我们正在尝试在RH Linux服务器上安装ffmpeg。
麻烦的是，它不是在另一个上工作，我们不知道为什么。工作和非工作服务器具有相同的配置信息：

我想问一下这是否与问题有关。在我试图找出libz.so如何出现在一个列表而不是另一个列表之前。
btw ld.so.conf文件是相同的。
答案 0 :(得分：0)
一个版本没有引用zlib而另一个版本没有引用zlib有点不寻常。但是，除非您使用依赖于zlib的格式（多个容器和编解码器），否则这不会导致问题。不是在这种情况下。
错误文本中列出了具体问题：
[libvpx @ 0x314ab40] v0.9.6
[libvpx @ 0x314ab40] Failed to initialize encoder: ABI version mismatch
FFmpeg和libvpx没有相处。
看起来你自己从最新的源代码编译了FFmpeg。 libvpx来自哪里？从Red Hat RPM安装？或编译自己？您是否在其中一个RH框上编译，然后将二进制文件移动到另一个？
