Please note that this is a list mostly about Qt Creator usage and development. On the inter...@qt-project.org mailing list you’ll probably reach more people that are interested in developing applications with Qt. That said: > Is there any way I can get QWidget frames in YUV format? Without conversion. > I am working on QT 5.5. Any advice ? If you really get that from a screen, that will need to be converted _somewhere_. On the other hand, QImage is a QPaintDevice and supports different image formats. So it is possible to render a QWidget (+ its child hierarchy) directly into a QImage by using the QWidget::render(....) method, similar to printing a widget: https://doc.qt.io/qt-5/qtprintsupport-index.html#printing-widgets . I’d expect that to be as direct as it gets.
