How to use Java to access Youpai Cloud to implement video processing

Introduction:
Youpai Cloud is a leading domestic cloud storage and processing service provider, providing rich functions and convenient interfaces, which can Meet users' various needs for video processing. This article will introduce how to use Java language to access Youpai Cloud to implement video processing functions, and provide corresponding code examples.

1. Preparation

1. Register a Youpaiyun developer account and obtain the API key.
2. Install Java SDK.

3. Import the required Java libraries.

   import java.util.HashMap;
   import java.util.Map;

2. Video processing interface description
Youpaiyun provides a rich video processing interface, including transcoding, screenshots, watermarks, audio extraction and other functions. The following uses transcoding and screenshots as examples for explanation.

1. Video transcoding interface
   Interface name: /video/transcoding
   Function description: Transcode video files into video files of specified format and size.
   Request example:

   Map<String, String> params = new HashMap<>();
   params.put("bucket_name", "your_bucket_name");
   params.put("source", "http://your_video_url");
   params.put("notify_url", "http://your_callback_url");
   params.put("avopts", "/vf/libx265/ar_16_9/vb_500k");
   params.put("save_as", "your_save_as");

   Copy after login

2. Video screenshot interface
   Interface name: /video/thumbnail
   Function description: Screenshot the video file.
   Request example:

   Map<String, String> params = new HashMap<>();
   params.put("bucket_name", "your_bucket_name");
   params.put("notify_url", "http://your_callback_url");
   params.put("save_as", "your_save_as");
   params.put("time", "00:00:10");
   params.put("format", "jpg");

3. Java code example
The following is a sample code that uses Java language to call the Youpai Cloud video processing interface.

1. Video transcoding code example:

   public static void videoTranscoding() {
       // 创建又拍云客户端
       UpYunClient client = new UpYunClient("your_bucket_name", "your_operator_name", "your_operator_password");
   
       // 设置请求参数
       Map<String, String> params = new HashMap<>();
       params.put("source", "http://your_video_url");
       params.put("notify_url", "http://your_callback_url");
       params.put("avopts", "/vf/libx265/ar_16_9/vb_500k");
       params.put("save_as", "your_save_as");
   
       // 调用转码接口
       try {
           String result = client.request("POST", "/video/transcoding", params, null);
           System.out.println(result);
       } catch (Exception e) {
           e.printStackTrace();
       }
   }

   Copy after login

2. Video screenshot code example:

   public static void videoThumbnail() {
       // 创建又拍云客户端
       UpYunClient client = new UpYunClient("your_bucket_name", "your_operator_name", "your_operator_password");
   
       // 设置请求参数
       Map<String, String> params = new HashMap<>();
       params.put("notify_url", "http://your_callback_url");
       params.put("save_as", "your_save_as");
       params.put("time", "00:00:10");
       params.put("format", "jpg");
   
       // 调用截图接口
       try {
           String result = client.request("POST", "/video/thumbnail", params, null);
           System.out.println(result);
       } catch (Exception e) {
           e.printStackTrace();
       }
   }
