创建转封装任务

您可以通过创建MpcClient实例并设置相关参数新建转封装任务,转封装任务用于视频转封装处理。

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。

    //设置转封装输入视频地址和输出路径
    ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2").withObject("ok.flv");
    ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2").withObject("output");
    //创建转封装请求
    CreateRemuxTaskRequest req = new CreateRemuxTaskRequest()
            .withBody(new CreateRemuxTaskReq().withInput(input).withOutput(output)
                    // 设置转封装参数
                    .withOutputParam(new RemuxOutputParam()
                            //设置转封装格式
                            .withFormat("HLS")
                            //转成hls切片间隔
                            .withSegmentDuration(5)));
    //发送转封装请求
    CreateRemuxTaskResponse rsp = initMpcClient().createRemuxTask(req);
    System.out.println(rsp.toString())
