一个媒体包含一个输入文件和若干个输出文件。输入除了基本信息之外，还有详细的媒体信息。输出可以查询视频或截图的详细信息。本文为您介绍如何查询媒体详细信息。

功能使用

媒体处理支持通过SDK或API查询媒体详细信息。SDK安装请参见Java SDK、Python SDK、PHP SDK，示例代码参见下文。如需通过API使用功能，具体接口请参见直接调用API查询媒体详细信息。
说明 本文以PHP语言为例。

直接调用API查询媒体详细信息

说明 直接调用API是指直接在OpenAPI门户调用该接口请求查询媒体详细信息。
下表为查询媒体详细信息对应的接口。
功能 接口
查询媒体-使用媒体ID 查询媒体-使用媒体ID
查询媒体-使用OSS文件地址 查询媒体-使用OSS文件地址
说明 OSS文件地址指媒体文件路径。例如：http://exampleBucket****.oss-cn-hangzhou.aliyuncs.com/test/video_01.mp4。
