on ubuntu hardy amd64

$ modinfo uvcvideo
filename: /lib/modules/2.6.24-18-generic/ubuntu/media/usbvideo/uvcvideo.ko
version: SVN r215

Any ideas how to get pan/tilt working?

Thank you

Have you imported the logitech.xml file (with the -i option)? In theory the udev script should take care of that but that may not always work (e.g. on certain distributions or if you don't install libwebcam).

Yep, that's all that was needed, silly me.

Thank you Martin.

Hello,

I have a very similar problem. I have a Logitech Quickcam Orbit AF and have installed both the uvc driver and libwebcam with the newest revision and with r178 and cannot get the pan/tilt commands to work in luvcview.

My apologies for a very silly question, but how does one import the logitech file that you are referring to and where do we import it to?

Thanks, Ben

Ben,

if you can't locate logitech.xml file on your system, you can download it from http://www.quickcamteam.net/software/lib...gitech.xml
I am not using r178, looks like the latest (as of few days ago) svn of libwebcam works fine with latest svn uvcviewer

Thanks for the reply. Unfortunately, I am getting this error message with both r178 and the latest versions:

uvcdynctrl: error while loading shared libraries: libwebcam.so.0.1.1: cannot open shared object file: No such file or directory

I have the trunk directory for uvcvideo and the Linux directory for libwebcam in my home folder (on Ubuntu hardy). Is this the correct place to unpack these?

Ben

Please check the ReadMe.txt file about how to properly specify the library path when you install it. In your case, setting the LD_LIBRARY_PATH environment variable to the path where libwebcam is located should do the trick.
