Description of problem:
Screen sharing is broken

Version-Release number of selected component (if applicable):
firefox-82.0.2-1.fc33.x86_64
pipewire0.2-libs-0.2.7-4.fc33.x86_64

BTW: gnome-screencast reording (Ctrl+Alt+Shift+R) works
Comment 3 Milan Zink 2020-11-04 20:58:48 UTC 
Hi,

so the problem is with pipewire.

Works without issues with following versions:
firefox-82.0.2-1.fc33.x86_64
pipewire0.2-libs-0.2.7-4.fc33.x86_64
pipewire-0.3.13-4.fc33.x86_64
pipewire-gstreamer-0.3.13-4.fc33.x86_64
pipewire-libs-0.3.13-4.fc33.x86_64
xdg-desktop-portal-1.8.0-1.fc33.x86_64
xdg-desktop-portal-gtk-1.8.0-1.fc33.x86_64

pipewire-* 0.3.14-2 downgraded to 0.3.13-4.

Screen share works with downgraded pipewire
Comment 5 Milan Zink 2020-11-04 21:16:55 UTC 
Works fine also with chrome/chromium based browser with: chrome://flags -> WebRTC PipeWire support: Enabled.

I think Component: needs to be changed to 'pipewire'.
