 |
|
Hi, I am trying to make pipewire work on my gentoo installation with wayland, but unfortunately it doesn't see any devices. I am not very interested in using 'pipewire' as an audio server, I want to use it at least for enabling screen recoding in OBS studio. I've enabled 'pipewire' and 'screencast' use flags, installed 'pipewire' and 'wireplumber':
| Code: |
pipewire
Compiled with libpipewire 0.3.80
Linked with libpipewire 0.3.80
wireplumber
Compiled with libwireplumber 0.4.14
Linked with libwireplumber 0.4.14
|
I've added myself to the 'pipewire' group according to the documentation. Copied configuration files from '/usr/share/pipewire/pipewire.conf' to '/etc/pipewire/pipewire.conf' and '~/.config/pipewire/pipewire.conf'. I am starting the wireplumber and pipewire with the following command:
| Code: |
gentoo-pipewire-launcher
|
Then I run 'wpctl status', which displays no devices:
| Code: |
PipeWire 'pipewire-0' [0.3.80, cait@gen2, cookie:3468668857]
└─ Clients:
32. WirePlumber [0.3.80, cait@gen2, pid:9475]
33. WirePlumber [export] [0.3.80, cait@gen2, pid:9475]
36. wpctl [0.3.80, cait@gen2, pid:13588]

When I run 'pw-top' it displays two processes - 'Dummy-Driver' and 'Freewheel-Driver'.
My use flags for 'pipewire':

- - roc : Enable roc support for real-time audio streaming over the network, using
media-libs/roc-toolkit. See
https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Network#roc
- - sound-server : Provide sound server using ALSA and bluetooth devices
+ + ssl : Enable raop-sink support (needs dev-libs/openssl)
- - systemd : Enable use of systemd-specific libraries and features like socket activation or session
tracking

FEATURES=test but can be toggled independently)

- - zeroconf : Support for DNS Service Discovery (DNS-SD)
|
And for 'wireplumber':
| Code: |
U I
+ + elogind : Enable session tracking via sys-auth/elogind
- - lua_single_target_lua5-3 : Build for Lua 5.3 only
+ + lua_single_target_lua5-4 : Build for Lua 5.4 only
- - systemd : Enable use of systemd-specific libraries and features like socket activation
or session tracking
- - test : Enable dependencies and/or preparations necessary to run tests (usually
controlled by FEATURES=test but can be toggled independently)

UPDATE: It seems that it is a normal behavior that no devices are listed when running 'wpctl status'.
I've moved 'wireplumber' launcher to 'hyprland.conf' like this:
| Code: |
exec-once = dbus-update-activation-environment & /home/cait/.config/hypr/xdg-portal-hyprland.sh & gentoo-pipewire-launcher & waybar
|
and tested OBS studio on on 'gnome' instead of 'hyprland'. On 'gnome' it works perfectly - I launch OBS studio and there is an option to choose either screen capture either window capture through pipewire. Here is the fragment from OBS studio logs:
| Code: |
info: [pipewire] Available captures:
info: [pipewire] - Desktop capture
info: [pipewire] - Window capture
|
Now when I run 'hyprland' there are same messages in logs saying that 'pipewire' now detects my screen. However, after I add screen capture to scene, the following message starts to be printed into log repeatedly:
| Code: |
info: [pipewire] Negotiated format:
info: [pipewire] Format: 8 (Spa:Enum:VideoFormat:BGRx)
info: [pipewire] Modifier: 0x0
info: [pipewire] Size: 669x741
info: [pipewire] Framerate: 0/1
|
And the screen is black, so screen recording still doesn't work. Can anybody help me please figure out what I am doing wrong |
