The video functions that can be realized include: real-time monitoring live broadcast, video recording, retrieval and review, voice intercom, cloud storage, alarm, platform Cascading and other functions. The national standard GB28181 video surveillance platform is easy to deploy and highly expandable. It supports the distribution of the accessed video streams across all terminals and platforms. The distributed video streams include RTSP, RTMP, FLV, HLS, WebRTC and other formats.
Some users reported that the EasyGBS national standard GB28181 platform failed to play when playing, and the packet capture check returned ICMP, and asked us to assist in troubleshooting. Today we will share the troubleshooting and solution steps.
1) We found the problem through packet capture analysis. First, the first invite request was at 16:41:06 seconds, and we can see that the requested rtp port is 58422;
2) During the time of sip transmission, 5s has been a concept for a long time. If the audio and video national standard platform EasyGBS does not receive the RTP stream sent by the device within 5s, it will judge that the playback has failed and send a Bye actively End this invite interaction;
3) From the packets captured, we can see that the device does not send streams, because the time delay of the device to send streams is about 6s, so we can see that the device does send rtp streams, and it is to 58422 Sent by the rtp stream port;
4) The system judges that port 58422 is invalid, because the national standard GB28181 video platform EasyGBS has unbound port 58422, so there is no service occupying port 58422, which causes the server to think that this port is not used and reply ICMP to the device;
5) After judging that the national standard GB28181 security monitoring platform EasyGBS and the normal sip interaction delay of the field equipment is very low, so it should have nothing to do with the network transmission. It is recommended that the user check on the equipment side. After the user's investigation and on-site equipment upgrade, the above problems have been resolved.
Video streaming security monitoring national standard GB28181 platform EasyGBS has rich video capabilities and flexible deployment. It can be used not only as a business platform, but also as a security monitoring video capability layer to be invoked by the business management platform. The national standard GB28181 video EasyGBS platform can provide streaming media access, processing, forwarding and other services, and supports the security video surveillance equipment of the intranet and public network to conduct video surveillance live broadcast through the national standard GB/T28181 protocol.
