I am giving code for Convert into .Flv But it is not in Javascript The method to convert video to .flv is too easy. 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
