Hi folks,
I actually just had the same problem. What I found out is that the firewire
camera works fine with libdc1394 that is provided with Ubuntu (or latest
version 2.1.2 from sourceforge) but not with lidc1394 package included with
ROS. That is, running exactly the same code works fine libdc from Ubuntu's
repos, but not with the version of libdc included in ROS.
I've modified the Makefile of libdc1394 package to download a tarball from
sourceforge and it seems to work fine. I was able to connect to my stereo
cam and get images. Dominik, could you try that Makefile and let me know if
that fixes you troubles? Also make sure you have rw access to /dev/raw1394.
Every time you plug in the camera this file will be owned by root, unless
you have some rules setup to change the group and/or permissions.
Thanks,
Anton
