Element-web: Screensharing no longer works in chrome 64

[ara4n]

Failed to get screen-sharing stream: NotAllowedError: Invalid state - despite having the plugin installed.

[lampholder]

I couldn't reproduce this - after https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-permissions-in-cross-origin-iframes, access to the mic and the camera is blocked, but I could still screenshare.

Ah; not the jitsi screen share - the shift-click-on-the-video-call-button screen share.

Yeah; this is broken but it's not a scalar thing.

Seems permission problem can be fixed using new getDisplayMedia() API in Chromium v70 https://groups.google.com/forum/#!msg/discuss-webrtc/Uf0SrR4uxzk/uO8sLrWuEAAJ

Hello,
I still have "Failed to get screen-sharing stream: NotAllowedError: Invalid state" on Chrome only.
Chrome Version 73.0.3683.103 (Build officiel) (64 bits)
I also enable on chrome://flags :

• Experimental Extension APIs
• Experimental Web Platform features
  And https://cdn.rawgit.com/uysalere/js-demos/master/getdisplaymedia.html is working well ...

Hope someone can help me to fix the screensharing on Chrome.

The problem is also there on Desktop version: 1.4.2 for Linux...

Is there an update on this?

@polyrain I made a PR https://github.com/matrix-org/matrix-js-sdk/pull/1276/

While this seems to work in Chrome now, the same error message still appears in the riot deskop client. Any ideas how to deal with that?
