Kino: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!

I am borrowing a video camera this week for a project and I want to be able to edit video. The first program I decided to install was Kino. It seems pretty full featured so far and I am impressed. I wasn't able to pull down video over the 1394 (FireWire) interface (/dev/raw1394) at first though. I got the error message:

WARNING: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!

This was an easy fix. My problem was the latter. I could not read/write from/to the device. To fix that, open up a command line and do this:

sudo chmod a+rw /dev/raw1394

That will change the file permissions to allow all users read and write access. You can verify all users have read/write access now by doing this:

$ ls -l /dev/raw1394
crw-rw-rw- 1 root disk 171, 0 2008-04-12 19:56 /dev/raw1394


(File permissions explained) The third set of rw needs to be there.

That is hopefully all there is to it for you. It would be nice if the file permissions were automatically changed.

You beautiful person you, this solved my problem! :D I was wondering if I might be able to post my problem in the ubuntu beginner forums and link to your website as part of the solution? I'm not sure if I'll actually create the post but thanks again for the advice.

I'm glad to have helped. That is why I posted this. When I had this problem I didn't find a quick solution. I also thought that the error message was quite unhelpful. Feel free to link to it anywhere you'd like and thanks for reading my blog.

thats cool, worked for me. But you have to do this every time you boot!? can this be changed so Ubuntu remembers the permissions?

Instead of allowing everybody to read/write to that device, you can add yourself to the disk group, logout, login, and you'll be able to use the device without having to worry about the permissions. Just add your username in the corresponding line in the file /etc/group.

You may have to create the group 'disk'. I found no group 'disk' nor 'video' after a fresh install of Ubuntu 8.10, although both groups are referenced in
/etc/udev/rules.d/40-permissions.rules !

For Some reason it keeps resetting after a reboot....

I'd use KUBUNTU 8.04 and try to use KDENLIVE and also get error will capturing via raw1394 DV capture.
I try to follow this blog instruction which I think this just similar instruction.
But, oops!
I've got these:
muslih@Linux-Laptop:~$ sudo chmod 777 /dev/raw1349
chmod: cannot access `/dev/raw1349': No such file or directory
muslih@Linux-Laptop:~$ sudo ls -l /dev/raw1349
ls: cannot access /dev/raw1349: No such file or directory
muslih@Linux-Laptop:~$ sudo chmod a+rw /dev/raw1349
chmod: cannot access `/dev/raw1349': No such file or directory
muslih@Linux-Laptop:~$

Heru: Check your spelling - you used 1349 in the terminal instead of 1394!


Thanks for this post - it solved this problem far more quickly and easily than I expected!

It doesn't work for me because after I type in: "sudo chmod a+rw /dev/raw1394" it comes up with "chmod: cannot access `/dev/raw1394': No such file or directory"

After fighting a war for 4 days, finally i managed to solve this problem in Ubuntu...

The cause: Ubuntu has actually blacklist firewire-ohci
The solution: edit with sudo (admin) rights this file

/etc/modprobe.d/blacklist-firewire.conf

Anything without # means it has been blacklisted.
If you realised that firewire-ohci has been blacklisted, simply add # infront so that i looks as #blacklist firewire-ohci

Save the file, reboot and start Kino with sudo rights.
Click on capture and all should work fine now

Good luck!

Cheers!

As always, there's someone else out there who's already experienced my problem. Thanks for pointing at the permissions issue. Mine now works too. Cheers, Drew-Huddersfield
