/dev question

[Jachete]

Hello,

i am very new to the linux world, but would like to use my AMD64 powered linux (Ubuntu) box to edit video.

Both Cinelerra and Kino require /dev/raw1394 and /dev/dv1394, but these are not present on my system. 

Can anyone tell me how to make these present at boot time, so that I don't have to fight so hard any more?

Thanks,
JH

JH,

I had the same problem too and I think it's due to the 1394 driver not
being udev aware.  As a quick fix I just added these lines
to /etc/rc.local:

[ ! -e /dev/raw1394 ] && \
    /bin/mknod -m 0660 /dev/raw1394 c 171 0 &>/dev/null; \
    /bin/chown root.users /dev/raw1394 &>/dev/null

You could do the same for dv1394, but I don't know what the major/minor
numbers are for that device node.

Hope this helps.

The kernel driver does not create sysfs entries for that device and
therefore udev will do nothing here. This was already implemented for
the 1394 drivers the last time I looked in their CVS, but I don't know
if it is already merged into the mainline kernel. 

For now just do:
  mknod /dev/raw1394 c 171 0
  mknod /dev/dv1394 c 171 32

Good luck,
