If i have a QGraphicsScene (not necessarily connected to a view, or if
required, an OFFSCREEN view), can i set its output as the input to a
QMediaCaptureSession?
I see i can connect a QWindowCapture, but must that window be showing? can that
window be invisible? eg: h.264 output in the background, unrelated to the
showing (visible) windows?
I had asked this question
<https://forum.qt.io/topic/138386/export-h-264-from-qgraphicsscene/6> a couple
years ago, but times have changed and i wonder if it is now possible?
if it is not possible from QGraphicsScene directly, then how about a temporary
buffer of QImage? Can i feed QMediaCaptureSession a QImageCapture class, then
feed the QImageCapture class a series of QImage or QVideoFrame refs?
is there sample code for sending in-memory images into QMediaCaptureSession ?
