I'm using VLCKit to play movies in a cocoa app, that all works fine, but now I've been trying to get a NSView to be displayed on top of the VLCVideoView, a bit like a play/pause controller.

The problem I'm having is that either the overlay view disappears underneath the VLCVideoView (when I add both as subviews to the same parent view), or the overlay will show, but the VLCVideoView stays black (when I make the overlay a subview of VLCVideoView).

Does anyone have any ideas?

Thanks

ok, I've been going over just about every bit of the framework source, but I just don't understand that even if I init the VLCMediaPlayer with a layer (initWithVideoLayer) it still calls

Code: Select all

	
addVoutSubview:(NSView *)aView

instead of

Code: Select all

	
addVoutLayer:(CALayer *)voutLayer

I guess once I can get a CALayer with the video, it'll work like any other CALayer but I just can't get to that stage.
Is this a bug or am I just overlooking something??

Thanks

Well, I finally managed to get a NSView (or even a CALayer) to be displayed over the VLCVideoView after many many hours of tinkering.
The weird thing is that the layer initially appears behind the VLCVideoView, but when you make the window as small as possible and then bring it back to the size you want it to be, suddenly the layer appears on top of the VLCVideoView.
I have no idea why, but hey ho it works

Here's the awakeFromNib of the NSView that contains both the VLCVideoView and the overlay, maybe it's of use to someone else...

Code: Select all

- (void)awakeFromNib {
	videoView = [[VLCVideoView alloc] initWithFrame:NSMakeRect(0,0,self.frame.size.width, self.frame.size.height)];
	[self addSubview:videoView];
	[videoView release];
	
	player = [[VLCMediaPlayer alloc] initWithVideoView:videoView];
	[player setMedia:[VLCMedia mediaWithURL:[NSURL URLWithString:@"udp://@224.99.1.1:1234"]]];
	[player play];
	
	NSView *extraView = [[NSView alloc] initWithFrame:NSMakeRect(100,200,self.frame.size.width/5, self.frame.size.height/5)];
	[self addSubview:extraView];
	[extraView setWantsLayer:YES];
	[extraView.layer setBackgroundColor:CGColorCreateGenericRGB(1.0, 0.0, 0.0, 0.5)];	
}

Hi, I found the same error with subviews when I try add subview to VLCVideoView.

I need a solution programatically. I can't say to my users: "if you make the window as small as possible and then bring it back to the size you want it to be my application run ok"

.

Skip o other user found a solution in the code. Excuse my horrible english and thank you.
