How to use PHP and Youpai Cloud API to implement live streaming and playback of audio and video

Overview
In this article, we will introduce how to use PHP language and Youpai Cloud API to Realize the function of live streaming and playback of audio and video. Youpaiyun provides a rich API to help developers achieve various media processing and storage needs. We will focus on how to use Youpaiyun's live streaming and playback API, and provide relevant code examples.

1. Register Youpaiyun account and create an application
   First, we need to register a Youpaiyun account and create an application. In Youpaiyun's console, after creating an application, a specific API key and API key will be generated.
   These credentials will be used for our subsequent operations.
2. PHP script configuration
   Before we start writing PHP scripts, we first need to install the PHP development environment and ensure that the curl extension library has been installed.
   Next, create a new PHP file, name it "live.php", and add the following code to the file:

// Youpaiyun API access address
$url = "http://api.live.upyun.com/publish/";

// Youpaiyun API key
$operator = "your_operator ";
$password = "your_password";

// Request header information
$headers = array(

"Authorization: Basic " . base64_encode($operator . ':' . $password),
"Content-Type: application/json"

);

// Push streaming Address
$push_url = "rtmp://your_push_url";

// Play address
$play_url = "http://your_play_url";

// Start pushing
function start_push() {

global $url, $headers, $push_url;

$data = array(
    "url" => $push_url
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

return $result;

}

// Start playing
function start_play() {

global $url, $headers, $play_url;

$data = array(
    "url" => $play_url
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

return $result;

}

// Call the push function
$start_push_result = start_push();
echo "Push result:" . $start_push_result;

// Call the play function
$start_play_result = start_play();
echo "Play result:" . $start_play_result;

?>

Please replace "your_operator" and "your_password" in the above code with the ones you generated in Youpai Cloud Console API keys and secret keys. At the same time, replace "your_push_url" and "your_play_url" with your actual push and play addresses.

3. Run PHP script
   Save and upload the "live.php" file to a PHP server, and access the URL address of the file through the browser. PHP will automatically execute the script and call Youpaiyun's API to push streams and play audio and video.

Notes:

• Make sure that the live broadcast service has been activated in Youpaiyun's console, and the parameters related to streaming and playback are correctly configured.
• In actual use, remember to judge and process the results returned by the interface call to ensure the robustness and security of the program.

Conclusion
Through the introduction of this article, we have learned how to use the PHP language and Youpaiyun's API to implement the live streaming and playback functions of audio and video. Youpaiyun provides a rich API that can meet the various needs of developers. We can flexibly call Youpaiyun's API to implement more media processing and storage functions according to our actual needs. Hope this article is helpful to you.
