嗨，Ubuntu 爱好者们，
我已经编译并加载了下面 github 上的内核驱动程序模块“gspca-kinect2”，因为我希望我的 kinect 2 被检测为 skype 的网络摄像头，但它没有工作。我发出的命令解释如下：
https://github.com/tduck973564/gspca-kinect2
回顾一下：
wget -q -O - https://raw.githubusercontent.com/tduck973564/gspca-kinect2/master/install-webcam.sh | sudo sh
$ make -C /lib/modules/`uname -r`/build M=`pwd` SRCROOT=`pwd` clean modules
$ sudo /sbin/rmmod gspca_main
$ sudo /sbin/modprobe videodev
$ sudo /sbin/insmod ./gspca_main.ko
$ sudo /sbin/insmod ./gspca_kinect2.ko
$ ffmpeg -framerate 30 -video_size 640x480 -i /dev/video1 test.avi
$ mplayer test.avi
并且它成功了（这意味着它能够捕捉到我房间里的东西，并将其保存在可以重现的 avi 文件中：

当我尝试将设备 /dev/video1 用于 skype 和 zoom 时，出现了问题。事实上，由于某些未知原因，他们无法正确检测 kinect 2，我只看到黑屏，而看不到我的脸。下面您可以看到他们检测到的设备是什么（它们 = skype for web + chrome 浏览器和 zoom；相反，ubuntu 上的 skype 客户端只检测到位于 0000:0000 的虚拟设备）：
我的 ubuntu 21.10 上的 kinect 2 位于以下地址：
