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 }
其实就是靠一个字段来判断何时可以录像。
举个例子:
{“Monday”:"",“Tuesday”:“15:00:00-16:00:00”,“Wednesday”:"",“Thursday”:"",“Friday”:"",“Saturday”:"",“Sunday”:""}
比如上面的这一个字符串,意思就是只会在星期2的下午3点到下午4点录像,其他时间段不录像。
