IConfigAsfWriter interface
The IConfigAsfWriter interface is implemented by the DirectShow WM ASF Writer filter and provides methods for getting and setting the profiles and indexing mode. The filter uses the profile to determine how many input pins to create, and what media types to accept at connection time. When the WM ASF Writer filter is first created, it is configured automatically with the following default profile: WMProfile_V80_256Video. (Use of this profile is not recommended because it does not use the Windows Media Audio and Video 9 Series codecs.)
