  25 mai 2020, par Hamad

  I want to get the video file duration in string using C#. I searched the internet and all i get is :

  



  ffmpeg -i inputfile.avi


  



  And every1 say that parse the output for duration.

  



  Here is my code which is

  



  string filargs = "-y -i " + inputavi + " -ar 22050 " + outputflv;
    Process proc;
    proc = new Process();
    proc.StartInfo.FileName = spath;
    proc.StartInfo.Arguments = filargs;
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.CreateNoWindow = false;
    proc.StartInfo.RedirectStandardOutput = false;
    try
    {
        proc.Start();

    }
    catch (Exception ex)
    {
        Response.Write(ex.Message);
    }

    try
    {
        proc.WaitForExit(50 * 1000);
    }
    catch (Exception ex)
    { }
    finally
    {
        proc.Close();
    }


  



  Now please tell me how can i save the output string and parse it for the video duration.
