Hi,

I'm a newbie to OpenGL and I'm currently using the class provided by Myzhar to display a cv::Mat in my GUI.

Now I want to overlay the videostream with a second partly transparent layer containing multiple line segments. Those cv::Mat images come at another framerate as the videostream.

What is the best way to do this and how to I have to adapt the code to make it work?

Thank you!
