CameraEngine is an iOS camera engine library that allows easy integration of special capture features and camera customization in your iOS app.

:fire: Features

🔨 Installation

CocoaPods

• Add pod "CameraEngine" to your Podfile.
• Run pod install or pod update.
• import CameraEngine

Carthage

• Add github "remirobert/CameraEngine" to your Cartfile.
• Run carthage update and add the framework to your project.
• import CameraEngine

Manually

• Download all the files in the CameraEngine subdirectory.
• Add the source files to your Xcode project.
• import CameraEngine

To add the Framework, you can also create a workspace for your project, then add the CameraEngine.xcodeproj, and the CameraEngine, then you should be able to compile the framework, and import it in your app project.

CameraEngine supports swift3, see the development branch for a swift 3 integration.

:rocket: Quick start

First let's init and start the camera session. You can call that in viewDidLoad, or in appDelegate.

override func viewDidLoad() {
  super.viewDidLoad()
  self.cameraEngine.startSession()
}

Next time to display the preview layer

override func viewDidLayoutSubviews() {
  let layer = self.cameraEngine.previewLayer
        
  layer.frame = self.view.bounds
  self.view.layer.insertSublayer(layer, atIndex: 0)
  self.view.layer.masksToBounds = true
}

Capture a photo

self.cameraEngine.capturePhoto { (image: UIImage?, error: NSError?) -> (Void) in
  //get the picture tooked in the 👉 image
}

Capture a video

private func startRecording() {
  guard let url = CameraEngineFileManager.documentPath("video.mp4") else {
    return
  }
            
  self.cameraEngine.startRecordingVideo(url, blockCompletion: { (url, error) -> (Void) in
  })
}

private func stopRecording() {
  self.cameraEngine.stopRecordingVideo()
}

Generate animated image GIF

guard let url = CameraEngineFileManager.documentPath("animated.gif") else {
  return
}
self.cameraEngine.createGif(url, frames: self.frames, delayTime: 0.1, completionGif: { (success, url) -> (Void) in
  //Do some crazy stuff here
})

:wrench: configurations

CameraEngine, allows you to set some parameters, such as management of flash, torch and focus. But also on the quality of the media, which also has an impact on the size of the output file.

Flash

self.cameraEngine.flashMode = .On
self.cameraEngine.flashMode = .Off
self.cameraEngine.flashMode = .Auto

Torch

self.cameraEngine.torchMode = .On
self.cameraEngine.torchMode = .Off
self.cameraEngine.torchMode = .Auto

Focus

          |  CameraEngine focus

--------------------------|------------------------------------------------------------ .Locked | means the lens is at a fixed position .AutoFocus | means setting this will cause the camera to focus once automatically, and then return back to Locked .ContinuousAutoFocus | means the camera will automatically refocus on the center of the frame when the scene changes

self.cameraEngine.cameraFocus = .Locked
self.cameraEngine.cameraFocus = .AutoFocus
self.cameraEngine.cameraFocus = .ContinuousAutoFocus

Camera presset Photo

self.cameraEngine.sessionPresset = .Low
self.cameraEngine.sessionPresset = .Medium
self.cameraEngine.sessionPresset = .High
...

Camera presset Video

self.cameraEngine.videoEncoderPresset = .Preset640x480
self.cameraEngine.videoEncoderPresset = .Preset960x540
self.cameraEngine.videoEncoderPresset = .Preset1280x720
self.cameraEngine.videoEncoderPresset = .Preset1920x1080
self.cameraEngine.videoEncoderPresset = .Preset3840x2160

:eyes: Object detection

CameraEngine can detect faces, QRcodes, or barcode. It will return all metadata on each frame, when it detects something. To exploit you whenever you want later.

Set the detection mode

self.cameraEngine.metadataDetection = .Face
self.cameraEngine.metadataDetection = .QRCode
self.cameraEngine.metadataDetection = .BareCode
self.cameraEngine.metadataDetection = .None //disable the detection

exploiting face detection

self.cameraEngine.blockCompletionFaceDetection = { faceObject in
  let frameFace = (faceObject as AVMetadataObject).bounds
  self.displayLayerDetection(frame: frameFace)
}

exploiting code detection (barecode and QRCode)

self.cameraEngine.blockCompletionCodeDetection = { codeObject in
  let valueCode = codeObject.stringValue
  let frameCode = (codeObject as AVMetadataObject).bounds
  self.displayLayerDetection(frame: frameCode)
}

:car::dash: Example

You will find a sample project, which implements all the features of CameraEngine, with an interface that allows you to test and play with the settings. To run the example projet, run pod install, because it uses the current prod version of CameraEngine.
