Agreed -- I remember how hard it was to find the right documentation
when I was setting up my video capture card.
On my system, /dev/video is a symlink to /dev/video0, which is a
character special device with major 81 and minor 0. If you feel
comfortable with it, you could create it manually, but there should
be a script lying around somewhere that would do it for you.
Hey, found it... why don't I just include it for you?
MAKEDEV.v4l:
------------
#!/bin/bash
function makedev () {
for dev in 0 1 2 3; do
echo "/dev/$1$dev: char 81 $[ $2 + $dev ]"
rm -f /dev/$1$dev
mknod /dev/$1$dev c 81 $[ $2 + $dev ]
chmod 666 /dev/$1$dev
done
# symlink for default device
rm -f /dev/$1
ln -s /dev/${1}0 /dev/$1
}
# see http://roadrunner.swansea.uk.linux.org/v4lapi.shtml
echo "*** new device names ***"
makedev video 0
makedev radio 64
makedev vtx 192
makedev vbi 224
#echo "*** old device names (for compatibility only) ***"
#makedev bttv 0
#makedev bttv-fm 64
#makedev bttv-vbi 224
------------
Knock yourself out!
