It's only supported under Windows, as far as I know.  Try the following patch:

diff --git a/static/galene.js b/static/galene.js
index d2c614c..071f8ba 100644
--- a/static/galene.js
+++ b/static/galene.js

         /** @ts-ignore */
-        stream = await navigator.mediaDevices.getDisplayMedia({video: true});
+        stream = await navigator.mediaDevices.getDisplayMedia({
+            video: true, audio: true,
+        });
     } catch(e) {
         console.error(e);
         displayError(e);

Hello juliusz,
thanks for this new version!
I have a question that is not related to this version in particular.
As operator, when I share a video with `Play local file` the video plays but with no sound for me… Is it a normale behavier?
Many thanks
Éric

No, you should hear the audio of the video.  (I've just tested that it is
the case for me.)

What browser and OS are you using?

Hi all

On osx you can install ishowu to catch the computer sounds and this create a virtual device that is recognized by galene.

 Cheers

I am using Firefox 78.10 with Macos 10.11.8 (as well as Firefox 88 with macos 10.14.6)

I found out that:
- Safari doesn’t show `Play local file`option
- Firefox 78 / 88 doesn’t play the video sound (On Ubuntu with Firefox I get no sound either)
- Chromium 85 doesn’t show the video
- Chrome 90.0 works as expected

Thanks, I'll have a look.

The API is not supported by Safari:

  https://caniuse.com/mediacapture-fromelement

> - Chromium 85 doesn’t show the video

That's a known bug in Chromium.  A workaround is to disable hardware
acceleration.

> - Chrome 90.0 works as expected

That's strange, I was under the impression that the bug hadn't been fixed
yet.

It turns out it's a Firefox bug.

Grr.
