Cause analysis and solution of video jam after easycvr is connected to the device

EasyCVR The platform supports multiple types of devices 、 Multi protocol access , Including the market mainstream standard agreement national standard GB/T28181、RTMP、RTSP/Onvif Agreements, etc , And the manufacturer's private agreement , Like Haikang SDK、 Dahua SDK、 The sea, Ehome etc. . The platform can process and distribute the accessed streaming media , The video formats distributed include RTSP、RTMP、FLV、HLS、WebRTC etc. .

There's user feedback , Connect the device EasyCVR, Play RTSP There will be a jam phenomenon when flowing , I don't know why , Ask us to assist in the investigation of .

There are many reasons for video jam , For example, the network is unstable 、 Disk read / write consumption is too high 、 Memory usage is too high 、 Low server performance and so on . According to the feedback of users , Technicians immediately checked in many aspects .

Login user's EasyCVR Platform test play video , It is observed that the frame rate of the picture fluctuates , Therefore, it is preliminarily judged whether there is frame loss . Will be the original UDP The transmission protocol is changed to TCP Look again , I found that the video is still stuck . To rule out whether it is packet loss , use wireshark The bag was caught , Through packet capturing data analysis , There is no packet loss .

After the above investigation , Technicians use VLC Play it , It was found that there was no jamming , In this case, we can judge whether it is the problem of the video frame rate of the user's camera device .

Check the video frame rate of the camera device , Adjust its configuration to 25fps, stay EasyCVR Platform observation test , At this time, the video playback has been normal , There is no jam .

The higher the video frame rate, the smoother the image , The more comfortable it looks . When the frame rate of the video is lower than 25fps, The continuity and fluency of the video will decline , Image quality will also decline . Generally speaking , Set in the 25~30fps that will do .

Troubleshooting and solutions for other causes of video jam , For example, disk reading and writing consume a lot 、 Memory is abnormally occupied 、 Hard decoding, etc , We also introduced in the previous article , Interested users can read our previous articles to understand .

As the security video surveillance market is becoming more and more intelligent 、 Deepness 、 Development in the direction of integration ,EasyCVR The platform also actively expands rich video functions , Provide users with personalized demand solutions . The platform has strong expansibility 、 High openness 、 Deployment is light , Support massive video aggregation management , Support integration with third parties , Interested users can go to the demonstration platform for experience or deployment testing .
