请注意，pyvirtualcam依赖于创建实际虚拟摄像机设备的本机库。您可能需要为此安装其他软件，具体取决于您的操作系统：
在Windows上，您需要OBS VirtualCam 2.0.4或更高版本。您可以从OBS项目网站下载它。在macOS上，你需要CamTwist。你可以从CamTwist网站下载。在Linux上，您需要v4 l2 loopback。你可以从你的包管理器中安装它，例如，在Ubuntu上使用sudo apt install v4 l2 loopback-dkms。在运行脚本之前，您还需要使用sudo modprobe v4 l2 loopback加载模块。要使此更改永久化，可以将v4 l2 loopback添加到/etc/modules。
