Core Code

1. Create MPC configuration items.
   These configuration items are used for MPC to obtain authorization. Table 1 describes the parameters.

   1 2 3 4 5

   MpcConfig mpcConfig = new MpcConfig(); mpcConfig.setEndPoint(endPoint);// Set the endpoint. mpcConfig.setProjectId(projectId);// Set the project ID. mpcConfig.setSk(sk);// Set the SK. mpcConfig.setAk(ak);// Set the AK.

   Table 1 MPC parameters

   Parameter	Type	Description
   endPoint	String	Endpoint. The endpoint of MPC is mts.cn-north-4.myhuaweicloud.com. Replace cn-north-4 with the value of region in the address box of the browser after you select MPC on the management console.
   ProjectId	String	Project ID. For details, see Obtaining a Project ID and Account Name.
   ak	String	Access key ID (AK). For details, see Obtaining the AK/SK Pair.
   sk	String	Secret Access Key (SK) used together with the AK. For details, see Obtaining the AK/SK Pair.

2. Create an MpcClient instance.

   If no proxy server is configured, you can directly create an MpcClient instance.

   1 2	// Create an MpcClient instance. MpcClient mpcClient = new MpcClient(mpcConfig);

   If a proxy server needs to be configured, set proxy parameters and then transfer the proxy as a constructor to the MpcClient instance.

   1 2 3 4 5 6 7 8

   // Configure the proxy. ClientConfig clientConfig = new ClientConfig(); clientConfig.setProxyHost(proxyHost);// Set the IP address of the proxy server. clientConfig.setProxyPort(Integer.parseInt(proxyPort));// Set the port number of the proxy server. clientConfig.setProxyUserName(proxyUserName);// Set the username for accessing the proxy server. clientConfig.setProxyPassword(proxyPassword);// Set the password for accessing the proxy server. // Use the constructor to initialize MpcClient. MpcClient mpcClient =new MpcClient(mpcConfig, clientConfig);

3. Send a request.

   1 2	// Set request parameters. UpdateWatermarkTemplateRequest updateWatermarkTemplateRequest = new UpdateWatermarkTemplateRequest();

4. Set template parameters.

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

   // Set the watermark template ID. updateWatermarkTemplateRequest.setTemplateId("template_id"); // Set the watermark template name. updateWatermarkTemplateRequest.setTemplateName("template_name"); // Set the watermark type. updateWatermarkTemplateRequest.setType("Image"); // Set how the image watermark is processed. updateWatermarkTemplateRequest.setImageProcess("Original"); // Set the watermark image width. updateWatermarkTemplateRequest.setWidth("20"); // Set the watermark image height. updateWatermarkTemplateRequest.setHeight("30"); // Set the horizontal offset of the watermark image relative to the output video. The default value is 0. updateWatermarkTemplateRequest.setDx("20"); // Set the vertical offset of the watermark image relative to the output video. updateWatermarkTemplateRequest.setDy("30"); // Set the watermark position. The options are TopRight, TopLeft, BottomRight, and BottomLeft. updateWatermarkTemplateRequest.setReferpos("TopRight"); // Set the watermark start time. updateWatermarkTemplateRequest.setTimelineStart("10"); // Set the watermark duration. The default value is ToEND. updateWatermarkTemplateRequest.setTimelineDuration("ToEND");

5. Send a request for modifying a watermark template and return a message.

   1 2 3 4 5

   // Send a request to MPC. BaseResponse baseResponse = mpcClient.updateWatermarkTemplate(updateWatermarkTemplateRequest); // Return a message. System.out.println(new Gson().toJson(baseResponse));
