Protocol

Swift

/// The protocol for device API that supports camera.
protocol DeviceCameraAPI: DeviceAPI {
    /// Maximum video recording duration (in minutes) allowed by the device.
    var maxVideoRecordDuration: NSNumber? { get }

    /// Sets the maximum video recording duration.
    /// - Parameters:
    ///   - duration: The maximum recording duration in minutes.
    ///   - completion: A closure that is called when the operation completes.
    ///     - success: `true` if the operation was successful; otherwise `false`.
    ///     - error: An `NSError` object that describes the error that occurred, or `nil` if the operation was successful.
    func setMaxVideoRecordDuration(
        _ duration: Int,
        completion: AIBudsCompletionHandler?
    )
}

Objective-C

/// The protocol for device API that supports camera.
@protocol AIBudsDeviceCameraAPI <AIBudsDeviceAPI>
    /// Maximum video recording duration (in minutes) allowed by the device.
    @property (nonatomic, readonly, strong) NSNumber * _Nullable maxVideoRecordDuration;

    /// Sets the maximum video recording duration.
    /// - Parameters:
    ///   - duration: The maximum recording duration in minutes.
    ///   - completion: A closure that is called when the operation completes.
    ///     - success: `true` if the operation was successful; otherwise `false`.
    ///     - error: An `NSError` object that describes the error that occurred, or `nil` if the operation was successful.

        completion:(AIBudsCompletionHandler _Nullable)completion;

Symbol	Purpose

setMaxVideoRecordDuration	Set the maximum duration in minutes.

Usage Examples

Swift

guard let device = device as? DeviceCameraAPI else { return }
print("Current maximum: \(device.maxVideoRecordDuration?.intValue.description ?? "Unavailable") minutes")

device.setMaxVideoRecordDuration(30) { success, error in
    if !success { print(error?.localizedDescription ?? "Update failed") }
}

Objective-C

id<AIBudsDeviceCameraAPI> device = (id<AIBudsDeviceCameraAPI>)self.device;
if ([device conformsToProtocol:@protocol(AIBudsDeviceCameraAPI)]) {
    NSLog(@"Current maximum: %@ minutes", device.maxVideoRecordDuration);
    [device setMaxVideoRecordDuration:30 completion:^(BOOL success, NSError * _Nullable error) {
        if (!success) NSLog(@"Update failed: %@", error.localizedDescription);
    }];
}

The current Demo uses a 1...120 minute slider. The public SDK does not document a universal range, so treat those limits as a Demo convention pending a public capability.
