    var maxVideoRecordDuration: NSNumber? { get }

    /// Sets the maximum video recording duration.
    /// - Parameters:

符号	用途
maxVideoRecordDuration	当前最大时长，单位为分钟。
setMaxVideoRecordDuration	设置最大时长，单位为分钟。

使用示例

Swift

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

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);
                           }];
}

当前 Demo 使用 1...120 分钟滑块。公开 SDK 未说明统一范围，因此在公开能力提供前，应将该限制视为 Demo 约定。
