OS X Yosemite Now Uses iOS 8 For Video Capture
Recording video on an iOS 8 device is now possible using OS X Yosemite. The newest (and very beta) operating systems from Apple are meant to work in tandem, and news of an optional video recording utility are evidence of that. Of course, you need both new OSs for this to work right, so unless you're a Developer — it may not work out for you just yet.
This all comes by way of a new feature in OS X, found when plugging in an iOS device. When you tether an iPhone, iPad, or iPod running iOS 8 to a Mac running OS X Yosemite, the device shows up as a camera input option. From there, simply select it, and your screen is broadcast, and you can record or stream as needed.
This was probably included as part of Apple's push to get app videos into the App Store. A Developer could show off his app using this video capture method, and upload to the App Store. While it's useful there, there are many other reasons this is going to be useful to more of us.
Troubleshooting is likely going to get a lot easier, as is general tech support. Developers can use this to show off previews of their app to customers, or share with one another when designing games using Metal. We can also snap in-game footage and upload to Twitch if we like.
At the end of the day, it's a neat feature that is a touch overdue; but it's here now. Like all things iOS 8 and OS X Yosemite, it's in beta form. It's also laggy and buggy, so be prepared for that if you give it a shot.
