Is Vlc.DotNet able to do this?

To answer this question, please first answer the question "Is VLC able to do this?". If no, then I'm sorry for you. Maybe you could ask the VLC developers if they want to support that feature, or even better, submit a patch for them.

Yes? alright. Then you should probably be able to do this with Vlc.DotNet (no warranty implied though). One more question : How do you do this when starting vlc from command line?

Once you have found the answer to this question, then you should be able to pass the correct options to Vlc.DotNet.
