CBLCameraVideoRecording

Objective-C

@protocol CBLCameraVideoRecording <NSObject>

Swift

protocol CameraVideoRecording : NSObjectProtocol

Video recording methods.

  • Returns YES if the camera is currently recording video, otherwise NO. Will update if video recording is started or stopped using the camera’s on-body controls, or if video recording stopped due to the card being full etc.

    Can be observed with Key-Value Observing.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL isRecordingVideo;

    Swift

    var isRecordingVideo: Bool { get }

  • If available, returns the current value of the camera’s video recording timer. Can be observed with Key-Value Observing.

    The returned value is immutable — a new value will be created when the timer updates.

    Will be nil when the camera isn’t recording video.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) id<CBLVideoTimerValue> currentVideoTimerValue;

    Swift

    @NSCopying var currentVideoTimerValue: VideoTimerValue? { get }

  • Start video recording.

    Will fail if the camera is already recording video, the camera isn’t in a mode that allows video recording, or if some other condition prevents video recording to start (not enough space on the camera’s storage card, etc).

    Declaration

    Objective-C

    - (void)startVideoRecording:
    (nullable CBLErrorableOperationCallback)completionHandler;

    Swift

    func startVideoRecording() async throws

  • End video recording.

    Declaration

    Objective-C

    - (void)endVideoRecording:
    (nullable CBLErrorableOperationCallback)completionHandler;

    Swift

    func endVideoRecording() async throws
