Package: kdetv
Version: 0.8.9-1
Severity: important
Tags: squeeze patch
Kdetv has not found any video device at my system.
It assumes that if the directory /dev/v4l exists the video
device is also in this directory.
$ ll /dev/video0
crw-rw----+ 1 root video 81, 0 22. Mai 01:40 /dev/video0
$ ll /dev/v4l/
insgesamt 0
drwxr-xr-x 2 root root 80 21. Mai 19:52 by-path
$ ll -d /dev/v4l/
drwxr-xr-x 3 root root 60 21. Mai 19:52 /dev/v4l/
The attached patch does only check all devices:
/dev/video
/dev/video[0-9]
/dev/v4l/video[0-9]
