 |
|
after successful installing my TV card and Webcam drivers, i found another problem..
If i modprobe TV card, the tv card would @ /dev/video0, meanwhile I modprobe my webcam, the webcam @ /dev/video0 as well.
so i cannot watch tv and use my webcam at same time,
how can i make webcam @ /dev/video1 ?
otherwise, one of them cannot work properly..due to they are both @ /dev/video0
thanks in advance. |

coolone,
They should get ascending device numbers in /dev/v4l/
Maybe its udev messing up the symlink ?
With the TV Card and Webcam both connected, what do you have in /dev/v4l/ ?

coolone,
Thats your webcam and your TV card.
Now look at /dev/video*. Do you also have two symbolic links like this | Code: | $ ls -l /dev/video*
lrwxrwxrwx 1 root root 10 Jan 2 11:31 /dev/video0 -> v4l/video0
lrwxrwxrwx 1 root root 10 Jan 2 11:31 /dev/video1 -> v4l/video1 |
If so, all is well except that video0 will always be assigned to the first device detected. To fix the names to devices and/or chaneg them to say
/dev/tv and /dev/webcam you need to write some udev rules following [urk=http://reactivated.net/writing_udev_rules.html]this guide[/url]
