VideoWidget
-
Hello, I am using the grabToImage() feature of VideoWidget to acquire Overlayed images. Actually I am using this for recording a video. My question is, can I use this method to grab 4K images. I am able to use the grabToImage() feature of QT/QML to acquire up to Full HD. But when I move into 4K zone I see grabToImage() struggling and causing the whole system to suffer. FYI, I tried using this with i5, i7 and even i9 CPUs and a humongous RAM and GPU combo. Still I see QT/QML struggling.

I think you should use some other method for this.
grabToImage()is not designed for video creation. Research some other, more generic screen capture techniques. I'm sure there are some libraries which are well suited for this, since screen capturing and streaming is very popular nowadays. -
As I said in my original post, I have crossed FHD recording, the issue is with 4K... I want to understand whether QT/QML has the capability to support this...
