新建转码任务

您可以通过创建转码MpcClient实例并设置相关参数新建转码任务。

核心代码

  1. 创建转码MpcClient实例

    public static MpcClient initMpcClient() {
        //设置httpConfig
        HttpConfig httpConfig = HttpConfig.getDefaultHttpConfig().withIgnoreSSLVerification(true).withTimeout(3);
        //根据实际需要,是否设置http代理
        //httpConfig.withProxyHost("xxxxxx").withProxyPort(xxxxxx).withProxyUsername("xxxxxx").
                //withProxyPassword("xxxxxx");
        //根据实际填写ak,sk,华为云控制台账号名下“我的凭证”>访问密钥上创建和查看您的AK/SK
        String ak = "xxxxxx";
        String sk = "xxxxxx";
        //根据实际填写项目ID,华为云控制台账号名下“我的凭证”>API凭证下查看您的项目ID
        String projectId = "xxxxxx";
        //根据实际填写所需endpoint,这里以华东2为例
        String endpoint = "https://mpc.cn-east-2.myhuaweicloud.com";
        BasicCredentials auth = new BasicCredentials().withAk(ak).withSk(sk).withProjectId(projectId);
        return MpcClient.newBuilder()
                .withHttpConfig(httpConfig)
                .withCredential(auth)
                .withEndpoint(endpoint)
                .build();
    }
    
  2. 创建转码请求,并设置请求体
    转码请求包括输入文件、输出文件和转码模板设置。具体参数含义请参考新建转码任务

    //设置转码输入视频地址
    ObsObjInfo input = new ObsObjInfo()
        //设置桶名
        .withBucket("mpc-east-2")
        //设置OBS桶所在区域
        .withLocation("cn-east-2")
        //设置输入视频对象
        .withObject("input/ok.mp4");
    //设置转码输出视频路径
    ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2")
            //设置输出路径
            .withObject("output");
    //创建转码请求
    CreateTranscodingTaskRequest request
            = new CreateTranscodingTaskRequest().withBody(new CreateTranscodingReq()
            .withInput(input)
            .withOutput(output)
            //设置转码模板,预置模板Id可以在MPC console页面“全局设置” - “预置模板”上查看
            .withTransTemplateId(Collections.singletonList(7000530))
            //设置输出名称,名称个数需要与模板个数一一对应
            .withOutputFilenames(Collections.singletonList("output_"))
            //设置截图参数,根据实际需要填充Thumbnail结构
            //.withThumbnail(new Thumbnail())
            //设置加密参数,根据实际需要填充Encryption结构
            //.withEncryption(new Encryption())
    );
    
  3. 发送转码请求。

    //发送媒体处理服务请求
    CreateTranscodingTaskResponse response = initMpcClient().createTranscodingTask(request);
    //返回消息
    System.out.println("CreateTranscodingTaskResponse=" + response);
