I am fighting since several days in order to open a windowed projector with OBS-Websocket.
The OBS-Websocket documentation says that the projectorGeometry is a string for "Size/Position data for a windowed projector, in Qt Base64 encoded format".
I've been searching the Qt documentation and found information on QWindow::setGeometry, but nothing for a string for "Size/Position data for a windowed projector, in Qt Base64 encoded format".
I've tried several combinations of JSON data plus Base64 encoding, but nothing works.
Is there any description or example somewhere?
