Fixed this one by checking if buffer is null or not... my webcam which i use for testing needs a little bit longer for initialization.
But when calling arDetectMarker, i need to pass the image data so that ARToolkit can process ist. For that image->editData() is used, So the call arDetectMarker(image->editData(), thresh, &markers, &numberOfMarkers) is always crashing. (editData is used because arDetectMarker doesn't take a const UInt8*). this is always crashing. I suspect some multithreading issues, could someone help me on that please ?

So now for the next part -> using it with OpenSG 2.0 J Already converted it, but when calling grabImage , dfg->getFrame() just returns a bad buffer. Might that be a problem because of Win7 (and none existing DX 9 ?). Cheers, Georg
