2.3 抽帧截图
2.3.1 新建截图任务
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. 创建截图任务请求。
新建截图任务请求包括输入文件、输出文件的路径。具体参数请参考新建截图任 务接口。//设置截图输入视频地址
ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2").withObject("ok.mp4");
//设置截图输出路径
ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("cn-east-2").withObject("output");
//创建截图请求
CreateThumbnailsTaskRequest req = new CreateThumbnailsTaskRequest() .withBody(new CreateThumbReq().withInput(input).withOutput(output) //设置截图类型,此处理按时间点截图
.withThumbnailPara(new ThumbnailPara().withType(ThumbnailPara.TypeEnum.DOTS) //设置截图输出文件名称
.withOutputFilename("photo") //设置截图的时间点
.withDots(Collections.singletonList(2)) //设置截图的宽
.withWidth(480) //设置截图的高 .withHeight(360)));
说明：生成的截图文件按截图时间戳命名，从首帧开始截取，中间按时间间隔截 取，最后末帧截取一张。如视频文件20s，截图间隔为11s，则生成的截图文件为 0.jpg，11.jpg，20.jpg。
2. 发送创建截图任务请求并显示返回消息。
CreateThumbnailsTaskResponse rsp = initMpcClient().createThumbnailsTask(req);
System.out.println("CreateThumbnailsTaskResponse=" + JsonUtils.toJSON(rsp));

2.3.2 取消截图任务
说明
● 取消任务需要用户提供所要取消任务的taskId。
● 待取消的taskId只能是正在截图任务队列中排队的。已开始或已完成的截图任务不 能删除。
核心代码
// 发送取消截图任务请求给媒体处理服务
DeleteThumbnailsTaskRequest req = new DeleteThumbnailsTaskRequest().withTaskId("2210744");
DeleteThumbnailsTaskResponse rsp = initMpcClient().deleteThumbnailsTask(req);
// 返回消息
System.out.println("DeleteThumbnailsTaskResponse=" + JsonUtils.toJSON(rsp));
