Description Georges Stavracas 2021-11-21 20:16:22 UTC

Recently xdg-desktop-portal gained the screencast session restore feature, but it requires frontends to implement that. So xdg-desktop-portal-kde needs to send `restore_data` back to xdg-desktop-portal when a permission mode is passed.

There is a reference implementation in xdg-desktop-portal-gnome that is merged already: https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome/-/merge_requests/14

You can use libportal's mainline branch to test this feature, since it's landed support for it too.

Thanks for letting us know!

Comment 2 Prajna Sariputra 2022-03-12 23:33:16 UTC

OBS has implemented support for this feature as well, looks like it's already there since version 27.2.0: https://github.com/obsproject/obs-studio/commit/26f1bfd05f2782d0e99a4a044b90bbb6b62b329a
