Red Hat Bugzilla – Bug 191670
Device node for digital video camera not owned by console owner
Last modified: 2013-03-05 22:45:33 EST
Description of problem:
I have a Canon ZR100 digital video camera with a IEEE-1394 interface. When I
plug in the camera, the associated device node is owned by root. As a result,
normal users can not access the camera using dvgrab.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log in as a normal user.
2. Connect the video camera using IEEE-1394
3. Try to capture video using dvgrab
raw1394 - failed to get handle: Permission denied.
When a user logs in and obtains console ownership using pam_console, the
ownership of /dev/raw1394 should be set to that user.
The gphoto2 package installs a HAL policy that runs a script
(/usr/libexec/gphoto-set-procperm) when a digital camera is plugged in to the
system's USB bus. The same should be done for digital video cameras.
Is there a package that handles digital video camera access (like gphoto handles
digital cameras)? That would be the correct place to put associated fdi files
I don't think we have a definitive package. The dvgrab package is an option,
but it is not the only way to grab video from a camera. I think even gstreamer
has a IEEE-1394 src. Right now I don't believe there is one single package that
must be installed if one is to interact with video cameras using Fedora.
Perhaps we should create a package like desktop-printing? This could be a
lightweight package that is required by all video camera-related packages.
can you attach the output of `lshal` with the camera plugged in. Thanks.

John, should this be assigned to David Zeuthen? I understand you and he have
traded places at Red Hat.
Fedora apologizes that these issues have not been resolved yet. We're
sorry it's taken so long for your bug to be properly triaged and acted
on. We appreciate the time you took to report this issue and want to

If you're currently running a version of Fedora Core between 1 and 6,
please note that Fedora no longer maintains these releases. We strongly
encourage you to upgrade to a current Fedora release. In order to
refocus our efforts as a project we are flagging all of the open bugs
for releases which are no longer maintained and closing them.
If this bug is still open against Fedora Core 1 through 6, thirty days
from now, it will be closed 'WONTFIX'. If you can reporduce this bug in
the latest Fedora version, please change to the respective version. If
you are unable to do this, please add a comment to this bug requesting
Thanks for your help, and we apologize again that we haven't handled
these issues to this point.
The process we are following is outlined here:
We will be following the process here:

Is this superceded by bug #441073 - user firewire permissions and dvgrab in F9?
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Superceded by bug #441073 - user firewire permissions and dvgrab in F9.
Can the owner close this as a dup?
