You want to set up your webcam with Linux, see a video stream from it and learn which applications you can use with it, right? Then this article is for you. It has been tested with SUSE Linux 11, but should work for other configurations as well.
The following webcams have been found working with this tutorial:
- Logitech Quickcam messenger

A general list of working webcams can be found at http://mxhaard.free.fr/spca5xx.html.
Load the driver
To find out what driver you need, call
In case of the Logitech Quickcam Messenger the answer will be like:
06: USB 00.2: 0000 Unclassified device [Created at usb.122] UDI: /org/freedesktop/Hal/devices/usb_device_46d_8da_noserial_if2 Unique ID: Eopr.vE+cdFBwClB Parent ID: uIhY.uOe2OKugI8D SysFS ID: /devices/pci0000:00/0000:00:1a.2/usb3/3-1/3-1:1.2 SysFS BusID: 3-1:1.2 Hardware Class: unknown Model: "Logitech QuickCam Messanger" Hotplug: USB Vendor: usb 0x046d "Logitech, Inc."

This means you can install and load the webcam driver like this:
yast -i gspcav-kmp-default modprobe gspca
Now you should see a video device:
ls /dev/video* /dev/video /dev/video0
That means you can install and start your webcam-viewer-software. We choose gqcam:
yast -i gqcam gqcam
It works. You see a video what from what is going on in front of your webcam.
How to use it
- to capture video streams, use the software mencoder:
mencoder tv:// -tv driver=v4l:width=320:height=240:device=/dev/video0 -nosound -ovc lavc -o myvideo.avi
- to do IP phoning, use skype.
- to watch your camera's input, use gqcam.
If you have another webcam, try the above nevertheless. If it does not work, exchange the driver gspca against uvcvideo:
zast -i uvcvideo_kmp_default modprobe uvcvideo
and start gqcam again.
