private bool ReturnVideo(string fileName)
{
string html = string.Empty;
//rename if file already exists

int j = 0;
string AppPath;
string inputPath;
string outputPath;
string imgpath;
AppPath = Request.PhysicalApplicationPath;
//Get the application path
inputPath = AppPath + "OriginalVideo";
//Path of the original file
outputPath = AppPath + "ConvertVideo";
//Path of the converted file
imgpath = AppPath + "Thumbs";
//Path of the preview file
string filepath = Server.MapPath("~/OriginalVideo/" + fileName);
while (File.Exists(filepath))
{
j = j + 1;
int dotPos = fileName.LastIndexOf(".");
string namewithoutext = fileName.Substring(0, dotPos);
string ext = fileName.Substring(dotPos + 1);
fileName = namewithoutext + j + "." + ext;
filepath = Server.MapPath("~/OriginalVideo/" + fileName);
}
try
{
this.fileuploadImageVideo.SaveAs(filepath);
}
catch
{
return false;
}
string outPutFile;
outPutFile = "~/OriginalVideo/" + fileName;
int i = this.fileuploadImageVideo.PostedFile.ContentLength;
System.IO.FileInfo a = new System.IO.FileInfo(Server.MapPath(outPutFile));
while (a.Exists == false)
{

}
long b = a.Length;
while (i != b)
{

}


string cmd = " -i \"" + inputPath + "\\" + fileName + "\" \"" + outputPath + "\\" + fileName.Remove(fileName.IndexOf(".")) + ".flv" + "\"";
ConvertNow(cmd);
string imgargs = " -i \"" + outputPath + "\\" + fileName.Remove(fileName.IndexOf(".")) + ".flv" + "\" -f image2 -ss 1 -vframes 1 -s 280x200 -an \"" + imgpath + "\\" + fileName.Remove(fileName.IndexOf(".")) + ".jpg" + "\"";
ConvertNow(imgargs);


return true;
}
private void ConvertNow(string cmd)
{
string exepath;
string AppPath = Request.PhysicalApplicationPath;
//Get the application path
exepath = AppPath + "ffmpeg.exe";
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = exepath;
//Path of exe that will be executed, only for "filebuffer" it will be "flvtool2.exe"
proc.StartInfo.Arguments = cmd;
//The command which will be executed
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.RedirectStandardOutput = false;
proc.Start();

while (proc.HasExited == false)
{

}
}
protected void btn_Submit_Click(object sender, EventArgs e)
{
ReturnVideo(this.fileuploadImageVideo.FileName.ToString());
}


Now run the application select a video file, that will get converted and come to ConvertVideo Folder
