You just want to see a video stream from your webcam to verify it is working correctly, right? Then this article is for you. It has been tested with SUSE Linux 11 and a Logitech Quickcam messenger, but should work for other configurations as well.
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 do IP phoning, use skype.
- 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.
Note that /dev/video needs to be there, otherwise, no v4l! The driver needs to create it.
To be sure about Vendor and Device IDs, here is a screenshot when calling hwinfo with the Logitech Quickcam messenger:
