Hi All,

I have an app in the store that uses Cocos2D and supports video out, but video out appears to be broken on Retinal Display devices running iOS 5.

The app is tappr.tv (v3), and was released back in March. Video out was working on my iPhone 4 as well as an iPod 4th Gen under iOS 4.x. When I updated to iOS 5 on each of these devices, video out stopped displaying. I'm using a standard Apple component video out cable.

This is occurring both in the shipping version of the app, as well as a recent build of a new version. I can confirm that the EAGLView itself is being added to the external UIScreen window because the window background is gray and the EAGLView clears to black. Furthermore, when I capture an OpenGL ES Frame in XCode 4.2, I can see that the rendering is taking place. Its just not being displayed on the external screen.

Also note that video out continues to work on both an iPad running iOS 4.x and an iPad 2 running iOS 5. It seems to be limited to Retina Display iDevices.

I can confirm that other apps, such as Video from Apple, still display video out under IOS 5, so it must be related to my app somehow?

Here is the gist of my code handling video out, all fairly standard stuff…

- (void)setupCocos2D
{
	[CCDirector setDirectorType:kCCDirectorTypeNSTimer];

	CCDirector	*director = [CCDirector sharedDirector];

	EAGLView	*glView = [EAGLView viewWithFrame:CGRectZero
                                   pixelFormat:kEAGLColorFormatRGBA8
                                   depthFormat:GL_DEPTH_COMPONENT16_OES
                            preserveBackbuffer:NO
                                    sharegroup:nil
                                 multiSampling:NO
                               numberOfSamples:0];
	glView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin |
								UIViewAutoresizingFlexibleRightMargin |
								UIViewAutoresizingFlexibleTopMargin |
								UIViewAutoresizingFlexibleBottomMargin |
								UIViewAutoresizingFlexibleWidth |
								UIViewAutoresizingFlexibleHeight;
	[director setOpenGLView:glView];
	[director setDeviceOrientation:kCCDeviceOrientationPortrait];
        [director enableRetinaDisplay:YES];

	[CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888];
}

- (void) startTVOut
{
        // is there more than one screen?
	NSArray* screens = [UIScreen screens];
	if ([screens count] <= 1)
	{
		return;
	}

	UIScreen        *external = [[UIScreen screens] objectAtIndex: 1];
        CGSize          maxSize = CGSizeMake(0, 0);
	UIScreenMode    *maxScreenMode = nil;
	for(int i = 0; i < [[external availableModes] count]; i++)
	{
		UIScreenMode *current = [[[[UIScreen screens] objectAtIndex:1] availableModes] objectAtIndex: i];
		if (current.size.width > maxSize.width)
		{
			maxSize = current.size;
			maxScreenMode = current;
		}
	}
	external.currentMode = maxScreenMode;
        CGRect          aFrame = CGRectMake(0,0, maxScreenMode.size.width, maxScreenMode.size.height);

	tvoutWindow_ = [[UIWindow alloc] initWithFrame:aFrame];
	tvoutWindow_.userInteractionEnabled = NO;
	tvoutWindow_.screen = external;
	tvoutWindow_.hidden = NO;
	tvoutWindow_.backgroundColor = [UIColor darkGrayColor];

	EAGLView	*glView = [[CCDirector sharedDirector] openGLView];
	glView.frame = tvoutWindow_.bounds;
	[tvoutWindow_ addSubview:glView];

        tvoutWindow_.hidden = NO;
}

Wondering if anyone else is seeing issues in their Cocos2D apps and video out? Anyone have a Cocos2D app that supports video out that IS working on a Retina Display iDevice?

peace

Hello! I'm implementing this (http://www.puzzle-light-up.com/) game. I've started by making a 120x120 grid placed in centre of my screen. I also created a 2D array. My idea was to make seperate files with lots of puzzles. In the files there would be a notation like this:
0=empty/unlit
1 = lit
2=filled in block with nothing in it
3=filled in block with 1 in it etc.
6 = has light bulb in it

Could you teach me a way to fill this 2D array with a seperate/external file. I was thinking of a loop which fills board[x][y]. Also, if you have any tips on how to represent the array visually after it's loaded please tell me.

Thank you :D
