Thanks for this, it's great. The example works as it is, then I switched 
it from avsamplebufferlayersink to caopengllayersink and it worked the 
same, then I put a smaller view within the window and put the layer 
there, still fine. So then I incorporated it into my wxWidgets app, 
using caopengllayersink:
    CALayer *layer;
    g_object_get(m_videosink, "layer", &layer, NULL);
    NSView *nsv = GetPeer()->GetWXWidget();
    [nsv setWantsLayer:YES];
    [nsv setLayer:layer];
and it works! Fantastic, thank you. Possibly the documentation for 
GstVideoOverlay should indicate that that's not really the way to do it 
on Mac these days.

I did look briefly at this but it wouldn't compile - various problems - 
and the copyright message in the file is 2009 so maybe it needs
updating (or dumping).
