What are the main streaming media technologies used in the development of live video software?

In the development of live video software system, streaming media technology mainly includes the following contents:

1, intelligent traffic technology

Automatically detect network conditions, adjust the attributes of audio and video to the best, and let users receive media streams matching their network speed, thus obtaining the best user experience.

2. Split technology

Generally, it is only used in the development of live video system. The sending server sends the media stream to multiple receiving servers distributed all over the country, and the client can access the server nearby to obtain a higher quality media stream and reduce the bandwidth occupation. Streaming media is the process of pushing live content to the server; Pull stream is the process of pulling the existing live broadcast content of the server with the specified address.

3. Cache technology

In order to solve the problem of packet disorder caused by network asynchrony, network delay and jitter, firstly, the packet is cached locally, and the cache system uses the ring linked list structure to discard the broadcast content to prevent cache overflow.

4. Content Distribution Network (CDN) technology

A content overlay network based on IP network, by introducing active content management, global load balancing, content caching and other technologies, publishes streaming media content requested by users to the edge of the network nearest to users, thus providing response speed and reducing the pressure on the backbone network.
