set VLC player options

Question

I have C# code to play video in VLC player , I want to set video option while adding URL to play. My code is as below.

AxAXVLC.AxVLCPlugin2 axVLCPlugin21;
 axVLCPlugin21.playlist.add(<some video URL>, null, null);
 axVLCPlugin21.playlist.play();

In above line i want to set video output module option as Directx (DirectDraw) video output option. Is there any way we can set this option while we add url to playlist ? If yes how we can do the same.

In actual VLC player this option can be find in Tools -->Preferences --> Show setting Radio checked All --> select Video output moduleenter image description heres --> it has drop down with choices.

I tried with setting var options = ":demux=rawaud :rawaud-channels=2 :rawaud-samplerate=44100 :rawaud-fourcc=s16b"; and passed this to playlist.add method as argument.

but it did not worked
