I think it should work as is. But I might be wrong, if so just  
provide a drawable to mediacontrol.

ins = mediacontrol_new( argc, argv, &ex );
But I am sure that you want to pass directly argv[0] as a libvlc arg.

I suggest you to look at the Mac OS X Framework code as an entry point:
http://git.videolan.org/cgi-bin/gitweb.cgi?p=vlc- 
soc.git;a=blob;f=extras/MacOSX/Framework/Sources/ 
VLCVideoView.m;hb=56dbdfccb979105d87f20ba60002c8b778590b40
