The equipment is connected to the easycvr platform through the national standard gb28181. How to solve the problem of disconnection?

TSINGSEE The deployment of various platforms of Qingxi video is flexible , Rich and comprehensive video capabilities 、 It can meet the needs of users for multi scene video surveillance , Each platform has its own characteristics , Can support multiple types of devices 、 Multi protocol access , Including the national standard GB28181 agreement 、RTMP/RTSP/Onvif agreement 、 The sea, EHOME、 The sea, SDK、 Dahua SDK etc. , On video streaming distribution , It can support all terminals 、 Full platform video stream output , Include RTSP、FLV、HLS、WebRTC Equiform .

There's user feedback EasyCVR The video stream distributed by the platform will be automatically cut off after a period of time , We checked this situation .

resolvent ： First, open the video normally , Switch to FLV stream , Copy Stream Address , adopt VLC Play . If VLC To break off , It means that the flow is disconnected . After a period of observation , There is a cut-off , So we quickly use wireshark Carry out the bag , And carry out flow pulling operation , However, at this time, there was no success in pulling the flow .

Then export the captured package , Type... In the input box sip, find invite request , an Body, Get udp port .

Input again udp.port == 50196, No data found .

thus it can be seen , In case of disconnection , We send a message to the device invite request , Equipment not returned RTP flow , It is judged that there is an exception at the device end , It is recommended that the user check the equipment .

EasyCVR The platform relies on flexible video capabilities 、 Strong expandability 、 High compatibility 、 Features such as lightness of deployment , It has been used in a large number of projects , Such as smart construction site 、 Smart factory 、 Smart campus 、 Safe campus 、 Safe city 、 Bright kitchen, bright stove, etc . Interested users can go to the demonstration platform for experience or deployment testing .
