PBJVision

'PBJVision' is an iOS camera engine that supports touch-to-record video and photo capture. It supports both iOS 6 and iOS 7 as well as 64-bit.

We created this at DIY.org as a fun means for kids to author video. This same recording interaction was pioneered by Vine and later by Instagram.

Please review the release history for more information. If you need a video player, check out PBJVideoPlayer.
