PBJVision

'PBJVision' is an iOS camera engine that supports touch-to-record video and photo capture. It is compatible both iOS 6 and iOS 7 as well as 64-bit. Pause and resume video capture is also possible without having to use a gesture like the sample project provides.

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

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