Easycvr Video Square snapshot adding device channel offline reason display

EasyCVR The platform supports multiple protocols 、 Multiple types of device access , Have flexible and rich video capabilities , The realizable functions include real-time video monitoring and live broadcasting 、 Cloud video 、 Cloud storage 、 Playback and retrieval 、 Intelligent alarm 、 Video snapshot 、 Video transcoding and distribution 、 Platform cascade, etc .

There's user feedback , In the use of EasyCVR During on-site operation , Sometimes I come across RTSP The access channel shows the offline situation , But I don't know why , I hope technicians can help optimize .

After receiving feedback , Technicians developed this requirement . The functional design logic is as follows ：

First, detect the offline status of the channel , When the channel configuration is detected RTSP After the address cannot get the data information correctly , Store the cause and status of the error into the corresponding channel , When the front-end call gets the channel information and returns , Return the corresponding error message to the display .

The reference codes are as follows ：

 for _, value := range *channels {
		clusterInfo, _ := clusterMap[value.ServerID]
		tdevID := -1
		tdevName := ""
		if devInfo {
			tv, tok := devList.Get(fmt.Sprintf("%s", value.ParentDeviceID))
			if tok {
				mv, mok := tv.(cvrdo.Device)
				if mok {
					tdevID = int(mv.DeviceID)
					tdevName = mv.DeviceName
				}
			} else {
				tdev, e := cvrdao.GetDeviceDao().Get(value.ParentDeviceID)
				if e == nil {
					devList.Set(fmt.Sprintf("%s", value.ParentDeviceID), *tdev, -1)
					tdevID = int(tdev.DeviceID)
					tdevName = tdev.DeviceName
				}

And when I'm done , Check the offline channel effect again , The snapshot page has displayed the prompt that the device is offline , It helps to quickly locate problems during troubleshooting .

EasyCVR The video fusion cloud platform has rich video capabilities 、 Strong compatibility 、 High openness , It can be used for a variety of terminals （PC The computer 、 mobile phone 、 Flat 、 Electronic large screen, etc ） distribution RTSP、RTMP、FLV、HLS、WebRTC Video streams of the same format , In terms of video access, it can also support most video monitoring devices on the market , It can be done by GB28181、RTMP、RTSP/Onvif、 The sea, SDK、 Dahua SDK、Ehome And other protocols , Interested users can go to the demonstration platform for experience or deployment testing .
