I'll note you still didn't say what "this didn't work" means, but I can guess. > 2016-09-06 17:12:50.963 Hollywood[1160:23595] Unable to simultaneously > satisfy constraints: > ( > "<NSLayoutConstraint:0x1005ca210 H:|-(10)-[NSView:0x1005c58d0] (Names: > '|':AVExternalPlaybackIndicatorView:0x1005c5160 )>", > "<NSLayoutConstraint:0x1005ca280 H:[NSView:0x1005c58d0]-(10)-| (Names: > '|':AVExternalPlaybackIndicatorView:0x1005c5160 )>", > "<NSLayoutConstraint:0x1005ca150 NSView:0x1005c5c80.centerX == > NSView:0x1005c58d0.centerX>", > "<NSLayoutConstraint:0x1005ca620 H:|-(0)-[NSView:0x1005c5c80] (Names: > '|':NSView:0x1005c58d0 )>", > "<NSLayoutConstraint:0x1005ca4e0 AVDraggableImageView:0x1005c6030.centerX == > NSView:0x1005c5c80.centerX>", > "<NSLayoutConstraint:0x1005ca900 H:|-(>=0)-[AVDraggableImageView:0x1005c6030] > (Names: '|':NSView:0x1005c5c80 )>", > "<NSLayoutConstraint:0x100568020 > H:|-(0)-[AVExternalPlaybackIndicatorView:0x1005c5160] (Names: > '|':MyAVPlayerView:0x1004f5b70 )>", > "<NSLayoutConstraint:0x1005cbce0 > H:[AVExternalPlaybackIndicatorView:0x1005c5160]-(0)-| (Names: > '|':MyAVPlayerView:0x1004f5b70 )>", > "<NSAutoresizingMaskLayoutConstraint:0x1086c3130 h=--& v=--& > H:[MyAVPlayerView:0x1004f5b70(0)]>", > "<NSLayoutConstraint:0x1005cad30 V:[AVDraggableImageView:0x1005c6030(>=43)]>", > "<NSLayoutConstraint:0x1005cace0 AVDraggableImageView:0x1005c6030.width == > 1.45556*AVDraggableImageView:0x1005c6030.height + 1>" > ) > > Will attempt to recover by breaking constraint > <NSLayoutConstraint:0x1005ca150 NSView:0x1005c5c80.centerX == > NSView:0x1005c58d0.centerX> > > Set the NSUserDefault > NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have > -[NSWindow visualizeConstraints:] automatically called when this happens. > And/or, break on objc_exception_throw to catch this in the debugger. These are errors from the autolayout system. I'm not sure if you're using autolayout in the rest of your view hierarchy, but it appears that AVPlayerView uses it internally. That's potentially fine, except that it requires that the player view be at least 63 points wide. There may also be height constraints.
