Black screen from webcam/image source in OpenCV, including in girlpowers/help files. (33.7)

Hi all,

I’m keen to play with the awesome looking OpenCV pack, but I’m having a strange issue.

When I try to stream my logitech hd pro c920 webcam via the videoin node, everything seems to be recognised, but I get a black screen in the renderer.

I tried loading some girlpowers to see if it was just that one patch, but it seems to be a consistent issue.

VVVV recognises the webcam, which lights up in response, and I can even see it adjusting the lighting and focus settings in the logitech settings program when I move it around the room, but all I see in the renderer is a black screen.

I get picture everywhere that isn’t vvvv.

Any thoughts?
