我在Ubuntu的pyffmpeg安装失败。
Cython安装似乎是正确的：
$ sudo python setup.py install ... Adding Cython 0.22.1 to easy-install.pth file Installing cython script to /usr/local/bin Installing cygdb script to /usr/local/bin Installing cythonize script to /usr/local/bin Installed /usr/local/lib/python2.7/dist-packages/Cython-0.22.1-py2.7-linux-x86_64.egg Processing dependencies for Cython==0.22.1 Finished processing dependencies for Cython==0.22.1
我的ffmpeg在：
/usr/bin/ffmpeg
所以，我相应地改变了pyffmpeg的setup.py 。
但是，试图安装pyffmpeg会产生这些Cython错误：

我可以改变什么来安装pyffmpeg ？
要求ffmpeg的path是用于图书馆，而不是二进制文件。 在这方面应该更清楚一点，但它显示“不是目录”的事实是帮助解决特定错误的事实。
而且，与ffmpeg库相比，这看起来已经过时了，并且可能不适用于自述文件中提到的新版本。
