So from this I assume that I need to manually start a cocoa main loop for the plugin to do its work - or is this as a LibVLC plugin developer outside of my scope?

Furthermore - from another perspective: if I start qtcapture:// via the GUI or terminal and press play (the non-automatic way) the plugin doesn't get stuck. Would it help to look into those steps source code wise? if yes - where would I have to look?
