Use Workerman to build a high-performance video live broadcast platform

Abstract:
With the development of modern technology, video live broadcast has become an increasingly popular Ways of entertainment. However, live broadcast platforms need to handle a large number of concurrent connections and high bandwidth requirements, so a high-performance solution is needed. This article will introduce how to use PHP's network communication library Workerman to build a high-performance video live broadcast platform.

Introduction:
With the improvement of network bandwidth and the popularity of mobile terminal devices, live video broadcast has become a very popular form of entertainment. From live broadcast platforms, game live broadcasts to online education and other fields, the application of video live broadcasts is becoming more and more widespread. However, in the face of a large number of concurrent connections and high bandwidth requirements, how to build a high-performance video live broadcast platform has become a challenge.

Tool introduction:
Workerman is a high-performance event-driven network communication library written in PHP. It can be used to build network applications based on TCP/UDP long connections. Compared with traditional web application frameworks, Workerman has a higher number of concurrent connections and lower resource consumption.

Steps to build a live video platform:

1. Install and introduce Workerman, which can be installed through Composer.

composer require workerman/workerman

2. Create a Server class and implement onMessage, onConnect, onClose and other callback functions.

use WorkermanWorker;

// 创建一个Worker监听2345端口，使用tcp协议通信
$worker = new Worker("tcp://0.0.0.0:2345");

// 当有客户端连接时触发
$worker->onConnect = function($connection) {
    echo "Client connection
";
};

// 当接收到客户端消息时触发
$worker->onMessage = function($connection, $data) {
    echo "Received message: $data
";
};

// 当客户端连接关闭时触发
$worker->onClose = function($connection) {
    echo "Client close
";
};

// 运行Worker
Worker::runAll();

3. Start the server and listen to the specified port.

php server.php start

4. Create a client to connect to the server and send messages.

use WorkermanWorker;

// 创建一个Worker监听2345端口，使用tcp协议通信
$worker = new Worker("tcp://127.0.0.1:2345");

// 当连接建立成功时触发
$worker->onConnect = function($connection) {
    $connection->send("Hello Server!");
};

// 当接收到服务端消息时触发
$worker->onMessage = function($connection, $data) {
    echo "Received message: $data
";
};

// 当连接关闭时触发
$worker->onClose = function($connection) {
    echo "Server close
";
};

// 运行Worker
Worker::runAll();

5. Process video data streams through the API provided by Workerman, such as broadcasting video data to all online clients.

use WorkermanWorker;

$worker = new Worker("tcp://0.0.0.0:2345");

$worker->onConnect = function($connection) {
    echo "Client connection
";
};

$worker->onMessage = function($connection, $data) {
    broadcast($data); // 广播视频数据
};

$worker->onClose = function($connection) {
    echo "Client close
";
};

function broadcast($data) {
    global $worker;
    foreach($worker->connections as $connection) {
        $connection->send($data);
    }
}

Worker::runAll();

Summary:
By using Workerman to build a live video platform, we can get a high-performance solution. Workerman provides high concurrency and low resource consumption network communication capabilities, and is suitable for processing high-load application scenarios such as video live broadcast platforms. Through the introduction of the above code examples, we can flexibly use Workerman in actual projects to build a stable and reliable video live broadcast platform.
