.NET, C#, DirectX, WMV

Determine a video size and duration

You can determine the size and duration of a video using DirectX.
After installing DirectX on your development box, add a reference to Microsoft.DirectX.AudioVideoPlayback assembly.

Then, create an instance of a Video class and pass the name of the movie file you want to load (I tested it using a WMV file).


Microsoft.DirectX.AudioVideoPlayback.Video video = new Microsoft.DirectX.AudioVideoPlayback.Video(path);
StringBuilder sb = new StringBuilder();
textBox1.Text = sb.ToString();

  1. Any idea how I can implement this code in an ASP or ASPX file so all I have is a function where I specify the file path and all I get is the video duration? Thanks 🙂

  2. the code don’t runs ASP.NET boys

    using Microsoft.DirectX.AudioVideoPlayback;

    Video vvideo = new Video(video.f_VideoAdiGetir(fuVideo.FileName.ToString()));
    StringBuilder sb = new StringBuilder();
    error message;

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

    “vvideo” instance is created error msj ://
