在 CentOS 7 上编译 Shotdetect

Question

我正在将一项服务从 Debian 服务器迁移到 CentOS 7 服务器。

该服务需要 Shotdetect 命令（github , official site）。

尽管我遵循了所有步骤，但我无法在 CentOS 上运行它：

安装需要的包

# yum install gd-devel libxml2-devel libxslt-devel clang libvpx libvorbis

在 CMakeList 文件中添加 pthread，在 TARGET_LINK_LIBRARIES 中，因为它抛出一个 lpthread missing in linker错误

编译Shotdetect

# FFMPEG_DIR="/root/ffmpeg_build"  ./compile.sh cmd

我对上述错误进行了大量研究，但没有找到任何线索。

如何在CentOS7上编译成功Shotdetect？

你检查过这个类似的问题吗？ Linking libavcodec and libavformat: Undefined references

他们建议添加一些库：

-lswresample -lm -lz
