This is not about a window. There is no window involved here. It's the 
"offscreen" rendering callback for OpenGL. It renders to whatever the 
host app chooses in libvlc.

And in fact I can see how this code was even originally designed to 
handle failure:

if(sys->width==w&&sys->height==h)

return;

if(!sys->resizeCb)

return;

MakeCurrent(gl);

sys->resizeCb(sys->opaque,w,h);

ReleaseCurrent(gl);

sys->width=w;

sys->height=h;
