# DefaultCameraCaptureSource

`class DefaultCameraCaptureSource : CameraCaptureSource, VideoSink`

DefaultCameraCaptureSource will configure a reasonably standard capture stream which will use the Surface provided by the capture source provided by a SurfaceTextureCaptureSourceFactory

### Constructors

#### <init> | DefaultCameraCaptureSource will configure a reasonably standard capture stream which will use the Surface provided by the capture source provided by a SurfaceTextureCaptureSourceFactory `DefaultCameraCaptureSource(context: Context, logger: Logger, surfaceTextureCaptureSourceFactory: SurfaceTextureCaptureSourceFactory, cameraManager: CameraManager = context.getSystemService( Context.CAMERA_SERVICE ) as CameraManager)`

### Properties

#### contentHint | Content hint for downstream processing `val contentHint: VideoContentHint`
#### device | Current camera device. This is only null if the phone/device doesn't have any cameras May be called regardless of whether start or stop has been called. `var device: MediaDevice?`
#### eventAnalyticsController | `var eventAnalyticsController: EventAnalyticsController?`
#### format | Current camera capture format. Actual format may be adjusted to use supported camera formats. May be called regardless of whether start or stop has been called. `var format: VideoCaptureFormat`
#### torchEnabled | Toggle for torch on the current device. Will succeed if current device has access to flashlight, otherwise will stay false. May be called regardless of whether start or stop has been called. `var torchEnabled: Boolean`

### Functions

#### addCaptureSourceObserver | Add a capture source observer to receive callbacks from the source on lifecycle events which can be used to trigger UI. This observer is entirely optional. `fun addCaptureSourceObserver(observer: CaptureSourceObserver): Unit`
#### addVideoSink | Add a video sink which will immediately begin to receive new frames. `fun addVideoSink(sink: VideoSink): Unit`
#### onVideoFrameReceived | Receive a video frame from some upstream source. The VideoSink may render, store, process, and forward the frame, among other applications. `fun onVideoFrameReceived(frame: VideoFrame): Unit`
#### release | `fun release(): Unit`
#### removeCaptureSourceObserver | Remove a capture source observer `fun removeCaptureSourceObserver(observer: CaptureSourceObserver): Unit`
#### removeVideoSink | Remove a video sink which will no longer receive new frames on return `fun removeVideoSink(sink: VideoSink): Unit`
#### setMaxResolution | Set max resolution for video capture source DefaultCameraCaptureSource and DefaultScreenCaptureSource call this function to set max resolution for camera and screen capture `fun setMaxResolution(maxResolution: VideoResolution): Unit`
#### start | Start capturing on this source and emitting video frames `fun start(): Unit`
#### stop | Stop capturing on this source and cease emitting video frames `fun stop(): Unit`
#### switchCamera | Helper function to switch from front to back cameras or reverse. This also switches from any external cameras to the front camera. `fun switchCamera(): Unit`
