把OpenCV下ffmpeg中所有的文件拷贝到python27下，在我电脑下ffmpeg的目录D:\IDE\opencv\sources\3rdparty\ffmpeg，python27的目录为D:\IDE\Python27.
最后，因为我用的是opencv2.4.13，且python是64位的，所以我需要把opencv_ffmpeg_64.dll修改为opencv_ffmpeg2413_64.dll然后就搞定了。如果是python是32位的话，应该要修改opencv_ffmpeg.dll为opencv_ffmpeg版本号.dll即可。

else:print "Open False"可以使用了:
