Hey I'm trying to use video4linux2 to control a Logitech QuickCam Pro 9000. The camera supports UVC and I can get the image just fine. However, I'm having issues with the controls.
Luvcview reports the following controls: V4L2_CID_BASE (predefined controls): index:9963776 name:Brightness type:1 min:0 max:255 step:1 def:128 now:128 index:9963777 name:Contrast type:1 min:0 max:255 step:1 def:32 now:32 index:9963778 name:Saturation type:1 min:0 max:255 step:1 def:32 now:32 index:9963788 name:White Balance Temperature, Auto type:2 min:0 max:1 step:1 def:1 now:1 index:9963795 name:Gain type:1 min:0 max:255 step:1 def:0 now:0 There are no driver specific controls. The problem is that there are some missing. There should also be Auto Exposure on/off, manual exposure, autofocus on/off and manual focus. The strange thing is that luvcview will let me turn off auto exposure (strangely by pressing the on button), and will also let me set the exposure manually. I would like to know if there is a way to access these controls using video4linux? Cheers Michael -- http://www.nicedrums.net The forum for drummers
