Re: [GnomeMeeting-list] Cannot use FireWire cam with gnomemeeting

[Damien Sandras <dsandras seconix com>]

You have to apply the following patch (contributed by 2 users). It is
not tested so you are a good way to test it.
It will not be included in the next release because it is too late too
integrate it before the release.

Please report problems or success :)
