Capturing video over Firewire
Disclaimer
This section on using IEEE3945 is not written by a hardware expert, it probably contains mistakes, if you know something is wrong or missing please help improve this page for the next person by correcting it. DuncanLithgow
Hardware
Firewire is the common name for the standard known as IEEE1394. Many digital camcorders and many computers have a built-in Firewire ports. You can read more general notes about Firewire and see what the ports and cables look like in the Wikipedia entry: http://en.wikipedia.org/wiki/IEEE_1394 . If your computer doesn't have a Firewire port you can add a PCI expansion card. You should note that if you plan on buying an expansion card you must be sure that your system BIOS will support it.
Software
Most Linux distributions, including Ubuntu, do not support file transfer via Firewire by default so you'll need some extra software. This page looks at using the dvgrab application which is part of the Kino Video Editor. You can install a stable version of Kino in Ubuntu via 'Applications > Add/Remove...'. If none of the methods on this page work try installing the latest version from the Kino Website. The dvgrab package uses a device file (also known as a node) in Ubuntu to acts as an interface from your camera to Kino over the Firewire port. When you connect your camera and turn it on, the udev package should create one or more of the device files needed. If Ubuntu doesn't create a device node you will need to give it a kick with
sudo modprobe dv1394
Depending on which version of Ubuntu you are running the device node can be any one of:
- /dev/dv1394-0 (misnamed, same functionality as /dev/dv1394/0 )
- /dev/dv1394/0 (gives access to Firewire for video capture but not to the camera's controls)
- /dev/raw1394 (gives raw access to Firewire and allows access to your cameras controls, but poses a security risk)
This guide assumes you want to use dv1394/0 as this is the preferred method. A discussion of why 'dv1394/0' is prefered can be seen in Launchpad Bug# 6290 Start Kino and open the 'Capture' tab. Kino will attempt to connect to your firewire port and detect any device there. Kino tries /dev/raw1394 by default, which will fail. You will see the error:
| WARNING: raw1394 kernel module not loaded or failure to read/write /dev/raw1394! |
Which is not a bug, it's a security feature which you can read about this email from Scott James Remnant. If these tips do not work please file a bug in launchpad against Kino.
Ubuntu 6.06 LTS (Dapper Drake)
Kino 0.9 can be installed from source in Ubuntu 6.06. Under 'Edit > Preferences > Capture > dv1394 Device' change the value to '/dev/dv1394-0'.
Ubuntu 6.10 (Edgy Eft)
Kino 0.9 can be installed from the main repository. Make sure you install kinoplus, you can search for kinoplus in 'System > Administration > Synaptic Package Manager'. Once Kino starts under 'Edit > Preferences > Capture > dv1394 Device' change the value to '/dev/dv1394/0'.
Ubuntu 7.10 (Gutsy Gibbon)
To access your video camera you will need to run Kino (version 1.1.0) as root, type the following into a terminal: gksudo kino
Other methods
Method 1. 'dv1394-0'
If you have a file called '/dev/dv1394-0' in Kino go to 'Edit > Preferences' and select the 'IEEE 1394' tab. Any detected cameras should be listed under 'AV/C Device', but it may still work if your camera is not seen at first. Make sure the tape is ready where you want to start capture. On the 'Capture' tab press play on your camera then 'Capture' button.
Method 2. 'raw1396'
If you have physical control of your computer and there is no risk of the Firewire port being used to access your machine then this method may be suitable for you. But it is still a security risk. This method makes a new group called firewire with control of the raw1394 device file, and your user a member of that group.
- Open 'System > Administration > Users and Groups'. Add a new group and call it firewire
- Open the firewire group and add your user name to this group.
- Start Nautilus as root by opening a terminal and typing
gksudo nautilus
- Find the file '/dev/raw1396' and from the right click context menu select 'Properties'
- Under the 'Permissions' tab make firewire the group of this file.
Method 3. 'video1394'
Some versions of Ubuntu have a video1394 group. Use the approach in method 2 to add yourself to the video1394 group.
Method 4. 'as root'
If the methods above haven't helped, try also running kino as root, that might get around a few things.
gksudo kino
Method 5. 'GROUP=video'
In order to enable dv capturing with Feisty you just have to modify the file "/etc/udev/rules.d/40-permissions.rules" and change KERNEL==”raw1394″, GROUP=”disk” to KERNEL==”raw1394″, GROUP=”video” Then just add "ieee1394" (without quotation marks) to "/etc/modules"
