Chromium "Share your screen"-Screen stays empty #97

Closed shibumi closed 3 years ago

shibumi commented 3 years ago

Hi, I have very often the same problem. Sometimes the whole screen sharing setup works and sometimes it does not. My setup is the following:

I set the environment variable: XDG_CURRENT_DESKTOP=sway and I have enabled pipewire in my browser. Furthermore I have pipewire02 installed.

Sometimes it works, sometimes it does not. Today it does not work again and I have no idea why: When I try to share the screen via the Microsoft Teams Website in chromium I see the following:

I gathered the following debug logs:

Do you see anything about pipewire in dmesg?

danshick commented 3 years ago

Can you confirm you aren't experiencing this:

https://github.com/emersion/xdg-desktop-portal-wlr/issues/89#issuecomment-788111941

shibumi commented 3 years ago

@danshick Yes I can confirm. This file does not even exist on my machine (Arch Linux)

shibumi commented 3 years ago

@danshick the funny part: When I start "wireplumber" daemon I can see the shared screen in my Chromium, but sharing still does not work.

shibumi commented 3 years ago

@emersion dmesg is empty.. no logs about pipewire.

danshick commented 3 years ago

@danshick Yes I can confirm. This file does not even exist on my machine (Arch Linux)

Hmmm, it should. Maybe that's part of your problem?

λ pacman -Ql | grep pipewire | grep etc

@danshick

.rw-r--r-- 8.0k root  4 Mar 19:47 pipewire.conf

That's what I see. Interesting. Even when I reinstall pipewire on Arch Linux I don't get those files

This is the exact command.. your command is just looking in ALL packages for pipewire... It looks like some other package is providing those.

shibumi commented 3 years ago

@danshick ok interesting. I need the pipewire-media-session-package on Arch linux. I will add this to the xdg-desktop-portal-wlr package. I didn't know thats a dependency.

danshick commented 3 years ago

This is the exact command.. your command is just looking in ALL packages for pipewire... It looks like some other package is providing those.

No, it isn't. If you look at the prefix, it shows what package the file is from. I realized I'm running pipewire-git from the AUR. The current release in pacman isn't new enough to include all of those configs yet.

Either way, it looks like the issue I pointed you to isn't of concern (AFAIK).

If you run systemctl --user status pipewire, what do you see? What about journalctl --user -eu pipewire?

Edit: You may want to redirect that second command to a log file to upload, it could be long.

shibumi commented 3 years ago

Ok.. I installed the missing package. I have the /etc/pipewire/media-session.d/media-session.conf file now and I still have the same issue.

I guess it has something to do with these logs:

2021/03/08 15:52:23 [INFO] - pipewire: stream state changed to "connecting"
2021/03/08 15:52:23 [INFO] - pipewire: node id is -1
2021/03/08 15:52:23 [INFO] - pipewire: stream state changed to "paused"

Why is the stream paused?! When I start the "wireplumber" daemon I get this change in the xdg-desktop-portal-wlr logs:

2021/03/08 15:52:23 [INFO] - pipewire: node id is 120
2021/03/08 15:53:37 [INFO] - pipewire: stream state changed to "streaming"

And THEN I see the shared screen in my chromium, but according to my co-workers it still doesn't work. Mhhh

shibumi commented 3 years ago

The node ID with number "-1" is strange, too...

shibumi commented 3 years ago

@danshick mh Ok I fixed it now I think. I did:

$ sudo pacman -Syu pipewire-media-session
$ vim /etc/pipewire/media-session.d/media-session.conf #uncomment metadata
$ systemctl start --user pipewire-media-session
$ sudo killall xdg-desktop-portal
$ sudo killall xdg-desktop-portal-wlr

This fixed the issues for me :)

Closing, because this is not related to xdg-desktop-portal-wlr. I will add pipewire-media-session to the dependency list for xdg-desktop-portal-wlr + modify the wiki accordingly.

You can see how the node switches from "paused" to "streaming"

@shibumi

I will add pipewire-media-session to the dependency list for xdg-desktop-portal-wlr + modify the wiki accordingly.

~Please don't do that. It is not a strict dependency.~

I might be wrong here as others are reporting the same.

danshick commented 3 years ago

I think your actual issue may have been here:

Mar 08 14:49:38 motoko.shibumi.dev pipewire[18513]:   Prop: key Spa:Pod:Object:Param:Format:Video:format (131073), flags 00000000
Mar 08 14:49:38 motoko.shibumi.dev pipewire[18513]:     Id 25       (Spa:Enum:VideoFormat:GRAY8)

For some reason, it looks like xdpw was reporting that your pixelformat was in grayscale? Could that be possible? Do you have a grayscale display of some sort? Or maybe this is negotiation from a grayscale capture device?

Anyway, Chromium does not support that pixel format. That may have had something to do with your issue. I'm not sure why adding pipewire-media-session fixed your problem.

freswa commented 3 years ago

Same issue here and there is no grayscale display, just 1920x1200 color displays. Installing pipewire-media-session resolved it.

danshick commented 3 years ago

Okay, maybe it is strictly required on Arch.

The problem with updating the dependencies is that the git version doesn't split out the required component into a separate package.

We'll have to see at the next pipewire release what the package composition looks like. We can note this in the wiki for now though.

Nope, no grayscale capture device.
