How use asp.net get video duration

Question

using Microsoft.DirectX.AudioVideoPlayback;

Video vvideo = new Video(FileUpload.FileName.ToString());
StringBuilder sb = new StringBuilder();
sb.Append(duration.toString());
error message;

“Installed an access attempt was made to the application domain.”

“vvideo” instance is created error msj ://

But down found cods I found a working code in c #. but asp.net does not work

string file1 = "c://ds.mpeg"
IMediaPosition m_objMediaPosition = null;
FilgraphManager m_objFilterGraph = new FilgraphManager();
m_objFilterGraph.RenderFile(filename);
m_objMediaPosition = m_objFilterGraph as IMediaPosition;

int s = (int)m_objMediaPosition.Duration;
int h = s / 3600;
int m = (s - (h * 3600)) / 60;
s = s - (h * 3600 + m * 60);

I DON'T TAKE VIDEO DURATION BOYS :/

Answer 1

I make Function everywhere it uses ;)

public string f_VideoDuration((add path)parameters)
{

    try
    {
        string sInputVideo = Page.MapPath(add path);
        string sPath = " -i " + sInputVideo ;

        Process ffmepg = new Process();
        ffmepg.StartInfo.FileName = (Server.MapPath("ffmpeg.exe"));
        ffmepg.StartInfo.UseShellExecute = false;
        ffmepg.StartInfo.RedirectStandardOutput = true;
        ffmepg.StartInfo.RedirectStandardError = true;
        ffmepg.StartInfo.CreateNoWindow = true;
        ffmepg.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        ffmepg.StartInfo.Arguments = sPath;
        ffmepg.EnableRaisingEvents = true;
        ffmepg.Start();
        string sDuration = ffmepg.StandardError.ReadToEnd().ToString();
        ffmepg.Close();
        ffmepg.Dispose();

        sDuration = sDuration.Remove(0, sDuration.LastIndexOf("Duration: ") + 10);
        sDuration = sDuration.Substring(0, sDuration.IndexOf(","));
        return sDuration;
    }
    catch (Exception ex)
    {
        throw (ex);
    }
}
