You can download f ollowing files from .net 1)ffmpeg.exe 2) ffplay.exe 3) pthreadGC2.dll After downloading all the files Follow these steps written:- 1)Make a new .net web site or windows application . 2)Copy and paste all the 3 above written files to root location 3)Copy and Paste code written below 4)Put an upload to page and rename to  fileuploadImageVideo 5)put and button and rename to btn_Submit 6)Make 3 folders OriginalVideo ConvertVideo Thumbs 7)Import Class using System.IO; 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 Convert Video Folder
