我正在使用源代码编译 FFMPEGUbuntu 指南我之前已经成功使用过。
我正在 Ubuntu 服务器 14.04 上的 VirtualBox 中的 Vagrant 虚拟机上进行编译。您可以克隆项目 和vagrant up，并且您将在框中安装 FFMPEG：github.com/rfkrocktk/vagrant-ffmpeg。
我正在使用 Ansible 来自动编译，因此您可以看到所有步骤这里:

希望即使您不了解 Ansible，也应该清楚它在做什么。
我遇到的问题是，即使所有这些都成功运行之后，当我ffmpeg从机器内部运行时，我会收到以下错误：
ffmpeg: error while loading shared libraries: libx265.so.77: cannot open shared object file: No such file or directory
我可以清楚地找到该文件：
$ find /usr -iname libx265.so.77
/usr/local/lib/libx265.so.77
为什么没有找到这个？我在编译指南中遗漏了什么吗？我希望我的二进制文件尽可能便于携带。

LD_LIBRARY_PATH环境变量中未定义。
还有这个：
$ grep -r local /etc/ld.so.conf.d/
/etc/ld.so.conf.d/libc.conf:/usr/local/lib
我的工作理论是，由于 Ansiblecommand模块删除了环境变量，所以一切都会崩溃。
我认为 FFMPEG 或 x265 构建有问题。我--enable-libx265从 FFMPEG 配置命令中删除了，现在我有了一个可以工作的 FFMPEG。
答案1
我的问题在于安装完所有东西后我从未运行过ldconfig。
为了在 Debian 上找到共享对象库，您必须运行sudo ldconfig以重建共享库缓存。
