Tencent Cloud VOD and Java docking: How to implement audio and video storage and playback services?

[Introduction]
In the modern Internet era, the storage and playback of audio and video content has become one of the basic functions required by all walks of life. Tencent Cloud VOD (Video on Demand), as a powerful audio and video service provided by Tencent Cloud, provides us with flexible and reliable audio and video storage and playback solutions. This article will introduce how to use Java language to connect with Tencent Cloud VOD to implement audio and video storage and playback services.

[Step 1: Create Tencent Cloud VOD Service]
First, we need to create a VOD service on the Tencent Cloud platform. Log in to the Tencent Cloud console, enter the VOD product page, click the "Activate Now" button, and follow the prompts to successfully create a VOD service.

[Step 2: Introduce dependencies]
In our Java project, we need to introduce the SDK dependencies of Tencent Cloud VOD. We use Maven as a project management tool and add the following dependencies in the pom.xml file: 

<dependency>
    <groupId>com.tencent.cloud</groupId>
    <artifactId>vod</artifactId>
    <version>1.0.0</version>
</dependency>

Execute Maven's dependency update to successfully introduce the Tencent Cloud VOD SDK.

[Step 3: Configure key information]
In order to use Tencent Cloud VOD services, we need to configure the key information in the code. On the VOD service details page of the Tencent Cloud console, find API key management and obtain your SecretId and SecretKey.

In Java code, we can use the Credentials class to configure key information: 

import com.tencentcloudapi.common.Credential;

Credential cred = new Credential("your-secret-id", "your-secret-key");

[Step 4: Upload audio and video]
In Tencent Cloud VOD , we can upload audio and video files by calling API.

First, we need to create a VodUploadClient object and pass in the previously configured key information: 

import com.tencentcloudapi.vod.v20180717.VodClient;

VodClient client = new VodClient(cred);

Then, we can pass ApplyUploadRequest and CommitUploadRequest are used to apply for upload and submit for upload respectively. The following is a simple sample code: 

import com.tencentcloudapi.vod.v20180717.models.ApplyUploadRequest;
import com.tencentcloudapi.vod.v20180717.models.ApplyUploadResponse;
import com.tencentcloudapi.vod.v20180717.models.CommitUploadRequest;
import com.tencentcloudapi.vod.v20180717.models.CommitUploadResponse;

// 申请上传
ApplyUploadRequest applyRequest = new ApplyUploadRequest();
applyRequest.setMediaType("video");
applyRequest.setMediaName("video.mp4");

ApplyUploadResponse applyResp = client.ApplyUpload(applyRequest);
String uploadUrl = applyResp.getUploadUrl();
String tempKey = applyResp.getTempCertificate().getTmpSecretId();
String tempSecret = applyResp.getTempCertificate().getTmpSecretKey();

// 上传文件到指定URL
// ...

// 提交上传
CommitUploadRequest commitRequest = new CommitUploadRequest();
commitRequest.setVodSessionKey(uploadUrl);
commitRequest.setMediaName("video.mp4");

CommitUploadResponse commitResp = client.CommitUpload(commitRequest);
String fileId = commitResp.getFileId();

Through the above code, we can successfully upload audio and video files and obtain the fileId of the file in Tencent Cloud VOD.

[Step 5: Play audio and video]
In Tencent Cloud VOD, we can realize online playback of audio and video through the provided player. Tencent Cloud VOD provides a variety of playback methods, such as HTML5 player, mobile SDK player, etc.

The following is a sample code using the HTML5 player: 

<!DOCTYPE html>
<html>
<head>
    <title>VOD Video Player</title>
    <script src="https://vodjs.qcloud.com/v2/vodplayer.js"></script>
</head>
<body>
    <video id="video-player" src="https://playvideo.qcloud.com/getplayinfo/v2/your-file-id" controls="controls"></video>
    <script>
        var player = videoPlayer('video-player');
        player.ready();
    </script>
</body>
</html>

Save the above code as an HTML file and put https://playvideo.qcloud.com/getplayinfo/v2 Replace the your-file-id in /your-file-id with the fileId obtained from the previously uploaded audio and video.

Through the above code, we can open the HTML file in the browser to achieve online playback of audio and video files in Tencent Cloud VOD.

[Conclusion]
This article introduces in detail how to implement audio and video storage and playback services through Java code through the docking process of Java language and Tencent Cloud VOD. Through these sample codes, we can easily integrate the functions of Tencent Cloud VOD in our Java projects to provide our users with a better audio and video experience.
