Web pages can expose Media Session API, it is using for lock screens notifications and also for changing playing status directly on the page
https://developer.mozilla.org/en-US/docs/Web/API/Media_Session_API
You can see what I mean by playing youtube video on Fire Fox or Chromium based browser and in console run:
navigator.mediaSession.metadata
Is it possible to retrieve such data in page loaded in QWebEngineView / QWebEnginePage? I want it back to the C++. Also, I want even more, I want to hook on this data and get notified when metadata changed or when navigator.mediaSession.playbackState changed
