[与此页面关联的功能（Windows Media Format 11 SDK）是一项旧功能。 它已被 源读取器 和 接收器编写器取代。 源读取器 和 接收器编写器 已针对 Windows 10 和 Windows 11 进行了优化。 Microsoft强烈建议新代码尽可能使用 源读取器 和 接收器编写器，而不是 Windows 媒体格式 11 SDK。 Microsoft建议重写使用旧 API 的现有代码，以尽可能使用新 API。]
下表按字母顺序显示此 SDK 附带的预定义属性。 每个属性都有一个名称、全局标识符和由 WMT_ATTR_DATATYPE 枚举的相应成员定义的数据类型。 某些属性不使用简单的数据类型，或根据结构设置格式。 这些属性的条目在数据类型列中列出一个结构名称，其中包含用于在括号中设置值的数据类型。
注意
有关所有 DRM 相关属性的表，请参阅 DRM 属性列表。
使用这些属性进行编程时，应使用全局标识符，而不是将名称用作字符串文本。 通过使用全局标识符，任何版式错误都将在编译时导致错误。
