我的笔记本电脑配备了英特尔实感 F200 网络摄像头，该摄像头在 Fedora 上无法正常工作，当我启动网络摄像头时，输出图像是绿色的，并带有我的剪影。我在网上搜索并找到了这个图书馆https://github.com/IntelRealSense/librealsense但由于安装指南是针对 Ubuntu 的，所以我不知所措。
有一个脚本（patch-uvcvideo-fc23.sh）可以安装一些依赖项并加载 uvcvideo 模块。但即使之后网络摄像头仍然是绿色的。的输出sudo dmesg | tail -n 50是

有没有办法让网络摄像头在这个系统上工作？
答案1
不是一个解决方案，但也许这对某人有帮助。 Fedora 25 还需要以下内容才能正确编译：
dnf install numactl-devel pesign
videodev2.h 的补丁失败。打开文件 realsense-camera-formats.path，从第 152 行删除到文件末尾，添加以下内容并保存文件：

现在转到 librealsense 文件夹并运行scripts/patch-uvcvideo-fc23.sh（不要在脚本文件夹中运行脚本，转到上一个目录）。
您不需要以 root 身份运行该脚本，它将根据需要使用 sudo（您的用户将需要使用 sudo）。现在应该可以编译了。奶酪对我来说仍然显示为绿色，但 xawtv 可以工作。
