Did you ever call liten on the server side? Literally server.listen(); I used a different module, express-ws.   You need to have something listening on the port, then the server can map the incomming request to the correct handler. I use the following (incomplete code) to broadcast activity to

Try a QVideoWidget? http://doc.qt.io/qt-5/qvideowidget.html I'm in a similar situation, but there's a few differences. As far as I can speak to what you want: I have a QAbstractVideoFilter that gets sent frames continuously, but only captures some of them. Which ones are controlled by a
