Recording doesn't start gnome 40 (x11)

[lefred]

Thank you for porting the extension to Gnome 40 \o/

In the open points, I see "There is a problem with the gstreamer pipeline - fixed. Gnome Shell 40 needs a videoconvert element first".
Not sure if it's related, but I can install the extension, I can get the parameters, ... all fine. But I'm not able to start recording:

I tried different output format too.

I'm using Fedora 34 with gnome-shell-40.4-1.fc34.x86_64 (Using Xorg)

I've experienced timeouts as well, but I could only reproduce it when switching from a wayland session to a x11 session. In a wayland session, screencast works immediately.

Can you record with the standard gnome screencast shortcut? ctrl+shift+alt+R
Does this create a webm file in $HOME/Videos?

I could get it eventually work with a small number of retries. At some point, it suddenly starts working... After trying a couple of times ctlr+shift+alt+R - once this works, then EasyScreenCast also started working.

[lefred]

In wayland it works as expected (the native gnome screencast and Easyscreencast), on Xorg, none of them are working.

another case (from #292):

@Avijneyam
it's X11
Kali Linux
Gnome-Shell 3.38.6

[lefred]

It's working now for me. Nothing special done, I used wayland for some days and now back to X11 and it works as expected.

Maybe this URL will help to troubleshoot: https://github.com/emersion/xdg-desktop-portal-wlr/wiki/%22It-doesn't-work%22-Troubleshooting-Checklist
I've not had time yet to check this X11 problem...

@Avijneyam FYI

[adangel]

@Avijneyam I've tried to reproduce it on Kali Linux 2021.3a and gnome-shell 3.38.4 under x11. But that works out of the box. The only way I could make it fail was, when I manually stopped the service "pipewire-media-session". Can you check, whether this service is running for you?

systemctl --user status pipewire-media-session

It should say "Active: active (running)".
If it is not running, try to start it with systemctl --user start pipewire-media-session

If I update Kali Linux now, I'll get gnome-shell 41, so - maybe you should update your Kali as well and the problem is gone?

[Avijneyam]

Thanks @adangel for mentioning me and sorry for late reply...
i've checked that cmd output and it's showing this

Failed to start pipewire-media-session.service: Unit pipewire-media-session.service not found.

also i've updated Kali

Gnome: 41.2
X11

still this ext. not working for me
