Does it work on wayland?

According to the errors, it seems like your system doesn't have the required interface for screencast

dineshkp · 2021-10-06T10:35:33Z

@SeaDve Appreciate the quick response!

I switched to wayland and faced the same issue. Attached screenshot. How can I resolve the missing interface for screencast ?

dineshkp · 2021-10-06T10:36:43Z

If it may help: It was working fine in the previous version prior to 2.0.0

SeaDve · 2021-10-06T10:39:41Z

I am afraid that your distro may not support the new implementation.

You can also test it further with https://mozilla.github.io/webrtc-landing/gum_test.html to tell if only Kooha is affected. In the gum_test website you can test Screen Capture.

While it is not working, you can downgrade using flatpak update --commit=e52aeb30b4d9f97436de184b6703ae83c48468880d95f0b74916cd6fca3e7c2a io.github.seadve.Kooha to 1.2.1

dineshkp · 2021-10-06T12:41:10Z

This the result, when on Wayland.

Could there be any other issues ? Please let me know if any other information will help debug this issue. I would love to help.

SeaDve · 2021-10-06T12:42:08Z

Does kooha work on 2.0.0 wayland?

dineshkp · 2021-10-06T14:45:22Z

Does kooha work on 2.0.0 wayland?

The image in this post shows kooha 2.0.0 running on wayland

dineshkp · 2021-10-06T14:54:41Z

I checked (googled) the error in the debug log and came across this related issue

flatpak/xdg-desktop-portal#446

The discussion in the bug report provides better clarity:
https://bugs.launchpad.net/ubuntu/+source/xdg-desktop-portal/+bug/1879580

But as per the later report, screencast should work fine on x11, Which I am still facing an issue. Maybe I need to wait for a stable release of xdg-desktop-portal to sort out this.

Does kooha run on x11? Asking since you requested a check on wayland at the start of the discussion.

SeaDve · 2021-10-06T15:16:09Z

it should work on both. I think it is still weird though that it works on chrome, but not Kooha, so I think it is an internal issue with Kooha, ill investigate on it, thanks for detailed info!

dineshkp · 2021-10-07T02:19:13Z

In the meantime, I will be using version 1.2.1

The downgrade instructions specified in this post works fine.

Thank you @SeaDve

YukKevChuHau · 2021-10-12T02:19:22Z

I've gotten the issue too since the 2.0.0 update. I'm also on Zorin OS 16.
I also downgraded to v1.2.1 and it works now.

JumperLuko · 2021-11-10T22:04:01Z

Same problem on Zorin OS 16, downgrade works fine

Use the mask after downgrading, for not to update

sudo flatpak update --commit=e52aeb30b4d9f97436de184b6703ae83c48468880d95f0b74916cd6fca3e7c2a io.github.seadve.Kooha
sudo flatpak mask io.github.seadve.Kooha

And then if you want remove mask
sudo flatpak mask --remove io.github.seadve.Kooha

starsareintherose · 2021-11-26T01:49:25Z

When I use the 1.2.1, the part of section reports

I'm afraid that the only fix is to update to 2.0.0

In gnome-shell 41, the SelectArea is now private, so apps cannot access it anymore

starsareintherose · 2021-11-26T01:55:19Z

THen it occurs same issue with 2.0.1

Notice #140

develroo · 2021-12-08T17:41:38Z

If I might jump in here. I too have a problem both with Kooha and OBS so it strikes me it must be something to do with pipewire/wayland though I am at a loss what as I went through the troubleshooting steps, but they all check out.

The error I get on start is similar to above

ERROR kooha::backend::screencast_portal > Error from screencast call: Response(Other)

If we could work out what response it is getting maybe we work out what we are supposed to be expecting. Is there anyway to get this debugging information ?
1.19.0-2+b1
EDIT: Oh FTR I am using Kooha 2.0.1 Flatpak on Debian 11 testing with xWayland 2:21.1.3-1+b1 and libwayland-server 1.19.0-2+b1 on kernel 5.15.5-1

kojid0 · 2021-12-14T08:37:03Z

Facing the same problem.
Want to report that I was able to use v2.0.1 until yesterday. My guess is that some recent update of ZorinOS broke it (for me).

develroo · 2021-12-14T13:52:44Z

Well I am currently also seeing a problem with the flatpak OBS not seeing any pipewire-window-capture-source so I suspect this is all related. I raised an issue with them as well.

develroo · 2021-12-17T10:40:54Z

UPDATE: I have just been chatting to the flatpak OBS guys and they suggested I checked if I had xdg-desktop-portal{,-gnome,-gtk,-kde} installed. It turns out xdg-desktop-portal-gnome was NOT installed by default. So I installed it and restarted Gnome and now Kooah works again!

So please, everyone check to see if your desktop xdg portals are installed, if not install them and restart the destop. With luck it should work.

WhiredPlanck · 2022-01-05T00:35:57Z

@develroo I've installed xdg-desktop-portal-gnome and started it's systemd service, but my Kooha 2.0.1 still doesn't work (both installation via native package manager and Flatpak) , reporting the same error like yours ('Other Response'). My DE is KDE Plasma 5.23 (X11), all xdg-desktop-portal- things are installed and their systemd services have started. I have no idea if Kooha can only work with GNOME......

Did you logout/login again and reboot. It is not a service that is dynamically started and detected. You have to restart the gnome session.

Edit: Oh I just noticed you said you are using KDE then you need the xdg-desktop-portal-kde package.

WhiredPlanck · 2022-01-07T08:38:42Z

No, I didn't...... I'll give it a try, thanks.

@SeaDve Hi Dave, I just installed Kooha flatpak after hearing about it and I too am having issues getting it to record due to "Other" portal request failing.

When I start Kooha via the terminal and press record, this is what is printed:

 ERROR kooha::backend::screencast_portal > Error from screencast call: Response(Other)

In the pop-up that appears saying for "Other" portal errors check the link, which I did. https://github.com/SeaDve/Kooha#-it-doesnt-work

However I am running the flatpak, I shouldn't be missing any dependencies. On top of that, I used flatseal to give every single permission possible and the "Other" response persists so I'm not sure what could be the portal error besides what I suggest below:

From looking this issue up online, I believe the flatpak needs the permission "xdg-desktop-portal", "xdg-desktop-portal-kde" for me and "xdg-desktop-portal-gnome" if on Gnome. These are not present by default and should probably be added. At least they are not present by default in the latest version I received from Flathub and I am not sure where I would put them in flatseal as I am still new to Linux.

I already had the required packages installed. It just seems like the flatpak cannot communicate with them.
xdg-desktop-portal 1.12.1-1
xdg-desktop-portal-kde 5.23.5-1

Flatpak: 2.0.1

Thank you.

jakubklos77 · 2022-03-07T08:04:56Z

I have had the same problem for a long time. Thought this was an issue of Kooha but it is not and I figured this out after upgrading to Ubuntu 22.04 beta (didn't work on 20.04 either).

There are a few requirements you need to meet

xdg-desktop-portal and xdg-desktop-portal-gnome must be installed. The latter was not in my case
gstreamer needs a registered pipewire plugin (even though gstreamer1.0-pipewire was installed gstreamer did not pick it up no matter what I did). "gst-inspect-1.0 pipewiresrc" this must work. I had to move the libgstpipewire.so somewhere else, start gstreamer, move it back and only then it was picked up. Don't ask me why
My system was missing these 2 packages as well
pipewire-media-session libpipewire-0.3-common
Even though it seems they are not needed, they are in fact.

When all of these are met Kooha works properly via flatpak.

Tried your suggestions but:

couldnt be found or installed, i use pureos 10
followed steps in 2. no cigar, also gst-play command to start gstreamer doesnt work for me, how do you start gstreamer?

@develroo Sorry for very late reply. But the result is still that the app cannot start up a recording.

develroo · 2022-10-12T17:55:48Z

Not sure what to say then. As you can see from the attached screencast it is working for me with Kooha. But I am using Gnome so? shrugs

lifeiscontent · 2022-10-20T16:07:05Z

it seems Zorin OS 16 only has 1.8.1 available in its apt repositories and in order to build xdg-desktop-portal-gnome it needs >= 1.15.0

not sure how to get around it without a bit of manual intervention (e.g. build all of these dependencies from their respective repos)

tungdt-90 · 2023-08-19T18:43:21Z

The downgrade is unfortunately not working anymore, I've got 404 error with that commit hash. Also, the oldest version I found with flatpak command is 1.2.1

Does anyone have any other solution?

sysfu · 2023-08-28T16:09:44Z

I was able to get the downgrade to install v2.1.1 via flatpak just the other week on elementary os 7x, however it didn't resolve the recording issue, still got this error with it.

@sysfu It was my mistake, so sorry. I mean v1.2.1

But anyway, I switched to Kazam, it works well and can record 60 fps. which Kooha 1.2.1 still has some problem

SeaDve · 2024-02-08T12:34:28Z

Closing this since there is nothing much we can do from Kooha's side here, aside from providing more helpful issue messages.

KaKi87 · 2024-02-08T14:20:43Z

So what's the solution to this issue ?

SeaDve · 2024-02-08T14:31:37Z

So what's the solution to this issue ?

See #129 (comment)

KaKi87 · 2024-02-08T14:46:53Z

Thought this was an issue of Kooha but it is not

Actually it is, because dependencies should be automatically installed when installing Kooha, which is the purpose of package management.

SeaDve · 2024-02-25T03:31:48Z

Actually it is, because dependencies should be automatically installed when installing Kooha, which is the purpose of package management.

That's more of a packaging issue, not an application issue.

In Flatpak at least, installing flatpak would bring xdg-desktop-portal and, therefore, the required pipewire libraries with it, so it won't be possible to install Kooha in the first place without having those dependencies installed.
