Hi and welcome to devnet,

If excluding Qt from your application, can you successfully open that video file ?

Is the path correct ?
Is the file in good shape ?

ElifOzkan

Yes I can open the file and path is also correct but I dont know what is the good shape for Qt.

By the way, now I am using webcam of my laptop and it works. Difference is the source.

VideoCapture(0);

Can you should the whole code you are using for the Qt version of your application ?

ElifOzkan

This is my whole code actually and I am using QT 5.15.2 with 5.0.3 QT Creator and My OpenCV is 4.5.4.

No it's not since there's nothing that invokes your function in what you posted.
