Golang implements live broadcast

With the rapid development of the live broadcast industry, more and more people are paying attention to the implementation of live broadcast technology. In live broadcast technology, how to use golang for live broadcast is a very important issue. In this article, we will introduce how to use golang for live broadcast, and introduce in detail the advantages and implementation methods of golang.

1. Advantages of golang

Golang is an efficient, safe and reliable language for development. It is used by more and more developers because of its excellent performance and efficient concurrency. favor. In the implementation of live broadcast technology, golang has the following advantages:

1. Superior concurrency performance

In live broadcast technology, an important issue that needs to be considered is how to handle high concurrency Condition. Golang's concurrency mechanism can greatly improve the efficiency and performance of the program and greatly reduce the possibility of errors.

2. Memory Management

golang’s compiler will manage the memory of the program through the garbage collection mechanism. Therefore, for memory management problems in high concurrency situations, golang can use its own mechanism to solve it.

3. Cross-platform

Golang can run on different platforms, so it is suitable for various operating systems and can be easily transplanted and expanded.

2. Implementation of golang live broadcast

In order to use golang to implement live broadcast technology, the following steps need to be performed:

1. Design the live broadcast system architecture

When designing the live broadcast system architecture, the following points need to be clarified:

a. The source and transmission method of live broadcast data.

b. How to process and store live broadcast data.

c. How to play live data.

2. Writing a program to receive live broadcast data

The program to receive live broadcast data generally needs to be implemented using the net package in the standard library. Data from the client can be received through the listening port. , and forward the data to the live broadcast server.

3. Writing a live broadcast server program

The live broadcast server program can be implemented using the standard library that comes with golang, or you can use third-party libraries such as Go Websocket and Gin. In the live broadcast server, the storage and processing of data need to be handled, including storing the data into the database, and performing data format conversion and compression as needed.

4. Write a live broadcast client program

In the live broadcast client program, you need to use network technology to send data to the live broadcast server, and perform data format conversion and analysis as needed. In addition, you also need to use golang's graphical interface library to display and control the live broadcast screen.

5. Implement streaming media push of live broadcast data

When implementing streaming media push of live broadcast data, you need to use golang’s standard library or third-party library to implement, such as built-in HTTP library or GopherJS library, etc. Pushed data can use streaming media protocols such as HLS or RTMP.

6. Processing the distribution and load balancing of live broadcast data

When implementing the distribution and load balancing of live broadcast, you can use golang’s standard library or third-party library to achieve it, such as Zookeeper, Consul, etc. Golang uses its own goroutine for high-concurrency distribution, which can easily handle high-traffic situations.

3. Golang live broadcast application case

1. B station live broadcast system

B station uses golang to implement the backend part of the live broadcast system, including data Receiving, processing and storage, etc.

2. Miaopai Live Broadcast System

Miaopai uses golang to implement streaming media push and data distribution of the live broadcast system, which can achieve large-scale user access.

3. YY Live Broadcast System

YY Live Broadcast uses golang to implement the server side and push side of the live broadcast system, so that the live broadcast system can efficiently handle a large number of user requests and ensure that the system high reliability and performance.

4. Summary

Using golang to implement live broadcast technology can improve the performance and reliability of the program, and is suitable for issues such as high concurrency, real-time data processing, and streaming media push. In practical applications, golang has been widely used in live broadcast systems such as Bilibili, Miaopai and YY. In recent years, golang has continued to develop in the field of live broadcast technology. I believe that more companies and developers will choose golang to implement live broadcast technology.
