Hi, i performed the above steps and when tried to run the following command

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// -tv driver=v4l2:width=640:height=480:fps=25:device=/dev/video0 -vo x11

recorded this error…

So I have found solution Karmic Koala has already instaled gspca driver which does not work with Microdia webcam, therefore after “make” have to be removed old drivers:
make
sudo modprobe -r gspca_sn9c20x
sudo modprobe videodev
sudo insmod ./sn9c20x.ko
strip -g sn9c20x.ko
sudo mkdir -p /lib/modules/`uname -r`/kernel/drivers/media/video/usbvideo/
sudo cp sn9c20x.ko /lib/modules/`uname -r`/kernel/drivers/media/video/usbvideo/
sudo depmod -a

“Hodge,” from my perspective is both genius and magician! From the jungles of northern Thailand, he saved me from a lot of grief. I recently upgraded my wife’s Lenovo laptop to Ubuntu 9.04 and discovered, to my chagrin: No web-cam. Thanks to the “Microdia WebCam (0c45:xxxx) experimental drivers – installation and testing tutorial,” she can now continue video chats with her family and friends in the RP and throughout the Filipino diaspora. I have bookmarked YOUBUNDLE for future research. With deep appreciation from the Oregon coast. ~rc

Hi, thanks for the tutorial, I finish the steps but my camera still not working in cheese, when I try in wxcam, they catch an error in the capture of the frames. This is the error:

An error has occured during frame capture.
Please check the “frame format” options in the preferences menu

I get from the terminal this:

Hi, thanks for posting this tutorial.
I installed the drivers as this tutorial outlines, and the camera gives me an image in cheese and aMSN etc, the only problem is that the image appears to be “zoomed in”. There are more details about the problem and a couple of images to illustrate the problem on the following page:

http://ubuntuforums.org/showthread.php?t=1246399

Do you know what the problem may be?
Thanks.
