DirectShow Attributes (Compact 2013)

3/26/2014

An attribute is a single item of metadata. Most of the attributes can be set by your application and are written to the header of an ASF file.

Some predefined attributes are coded attributes. These attributes are not stored in the header of an Advanced Streaming Format (ASF) file, but are computed by the objects of the Windows Media Format SDK when the file is loaded. Because coded attributes are always computed, they are read-only.

This SDK includes many attribute definitions that you can use. You can also create attributes of your own to describe content.

The following sections describe the predefined attributes.
