How to display gpumat image in opengl widget

[Imran B]

Hi all, I'm trying to display video rendering in opengl widget. I have done that before without opengl using opencv and qtwidget. But when checking performance everyone suggested opengl will be more faster. I'm having Nvidia rtx 2080. And I'm rendering and converting the image with cuda methods. Now my task is to directly feed gpumat in qtwindow. Please give me your suggestion, if you post code too it's appreciatable. thanks in advance!

@SGaist hi , I'm using opencv cuda it returns gpumat. I don't know how to check which gpumat?

What processing are you doing with OpenCV ?
