xcDeviceSDCalendar method

Future<List<String>> xcDeviceSDCalendar({
  1. required String deviceId,
  2. required DateTime monthDateTime,
  3. required String fileType,
  4. required String eventType,
  5. String rev = '',
  6. int timeout = 5000,
})

查询设备端媒体日历(SD卡) deviceId 设备序列号或IP+Port monthDateTime 查询日期，到月即可 eg:DateTime(2023,6) fileType 媒体文件类型 mp4：MP4录像，jpg：图片， idximg：索引图片， h264：录像 eventType 事件类型

Implementation

//  * ：全部录像或抓图
//  A ：外部报警录像或抓图
//  M ：动检报警录像或抓图
//  H ：手动录像或手动抓图
//  K ：关键录像或关键抓图
//  V ：紧急录像
//  R ：原始
//  P ：感应图片
//  I ：入侵
//  S ：滞留
//  U ：人形检测
//  F ：人脸检测
//  N ：车牌识别
//  G ：场景切换
