After poking around I came up with the following workaround. It creates some symlinks in the /dev folder that match where OpenCV now expects the raw1394 device to be:
sudo mkdir /dev/video1394
sudo ln -s /dev/video1394-0 /dev/video1394/0
sudo chmod 777 -R /dev/raw1394 \
It appears OpenCV or libdc1394-13(-dev) is trying to open the wrong video block device file. It this continues to be an issue, this linking could be set up automatically in 'udev'.
Let me know if this helps you out!
