This is "how to" change positions of video* devices regardless hardware
and kernel's default settings;
Query:
udevinfo -a -p $(udevinfo -q path -n /dev/video0)
or
udevinfo -a -p /class/video4linux/video0
Udev rules:
/etc/udev/rules.d/10-local.rules:
# TV card initialization&relocation - video
SUBSYSTEM=="video4linux", ACTION=="add", DRIVERS=="?*",
ATTR{name}=="BT878 video (Hauppauge (bt878))", KERNELS=="0000:02:03.0",
KERNEL=="video*", NAME="video0", SYMLINK+="Bt878.video"
SUBSYSTEM=="video4linux", ACTION=="add", DRIVERS=="?*",
ATTR{name}=="ivtv0 encoder MPG", KERNELS=="0000:02:01.0",
KERNEL=="video*", NAME="video1", SYMLINK+="iTVC16.enc"
# TV card initialization&relocation - vbi
SUBSYSTEM=="video4linux", ACTION=="add", DRIVERS=="?*",
ATTR{name}=="BT878 vbi (Hauppauge (bt878))", KERNELS=="0000:02:03.0",
KERNEL=="vbi*", NAME="vbi0", SYMLINK+="Bt878.ttx"
SUBSYSTEM=="video4linux", ACTION=="add", DRIVERS=="?*",
ATTR{name}=="ivtv0 encoder VBI", KERNELS=="0000:02:01.0",
KERNEL=="vbi*", NAME="vbi1", SYMLINK+="iTVC16.ttxe"
