channel# is not valid

Hi Marc,

It 's seems to me that you were not able to read the following file:
Data/camera_para.dat

Make sure your executable can read that file, which in the ARToolKit 
distribution reside in bin/Data

Hope this help
Alex

Subject:	channel# is not valid
Hi all, I'm a newbie here, so sorry if the question is stupid... When using ARToolkit with a standard USB camera, i got the following error msg : arVideoOpen: channel# is not valid. I've changed the channel manually to 0, but then got the error Image size (x,y) = (640,480) Camera parameter load error !! It's probably a stupid parameter error, but i don't have much time to spend on it ... Could someone help me and give me a direction to search ? Thanks. Marc
