PBJVision

PBJVision

'PBJVision' is an iOS camera engine that supports touch-to-record video 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.

Please review the release history for more information. If you have questions or ideas, let me know! The github issues page is a great place to start a discussion but also allows others to benefit and chime in on the project too.

Installation

CocoaPods is the recommended method of installing PBJVision, just add the following line to your Podfile:

Podfile

pod 'PBJVision'

#import "PBJVision.h"

        {
            if (!_recording)
                [[PBJVision sharedInstance] startVideoCapture];
            else
