Re: [Motion-user] Problem tracking with Logitech QuickCam Sphere AF

[arno w. <rag...@gm...>]

Ok, now I got it to work :-)

I have found some documentation in this thread that explains how to
use uvcdynctrl:

Somehow I could not figure out how uvcdynctrl needs it's parameters.
Probably it would be good to include some documentation within the
program, so that it will be easier for newbies like me to get the
camera running ?

Here is the documentation again in case somebody else is also looking for it:

The following are my observation. Appreciate any additional info. If
everything is OK, I want to write a small guide for orbit-AF under
opensuse 10.3
