Easycvr accesses the equipment through the national standard gb28181 protocol. What is the reason for the automatic streaming of the equipment?

EasyCVR On the access protocol , Not only support the national standard GB28181 agreement 、RTSP/Onvif、RTMP Standard agreement , And support HIKSDK、 Dahua SDK、 The sea, Ehome Such as the factory furniture has an agreement with SDK, Distributable RTSP、RTMP、FLV、HLS、WebRTC And other video streams in various formats . The platform can be expanded flexibly , The video functions that can be realized include ： Live video surveillance 、 Cloud video 、 Cloud storage 、 Video retrieval and review 、 Intelligent alarm 、 Platform cascade, etc . Recently, we are working on EasyCVR Expand new functions , For example, server clusters 、 Video rounds 、H.265 transcoding H.264、 Electronic map and track tracking, etc , Welcome to pay attention to our update .

There's user feedback , Use EasyCVR In the process of platform , Passed the national standard GB28181 The protocol connects the device to , There is an automatic flow pulling phenomenon , Ask us for assistance in troubleshooting . Today, let's share the troubleshooting and solutions .

We preliminarily judge that some signaling of the device may trigger the platform to pull the flow .

So you can view by capturing packets , You can see , When the longitude and latitude of the equipment change , The platform is pulling the stream to get the device GPS Location snapshot information .

In view of the above situation , It can be optimized as follows ： In the device GPS When longitude and latitude change , Judge whether the map changes in real time , According to this condition, decide whether to pull the stream to get a snapshot . The reference codes are as follows ：

for _, v := range channels {
				cha := cvrservice.GetDeviceService().GetDBChannelGBId(v.DeviceID, v.ID)
				if cha != nil {
					ParentDeviceID := strconv.Itoa(int(cha.ParentDeviceID))
					ChannelID := strconv.Itoa(int(cha.ChannelID))
					_gps := models.Gps{
						DeviceID:    ParentDeviceID,
						ChannelID:   ChannelID,
						Longitude:   Longitude,
						Latitude:    Latitude,
						GBDeviceID:  v.DeviceID,
						GBChannelID: v.ID,
					}
					_, err := models.AddGps(&_gps)
					if err != nil {
						log.Println("add gps error :", err.Error())
					}
				}

Test again after optimization , Playback has returned to normal .

EasyCVR The platform supports massive video access convergence , Through the unified aggregation and centralized management of decentralized video resources , Realize the integration of resources 、 Processing and distribution , Combine various application scenarios , Realize resource sharing 、 Linkage common pipe . The platform can provide unified services API Interface , Connect devices 、 Connect data 、 Connect applications , Facilitate the rapid integration of third-party platforms .

With AI The continuous application of Technology ,EasyCVR The platform is also actively integrating video intelligent detection and analysis technology , Including face detection 、 Face recognition 、 People flow statistics 、 Vehicle detection and identification 、 License plate recognition 、 Behavior recognition 、 Track tracking, etc . Yes EasyCVR Interested users of the platform , You can go to the demonstration platform for experience or deployment testing .
