Hi all,

Has anyone installed the ARToolKit 2.70.1 version in Linux system? I use two 
Fire-i IEEE 1394 video cameras. After I installed it, the simpleTest example 
works well. But the twoView example doesn't work.

Following is the running result:

Auto-detecting firewire camera because card and node is not specified
1394 card 0 node 0 is a [Unibrain - Fire-i 1.2] --> auto detected
1394 card 0 node 1 is a [Unibrain - Fire-i 1.2] --> not used
1394 card 0 node 2 is not a camera [INVALID]
Using the firewire camera on card 0 and node 0
unable to set camera trigger mode (ignored)
demoARSetupCameras(): Camera 1 image size (x,y) = (640,480)
*** Camera 1 parameter ***
--------------------------------------

(dc1394_capture.c) Unable to set video mode 66!
unable to setup camera-
check if you did 'insmod video1394' or,
check line 492 of video.c to make sure
that the video mode,framerate and format are
supported by your camera
Quitting...




And how to set the camera configuration in the following part for IEEE1394 
video camera in Linux system?

char *vconfs[] = {		
#if defined(_WIN32)
		"showDlg,flipV",
		"showDlg,flipV",
#elif defined(__APPLE__)
		"",
		"",
#else
"-dev=/dev/video0 -channel=0 -palette=YUV420P -width=320 -height=240",
"-dev=/dev/video3 -channel=0 -palette=YUV420P -width=320 -height=240",
#endif
	};


Any help is appreciated.

Thanks.
Regards,
Jiang

This excerpt from the source should answer your questions and help you=20=

build valid vconf lines:

int ar2VideoDispOption( void )
{
printf("ARVideo may be configured using one or more of the following=20
options,\n");
printf("separated by a space:\n\n");
printf(" -node=3DN\n");
printf("    specifies detected node ID of a FireWire camera (-1:=20
Any).\n");
printf(" -card=3DN\n");
printf("    specifies the FireWire adaptor id number (-1: Any).\n");
printf(" -mode=3D[320x240_YUV422|640x480_RGB|640x480_YUV411]\n");
printf("    specifies input image format.\n");
printf(" -rate=3DN\n");
printf("    specifies desired framerate of a FireWire camera. \n");
printf("    (1.875, 3.75, 7.5, 15, 30, 60)\n");
printf(" -[name]=3DN  where name is brightness, iris, shutter, gain,=20
saturation, gamma, sharpness\n");
printf("    (value must be a legal value for this parameter - use=20
coriander to find what they are\n");
