Thank you. I tried to move to 4.0 and had tbb_debug.dll not found or.... I don't know how to MAKE so need binaries. Are the included in 2.4.5? I'll try to switch. The book I bought was written for 2.2 so I thought it best to begin with that version. Thanks again.

When I comple (opencv 2.2) I get a string of these warnings. Program runs but all camera input images are grey. Could this be why. On of the modules it cant open is vidc32.dll; but the file is there and in the proper folder.

Not using straight c that I know of. Will trim code down and send today. Thanks again.

It returns 1. Also tried capture>>frame, capture.grab & retrieve(frame). All return 1 but still no imshow('name',frame) other than grey. Also retuns zero for width and color!!! Thanks for your help. Maybe I should do straight c++?

I said "as long as it is slower, of course." My system reading at 10 fps with medium hi res 1280. If you need speed, you need fast hardware or reduce you window size etc.

Tried that already. Camera opens and lights up, but returns 0 size and fps.

You can read the frame rate achieved with ' double rate=capture.get(CV_CAP_PROP_FPS); '. Then you can add an internal delay in your capture.read(frame) loop to match the speed you want (as long as it is slower, of course). Hope this helps.

I am using opencv2.2 with windows vista. All I see is a grey image when calling the camera input. Can someone suggest me the best camera input method?

if(!capture.isOpened()) // check if we succeeded
