apparently this is a problem related to the new behavior of udev under
Debian. I wouldn't recommand to downgrad udev though. I read the
following on videolan's website:
if you have a distribution that uses udev, then you must add/change the
following line to the file 50-udev.rules in your /etc/udev/rules.d
# IEEE1394 (firewire) devices (must be before raw devices below)
KERNEL=="raw1394", NAME="%k" KERNEL=="dv1394", NAME="dv1394/%k"
I havent tested it yet, since i havent any DV cam before hand at the
The workaround i used at the time is the following:
first check that you belong to the right groups : disk and video by
issuing the command groups
If not, then
$ sudo adduser username disk
$ sudo adduser username video
then run the attached bash script as a superuser after each restart:
$ sudo bash ./dv.sh
you might have to chmod +x the shell script
Start Pd/Gem, pix_video should work as expected if feeded with the
pathname given in the shell script
(I cant remember well this part, i'm sorry i'm only sending a
translation of my blog notes, i dont have access to the original machine
and Pd program this week (public holiday).)
The shell was adapted from an article about Ubuntu Edgy and DV cams
