  Using FFMPEG Wmv to Swf: Not Working in C#: Need Help...

  Oct 06, 2008 08:00 AM|LINK

  Hai all,

  In my application i am trying to convert my wmv file into swf file format. And its working on Command prombt very well and it created the output file also.

  But when i write the code in c# (below mentioned) its not working. But no more errors or exceptions arise. But No outputs found(no new.swf file was created).

   

  filargs = "ffmpeg -i d:\\hai.wmv -s 480*360 -deinterlace -ab 32 -r 15 -ar 22050 -ac 1 d:\\hai.swf";

  System.Diagnostics.Process proc = new System.Diagnostics.Process();proc.StartInfo.FileName ="D:\\ffmpeg\\ffmpeg.exe";

  proc.StartInfo.Arguments = filargs;

  proc.StartInfo.UseShellExecute = false;

  proc.StartInfo.CreateNoWindow = false;proc.StartInfo.RedirectStandardOutput = false;

  proc.Start();

  proc.WaitforExit(50000);

   

   

  Thanks in Advance...

  Sham

  I've falled into this trap before...

  proc.StartInfo.RedirectStandardOutput = false;

  ...Try redirecting StandardError too

  thanks for reply,

  proc.StartInfo.RedirectStandardError = false;

  proc.Start();

  StreamReader standardError = proc.StandardError;

  proc.WaitForExit();

  lblmsg.Text = standardError.ReadToEnd()

   

  I am getting the error displayed on my label(lblmsg) -  "StandardIn has not been redirected "

  See my post here. The code I used worked after I redirected standard error:

  This is an error with your console app:

  gcc: 4.2.3 Unable to find a suitable output format for 'ffmpeg' 

   Try debugging at the command prompt

  Hi,

  I have written below code, and it wont produce the result(convert into .swf) when i upload .wmv file. But it is working in command prombt.

  So please check and give solution for me..... 

  And if you dont mine why you are using (C:\\dbping) 

   

   

  postedfilename = FileUpload1.PostedFile.FileName;

  SavePath = AppDomain.CurrentDomain.BaseDirectory + "Video\\";

  string NewFName = postedfilename;

  NewFName = NewFName.Substring(NewFName.LastIndexOf("\\") + 1, NewFName.Length - NewFName.LastIndexOf(".")) + "." + NewFName.Substring(NewFName.LastIndexOf(".") + 1);

  Filenamewithpath = SavePath + NewFName;

  //Save The file

  FileUpload1.PostedFile.SaveAs(Filenamewithpath);

  //Start Converting

  string inputfile, outputfile, filargs,dbfilename;

  string withoutext;

  //Get the file name without Extension

  withoutext = Path.GetFileNameWithoutExtension(Filenamewithpath);

  //Input file path of uploaded image

  inputfile = SavePath + NewFName;

   

  //output file format in swf

  outputfile = SavePath + "SWF\\" + withoutext+ ".swf";

  dbfilename = withoutext + ".swf";

  //outputfile = "D:\\hai.swf";

  //file orguments for FFMEPG

  filargs = "-i \""+ inputfile +"\" -s 480*360 -deinterlace -ab 32 -r 15 -ar 22050 -ac 1 \""+outputfile +"\"";

  string spath;

  //spath = Server.MapPath(".");

  spath = AppDomain.CurrentDomain.BaseDirectory;

  DirectoryInfo directoryInfo = new DirectoryInfo(Path.GetDirectoryName(Server.MapPath("ffmpeg")));

  System.Diagnostics.ProcessStartInfo psi = new ProcessStartInfo("C:\\dbping");

  psi.WorkingDirectory = "C:\\";

  psi.ErrorDialog = false;

  psi.RedirectStandardOutput = true;

  psi.RedirectStandardInput = true;

  psi.RedirectStandardError = true;

  psi.UseShellExecute = false;

  psi.CreateNoWindow = true;

  System.Diagnostics.Process proc = new System.Diagnostics.Process();

  proc.StartInfo = psi;

  proc.StartInfo.FileName = spath + "ffmpeg\\ffmpeg.exe";

  proc.StartInfo.Arguments = filargs;

  proc.StartInfo.UseShellExecute = false;

  try

  {

  proc.Start();

  StreamWriter standardInput = proc.StandardInput;StreamReader standardError = proc.StandardError;

  proc.WaitForExit();

  //lblmsg.Text = standardError.ReadToEnd();

  }

  catch (Exception ex)

  {

  Response.Write(ex.Message);

  }

  proc.Close();

   

   

   

  Thanks and Regards
