 |
|
I've run out of ideas on how to gain control on the focus of my Logitech cam.
The closest I have come across for a similar camera is here http://dickmcjohnnson.blogspot.com/2011/07/logitech-webcam-pro-9000-running-under.html
Unfortunately uvcdynctrl is no longer in gentoo (nor available anywhere?) as part of libwebcam.
Supposedly guvcview is supposed to have the same kind of function, however even running it as root I cannot get the focus controls to show up.
Has anyone with a software focus controlled cam figured this out? |

Here is the output from "modprobe uvcvideo trace=15"
It seems the driver is not even adding the necessary controls to begin with
