gnome的话大概率是wayland环境吧?obs在wayland下需要依赖pipewire做屏幕采集,你检查一下是不是有什么pw相关的包没安装
https://wiki.archlinux.org/title/PipeWi … en_sharing参考这段wiki,主要检查一下你是否安装了xdg-desktop-portal 和xdg-desktop-portal-gnome这两个包
安装了软件包之后重启xdg-desktop-portal.service这个系统服务应该就可以立即生效了

2个包都装过了,但是.service不在默认的 /lib/systemd/system目录,复制一份过去后,执行 systemctl restart xdg-desktop-portal.service 后,报如下错误

不是你这么搞的,怪我之前没说清楚,
xdg-desktop-portal.service是一个user service(用户级别的服务)所以启用的时候要用
systemctl --user start xdg-desktop-portal
systemctl --user start xdg-desktop-portal-gnome
你把/lib/systemd/system目录下面自己手动复制过去的service删掉吧,然后再用上面两条命令试试

你说的东西和楼主的问题不是一回事,楼主要解决最原始的屏幕录制问题,也就是目前wayland下面屏幕录制的解决方案——通过pipewire的实现抓屏
你提到的内容都是解决特定软件不支持wayland现有屏幕录制方案的问题,
用v4l2虚拟相机也要先抓到屏幕内容(也就是上面提到的pipewire方法)然后放进去,然后让想用的软件从v4l2虚拟相机中拿图像。。

你有使用pipewire-media-session或者wireplumber吗?
pipewire录屏需要上面中的一个(他们本身也是互相替代的关系)

yay 搜了下,只装了pipewire,只要装了pipewire-media-session 这个包就可以了吗?

要启用,虽然默认自动启用,但是也有例外情况,你最好确认一下,另外,pipewire-media-session会接管你的audio 服务,如果你之前使用的PulseAudio可能会冲突,要注意处理

pipewire 采集屏幕也是黑的?看一下 gst-plugins-good 和 gst-plugin-pipewire 有没有安装
另外说一句题外话,是不是nvidia显卡?
