How to use Java and Youpai Cloud to build an audio streaming service

With the popularity of audio streaming, more and more developers have begun to pay attention to how to build a stable and efficient audio streaming service. This article will introduce how to use the Java programming language and Youpai Cloud to build an audio streaming service, and attach sample code.

Youpaiyun is a world-leading cloud storage and content distribution network service provider, and also has rich experience and technical support in the field of audio streaming media. We can use Youpaiyun's audio processing capabilities to implement audio streaming services.

First, we need to create an audio processing template on Youpai Cloud and configure it to the format required by the audio streaming service. Common audio streaming formats can be selected, such as MP3, AAC, etc. Log in to the Youpai Cloud console, find the "Audio Processing" module, click "Create Template", and follow the interface instructions to create an audio processing template.

Next, we need to write Java code to interact with Youpaiyun. Youpaiyun provides a rich Java SDK, and we can use the various functions it provides by introducing the SDK's Jar package.

First of all, we need to configure the account information of Youpaiyun. In Java code, you can configure it in the following way:

UPYunConfig.setApiKey("your_api_key");
UPYunConfig.setBucketName("your_bucket_name");

Among them, your_api_key is the API Key of Youpaiyun account, your_bucket_name is the space for storing audio files name.

Next, we can write code to implement audio uploading and transcoding. Suppose we want to upload an audio file named audio.mp3 and transcode it to AAC format, the code is as follows:

UPYun upyun = new UPYun();
upyun.setTimeout(30);
upyun.setApiDomain(UPYunConfig.API_DOMAIN);
upyun.setSericeName(UPYunConfig.SERVICE_NAME);
upyun.setOperator(UPYunConfig.OPERATOR_NAME, UPYunConfig.OPERATOR_PASSWORD);

File file = new File("audio.mp3");
String saveKey = "/audio.aac";

// 上传音频文件
upyun.writeFile(saveKey, file, true);

// 发起音频转码请求
upyun.avResumeTranscode(saveKey, "aac");

// 获取转码状态
while (true) {
    TranscodeStatus status = upyun.getAvTranscodeStatus(saveKey);
    if (status.isSuccess()) {
        break;
    } else if (status.isFailed()) {
        // 转码失败，处理相应的逻辑
        break;
    }

    Thread.sleep(5000);
}

// 获取转码后的音频地址
String transcodeUrl = upyun.getAvTranscodeResult(saveKey);

In the code, we pass upyun. The writeFile() method uploads audio files, and uses the upyun.avResumeTranscode() method to initiate an audio transcoding request. Then, use the upyun.getAvTranscodeStatus() method to get the transcoding status until the transcoding succeeds or fails. Finally, use the upyun.getAvTranscodeResult() method to obtain the transcoded audio address.

Through the above steps, we can implement an audio streaming service built using Java and Youpai Cloud. We can return the transcoded audio address to the front end, and the front end implements audio streaming by accessing the address.

To sum up, this article introduces how to use Java and Youpai Cloud to build an audio streaming service, and provides corresponding sample code. I hope readers can implement their own audio streaming services through the introduction and sample code of this article.
