AForge.Video.FFMPEG used in C#

I use Visual C# 2008 and want to write AVI file from bmp sequences.

I found AForge.Video.VWF but it's just for "vmw3" or "DIB " codecs and I want to use AForge.Video.FFMPEG but it got error.

For example I just code :

using System;
using System.Collections.Generic;

using System.Linq;
using System.Text;
using AForge.Video.FFMPEG;

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            VideoFileWriter vfw = new VideoFileWriter();
        }
    }
}

But I got this filenotfoundexception

{"The specified module could not be found. (Exception from HRESULT: 0x8007007E)":null}

In order to use AForge.Video.FFMPEG correctly, you have to be sure to include the FFmpeg dll's into your output folder. The easiest way is to add them into your VS project, go on their properties and set the Copy to Output Directory option to "Always".

The FFmpeg binaries used by AForge can be found on the AForge.NET's external folder, typically in C:\Program Files (x86)\AForge.NET\Framework\Externals\ffmpeg\bin
