Package-level declarations

Types

class CameraSettings(context: Context, cameraController: CameraController)

Use to change camera settings. This object is returned by BaseCameraStreamer.settings.camera.

ChunkedFileOutputStream

class ChunkedFileOutputStream(val filesDir: File, chunkSize: Int, chunkNameGenerator: (Int) -> String = { id -> "chunk_$id" }, listener: ChunkedFileOutputStream.Listener = object : Listener {}) : OutputStream

A class that allows to write into multiple files. It is useful when you want to upload a file to a server but you don't want to wait for the record to finish before. Use this class as an OutputStream of a IFileStreamer.

class Exposure(context: Context, cameraController: CameraController)

class Flash(context: Context, cameraController: CameraController)

class Focus(context: Context, cameraController: CameraController)

class FocusMetering(context: Context, cameraController: CameraController, zoom: Zoom, focus: Focus, exposure: Exposure, whiteBalance: WhiteBalance)

class Iso(context: Context, cameraController: CameraController)

NotificationUtils

class NotificationUtils(service: Service, channelId: String, notificationId: Int)

Helper class to create and manage notifications. Only use for screen recording service that is why the permission error is suppressed.

OrientationUtils

object OrientationUtils

class Stabilization(context: Context, cameraController: CameraController)

class WhiteBalance(context: Context, cameraController: CameraController)

sealed class Zoom
