I have some problems. If I evaluate imaqhwinfo('winvideo'), the problem ocurrs as following,

>> maqInfo = imaqhwinfo

maqInfo =

Answer 1

[Image Analyst]

Worked fine for me in R2013a. Since you have such an old version that means you're probably not paying your support contract so you can't even call them and get help. If you do have a support contract in force, then just upgrade to R2013b and see if that works (though not if you have the compiler - if you do, ask me first).

Answer 2

[Dennis]

We get the same issue now on R2014b when calling imaqhwinfo('winvideo'), whereas imaqhwinfo() or imaqhwinfo('pointgrey') still work fine. Previously 'winvideo' also worked without a glitch. We did not change any drivers before. Updating the support package did not help...

[Image Analyst]

Not sure why you flagged my answer to Kim (where I suggested upgrading to a version I know works or else asking tech support) as unhelpful. How does your answer help her more than mine? Sounds like it should be another question, rather than a helpful Answer to her.

Anyway,...I don't know about older versions, but with the latest R2015a version, to get the generic winvideo interface, like for your integrated webcam, you need to install the support package. So do

>> supportPackageInstaller

then select the "OS generic video interface" or something like that. Install it, and then imaqtool should have the winvideo adapter. Since Dennis has a fairly recent version, it might work the same way for him. Not sure why this is not done automatically with the installation of the Image Acquisition Toolbox, but it's not.

Hope this helps someone. Dennis, since your release is less than a year old, you should definitely have Tech support still active so feel free to call them - after all, you've already paid for the help in advance.
