I use a FireWire-Camera and i want to display the frame in real time (15 ~ 30fps) by Qt. I have tried to display it by QGraphicsview, e.g.:
graphicsview->scene()->addPixmap(pixmap);
graphicsview->scene()->addPixmap(pixmap);
To copy to clipboard, switch view to plain text mode
But it is too slow. And i have tried to use "setBackgroundBrush", e.g.:
graphicsview
->scene
()->setBackgroundBrush
(QBrush::QBrush(qimage
));
graphicsview->scene()->setBackgroundBrush(QBrush::QBrush(qimage));
To copy to clipboard, switch view to plain text mode
This is faster, but not real time.
Can anyone tell me some advices how to solve the tempo problem?
Thanks!
