I'm using D7 and ImageEn 6.3.0.
I have multiple VM hosts running Hyper-V Server 2012 R2, with client OS instances running Server 2008 R2. For each of the VM instances, my application will crash when it attempts to access MediaFoundationSourceReader, while nearly identically configured OS's running on physical hardware work fine.
The servers obviously don't have a camera, but just accessing MediaFoundation to check for the presence of one causes things to uncontrollably crash.
I've tried wrapping calls to ImageEn.IO.MediaFoundationSourceReader in try/catch, but it still throws an exception.
Any idea what I might be able to do to catch the exception or possibly another workaround?
Here's the stack trace, where I called: ImageEn.IO.MediaFoundationSourceReader.StopCapture;
