Kay? Added: KERNEL=="video0", SYMLINK+="video" KERNEL=="radi0", SYMLINK+="radio" vbi -> vbi0 is missing, scantv uses that. Added and submitted. Thanks! This is not just a matter of missing symlinks. The /dev/device0 and 1 and 2 and 3 are missing for video, radio, vbi, vtx, and bttv. This may be the case in all versions. How do I create them that they stay? Put them as real device-nodes with the correct permissions (like they should show up in /dev) in /lib/udev/devices/. They get copied over at every bootup. As root I ran this script.

#!/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
}
#seehttp://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

Of course they only stay there till a reboot. There is NO /lib/udev directory. There is a /dev/.udevdb folder with no class files for the video, radio, etc.

has a lot of details on what I've tried and learned so far.
Oops, sorry, this is 10.0, which I lost the focus. There should be a /etc/udev/static_devices.txt file, where you can add these nodes. This is completely replaced by /lib/udev/devices on 10.1 and almost all other distros today. Please add the needed entries to /etc/udev/static_devices.txt, so that they will be created with every reboot. If you update to 10.1 some day, these nodes belong into /lib/udev/devices/ (as long as the kernel does not get fixed to create the nodes). Closing the bug. |
9.3 has /dev/{video,vbi,radio} symlinks pointing to video0, vbi0, radio0. There are currently udev rules missing to create them. At least the console 'radio' program uses /dev/radio
