Hi Kids!

   Time for a new adventure. I would like to have a working
firewire camera input for manipulation in Gem on a linux
box that is sitting here purring at me. The cam works
fine with Kino and dvgrab, so the linux-firewire connection
is all well.

But I am having no luck with pix_video or pdp_v4l. The main problem
seems to be that (apparently) recently the naming conventions
in debian and possibly linux in general were changed. So there is
no more /dev/video0 for the v4l mode, and for pix_video trying to
work directly with ieee1394, I get complaints that /dev/ieee1394/dv/ 
host/PAL/in
"Is a directory".

Has anyone had more luck? Do I need to going from stable to testing in
some parts of debian? Do I need to use some special somethings?
Hi
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 directory.

%vi /etc/udev/rules.d/50-udev.rules
# IEEE1394 (firewire) devices (must be before raw devices below)
KERNEL=="raw1394", NAME="%k" KERNEL=="dv1394", NAME="dv1394/%k" KERNEL=="video1394*", NAME="video1394/%n"

I havent tested it yet, since i havent any DV cam before hand at the moment.

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
