TVICameraSourceOptions Class Reference

Inherits from NSObject
Declared in TVICameraSourceOptions.h

Overview

Represents immutable configuration options for a TVICameraSource.

  orientationTracker

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

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

Discussion

Defaults to +[TVIUserInterfaceTracker tracker].

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 video from 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.
