I am doing a project about Mobile Robot Teleoperation which uses OpenCV for Computer Vision, but I always get error: libdc1394 error: Failed to initialize libdc1394
The reason is: There is no file /dev/raw1394 since the raw1394 driver is not loaded. So you need to insert that driver:
$ sudo modprobe raw1394
Check your permission access to that dev file:
$ ls -la /dev/raw1394
