Having trouble with my digital video camera and my Linux Red Hat workstation.
When I attache my Canon ZR50 to my laptop via firewire the camera shows me [DV IN] (which is normal as far as I remember) but the device does not show up on my workstation.
lspci shows the firewire port as active but I never get an entry in /dev/fw* ... so I am not sure if my laptop has an issue or my camera.
I have not used it in a while and the last time I captured video from it was 2-3 years back when I still used Windows (different PC from what I have now)

Any idea where I can start digging to get to the bottom of this? I see no error in /var/log/messages ... a bit of a mystery.

Details: Lenovo T61p
OS: Red Hat 2.6.18-194.11.1.el5PAE

Post the output of the lsmod command. This will tell us what if any of the firewire modules are being loaded.
You need:
raw1394
dv1394

Thanks, I'll try that this evening when I get back home to my laptop - appreciate the hint!

looks like it is not loading those modules - here the output below. I'll see if google helps me find a solution, any hint how to prceed from here woudl be appreciated!

You can load them via the modprobe command. i.e.
modprobe ohci1394
modprobe raw1394
modprobe dv1394
modprove video1394

If all goes well you will not see any messages. The two applications that I have used in the past are dvgrab and kino to download video from the camera. If all that works you can add the modules to the /etc/modprobe.conf file.

I don't seem to have those modules. I checked and have raw1394.i386 inswtalled so I uninstalled it and re-installed .. no change:

# modprobe ohci1394
FATAL: Module ohci1394 not found.
# modprobe raw1394
FATAL: Module raw1394 not found.
# modprobe dv1394
FATAL: Module dv1394 not found.
# modprobe video1394
FATAL: Module video1394 not found.

I looked in the /lib/modules/2.6.18-194.11.1.el5PAE/kernel/drivers nd could not find any of the modules, just the firewire folder that contains the firewire-core.ko firewire-ohci.ko firewire-sbp2.ko modules.

I also looked in the left over kernel folders /2.6.18-194.3.1.el5PAE and /2.6.18-194.8.1.el5PAE and there was nothing there either. BTW - I never know .. can I ge rid of those old kernel folders or do I need to leave them hanging around? Unrelated to my current prpblem but I want to tidy up is necessary.

I found a firewire blacklist int eh system and commented the firewire out and restarted. I am kind assuming I might have to re-compile the kernel? Not sure, anybody who can point me in the right direction?

Thanks!

Interesting. The new firewire stack did not get released until 2.6.31 so I assumed your kernel was still using the old stuff. firewire-core, firewire-ochi and firewire-sbp2 are the new modules.

aha - so that means the modules I need to start with modprobe would then be these three firewire-core.ko firewire-ohci.ko firewire-sbp2.ko modules? I'll give that a wiz tonight at home and see if dvgrab works ... I should have though of trying that last night but it was LATE last night and I was burnt.

Thanks!!

SUCCESS!

started dvgrab ..... and am now currently capturing video on my machine

THANKS!

I tried the above and I can see the modules running. I am able to read the video from my flea2 camera connected through firewire , using Coriander. However, when I use this simple code from opencv, the camera is not being detected.

#include "/home/iiith/opencv-2.4.9/include/opencv/cv.h"
#include "/home/iiith/opencv-2.4.9/include/opencv/highgui.h"
#include "cxcore.h"
#include <iostream>

using namespace cv;
using namespace std;

int main(int,char**)
{
VideoCapture cap(0);
if(!cap.isOpened())
cout<<"Camera not detected"<<endl;
}

The output is always that the camera is not detected. Considering the value of the variable can be wrong, I even tried displaying the image from the frame and I got an error saying empty image and thus an error thrown by the Mat funtion. Can you please help me and tell me how to make it work in Opencv? Thanks in advance.
