convert QVideoFrame to QImage

Question

so I used videoFrameProbed

Answer 1

You can use QImage's constructor:

 QImage img( currentFrame.bits(),
             currentFrame.width(),
             currentFrame.height(),
             currentFrame.bytesPerLine(),
             imageFormat);

Where you can get imageFormat from pixelFormat of the QVideoFrame:

 QImage::Format imageFormat = QVideoFrame::imageFormatFromPixelFormat(currentFrame.pixelFormat());
