How to solve the deployment issue about QT creator? - windows

Question

I am going to deploy the QT creator project. But I discovered that some functions of deployment .exe are missing. However, it originally works inside the QT creator. I have no idea about how to solve the current problem, like using what tools to help. The missing function is that the program doesn't show the thumbnails about the video files, where I have assigned the relative images to that.
