I'm working on small home project for video broadcasting. I've found some example and used it LibVlc.cs. I've found some example Example, but it does not works, because needed old version of library 0.8.6. So I found it, but I have exceptions on unmanaged code when I've tried to get components from API. So maybe somebody works with VLC for videobrodcasting I would like if you are Advise any examples.
In main form I've done this:

private void btnStart_Click(object sender, EventArgs e)
      {
          try
          {
              LibVlc vlc = new LibVlc();
              vlc.Initialize();
              vlc.VideoOutput = pictureBox1;
              vlc.PlaylistClear();
              string[] Options = { ":sout=#duplicate{dst=display,dst=std {access=udp,mux=ts,dst=224.100.0.1:1234}}" };
              vlc.AddTarget(@"d:\sample.avi", Options);
              vlc.Play();
          }
          catch (Exception e1)
          {
              MessageBox.Show($"Error!!! {e}");
          }
      }
