QtMEL & Visual Studio 2013

Using Qt 5.6 and Visual Studio 2013, would I need to manually build your libraries, or can I use the provided prebuilt libs?

Hello. Unfortunately, you need to build it manually.

I appreciate the quick response! I am looking for a solution to:

• Record (and output) multiple live camera streams
• Display current camera feed
• Perform image subtraction to support motion detection

Would your libraries be able to handle multiple cameras at once? Also, since you have worked with OpenCV, do you know if it a simple process to convert from a QImage to an image that OpenCV can use in order to subtract images? Thank you for the assistance!

Yes, all you need is to create a new image grabber(by subclassing AbstractImageGrabber) or use CameraGrabber(if it suits). Then just create any quantity of grabbers you want (how many cameras you have).

Also, since you have worked with OpenCV, do you know if it a simple process to convert from a QImage to an image that OpenCV can use in order to subtract images?

It is quite simple when we have ready solution :) Here it is: https://umanga.wordpress.com/2010/04/19/how-to-covert-qt-qimage-into-opencv-iplimage-and-wise-versa/
