Support new recording interface for GNOME 3.38

[eminfedar]

There is only black screen on Debian Testing, Gnome Wayland, 1.5.1 version. Can't record anything.

[Santinell]

Have the same problem. My system Manjaro Gnome Looks like Wayland became default for Gnome DE

Same in Fedora Silverblue 33 with the flatpak version. It only records a black screen and the mouse pointer.

[emanuelhfarias]

same with Fedora 33 installed via RPM. Fedora 33 uses wayland by default.

i have the same issue with ffmpeg backend. i would recommend people here to use peek --backend=gnome-shell in the meantime

[adrm]

@plowpath wow, I didn't know about that issue. That means it's working when launching from the terminal with that command. Is there a way to set that backend as the default? Peek's preferences do not allow that setting. I suppose editing the desktop file would work, but is there anything GUI-user-friendly?

The problem is that the latest GNOME release ditched the old DBus interface for screen recording and provides a new one. This is not yet reported. The only workaround currently would be to run with Xorg instead of Wayland and use the ffmpeg backend.

What is the default recording backend on Wayland? Is there a terminal command to check for what recording backend peek was configured by a particular distro?

I ran in the same issue on Arch with Wayland. Only the cursor is recorded. The workaround peek --backend=gnome-shell does the job for me too.

Failed to initialize recorder: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

And without arguments I only got the cursor at recording

[taoqf]

even record mp4 with peek --backend=gnome-shell will blocked before recording. fedora 33 https://github.com/phw/peek/issues/695

Might be an idea to send a feature request to ffmpeg to support the Wayland / PipeWire / xdg-desktop-portal way of screencapture and/or this custom GNOME interface.

For those who want to set --backend=gnome-shell for the desktop launchers, do cp /usr/share/applications/com.uploadedlobster.peek.desktop ~/.local/share/applications/; cp /usr/share/dbus-1/services/com.uploadedlobster.peek.service ~/.local/share/dbus-1/services/ and then change these local files adding --backend=gnome-shell to the Exec=... line.

@bphd do you have gst-plugin-gtk and gst-plugins-ugly installed? What's your gnome-shell version?

Works for me on Ubuntu 20.10 with GNOME 3.38. Just recorded a GIF after installing via PPA and the saved GIF looks good.

peek --backend=gnome-shell doesn't work for me on Manjaro with Gnome 41.3 on Wayland

App starts fine. But as soon as recording starts, it just hangs. In some time the dialog appears with info that app is not responding.

That is for both app versions from official Manjaro repositories and Flatpak.

Update: Looks like my experiments with backends interfered with results for Flatpak version. After rebooting and starting fresh Flatpak version of app, as soon as recording starts, I get ffmpeg error:

Command "ffmpeg -f x11grab -show_region 0 -framerate 10 -video_size 525x349 -i :99.0+367,112 -filter:v scale=iw/1:-1 -codec:v libvpx-vp9 -lossless 1 -r 10 -y /home/user/.var/app/com.uploadedlobster.peek/cache/peek/peekNO0UG1.webm" failed with status 256 (received signal 0).

From what I've understood it's not "not planned". It's not for WayLand but for Gnome, so planned for that issue
