RTSP协议视频智能流媒体服务平台EasyNVR录像计划功能实现过程

之前的博文中我们和大家讲过EasyNVR的录像计划的实现方式，大家可以简单了解一下操作方式：EasyNVR边缘计算网关录像计划功能操作介绍。关于EasyNVR录像计划的实现，TSINGSEE青犀视频的研发人员也耗费了不少心思，下面我们就讲一下是是如何实现的。

EasyNVR录像计划，其实就是在EasyNVR先为通道配置好录像计划，然后该通道就会以录像计划中的计划设置来录像。例如：通道1只开启每天的下午1点到2点录像，那么通道1就只会在每天的下午1点到2点有录像，不会像现在一旦开启录像，就是直接录像一整天。

这样就可以达到节省磁盘空间的效果，录像也更灵活。下面是实现代码：

func checkRecordPlan() gin.HandlerFunc {
   return func(c *gin.Context) {
      c.Request.ParseForm()
      log.Printf("----------form:%s", c.Request.Form)
      app := c.Request.Form.Get("app")
      call := c.Request.Form.Get("call")
      name := c.Request.Form.Get("name")
      channelId, _ := strconv.Atoi(name[7:])
      if app == "record" && (call == "update_publish" || call == "publish") {
         var camera models.Camera
         models.DB.Model(models.Camera{}).Where("id = ?", channelId).First(&camera)
         recordDay, _ := strconv.Atoi(camera.Reserve3)
         if recordDay != 0 {
            log.Printf("----------RecordAllPlan:%s", camera.RecordAllPlan)
            if camera.RecordPlanEnable == 0 && camera.RecordAllPlan != "" {
               if !checkTimeByRecordPlan(camera.RecordAllPlan) {
                  channelInfo := channels.GetChannel(uint(channelId))
                  channelInfo.StopRecordPusher()
                  c.AbortWithStatus(http.StatusBadRequest)
                  return
               }
            }
            //{"Monday":"","Tuesday":"15:50:00-16:00:00","Wednesday":"","Thursday":"","Friday":"","Saturday":"","Sunday":""}
            if camera.RecordPlanEnable == 1 && camera.RecordPlan != "" {
               if !checkTimeByRecordPlan(camera.RecordPlan) {
                  channelInfo := channels.GetChannel(uint(channelId))
                  channelInfo.StopRecordPusher()
                  c.AbortWithStatus(http.StatusBadRequest)
                  return
               }
            }
         }
      }
      c.Next()
   }
}
  
func CheckTimeUnix(timeArr []string) bool {
   if timeArr[0] == "" {
      return false
   }
   stampStart, _ := time.ParseInLocation("2006-01-02 15:04:05", time.Now().Format("2006-01-02")+" "+timeArr[0], time.Local)
   stampEnd, _ := time.ParseInLocation("2006-01-02 15:04:05", time.Now().Format("2006-01-02")+" "+timeArr[1], time.Local)
   stampNow := time.Now().Unix()
   if stampNow >= stampStart.Unix() && stampNow <= stampEnd.Unix() {
      return true
   }
   return false
}
