You need some sort of signal from VLC to provide information, then match that information to a game category in some program or plugin to VLC, which then makes the relevant API call to Twitch.
So you need a developer for this. Even if VLC can provide information you can match to a game category on Twitch (as you need the Category/Game ID not just the title of the game), assuming you want to update both the title and the game/category of the stream as needed.
