我已经安装了 OBS Studio 的 snap 版本，并按照此网页上的说明进行操作：https://snapcraft.io/obs-studio
我想使用虚拟摄像头选项来模糊其他应用程序（如 Zoom/MS Teams 等）中的背景。（我还喜欢使用欢迎屏幕等进行更专业的演示的想法。）
第一次安装v4l2loopback-dkms出现错误：
dkms can't load "/var/lib/shim-signed/mok/.rnd" into rng
移除并再次安装后，安装没有问题。
snap connections obs-studio似乎表明连接良好。

OBS Studio 启动正常，但是我没有看到网络摄像头作为源，也没有在菜单中看到使用虚拟摄像头的选项tools。
当我在终端启动 OBS Studio 时，我确实收到两个错误：
info: [Move Transition] loaded version 2.4.3
error: os_dlopen(libnvidia-fbc.so.1->libnvidia-fbc.so.1): libnvidia-fbc.so.1: cannot open shared object file: No such file or directory

不知道这是否与此有关。
任何关于如何解决这个问题的想法都将不胜感激，因为我没有主意了。:)

我刚刚安装了 deb 包版本，它做接收网络摄像头和虚拟摄像头的输出。
