Summary0000318: "Fix" button for allowing user access to capture device /dev/raw1394 or whatever?
DescriptionOn my system (Debian Lenny) and on previous Kubuntu setups, when I want to capture footage from within Kino I needed to either run Kino as root, or run '$ sudo chmod 666 /dev/raw1394' to get read access to that device. Also adding a user to the group that owns that device may resolve the problem, or to the 'video' group.

It would be nice to have a button that somehow will fix this so that the user has read access from this device when attempting to capture in KDEnlive.

However the fix may be difficult to implement across distros and may have security concerns (there is a new firewire stack being built to try to avoid these issues but I don't think it is used much yet; it is named Juju and more info here [^] )
Additional InformationThis may be distro specific or may be bad *nix practice, so I am just throwing the idea out there to help those that may not understand why they cannot capture; I am not claiming this is a great idea but it may be useful. Dan D would know much more about 1394 in general I am sure.

Debian Lenny (my system)
/dev/raw1394 - owned by root:disk; being in group 'video' doesn't fix

Mandriva 2009 (goibhniu's system, from #kdenlive)
/dev/raw1394 - owned by root:root but being in group 'video' fixes this

I noticed that the permissions change after connecting the camera:
crw-rw---- 1 root video

It sounds like debian based distros have it in the "disk" group instead of "video": [^]

I have been dealing with this for years. The only real resolution is the new FireWire stack and the proper udev changes to facilitate it.

So, what should we do with this feature request? Make it into something like "Support Juju configuration through Kdenlive GUI" - when it is done? Postpone it to 1.0.0?

Maybe you could offer the option to launch dvgrab with kdesu?

There is not really anything to add GUI wise to support the new FireWire stack. udev needs to lookup the type of device when it is plugged in and set the permission on a /dev/fwX file. It should all be automatic. The fact that raw1394 only has one file on ieee1394 prevented this.

Acknowledging for 0.7.1 as a feature wish for "run dvgrab with kdesu" if users check a box or similar.

Adding "kdesu " before the dvgrab command should be fairly trivial (correct me if I'm wrong), but would this be supported on all systems (such as gnome environments) ?
