linux - 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

在服务器上手动安装它时，我所做的与我所做的完全一样，但是当我尝试使用正确的脚本启动机器时出现了一些错误。当通过 bash 手动构建时，OpenCV 安装和工作正常。

我得到的错误是:

我进行了谷歌搜索，我了解到一些 FFMPEG 函数现在已被弃用。我也尝试安装最新的 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它时，并且只有当我使用 Rightscripts 安装时，才不会出现这些错误。

Answer 1

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 进行了一些修复，这些修复引起了一些冲突。 ffmpeg-0.8 稳定且工作正常。
