Hi Vishwas,

 

The example you are using, "Grab and Save to AVI," is specific to IMAQ drivers. Your webcam can only function with the IMAQdx drivers, not IMAQ. This document outlines the difference between the two: http://digital.ni.com/public.nsf/allkb/4331B4AA3AE95233862574C200539A2F. In order to get your code working, please take a look at the LabVIEW examples under IMAQdx. It looks like someone has already written IMAQdx code that does what you want in this community example: https://decibel.ni.com/content/docs/DOC-3587.

 

Also, when you select a camera in MAX the camera resource becomes reserved, so if you try to access it in LabVIEW, you'll get an error. Once you have migrated to the IMAQdx drivers, make sure that MAX is closed, or the camera is not selected before you run the LabVIEW VI.

Actually i am facing problem in interfacing my inspiron1545 dell integrated webcam with IMAQdx, I cant see my device in list. But one of my friend told if he is using USB external web cam it is visible in the list. Please guide for the integrated web cam what else i need to use my leaptop web cam. I am using Windows 7 32bit.

Hi,

 

It is likely that your integrated webcam does not run on any of the protocols that is supported by IMAQdx.  Check out this article for which cameras are supported by NI's drivers.

If you don't already see the camera in MAX it may be that the camera is not supported.  I can not say for sure so you will need to check if the camera follows one of the protocols supported by the IMAQdx driver.  In specific, I would check if the camera is DirectShow compatible.

Hi,

 

I won't be able to check for you since we do not have the camera model or vendor.  You will need to find that out and ask the vendor if the camera supports the protocol or if it uses a proprietary driver.
