With the development of the network, everyone has higher and higher requirements for live broadcast delay. Whether it is entertainment live broadcast, conference live broadcast or industry live broadcast, the lowest possible delay is the goal that everyone pursues. For the RTSP protocol video platform EasyNVR, many people have also asked the question of delay.
So this article intends to help you understand how to perform a delay test on the EasyNVR video platform? Let's take a look at our test steps.
Note: This delay is just to compare the stream output by the camera with the stream output by the EasyNVR platform
-
Open the online stopwatch or (mobile phone stopwatch), and point the camera at the monitor or (mobile phone)
-
Open the EasyPlayer player and fill in the rtsp address of the camera into the lower left corner of the EasyPlayer player

- Get the RTSP stream of EasyNVR
(1) Open the EasyNVR page and open the video in the channel
(2) F12 to open'Developer Mode', find'getchannels...' and double-click as shown in the figure below:
(3) In the interface below, we will modify the mode to RTSP (if you want to test streams in other formats, you can modify HLS, RTMP, FLV, etc.)
(4) After the modification is completed, we will copy the RTSP stream to EasyPlayer for playback
This stream is the RTSP stream output after the platform pulls the camera stream. After the RTSP stream of the camera and the RTSP stream output by the platform are obtained at the same time, the delay comparison is performed to check the delay time.
You can take a screenshot to view the comparison delay time at the end.
EasyNVR can output video streams in four formats, namely RTSP/RTMP/HLS/FLV. After our test, RTMP video stream is the video stream with the smallest delay at present. The theoretical delay is not affected by network bandwidth and server configuration. The minimum is only 500ms.
