通过 Rightscripts 安装 OpenCV 和 FFMPEG 时出错

Question

我正在编写一个 RightScript 来在 linux 服务器上安装 OpenCV-2.3.1。 我正在使用 FFMPEG 包：ffmpeg-0.7-rc1

我在服务器上手动安装它时所做的一切都是一样的，但是当我尝试使用 rightscripts 启动机器时遇到了一些错误。通过 bash 手动构建时，OpenCV 可以正常安装和工作。

我得到的错误是：

我进行了谷歌搜索，我了解到一些 FFMPEG 功能现在已被弃用。我也尝试过安装最新的 FFMPEG 包，但我遇到了同样的错误。另外，我想知道为什么当我通过 bash 在服务器上手动安装时没有出现这些错误，并且只有当我使用 Rightscripts 安装时才出现这些错误。

Answer 1

如果您的发行版有，您还需要安装 ffmpeg-dev 软件包。如果没有，您可能还需要安装 libavcodec-dev、libavformat-dev 和 libswscale-dev。

如果您安装了它们，但 OpenCV 的构建仍然找不到它们，可能是因为 pkg-config 无法找到 ffmpeg 标头。此信息通常位于/usr/lib/pkgconfig，这意味着如果您的路径不同，您可能必须手动添加正确的路径。例如，如果 pkg-config 的 ffmpeg 文件位于 /usr/local/lib/pkgconfig，在再次运行 CMake 之前，您应该执行：

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

Answer 2

使用 FFMPEG 包 ffmpeg-0.8 解决了这个问题。它适用于 OpenCV-2.3.1 最近对 FFMPEG 进行了许多修复，这些修复引起了一些冲突。 ffmpeg-0.8 稳定且运行良好。

Answer 3

我不需要 ffmpeg，因为我只识别图像，所以使用此选项跳过组合视频模块：

make -DWITH_FFMPEG=OFF xxxxxx
