How to Airpl

TUAW's Erica Sadun, if ever a wiz there was, has once again hacked away at Apple's iOS 4.2 AirPlay feature and created an app called AirPlayer that gets it to stream video from iPhone or iPad to the Mac.

What AirPlayer does is create and advertise a custom Bonjour AirPlay service that pretends to be an Apple TV. Bonjour is Apple's zero configuration networking solution for allowing devices and applications to communicate with each other over local area networks. When Apple created AirPlay, it basically set up a new way for Apple TV to interact with iOS using Bonjour communications.

She's not a Windows dev but says in theory the same thing should be possible on that platform and perhaps Linux as well.

You don't need to Jailbreak to try this out (the app runs on your Mac, not your iPhone or iPad) but if you're not Jailbroken and running AirVideoEnabler you'll be limited to YouTube and iPod/Videos for your streaming (AirVideoEnabler lets 3rd party apps stream AirPlay video as well).

If you want to try it out, you can get AirPlayer from Erica's website, below. Video after the break!

Dev tip: Hacking AirPlay for 3rd party apps

iOS developer extraordinaire Erica Sadun decided to take a look into iOS 4.2's AirPlay feature (and see if she could figure out why it was restricted to audio-only outside Apple's YouTube and iPod/Video apps (i.e. there are only audio AirPlay API currently available to 3rd party App Store developers). Here's what she's found so far:

Having gotten this proof of concept working, there's still a lot left to get done to transform this into a stable solution that works with general applications. Keep in mind that you'll be working with unpublished APIs, so the above classes and code are not App Store Safe. That's why we have a jailbreak world, after all.

The bad news is it looks like it will take an "Act of Apple" to get proper, video-supporting AirPlay API into developers hands and into App Store apps. (So developers, get thee to the bug report system and ask for this to be fixed and surfaced asap). The good news, at least for now, is that Steven Troughton-Smith has reduced the process to a single line of code, eliminating the YouTube work-around.

Yes, it still won't be App Store safe, but it's jailbreak friendly, works flawlessly, and suggests only a single item that Apple could move to a public API to open up this functionality to developers. What's more, with a little screen scraping or off-screen layer manipulation and a clever use of AVFoundation, you can probably have games working out to Apple TV almost immediately.

Indeed...! Check out her full post via the link below for details on how it all works.

Push Notification a Burden to Small Developers?

Apple has gone out of their way to point out the cons of multi-tasking background applications -- a claimed 80% reduction in battery life while on standby with a single 3rd party IM client enabled. Push Notification, likewise, has been promoted by Apple as providing a single point of coordination for 3rd party alerts routed through servers on Apple's end.

But unlike the code-once, release-done model of background processing for a single app, Push Notification requires developers to create a server system on their end as well, one that's constantly and reliably available to send alerts to Apple, and scales to an iPhone and iPod touch user base already exceeding 30 million units.
