Matlab compiler + image acquisition issue

I am currently able to run some code to capture images from a GigE camera on one of my 32 bit Windows machines. I have the following code in one of my functions:

vidObj = videoinput('wininput', 1, 'Y800_1280x960');
src = getselectedsource(vidObj);
set(src, 'Exposure', 10);

When I compile this code and run the exe on another 32 bit machine it doesn't work (after installing MCR on the other machine), unless I change to vidObj = videoinput('wininput', 1), and I remove the line setting the exposure. The first problem I can live with, but I need to be able to set the exposure.

Any thoughts?

Thanks

For the first question, you probably have two cameras - your gige camera and the built-in webcam. You need to get the adapter you want. Play around with this code snippet to adapt it to your needs:

  hardwareInfo = imaqhwinfo % Print what cameras are there.
  adaptorNames = hardwareInfo.InstalledAdaptors;
  % Might look something like:
  % InstalledAdaptors: {'dcam'  'gentl'  'gige'  'lumeneraimaqw64'  'matrox'  'winvideo'}
  matches = strfind(adaptorNames, 'lumenera');
  % Find out which index is the Lumenera Camera.
  LumeneraIndex = find(~cellfun(@isempty, matches));
  theLumeneraAdaptor = adaptorNames{LumeneraIndex}

  hw2 = imaqhwinfo(theLumeneraAdaptor)
  devInfo = hw2.DeviceInfo
  devName = devInfo.DeviceName
  devID = devInfo.DeviceID

For the next question, don't use set(). Simply do this:

src.exposure = theDesiredExposureValue;

That will definitely be it... thanks!

I just picked out a random computer to test distributing on, and it didn't even cross my mind that it would have a webcam.
