Could not start recording

[conde2]

Peek: 1.3.1
GTK: 3.22.28
GLib: 2.54.3

Details:

Could not start recording, already an active recording using org.gnome.Shell.Screencast?

OBS:
I have both installed x264 codec and gstreamer ugly plugins

running with: peek -b ffmpeg it does not show the error but only records the mouse pointer moving and a black screen behind

OS: Arch Linux

Please take a look at the logs in journalctl, gnome shell should report some more details about the error.

running with: peek -b ffmpeg it does not show the error but only records the mouse pointer moving and a black screen behind

That indicates you are using Wayland, ffmpeg cannot record on Wayland.

@conde2 You are missing the x264 codec. On Arch you need to install gst-plugins-ugly for this.

[conde2]

I've installed it and x264 codec and still have the same problem.

Again we need the output from gnome-shell in the journal, otherwise it's just guessing. Could be the same issue, could be something different now.

It is possible that gnome-shell needs to be restarted after the plugins have been installed, not sure about that.

If you are on wayland, you need to log out and log in, since there's no way to restart gnome shell "live", as you could on X.
