Today, I will talk to you about how EasyNVR makes pull comparisons in TCP mode. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

After many modifications and improvements, the plug-free live broadcast platform of EasyNVR web page has become a mature streaming video cloud service platform, which can meet the application needs of different scenarios such as security, smart city, education and so on.

When testing EasyNVR pull, when confirming the problem with the input source, you will generally use VLC to compare the pull to test whether there is a problem with the source. The normal EasyNVR is pulled by default in TCP mode, while the VLC mode is in UDP mode, so there are differences in the results.

How EasyNVR makes pull comparison in TCP mode. Grab the package through wireshark, and the display interface is as follows:

EasyNVR:

RTP/AVP/TCP;unicast;interleaved=0-1, which means that TCP is used for streaming later.

VLC:

RTP/AVP;unicast;client_port=56940-56941 means UDP is used for streaming later, and RTP port 56940jrtcp port 56941

In order to enable VLC to use TCP for streaming, you need to modify the VLC configuration, tools-> preference configuration

Select RTP over RTSP (TCP) under input-encoder decoding, and after VLC modifies the configuration, pull the stream and grab the packet again.

After capturing the package in the image above, you can see that VLC already supports the output of the TCP stream. After EasyNVR is connected to the EasyNVS integrated video management platform, you can also obtain the VLC video stream address. For more information, please see this article: how to obtain the VLC video stream playback address in the video cloud management platform?

After reading the above, do you have any further understanding of how EasyNVR makes pull comparison in TCP mode? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
