| − | <metadesc>Here is how you set up your webcam with Linux, capture videos and images, do VoIP calls and automate recording. Tested with SUSE Linux, Ubuntu and Debian.</metadesc>
| + | You've really helped me undrtseand the issues. Thanks. |
| − | 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. | |
| − | | |
| − | = Setup =
| |
| − | * plug in your webcam (typically to USB)
| |
| − | * [[open a console]] and list your video4linux devices:
| |
| − | ls -ltr /dev/video*
| |
| − | * you will find an output like this:
| |
| − | crw-rw----+ 1 root video 81, 0 Nov 11 09:06 '''/dev/video0'''
| |
| − | In this example your webcam device is named ''/dev/video0''. If you have no /dev/video file, read [[#Troubleshooting]]. If you have several video4linux devices, for example a [[tv card]] your webcam may show up as /dev/video1 or whatever. But the time (in this case Nov 11 09:06) will be the time when you plugged it in.
| |
| − | * test the webcam
| |
| − | ** if you have [[vlc]] installed you can start it and choose Media -> Open Capture Device -> Video device name = ''/dev/video0'' -> Play
| |
| − | ** if you have mplayer installed you can use the command
| |
| − | [[mplayer]] tv:// -tv driver=v4l2:width=640:height=480:device=''/dev/video0'' -fps 30
| |
| − | | |
| − | Wowza, problem solved like it never haneeppd.
| |
| − | | |
| − | = Troubleshooting =
| |
| − | Troubleshooting heavily depends on the distribution and version you are using. If you have done cabling correctly and a device file /dev/video* does not appear, your kernel probably does not know the hardware. In this case you may have to install the device driver separately because it may not be part of the kernel.

| − | == SUSE Linux 11.0 and earlier ==
| |
| − | This has been tested with SUSE Linux 11.0 x64 but should work with any earlier SUSE version. You will need to log in as user root.
| |
| − | To find out what driver you need, [[open a console]] and call
| |
| − | [[hwinfo]] --usb
| |
| − | If a Logitech Quickcam Messenger is plugged in the answer will be like:

| |
| − | 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.
| |
| − | | |
| − | == Ubuntu ==
| |
| − | This has been tested with Ubuntu 8.10 x32 but should work with any Ubuntu version.
| |
| − | Find out the driver activation command of your webcam. For this, first install the software '''hwinfo'''. [[Open a console]] and type:
| |
| − | sudo apt-get [[install]] [[hwinfo]]
| |
| − | Then call hwinfo:
| |
| − | hwinfo --usb
| |

| |
| − | Now you should be able to see the video device:
| |
| − | [[ls]] /dev/video*
| |
| − | /dev/video0
| |
| − | You can now test your webcam using the software cheese:
| |
| − | sudo apt-get install cheese
| |
| − | cheese

| − | = Other webcams =
| |
| − | If you have another webcam, try the above nevertheless. If it does not work, exchange the driver gspca against uvcvideo:
| |
| − | yast -i uvcvideo_kmp_default
| |
| − | modprobe uvcvideo
| |
| − | and start gqcam again.
