C# wrapper for FFMPEG

We are looking to have a C# wrapper class created that wraps three very simple methods from the FFMPEG open source api. If you are not familiar with FFMPEG, you can read more about it here.

In addition, we want complete instructions on what we need to download/install FFMPEG onto our server to work with your new c# class. In addition, please provide a simple test app that shows the use of the three methods. This could be a simple C# console app.
