Hello,  
As you can see in this video:

My app crashes when I activate the webcam

This is an app I have created following the UE + OpenCV tutorial:

Hi,  
I feel your pain. I have managed to use the webcam for a specific task.  
1.read a frame from the webcam. convert it to greyscale  
2.save the frame on disk

I still have to make the webcam stream visible to a texture inside UE.  
Once that is done I will post a how-to and up a git repo so you cna study from it.

Cheers,
