我一直试图在 Python 2.7 中安装 pyffmpeg 失败。我找到了一个 Python 2.6 的包，但我无法让它工作。所以，我一直在考虑 2.7。我在这个网站上看过其他人以前的帖子，但他们没有帮助。有人对这个有经验么。最终，我想开发一个转换视频格式的 wxPython 应用程序。谢谢
我最终编写的代码对我有用(非常简陋，但它有效....):

请您参考如下方法:
由于这没有正确的答案，我想形成一个。不幸的是 pyffmpeg 包装器无法执行视频编码。因此，作为一种解决方案，我建议您使用一些替代的 python 包装器，它们能够满足我们对视频的编码需求。
除此之外，您还可以使用 python
subprocess 使用完整的 FFmpeg 功能。模块来执行完整的 FFmpeg 命令。如果需要，您还可以创建自己的包装器。
Here Zulko 描述了一种使用
subprocess 的好方法与 FFmpeg。有时您会遇到一些令人困惑的事件，例如
this使用
subprocess 时.但总有解决办法!
希望这对使用 pyffmpeg 对视频进行编码有同样问题的人有所帮助!
