Irrlicht Engine

Firstly, thank you. I prefer to use Dev-C++. I located the source of my problem, but i am no idea. If I use irrlicht 1.4.1, it's good, but, if I use irrlicht 1.6, it's bad xD. The webcam is not update. T.T
One idea ?

I'm using irrlicht 1.6, OpenGL. I haven't made a change the irrAR code.
I see webcam images change when the program detect a pattern, else, she doesn't change.

PS : i am making a video for that you see

I managed to compile with MSVC. Everything works, but, when the webcam sees the pattern, she modifies the background, but when she doesn't see, she doesn't modifies.
One idea ?

I can not with MSVC, so can you explain me what can i do for the methods others, please because I don't know to do

I don't use MSVC, I use Dev-C++, and use g++.
I'm sorry if I make faults, because I'm french :p, but what can i do for my problems ? i would like to use this library^^
