Other Screen cast not working with OBS-studio in Hyprland "warning: [pipewire] Failed to start screencast, denied or cancelled by user"

H

Hippoids

Hello. I am new in FreeBSD and also BSD-based sytems too...

I have installed OBS-Studio, XWayland, wlroots, Hyprland and also `xdg-desktop-portal-hyprland` from `pkg install`.
But after trying to create a `Screen Capture (PipeWire)` source and choose the first my monitor - I have nothing.
And when I do it, this warning appears in the terminal.
```
info: PipeWire initialized
info: User added source 'Screen Capture (PipeWire)' (pipewire-screen-capture-source) to scene 'Scene'
info: [pipewire] Screencast session created
info: [pipewire] Asking for monitor and window
warning: [pipewire] Failed to start screencast, denied or cancelled by user
```
But I have NOT denied or cancelled screencast.
How to solve it?

Hi Mate

im running obs studio on wayland using dwl on freebsd 14.1 p5

do you have dbus enabled in your rc.conf

Code: 
/etc/rc.conf

Code: 
dbus_enable="YES"

i use Wayland output (dmabuf)

do you have the following packages installed

Code: 
seatd wayland-protocols wayland wlroots qt5-wayland

XWayland is for using X applications on wayland
 
On swayfx, this is what I do:
First I launch pipewire, then I launch /usr/local/libexec/xdg-desktop-portal-wlr.
Once all of this is done, I launch obs and use pipewire for screen capture.

I use pipewire too.
Btw I just tried to launch pipewire from term and see some errors, maybe it can be useful..

hi mate

i dont manually start pipewire
you shouldnt need to

i found those errors as well with pipewire

this is how i start dwl

Code: 
exec dbus-launch --exit-with-session dwl -s 'dwlb -font "monospace:size=16"' 2>/dev/null

can you start hyperland like this exec dbus-launch --exit-with-session
and see if that resolves the issue

Code: 
exec dbus-launch --exit-with-session hyperland

i use a script called dwl-start to start dwl
i dont use a gui login manager

Code: 
#!/bin/sh

# start dwl with dbus
exec dbus-launch --exit-with-session dwl -s 'dwlb -font "monospace:size=16"' 2>/dev/null


Also what version of Freebsd are you using

freebsd 14.1 automatically creates the XDG_RUNTIME_DIR and exports it
in previous version of freebsd you had to manually create the directory and export it in your shell

Code: 
printenv

Code: 
XDG_RUNTIME_DIR=/var/run/xdg/djwilcox
 
Don't run them as root, all of them should be on the same user, with the same dbus address.
The advantage of running pipewire on the foreground is to be able to see what is connecting directly.
So you can see if something happen when obs start.
Also does the screen capture work with a web browser ? If it does not, then the issue is not from obs.
 
You have to, if they are not started (in my case, pipewire is not started, so xdg-desktop-portal-wlr does not start, while xdg-desktop-portal-gtk does start).
Anyways, by looking at your screenshot, it appears that you use the wlr plugins for obs: multimedia/wlrobs.
This plugin is no longer necessary if you have a correct pipewire setup.
 
your right im using wlrobs packages

even with pipewire and the xdg-desktop-portal-wl started

Code: 
pipewire &
/usr/local/libexec/xdg-desktop-portal-wlr &

the only 2 options i have for Wayland are

Wayland output (dmabuf)
Wayland output (scpy)

Video capture device (pipewire)
is for a camera not a screen capture

i did actually mention in a forum post a while ago if pipewire worked for screen capture
at that time it didnt

has something changed in the meantime

This plugin is no longer necessary if you have a correct pipewire setup.
Click to expand...

i played around with pipewire and wireplumber on freebsd and a linux jail
but didnt have any luck

do you have another option listed for wayland screencapture in obs

maybe i dont have option because im using wlroots

obs log

Code: 
[pipewire] No captures available


20241027_20h48m52s_grim.png
 
im using dwl which a wlroots wayland compositor

different wlroots compositors implement different wayland protocols
so the reason i dont have a pipewire screencapture option in obs may be because of the compositor im using

just checked with labwc
same issue no pipewire screencapture option in obs
 
start pipewire

Code: 
daemon -f pipewire

still no pipewire screen capture option in obs
 
Oh, guys. I know that this is off topic, but After installing PrismLauncher (Minecraft game launcher) and making some changes for opengl/openjdk (i forgot name..) which are recommends after installation in "Notes", I broke obs studio....

Also I tried to reinstall obs by just `pkg delete obs-studio` then `pkg install obs-studio`.
And also AMD GPU drm-kmod..

I don't use my system by root.
Also I use FreeBSD 14.1

I am trying to make "labwc" (which uses a "wlroots" compositor) capture either OBS or Firefox to share my screen/window. I've installed the following packages
Ive set them to autostart with the launch of my labwc session with:
  • pipewire &
  • /usr/local/libexec/xdg-desktop-portal -r &
  • /usr/local/libexec/xdg-desktop-portal-wlr -r &

dbus is enabled and running. I launch my labwc session with the command dbus-launch labwc. Whenever I open OBS and try to capture from Pipewire, nothing happens.

I've attached logs below.

Is there something I am missing? I've read the man page for /usr/local/libexec/xdg-desktop-portal-wlr -r and I created a basic config file which has the following lines
Code: 
# File ~/.config/xdg-desktop-portal-wlr/labwc:wlroots
[screencast]
output_name=HDMI-A-1
max_fps=30
chooser_type=simple
chooser_cmd=slurp -f %o -or

obs works for me without auto starting anything

labwc-start

Code: 
#!/bin/sh

# labwc start
exec dbus-launch --exit-with-session labwc

try installing grim

Code: 
sudo pkg install grim

see if that resolves the issue

What graphics card do you have? I have an Nvidia 2080 Super and I think that might be the culprit.

I've made a bit of progress ever since my last post. grim was already installed in my last thread and it wasn't working.

I think what fixed my main problem is that I renamed ~/.config/xdg-desktop-portal-wlr/labwc:wlroots to ~/.config/xdg-desktop-portal-wlr/config, which was another option listed on the man page. After that, screen sharing with firefox worked perfectly.

Afterwards, I noticed on the OBS logs that it was complaining something about QT. I installed qt6-wayland and that made the complains go away. Still, I cannot capture my screen with OBS. Now instead of getting the error error: Cannot query the number of formats: The last function succeeded without error. I get another error haha, I guess that is progress

The error now (to my understanding) is that a format is trying to be negotiated, then an error error: No GL_OES_EGL_image appears which starts another negotiation. Format negotiation happens for a while, until it finally stops but i get an eternal error log of error: [pipewire] buffer is corrupt. I think something is missing in encoding, but I am not to knowledge in this area.

I also notice another error as obs is loading reharding FFMPEG and Nvidia encoding, which is listed below (I also attached the full obs verbose logs for anyone interested). After this format negotiating and pipewire errors, some windows in my main screen get corrupted so I gotta restart the "labwc" session which is annoying.

I looked into this encoding package missing, it seems I have to install a pkg named "linux-nvidia-libs", but this requires the Linux emulator and other compat stuff which I rather not deal with, so I am kind of giving up for now. I might record my screen using another Wayland Utility. My main concern was getting Firefox screensharing to work.

the errors are character building
if that helps

another thing to mention

to select audio devices in the settings you have to start pulseaudio first

Code: 
pulseaudio --start --daemonize 2>/dev/null
 
I remember that I also found the pkg lib6c-shim so i decided to give it another go. I installed it and since I don't use desktop entries, I ran the "Exec" line in the desktop entry that you kindly shared.

Sadly no change, the same "pipewire buffer is corrupt" messages and the screen tearing on my main screen. Also, interestingly CUDA is not enabled. Maybe I need to restart after installing the shim package?

Ha, thanks for the pulseaudio tip. Since sound worked straight out on my desktop I didn't bother too much checking it out yet.

nv-sglrun nvidia-smi

you need to start pulseaudio so you can select the audio monitoring device in settings
to let you hear audio that is set to monitor and output

if you dont need to monitor the audio output you dont need to start pulseaudio
and you can add a oss or jack input for the mic
 
you can capture system audio using virtual oss
its also possible to capture alsa audio

its possible to use obs without running pulseaudio
( but you wont be able to monitor the audio output )

im using dwl with wlroots and wlrobs
i can capture displays but not windows

screen capture depends on which compositor you use

have you got wlrobs installed

Code: 
wlrobs-1.1_3                   Wayland screen capture plugin for obs-studio

Code: 
sudo pkg install wlrobs

OBS Studio has audio filters you can apply to your mic but they dont have any visual feedback by showing the audio waveform

You can also use VST 2 audio filters with OBS Studio but on my system the VST 2 option doesnt show up under filters

So we can use Ardour and Linux Studio Plugins to add noise removal,
