navigator.mediaDevices.getDisplayMedia({
    audio: false,
    video: true
  }).then(gotMedia).catch(function(e) {
    console.log('getDisplayMedia() error: ', e);
  });

when executing the above code it prompts with a popup asking user to select what to share. Can we get rid of that popup and directly get the stream of the entire screen?

Would be glad if someone can help with the same. Thanks in advance

• one word ... security get the stream of the whole puter ... the what? the stream? I've build hundreds of puters in my time, and not one contains a stream (except that time I screwed up a connection on the water cooling, but that was more of a leak) – Jaromanda X Commented Sep 18, 2020 at 13:03

• so, you addressed the frivolous part of my ment, and decided there is no security issue with what you want to do? Do you understand why this would be a bad thing? – Jaromanda X Commented Sep 18, 2020 at 13:18
• Sorry could not figure out your ment first. Yes I know there is a security issue. Still I need clear idea on this. Can you please explain a bit in detail. Thanks – Pradipta Dey Commented Sep 18, 2020 at 13:24
• 2 Yes but in case of getUserMedia to access camera we provide the authentication once and after that the browser does not ask for the same. But for the getDisplayMedia it is not the same. It always asks even if we are using the same tab. – Pradipta Dey Commented Sep 18, 2020 at 15:35
