What is on Linux the major and minor number of the device file for the
cam? on FreeBSD it is:
$ ls -l /dev/video0
crw-rw-rw- 1 root operator 0, 146 19 mar 09:02 /dev/video0
it seems that the algorithm in vidinput_v4l.cxx depends on minor
numbers below 63 in void V4LNames::ReadDeviceDirectory()
see also the CVS comment:
* Revision 1.3 2003/11/25 22:55:13 dsandras
* Added fallback using major and minor numbers for detection of devices
* when /proc/video doesn't exist
(some 2.4 kernels and all 2.6 kernels).
