我最近在网上买了一个最便宜的红外摄像头。它在我的 Windows 机器上运行良好，但我无法让它在我的 Ubuntu 18.10 上运行。你能帮忙吗？
我已经尝试过的：
打开 Cheese 显示“未找到设备”
打开 VLC，转到媒体 > 打开捕获设备并尝试使用
/dev/video0或/dev/video1（我不知道为什么在连接相机时会出现其中 2 个）说：无法打开您的输入：VLC 无法打开 MRL“v4l2:///dev/video0”。请查看日志了解详细信息。”
以下是日志：

答案1
我打开了 synaptic（我建议安装它）并查找了 VLC 扩展。起初我以为我必须安装 vlc-plugin-zvbi，但它不可用，至少在 20.04 中不可用。
我使用以下命令使其工作： sudo apt install vlc-plugin-access-extra vlc-plugin-base vlc-plugin-qt vlc-plugin-video-output vlc-plugin-video-splitter vlc-plugin-visualization
公平地说，我没有检查它是否适用于较少的软件包。我只是点击了所有多媒体选项。
