This guide will help you set up your webcam under SuSE and OpenSuSE 11.0. SuSE doesn't include the main drivers used by most webcams so we will be installing these drivers.
Most webcams are covered by either the Gspca or Linux-uvc driver, we will be covering both.
While this guide is mainly focused to laptop users there isn't any difference for desktop users.
Both the Gspca and Linux-uvc drivers are in a development stage. This means the drivers are not yet considered fully stable and should be installed with caution. This is especially true for the Linux-uvc driver as it is still listed as being in alpha stage.
You should run a full update for your installation to ensure you have all the latest packages installed.
In Linux there are 2 different drivers which covers the majority of webcams available, these are the Gspca or Linux-uvc driver. You will need to determine which is the correct driver to install. If you are not sure which webcam you have you can make use of the 'lspci' and 'lsusb' commands to print a list of devices on your system.
After determining your webcam type you need to see which driver supports your webcam. Here is a list of webcams supported by the Gspca driver and here is a list of webcams supported by the linux-uvc driver.
If you webcam doesn't appear on either list then it's possible your webcam isn't supported. If you like you can just try installing both drivers anyway and see how you go.
In this section we will be detailing the procedure of installing the latest Gspca driver for SuSE-OpenSuSE 11.0.
1. Download the latest drivers from http://mxhaard.free.fr/download.html. You want to download the latest gspcav1 driver, not the older spca5xx. In this guide we are going to use gspcav1-20071224 as at the time of writing these are the current ones.
2. Load up a terminal window if you are in the graphic interface.
3. Switch to the root user by entering the command “su -” (without the quotes) and typing in your root password.
4. Type in the following to install gcc and the kernel headers:
yast -i gcc linux-kernel-headers kernel-headers kernel-source
5. Move to the /usr/src/ folder with:
cd /usr/src
6. Extract the contents of the file you downloaded with:
sudo tar -xzvf /path/to/gspcav1-20071224.tar.gz
Remember to replace the ”/path/to” in this command to the path of where your file is and change the filename to the version you downloaded
7. Move into the newly created folder with
cd gspcav1-20071224
8. Now start the building process with:
make
This will take a while.
9. And finally we install the driver with:
make install
10. Reboot your computer and the newer gspca driver will be used.
In this section we will be detailing the procedure of installing the latest Linux-uvc driver for SuSE-OpenSuSE 11.0.
1. Load up a terminal window if you are in the graphic interface.
2. Switch to the root user by entering the command “su -” (without the quotes) and typing in your root password.
3. Type in the following to install gcc, svn and the kernel headers:
yast -i gcc linux-kernel-headers kernel-headers kernel-source subversion
4. Move to the /usr/src/ folder with:
cd /usr/src
5. Download the latest driver with:
svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
6. Move into the newly created folder with
cd trunk
7. Now start the building process with:
make
This will take a while.
8. And finally we install the driver with:
make install
9. Reboot your computer and the newer linux-uvc driver will be used.
Discussion
i installed the Suse 11. but the webcam is not working. can anybody have some idea about it…………..
Have you tried plugging it in ?
The description you made is valid for kernels 2.6.18 and under (Maybe some above.), when you try to compile it with newer versions, you get errors. There are some patches but in my case that didn't work.
But if you have a more recently kernel 2.6.27 or above, then, gspca webcam code has been fused with the kernel, so webcam is supported directly and you just need the right packages.
In my case, i'm running OpenSusse 11.1, i installed the following packages:
kernel-default
kernel-default-base
kernel-default-devel
kernel-source
kernel-syms
linux-kernel-headers
webcam-gspca2-kmp-default
for the kernel 2.6.31. Yast builds automatically the webcam support.
Some applications like skype 2.0.1.81 will need v4l, so, i installed:
libv4l
libv4l-devel
v4l-conf
v4l-tools
Aditionally, just for the first tests, i installed:
gqcam
Cheers.
Hiya, I am really glad I've found this info. Today bloggers publish only about gossips and internet and this is really annoying. A good website with interesting content, this is} what I need. Thanks for keeping this website, I will be visiting it. Do you do newsletters? Can not find it. horoscope pas cher http://astrologiegratuite.eu
My webcam doesn't work after the SUSE installation. I use OpenSuSE 11.3. I gave 'lsusb' cmd in a su window. The result was 'Microdia laptop integrated webcam 1.3M' , '/dev/input/event11' , 'device id: 222237' , 'kernel driver: uvcvideo'. Which are the values of operands existing in the below command ? I refer to this command:
yast -i gcc linux-kernel-headers kernel-headers kernel-source subversion
I'm not a gcc (C++) developer!
Last question: can you attach in the next OpenSuSE kernels (11.3, 11.4 …) the most popular drivers belonging to the uvcvideo class drivers ? I think the kernel's size doesn't increase dramatically.
a specific info is needed to the above message: I use a Dell srs premium sound. I preferred the OpenSUSE 11.3, 32-bit version instead of 64-version. So it is an i586, KDE kernel 4.4.4 “release 2”. The gcc 45 compiler is installed at minimum level already.

By Dell srs premium sound, you mean Dell Inspiron 1564 SRS Premium Sound?
KDE and kernel are different. By 4.4.4 i think you mean KDE release.
Checking kernel version is easy, just type
$ uname -a
The gcc version should be ok if you have a new installation.
“My webcam doesn't work after the SUSE installation.”
What program are you using to test video? (I may suggest something simple like cheese)
“I use OpenSuSE 11.3. I gave 'lsusb' cmd in a su window. The result was 'Microdia laptop integrated webcam 1.3M' , '/dev/input/event11' , 'device id: 222237' , 'kernel driver: uvcvideo'.”
I've moved to Debian and Ubuntu, but this is what I know about it.
Strange result from #lsusb. The ID is supposed to be in hexadecimal format, like this in my case:
$lsusb
Bus 002 Device 003: ID 03eb:2104 Atmel Corp. AVR ISP mkII
if you need to look for your device ID, here is a list
http://www.linux-usb.org/usb.ids
There you can see for example that 03eb belongs to ATMEL and 2104 to the AVR ISP mkII programmer.
About the kernel driver… well, I have tried before with uvcvideo but it didn't work, that's why I ended installing all related v4l packages. Some programs needed to PRELOAD the driver before the program call, like this:
LD_PRELOAD=/usr/local/lib/libv4l/v4l1compat.so skype
in the ”.bash_profile” file, that I have posted here
http://forum.skype.com/index.php?showtopic=476781
“Which are the values of operands existing in the below command ? I refer to this command:
yast -i gcc linux-kernel-headers kernel-headers kernel-source subversion”
It is great that you wanted to install it from console, but it is easier to open Yast and look for the right packages inside the window. Install the most recent (it might not be the best solution because i have had problems with kernel 3.x.x in an older laptop, but it is supposed to work well). Have a look on the list I just posted before.
“Last question: can you attach in the next OpenSuSE kernels (11.3, 11.4 …) the most popular drivers belonging to the uvcvideo class drivers ? I think the kernel's size doesn't increase dramatically. ”
Sorry, I'm neither a developer, but as far as i remember, modules (modules here is equivalent to drivers) support is included in kernel 2.6.27 and above. So that might be the problem, have a look on the webcam manufacturer webpage just in case they have already mentioned something about Linux support. Otherwise here is another thread that might be useful

Thanks for your operative answer. But I am a traditional OpenSUSE versions' user.
The “11.3” works very well on my PC. The web cam is not so stringent because I use an old photo camera. To transpose the films on disk, I use a USB scanner. Unfortunately, the 35 millimeters Kodak films, bought from hypermarkets, are a little bit staled. As a consequence, the clarity of pictures are not so good. The granulation of films are quite superior to the digitized photos obtained by cheap compact cameras.
