Inherits from NSObject
Declared in TVICameraSourceOptions.h

Overview

TVICameraSourceOptionsBuilder is a builder class for TVICameraSourceOptions.

  enableCameraMultitasking

Allows the developer to enable support for camera multi tasking. When this is supported by the device, setting this option to true will allow the camera to continue running when the video applicaiton is put in background, or on a splitted view.

@property (nonatomic, assign) BOOL enableCameraMultitasking

Discussion

Only a few apple devices supports this features. Twilio Video SDK will enable this feature by default when possible.

  orientationTracker

Allows the developer to customize how TVICameraSource tracks video orientation for capture and preview.

@property (nonatomic, strong, nonnull) id<TVICameraSourceOrientationTracker> orientationTracker

Discussion

Defaults to +[TVIUserInterfaceTracker tracker] which monitors -[UIApplication statusBarOrientation].

When a tracker is created with +[TVIUserInterfaceTracker trackerWithScene:], TVICameraSource monitors for UISceneWillEnterForegroundNotification. Otherwise, the source monitors for UIApplicationWillEnterForegroundNotification.

You can also manually control how orientation is tracked. For example, you might decide to use UIDevice instead of UIScene to determine the orientation of the camera.

Note that the video data output connection is configured for the native orientation of the camera sensor. The connection is set to AVCaptureVideoOrientationLandscapeLeft for front facing devices, and AVCaptureVideoOrientationLandscapeRight for rear facing devices. For example, if you are holding your iOS device in AVCaptureVideoOrientationLandscapeLeft (UIDeviceOrientationLandscapeRight) with the front camera facing towards you, then no rotation is required and the correct tag would be TVIVideoOrientationUp.
