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

Hi Dominik,

my bet is that camera1394 pkg does not know how to correctly interpret
the stream from Videre cameras.
Since there was a question on how to get it going with this particular
camera not so long ago, could you please check and try it first:

Shall it not work please report back.

cheers, D.
