Describe the bug

1. After clicking on the Record I see Screen Share window with monitor selection

Why do I need a Screen Share?

2. After selecting a monitor and slicking Share I see an error:

What is Screencast Portal? Why the app needs it?

I have the same error except it happens when I press "record".

Why do I need a Screen Share?

That window is from the desktop environment. Kooha asks the desktop for the screen, and after you agree, the desktop shares the screen data to Kooha to be recorded.

---

Apart from that, I'm also hitting the same error, both with Kooha installed with Flatpak (from Flathub) and with the Arch Linux package.

This is the output from the command:

$ env RUST_BACKTRACE=1 RUST_LOG=kooha=debug GST_DEBUG=3 PIPEWIRE_DEBUG=3 kooha

The error is emitted here:

My system uses X11, and uses PipeWire as the audio server. Perhaps ashpd::desktop::screencast simply doesn't support this situation?

That window is from the desktop environment. Kooha asks the desktop for the screen, and after you agree, the desktop shares the screen data to Kooha to be recorded.

I think it's not very user-friendly, the app should start record immediately like other similar apps e.g. Peek.

@SeaDve any solution for this error?

This would be fixed now on the main branch

Closing this as #129 duplicate for now. Also this comment might be helpful

v2.1.0 Flatpak, the app doesn't work: after selecting monitor and clicking Share

1: Failed to begin ScreencastSession
2: Failed to start screencast session
3: Interaction was ended in some other way with response VariantDict({})

[SeaDve]

That is likely missing runtime requirements in your host system like GStreamer pipewire

@SeaDve

I have the same error and gstreamer 1.0 and latest version of pipewire are installed.

Environment: kooha flatpak, pureos 10, arm64 mobile, Debian Byzantium, phosh 0.21, kooha 2.2.2, 200% scale, wayland 1.25.

Steps to repeat:

1. install flatpak app,
2. open app,
3. select any screen record function

PS: the copy log does not work and the log details are sparse.

v2.2.2 Flatpak. The app don't work for me.

[CaptainMorgan12]

I wonder if this should or could be reopened the suggestions referenced dont really work.

[Solarunit]

I think there should be a new issue, because the error is different now. The app never worked for me...
