Workerman 개발: UDP 프로토콜을 기반으로 비디오 스트리밍을 구현하는 방법

use WorkermanWorker;
$udpWorker = new Worker("udp://0.0.0.0:1234");

$udpWorker->onMessage = function($connection, $data){
    // 广播数据包给其他客户端
    foreach($udpWorker->connections as $clientConnection){
        $clientConnection->send($data);
    }
};

$spspps = ""; // SPS和PPS数据
$file = fopen("video.mp4", "rb");
while(!feof($file)){ // 从文件中读取数据并进行编码
    $data = fread($file, 4096);
    $encodedData = encode($data, $spspps);
    $udpWorker->send($encodedData);
}

function encode($data, &$spspps){
    $encodedData = "";
    // 进行H.264编码处理

    // 获取SPS和PPS数据
    if($spspps == ""){
        $pos1 = strpos($encodedData, "
g");
        $pos2 = strpos($encodedData, "
h");
        $spspps = substr($encodedData, 0, $pos2);
    }

    // 添加SPS和PPS数据到每个关键帧帧首
    if(substr($encodedData, 0, 4) == "
e"){
        $encodedData = $spspps . $encodedData;
    }

    return $encodedData;
}

fclose($file);

use WorkermanWorker;

// 创建Udp客户端对象
$client = new Worker("udp://127.0.0.1:1234");

// 启动客户端，建立连接
$client->onWorkerStart = function(){
    global $client;
