You just want to see a video stream from your webcam to verify it is working correctly, right? Then this article is for you.

What to buy

Buy the Logitech Quickcam messenger and install SUSE Linux 11. Other webcams and distributions may work as well, but this article wants to give an exact description about one installation that surely works.

What to call

Install gqcam

yast -i gqcam

call gqcam

gqcam

result:

/dev/video: No such file or directory

=> very poor! It does not even give a recommendation what to do. But we do: Load the webcam driver

modprobe gspca

Start gqcam again. Now 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 watch your camera's input, use gqcam.

If you have another webcam

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.
