v4l-info - dump video4linux(2) device info to stdout
v4l-info [ device ]
v4l-info just prints the v4l(2) device info, i.e. calls lots of ioctls
and dumps the results to stdout. It optionally accepts the device you
want to query. Default is /dev/video0.
Was written to help debug drivers, probably not that useful for end
users ...
