How can I make the changes I make in guvcview permanent?
It looks like the guvcview's settings are indeed "sticky" - if I open it again, the image stays the same. So it is something the other programs are doing to the initialisation of the webcam (same problem on mplayer and vlc)
