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.

Tested webcams

The following webcams have been found working:

    Driver Activation Cmd: "modprobe gspca"
  Config Status: cfg=new, avail=yes, need=no, active=unknown       
  Attached to: #20 (Hub)

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 streamer.
  • to do video conferences, use ekiga.
  • to do IP phoning, use skype.
  • to watch your camera's input, use gqcam.

Other webcams

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.
