Perfectly good English. And it did tell you the problem: access rights. Look at the driver - it might be /dev/video or /dev/video0 - and check the permissions. It may be installed, but only root has rw privileges. If that's the case, one option would be to make it owned by root, but group motion, and add yourself to that group. mark _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos |

Hello Johan. I've done some looking into this before, and if you checkout my Linux Compatible Webcams Guide you will see that if you use a Logitec c210 which is a UVC camera - and the driver for UVC devices is already built into the newer Linux kernel. http://forums.fedoraforum.org/showthread.php?t=240812 "However, the current Linux 2.6.26 kernel and newer includes the Linux UVC driver natively. So you will not need to download and compile any driver module source if you purchase a UVC compatible webcam. It should be Plug-n-Play like any other USB device" It looks Like RH may have backported the UVC drivers into the kernel, as I can use my Logitec webcam OK under Skype :) [root@karsites ~]# rpm -qv kernel kernel-2.6.18-238.5.1.el5 kernel-2.6.18-238.9.1.el5 kernel-2.6.18-194.32.1.el5 kernel-2.6.18-238.12.1.el5 kernel-2.6.18-238.19.1.el5 [root@karsites ~]# lsusb Bus 001 Device 006: ID 046d:0802 Logitech, Inc.

hello Mark and Keith,
I also think a have the driver, because of what dmesg shows. mark could be right, I had a similar issue with a firewire camera, Kino and /dev/raw1394. So a did this : -bash-4.1# groupadd motion -bash-4.1# chgrp motion video0 -bash-4.1# usermod -G motion james -bash-4.1# id james uid=500(james) gid=500(james) groepen=500(james),503(motion) -bash-4.1# ls -la video0 crw-rw----+ 1 root motion 81, 0 sep 21 21:28 video0 -bash-4.1# hope this is right. But still same error message, even after reboot ( didn't want to but battery went dead ) So still no video... greetings, James Op 21-09-11 20:54, m.roth@5-cent.us schreef: > Johan Vermeulen wrote: >> when first installing CentOs some 6 months ago, I noticed this strange >> thing called Ekiga. > <snip> >> # yum search V4L2 > That's video4linux, btw. > >> with epel testing enabled. >> >> #dmesg | tail -n15 shows : > <snip> >> still in Ekiga i get error message ( translated from Dutch) : >> >> an error occurred with video device UVC Camera (046d:0819) >> an error occurred when opening the device >> blahblahbla >> check access rights or driver. >> >> under System - Preferences I can't find anything configurable ( is that >> even English ?) > Perfectly good English.

I kind of did the same for /dev/v4l
-bash-4.1# ls -la v4l/ totaal 0 drwxrwx---. 4 root motion 80 sep 21 21:28 . drwxrwxrwx. 21 root root 3820 sep 21 21:28 .. drwxrwx---. 2 root motion 60 sep 21 21:28 by-id drwxrwx---. 2 root motion 60 sep 21 21:28 by-path -bash-4.1# still no luck. error message persists.

Back when I was handsome I used a webcam. It was a long time ago but I remember one test was to do "cat /dev/video0"... or some other device (if dmesg and /var/log/messages don't say). If you selected the correct device and had the permissions (you could try the command as a regular user or as root), that command would spew out (garbage) characters to the terminal while the cam was moving and seem to pause when the cam wasn't moving and pointed at nothing moving. Ctrl-C or Ctrl-D gave the shell prompt back (as we'd expect). hth, k. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos |
