简介

数据万象提供了一套完善便捷的媒体处理机制，通过这套机制可以对存储在对象存储 COS 中的媒体对象进行各类型处理操作。
媒体处理机制分为以下几种方式：
方式
类别
说明
通过裸参数提交任务
持久化处理
提交媒体处理任务，并在提交任务时设置好 媒体处理任务所需参数。
通过模板设置提交任务
持久化处理
于提交媒体处理任务前设置好处理模板，并在提交任务 选择所需模板。
工作流处理
持久化处理
可将不同的任务类型组合成为工作流，将工作流设置好并开启工作流后，上传 COS 后的文件会 自动触发工作流处理流程。
批量处理
持久化处理
针对 COS 上已经存在的数据进行批量处理，处理方式与提交任务类似，确认需要处理的数据范围与处理类型后 提交批量任务。
同步任务
同步处理
在媒体对象的 URL 后加上 媒体处理参数。

通过裸参数提交任务

您可以在每次提交媒体处理任务时，灵活地配置 媒体处理任务所需参数。
说明
通过裸参数提交任务时不需要设置模板。
