创建视频解析任务
您可以通过创建MpcClient实例并设置相关参数新建视频解析任务,视频解析任务用于解析视频的元数据。
核心代码
- 创建视频解析任务。
视频解析任务需要设置输入视频文件参数,如果有必要,还可以将元数据生成文件存放在指定的路径下。

//设置解析输入视频地址和输出路径 ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("ok.mp4"); ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("output"); //创建解析请求 CreateExtractTaskRequest req = new CreateExtractTaskRequest() .withBody(new CreateExtractTaskReq().withInput(input)); // 发起请求 CreateExtractTaskResponse rsp = initMpcClient().createExtractTask(req); // 打印结果 System.out.println("CreateExtractTaskResponse=" + JsonUtils.toJSON(rsp));
