playbin - blank areas on screen and various questions

Try to add this to your widget:
void <YourWidgetClassName>::paintEvent(QPaintEvent *event)
{
    overlay->expose();
}


void <YourWidgetClassName>::resizeEvent(QResizeEvent *event)
{
    overlay->expose();
}

Where overlay is your GstVideoOverlay.

These two overrides are essential.
The paintEvent() is needed when gstreamer is not playing the video.
The resizeEvent() is needed to let gstreamer know that the widget size has changed.

 Philippe, I have looked at your code and it's much too heavy for me.
I have copied the following lines but that's not enough - the blank spaces are still there:

    setAutoFillBackground(true);
    setAttribute(Qt::WA_OpaquePaintEvent, false);
    setAttribute(Qt::WA_PaintOnScreen, false);

If GStreamer does not use all the overlay's window, why does it never paint the rest ?
Is my only solution left is to resize the display window to be exactly covered by the video?
