Using ffmpeg with Python 2.7 - ffmpeg

Question

I have been trying to install pyffmpeg in Python 2.7 unsuccessfully. I found a package for Python 2.6, but I can't get it to work. So, I have been mulling around with 2.7. I've seen previous post from others on this site, but they have not helped. Does anyone have experience with this. Ultimately, I want to develop an wxPython app that converts video formats. Thanks
Code that I ultimately wrote that worked for me (very rudimentary, but it works ....):

Answer 1

Since this has no proper answer, I'd like to form one. Unfortunately pyffmpeg wrapper was not able to perform video encoding. So as a solution I suggest you some alternative python wrappers which is capable of our need to encode the videos.
Python Video Converter
FFmpegWrapper
FFVideo
Apart from these you can use full FFmpeg functionality by using python subprocess module to execute full FFmpeg commands. Also with that you can create your own wrapper if you need to. Here Zulko describes a nice way of using subprocess with FFmpeg. Sometimes you will get some confusing events like this when using subprocess. But always there is a solution!
Hope this helps some one with same problem using pyffmpeg to encode videos!
