Detailed explanation of the calling steps for Java to implement Youpaiyun video transcoding interface

Youpaiyun is a cloud computing company that provides cloud storage and cloud processing services. Its video transcoding interface can help users convert video files to Convert to files in different formats. This article will introduce in detail the steps of how to call Youpaiyun video transcoding interface in Java, and provide corresponding code examples.

Step 1: Add dependencies

First, we need to add relevant dependencies. In Java development, we can use Maven to manage dependencies. In the project's pom.xml file, add the following dependencies:

<dependencies>
    <dependency>
        <groupId>com.upyun</groupId>
        <<artifactId>video-process-sdk</artifactId>
        <version>1.0.0</version>
    </dependency>
</dependencies>

Step 2: Configure key information

Before calling the Youpai Cloud video transcoding interface, we need to provide a valid Key information. After registering an account and logging in on Youpaiyun's official website, you can obtain the corresponding key information in your personal center.

In the Java project, we can configure the key information in the following way:

String operator = "your_operator";
String password = "your_password";
String bucketName = "your_bucket";

Among them, operator and password are the cloud accounts. Operator and password, bucketName is the name of the bucket where the video is stored.

Step 3: Set video transcoding parameters

Before transcoding the video, we need to set the corresponding transcoding parameters. These parameters include input files, output files, transcoding types, etc. The following is an example:

TranscodeParams.Builder builder = TranscodeParams.newBuilder();
// 设置输入文件
builder.sourceFile("/path/to/input.mp4")
       // 设置输出文件
       .saveAS("/path/to/output.mp4")
       // 设置转码类型
       .avopts("acodec=aac,vcodec=libx264");
TranscodeParams transcodeParams = builder.build();

In the above example, we set the input file to "/path/to/input.mp4", the output file to "/path/to/output.mp4", and set The transcoding type is set to "acodec=aac,vcodec=libx264".

Step 4: Call the video transcoding interface

In order to use the Youpai Cloud video transcoding interface, we need to use the key information and transcoding parameters set previously. In Java, we can follow the following steps to make the call:

TranscodeService transcodeService = new TranscodeServiceImpl(operator, password, bucketName);
transcodeService.transcode(transcodeParams, new TranscodeResponseHandler() {
    @Override
    public void onSuccess() {
        // 转码成功回调
    }

    @Override
    public void onFailure(String error) {
        // 转码失败回调
    }
});

In the above code, we first create a TranscodeService object and pass in the key information set previously. Then, call the transcode method and pass in the transcoding parameters and transcoding result processor. When the transcoding is completed, if the transcoding is successful, the onSuccess callback method will be called. If the transcoding fails, the onFailure callback method will be called.

It should be noted that the call is asynchronous and the transcoding process will be performed in the background, so other operations can continue during the transcoding period.

The above are the detailed steps and corresponding code examples for calling Youpaiyun video transcoding interface using Java. Through these steps, we can easily implement video transcoding functions in Java projects to meet the needs of videos in different formats. Hope this article helps you!
