PBJVision

'PBJVision' is an iOS camera engine that supports touch-to-record video, slow motion video (120 fps), and photo capture. It is compatible with both iOS 6 and iOS 7 and supports 64-bit. Pause and resume video capture is also possible without having to use a touch gesture as the sample project provides.

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

If you need a video player, check out PBJVideoPlayer.
