This is great! Thanks for distilling this down to such a simple process.

It looks like this still works for iPhone under SDK 3.2 … but, alas, it doesn’t seem to work for iPad under SDK 3.2.

Does anyone know why? Or even have suggestions on how one (I) might find out?

Thanks.

Hi Rob and “The Evil Boss”,
thx for sharing this code. Really amazing…

The only Problem i am struggling with, is the 16 bit color output of my iphone 3g. It looks horrible . The output of the 3GS seem to be 24/32 bit. Did someone have the same problem.

Is there a way of using this code to provide a better version of the jailbreak app TV-Out (or similar)?

I’ve been trying to record app demos by using TV-Out, output to my Macbook, then using a screen recorder to capture this. But it’s not great, especially with high FPS games.

Aral, have you tried recording the video out of the app?

By the way, contrary to what I wrote above, this code DOES work with OpenGL. I have demoed games written with Unity 3D and Cocos2D using this. If you use a 3GS you can set the TVOut framerate to over 20 fps and it’s very acceptable.

@momo: I completely agree. I can’t believe that I’ve now spent longer on trying to record a high-quality demo video of my app than I did in coding the major functionality in it.

Enabling universal TV Out for iPhones makes makes perfect sense for apple as higher quality demo videos will translate to more sales and thus a higher income for Apple itself from its percentage of those sales.

Hello Rob,

wow thats pretty amazing, to have a code for that,…
I am not a coder and have no clue how to program,
but i have a question that i cannot get out of my head,
and after reading your post i even more surprised…
Why does apple not want to output video signals on apps or even better why do they not programm an app for video out? it is possible, the code is here and then the app will not survive Apple’s app review process. Why does apple do that? have you an answer? really sucks… i mean they are forcing people to jailbrake their ipods…
