The video surveillance aggregation platform EasyCVR has strong scalability, flexible video capabilities, and easy deployment. The mainstream standard protocols that can be supported include national standard GB28181, RTSP/Onvif, RTMP, etc., and support for private protocols and SDK access of manufacturers, including Hikvision Ehome, Hikvision Daewoo and other equipment's SDK, etc. The security monitoring platform EasyCVR not only has the capability of traditional security video surveillance, but also has the capability of accessing AI intelligent analysis, including intelligent tracking and identification analysis, capture, comparison, alarm reporting, and voice over events such as people, vehicles, objects, and behaviors reminder etc.
Recently, some users have reported that when playing on national standard GB devices connected to the EasyCVR platform, frequent interruptions occur. According to the user's feedback, the technicians immediately conducted investigations, and the following are the investigation and solution steps:
1) The technician found through packet capture: the EasyCVR platform will actively send the bye message, as shown in the figure below:
2) So I turned on the code debugging and found that only the first time the video stream is sent will send I frames, and no I frames will be sent other than that, so except for the first time it can be played normally, other clicks cannot be parsed to I frames ;
3) Since the site is connected with the national standard GB28181 protocol, the national standard GB protocol has a command to forcibly obtain I frames, and it is only necessary to execute the command to forcibly obtain I frames before each streaming, and the problem of no I frames can be solved question;
4) After following the above steps, the video will resume normal playback.
Centralized video storage/cloud storage/video surveillance management platform EasyCVR can gather, integrate, and centrally manage scattered various video resources in a complex network environment, and realize authentication management, on-demand access, and full-scale video resource management. Network distribution, intelligent analysis, etc. AI intelligence/big data video analysis EasyCVR platform has been widely used in construction sites, factories, parks, buildings, campuses, warehouses and other scenarios. Interested users can go to the demonstration platform for experience or deployment testing.
