Default Connecting a video camera

Hi debian gurus,

I'm trying to figure out if I can download the video from a video camera
onto my linux box. It's a Sony DCR-H52, tape-based, and firewire only.


When I plug it in, I see the following in the log files:

kernel: [89405.861315]: ieee1394: Node added: ID:BUS[0-00:1023]
GUID[0800460103dcd08d]

kernel: [89405.861846]: ieee1394: Node changed: 0-00:1023 -> 0-01:1023
kernel: [89406.985364]: ieee1394: raw1394: /dev/raw1394 device initialized

But neither kino nor dvgrab seem to recognize that a camera is connected.

I'm new to firewire and to video cameras under linux, so I'm stumped.
Anyone else out there have any ideas?


Thanks for your help,

Michael

I used to do this as well, at some point of time there was a 13894
driver in the kernal that allowed you access to your video camera, at
some point 2.6.26 I think this module was removed - declared a security
problem - afaik there hasn't been an alternative method introduced....

you can build your own kernal and compile it in and then dvgrab should
work again!

Have you tried running these apps as root? If that works, it would
indicate a permissions problem. Perhaps your user is not in the
appropriate group. (Check the owner/group/permissions of /dev/raw1394)

I use dvgrab to capture real time video data, will also work if you
just play back a pre-recorded tape on the camera too, but I need to
be root for this, so as Rob said, its probably a permissions issue
on the /dev/raw1394 if you are running as another user.

$ apt-cache search dvgrab
dvgrab - grab digital video data via IEEE1394 and USB linkssearch

Cheers, Tim

Hi,

I think (somebody beats me with a stick if I'm wrong) the two firewire
stacks are currently built in the Debian kernel.

So you could try to unload the current firewire driver, and load the
alternate one, and see how it goes.

To see which modules are available in you kernel :

modprobe -l | grep firewire

To see what is loaded :

lsmod | grep firewire

So if one, or both are loaded, use "modprobe -r module" to unload, and
try to reload one at a time.

You can run

watch "tail /var/log/kern.log"

in a console while plugging the camera to see which driver is loaded
automatically.

Of course some cameras are just not Linux friendly, and then you are
stranded... In such a case you would have to go with an alternate method
to capture the video stream (acquisition card through "s-video" port or
such).

Have fun.

No, that issue was corrected a long time ago. For me, with a current
squeeze, it just works.


As suggested elsewhere in the list, permissions are the most likely
cause of this behaviour. If this doesn't work, please send a lsmod
output with the relevant 1394 and firewire greps. Then I can compare
that with my output and try to find a difference.

Run lsmod. It should show sbp2, ohci1394, and ieee1394 (on Lenny).

Urg. Consider one of these instead:

tail -f /var/log/kern.log
less +F /var/log/kern.log # Ctrl/C to pause; F to resume
