Hi Pierre;

Is this "-l minimal_macosx" a command-line parameter to VLC?
What do you mean by "pass an object"?  I don't understand what object  
you mean and where I pass it.

I did remove the "macosx" module, and add "-l minimal_macosx" to the  
command line.  The debugger shows that minimal_macosx is definitely  
being loaded and used, but I still don't see any video in my app.
