新建独立加密任务

您可以通过创建MpcClient实例并设置相关参数新建独立加密任务。

前提条件

  • 已购买对象存储服务,并参考上传媒体文件在媒体处理服务同区域(如华北-北京四)上传媒体处理的源视频。
  • 已参考获取云资源授权,完成媒体处理服务授权。

核心代码

  1. 创建独立加密请求
    独立加密请求包括输入文件、输出文件和加密参数设置。

    //设置输入视频地址和输出路径
    ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2").withObject("input/hls/index.m3u8");
    ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2").withObject("output");
    //创建请求
    CreateEncryptTaskRequest req = new CreateEncryptTaskRequest()
            .withBody(new CreateEncryptReq().withInput(input).withOutput(output)
                    .withEncryption(new Encryption().withHlsEncrypt(new HlsEncrypt()
                            // 设置加密算法
                            .withAlgorithm("AES-128-CBC")
                            // 密钥获取服务的地址
                            .withUrl("www.xxxxx.com")
                            // 设置初始向量
                            .withIv("xxxxxxxxxxxxxxxxxxx")
                            // 设置Key
                            .withKey("xxxxxxxxxxxxxxxxxxxxxx"))));
    //向转码服务发送请求                        
    CreateEncryptTaskResponse rsp = initMpcClient().createEncryptTask(req);
    //打印返回消息
    System.out.println("CreateEncryptTaskResponse=" + JsonUtils.toJSON(rsp));
