Whatever the driver is for the webcam, you need to query the driver and see if you can tell it to use /dev/video1.
For instance I have a Logitech QuickCam Express and the driver is mod_quickcam so I enter this:
Code:
# modinfo mod_quickcam
filename: /lib/modules/2.4.21/kernel/drivers/usb/mod_quickcam.o
description: "Logitech Quickcam Express Webcam driver"
author: "see README"
license: "GPL"
parm: debug int, description "Sets the debug output (1,2,4,8,16,32)"
parm: interpolation int, description "Sets the interpolation mode (0-1)"
parm: mode int, description "Sets the speed (0-1)"
parm: keepexposure int, description "Keep gain settings across one open to another (0-1)"
parm: tobgr int, description "Automatic RGB -> BGR conversion"
parm: rgain int, description "Initial value of red gain (0-255)"
parm: bgain int, description "Initial value of blue gain (0-255)"
parm: ggain int, description "Initial value of green gains (0-255)"
parm: bright int, description "Initial value for brightness (0-65535)"
parm: video_nr int, description "Set videodevice number (/dev/videoX)"
So I hi-lighted the parameter I need to pass to the driver i.e. video_nr 1. Now I just edit /etc/modules.conf and pass the parameter to the mod_quickcam driver like thus:
alias camera mod_quickcam video_nr 1
To verify it worked I check in /proc/video/dev
Code:
# cat video0
name : BT878(Hauppauge (bt878))
type : VID_TYPE_CAPTURE|VID_TYPE_TUNER|VID_TYPE_TELETEXT|VID_TYPE_OVERLAY
hardware : 0x1
[dev]# cat video1
name : Logitech Quickcam Express USB
type : VID_TYPE_CAPTURE
hardware : 0xcf1aa310
