The impassioned pleas of one developer e-mailed to Steve Jobs resulted in a quick reversal of his app's rejection. The launch of the app today is the first known approved app that can stream live video directly from one iPhone to another, and the first approval for an app with known use of private APIs. Apple's change of heart came "directly from the top," and is a sign that real change in the App Store approval process is in the works.
A persuasive e-mail from an iPhone developer to Steve Jobs helped Pointy Heads Software get its Knocking Live Video—the first official iPhone app capable of streaming live video over 3G and WiFi connections—approved for sale in the App Store. The app relies on a private API—well-known among iPhone developers—to enable its video streaming feature, so its approval is a good sign for other companies developing video-based apps. It's also a good sign that Apple is taking developer complaints with the App Store approval process seriously.
Knocking Live Video uses an interesting take on streaming video. Unlike Qik, which is designed to stream video to multiple clients, Knocking streams from one iPhone to another. (It should be noted that the iPhone version of Qik wasn't approved with live streaming—it can only upload the video to Qik's website after recording for later streaming.) You simply launch the app and "knock" another iPhone user with Knocking Live Video installed. That user will receive the "knock" via push notification. Once answered, you can then stream live video directly to them. An iPhone 3GS or iPhone 3G is required to transmit video, but other iPhones and iPod touches can receive and view the stream via WiFi.
"We are focused on phone-to-phone, not uploading to the Web," Pointy Head developer Brian Meehan explained to Ars. "Who really cares about fleeting moments other than friends and family seeing it as it happens? With Knocking people share what they are doing right now. Our testers have referred to knocking as a 'visual tweet,'" he said.
To make its magic work, the app relies on use of a private API that enables capturing frames live from the iPhone's screen. "Our app uses a form of screen capture to create live moments which we have built a complex algorithm around," Meehan told Ars. However, use of private APIs—internal programming functions and methods that aren't approved for developer use—is a direct violation of Apple's iPhone developer agreement. It goes without saying that Knocking Live Video was promptly rejected about 30 days ago for violating this clause.
