How PHP connects with Tencent Cloud Live Broadcast Service to achieve real-time live broadcast function

With the development of the Internet, live broadcast has gradually become a popular interactive method, and Tencent Cloud Live Broadcast Service provides powerful live broadcast functions and Stable and reliable live streaming platform. This article will introduce how to use PHP to connect to Tencent Cloud Live Broadcasting Service to realize the real-time live broadcast function.

Open Tencent Cloud Live Broadcast Service

First, we need to activate the live broadcast service on the Tencent Cloud official website. Log in to the Tencent Cloud console, select "Cloud Products", find "Live Broadcast" and activate it.

Get API key

Select "Live Broadcast" in "Cloud Products" of Tencent Cloud Console, find "Live Broadcast Console", and click "Camera Streaming" ” and enter the “API Debugging” page. The API key can be obtained on the page, which is very important for subsequent docking.

Create a push URL

Before connecting to the live streaming service, we first need to create a push URL. Tencent Cloud Live Broadcast Service provides a URL-based streaming method. We can push the video stream to the Tencent Cloud server through the URL.

The following is a sample code to generate a push URL:

<?php
$streamName = "myStream"; // 你的流名称，可以自定义
$streamKey = "yourStreamKey"; // 你的流密钥，在腾讯云控制台获取

$appId = "yourAppId"; // 在腾讯云控制台获取
$bizId = "yourBizId"; // 在腾讯云控制台获取

$currentTime = time();
$txTime = strtoupper(base_convert($currentTime + 60*60*24, 10, 16));
$url = "rtmp://$appId.livepush.myqcloud.com/live/$bizId/$streamName?txSecret=$streamKey&txTime=$txTime";
echo $url;
?>

Copy after login

Through the above code, we can generate a push URL, where $streamName is the stream name, $streamKey is the stream key, $appId is the AppId on Tencent Cloud, and $bizId is the BizId on Tencent Cloud.

Push to Tencent Cloud Server

Next, we can use PHP code to push the video stream to Tencent Cloud Server. Tencent Cloud Live Broadcast Service supports RTMP protocol and HLS protocol, and we can push the stream through the corresponding URL.

The following is a sample code for pushing a video stream:

<?php
$streamUrl = "yourStreamUrl"; // 推流URL，即上一步获取到的URL

function execCmd($cmd)
{
    $descriptorspec = array(
        0 => array("pipe", "r"),
        1 => array("pipe", "w"),
        2 => array("pipe", "w"),
    );
    $process = proc_open($cmd, $descriptorspec, $pipes);
    if (is_resource($process)) {
        fclose($pipes[0]);
        $output = stream_get_contents($pipes[1]);
        fclose($pipes[1]);
        fclose($pipes[2]);
        proc_close($process);
        return $output;
    } else {
        return false;
    }
}

$cmd = "ffmpeg -re -i input.flv -c copy -f flv $streamUrl";
execCmd($cmd);
?>

Copy after login

With the above code, we can use the FFmpeg tool to push the video stream to the Tencent Cloud server. Among them, input.flv is the video stream file to be pushed, and $streamUrl is the push URL.

Play real-time live broadcast

Finally, we can watch the real-time live broadcast through the playback address provided by Tencent Cloud Live Broadcast Service.

The following is a sample code for watching real-time live broadcast:

<!DOCTYPE html>
<html>
<head>
<title>实时直播</title>
</head>
<body>
<video src="yourPlayUrl" width="640" height="480" controls></video>
</body>
</html>

Copy after login

Through the above code, we can embed a video player on the web page, where yourPlayUrl is Tencent Cloud Live Broadcast The playback address provided by the service.

Through the above steps, we can use PHP to connect to the Tencent Cloud live broadcast service to realize the real-time live broadcast function. I hope this article will be helpful to your development, and I wish you smooth implementation of the live broadcast function.
