Navigator.MediaDevices.getDisplayMedia() is not present.

Hello,

I'm not sure how to edit the types (I can't find reference to navigator anywhere), but your output is incorrect. The navigator.mediaDevices object should have a getDisplayMedia(constraints) method that returns a Promise<MediaStream.

See here: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getDisplayMedia

This has been an issue in the main typescript library for some time now: microsoft/TypeScript#33232 .

It seems like Typescript's files are generated by this library. This should be an easy fix for someone who knows what they're doing. Alternatively, point me to where the navigator.mediaDevices types are defined and I'll do it myself.

If that's the case why do you include navigator.mediaDevices.getUserMedia? By admission of the document you linked, that's also a draft.

But https://github.com/microsoft/TypeScript-DOM-lib-generator#additions also says:

A feature needs to be supported by more than two major browser engines to be included here, to make sure there is a good consensus among vendors: Gecko (Firefox), Blink (Chrome/Edge), and WebKit (Safari).

And about W3C Working Draft:

If it's at Working draft the additions available in all three of Firefox, Safari and Chromium

But according to Mozilla MDN (https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getDisplayMedia) this feature supported by all of these browsers since end of 2019.

Looks like getDisplayMedia is included in the current build of the main branch.

Yeah, #1034.
