Debian 8 最新更新后，网络摄像头不再工作。特别是奶酪显示“播放网络摄像头视频时出错”。然后我尝试使用 sudo 运行它，它显示另一条错误消息：“缺少一个或多个所需的 gstreamer 元素：cluttervideosink”然后我在网上搜索，发现了这一点：
这建议安装 gstreamer1.0-clutter 并删除文件夹 gstreamer-1.0
但是当我尝试实现该解决方案时，它只工作了一瞬间，因为该文件夹立即重新创建！
如何解决这个问题？我怀疑这是一个过时的解决方案。
我认为奇怪的事情如下：
dmesg less | grep video
很长而且很混乱，我可以发布其中的一部分：

另一个可能有用的输出是这样的，这就是当我在没有 sudo 的情况下从终端运行 Cheese 时发生的情况：

编辑：正如评论中所要求的那样
sudo apt-get -f install 的输出
