IVSImageDevice

Objective-C

@protocol IVSImageDevice <IVSDevice>

Swift

protocol IVSImageDevice : IVSDevice

This represents an IVSDevice that provides video samples.

  • Sets the current rotation of the video device. This will be used to transform the output stream

    This is handled automatically when attaching a camera via an IVSDeviceDescriptor.

    Declaration

    Objective-C

    - (void)setHandsetRotation:(float)rotation;

    Swift

    func setHandsetRotation(_ rotation: Float)

    Parameters

    rotation

    The rotation in radians

  • Gets a view that will render a preview image of this device.

    Note

    this must be called on the main thread

    Declaration

    Objective-C

    - (nullable IVSImagePreviewView *)previewViewWithError:
    (NSError *_Nullable *_Nullable)outError;

    Swift

    func previewView() throws -> IVSImagePreviewView

    Parameters

    outError

    On input, a pointer to an error object. If an error occurs, the pointer is an NSError object that describes the error. If you don’t want error information, pass in nil.

  • Gets a view that will render a preview image of this device with the provided aspect ratio.

    Note

    this must be called on the main thread

    Declaration

    Objective-C

    - (nullable IVSImagePreviewView *)
    previewViewWithAspectMode:(IVSAspectMode)aspectMode
                        error:(NSError *_Nullable *_Nullable)outError;

    Swift

    func previewView(with aspectMode: IVSBroadcastConfiguration.AspectMode) throws -> IVSImagePreviewView

    Parameters

    aspectMode

    the aspect mode to apply to the image stream rendering on the view.
    outError

    On input, a pointer to an error object. If an error occurs, the pointer is an NSError object that describes the error. If you don’t want error information, pass in nil.
