Play Moto Chaser for iPhone… on Your TV?!

A week or so ago we linked to Erica Sadun’s demo of the iPhone SDK’s undocumented video out feature. Well, she’s been busy since then talking with Freeverse, the developers behind the hit Moto Chaser game for the iPhone. The result? The tech demo featured above.

Good news is that the possibilities are mind-boggling. Bad news is that we’re not there yet:

On the 2G touch, Moto Chaser can reach approximately 20 frames per second. This makes the game, in the words of Freeverse Producer Bruce Morrison, “nearly playable.” Morrison manages the Freeverse product teams and was heavily involved in developing Moto Chaser; he designed all the levels in the game. The norm for commercial games is 30fps, a point at which motion becomes as smooth and watchable as normal TV video. For reference, the current iPhone release of Moto Chaser runs at 26fps and includes many optimizations to achieve even that on the iPhone’s relatively slow processor and limited RAM memory.

Hacking Away at iPhone 2.2 TV-Out Secrets


Updated iPhone with live Video Out from Ars Technica on Vimeo.

A few days ago we mentioned Ars’ iPhone expert, Erica Sadun was taking the lifting of iPhone OS 2.2’s NDA as an opportunity to dump code and sift for gold. Turns out she’s not only found some in the way of “hidden” TV-out features in iPhone 2.2, she’s sacrificed her well earned turkey day to experiment with them. From her previous post, here’s what’s at work:

The MPTVOutWindow class allows your iPhone to send its video to a connected TV rather than to the built-in screen. Intended to be used with movies, the unpublished class creates a live video feed that is sent out through the iPhone’s connector port. End-users will need to buy a video adapter or cable to use this functionality.

Early days still, but fairly awesome stuff. Can’t wait to see what she and other developers — not to mention Apple eventually — come up with!
