Description Jukka Ketelaars 2006-02-25 18:06:04 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.1) Gecko/20060223 Fedora/1.5.0.1-5 Firefox/1.5.0.1

Description of problem:
Ekiga is unable to access a webcam at /dev/video0 due to the permission being 660 and group 'root'.

Version-Release number of selected component (if applicable):
udev-084-6

How reproducible:
Always

Steps to Reproduce:
1. connect webcam 
2. webcam shows up as /dev/video0
3. start ekiga
4. try to select webcam in first-run dialog or at Edit->Prefernces->Devices->Video devices
  

Actual Results:  Device does not show up.

Expected Results:  Device should have been selectable.

Additional info:

The problem is that /dev/video0 is created as root:root 660, so normal users can not access it. I fixed it by changing (in /etc/udev/rules.d/50-udev.rules) the video line from:
  KERNEL=="video*",               MODE="0660"
to:
  KERNEL=="video*",               MODE="0666"

This probably is not an ideal solution on anything other than a single user system.
Comment 1 Harald Hoyer 2006-02-27 13:00:52 UTC 
/etc/security/console.perms.d/50-default.perms should contain:
<v4l>=/dev/video* /dev/radio* /dev/winradio* /dev/vtx* /dev/vbi* \
      /dev/video/*

And as long, as you are a console user (first console login), you should own
this device.
