I'm trying to display a video in a QGraphicsView with a QGraphicsVideoItem to add something like an OSD on top of it and it works well but the quality of the video.
It seems that the video is oversized (even if I put it at the same native size) and let appear some pixelization. I tried in a VideoWidget and this one doesn't shows this kind of problem, but I can't put a correct overlay on that kind of object.
Any ideas on what can be the problem in a graphic view ?
(I'm on windows, Qt 5.7)
