Hi,
I'm trying to install ARtoolkit on Ubuntu 8.10 "Intrepid" (Linux
2.6.27-11-generic on x86_64).
The uvcvideo driver implements the Video4Linux 2 (V4L2) API. V4L1 is not
supported.
I applied a patch to add support for Video 4 Linux 2 devices into the
artoolkit based on the artk 2.72.1 tarball.
ubu...@ubuntu:/tmp$ v4l-info
### v4l2 device info [/dev/video0] ###
general info
VIDIOC_QUERYCAP
driver : "uvcvideo"
card : "Philips SPC 1330NC"
bus_info : "0000:00:1d.7"
version : 0.1.0
capabilities : 0x4000001 [VIDEO_CAPTURE,STREAMING]
I succeeded to compile but I get a black window screen :
/ubu...@ubuntu:/usr/local/ARToolKit/bin$ ./simpleLite

return 1;

return 1;
} else {
/In dmesg, I get :

How can I fix it ?
Thank you very much for your help.
