    Hello!

    I have raspberry pi 4 and bookworm operating system on it. I am using Qt's QMediaPlayer class and QCamera class to record video. Problem is when resolution comes to (1280 x 720) there is a lot of lags on program and on recorded video. I use performance monitor and see that my recording process only use CPU(%70 -%80 of it) and I think that my be my problem. My goal is to record high resolution videos(1920 x 1080). Is there a way to achieve it? Does using gpu may solve my problem? How can I make raspberry pi use gpu to record video?

    Thanks in advence.
