Privacy policy. A profile is a collection of data that describes the configuration of an ASF file. At a minimum, a profile must contain configuration settings for a single stream.
The stream information in a profile contains the bit rate, buffer window, and media properties for the stream. The stream information for audio and video describes exactly how the media is configured in the file, including which codec if any will be used to compress the data. A profile also contains information about the various ASF file features that will be used in files created with it.
Previous versions of the Windows Media Format SDK provided preconfigured system profiles, which could be used to create common types of files, or altered slightly to suit the needs of your application. System profiles are not supported for the Windows Media 9 Series codecs. This is because the number of "common" types of files has grown exponentially with the addition of new features. It is expected that virtually every content creator has needs that go beyond the simple solutions provided by system profiles.
You can still use the old system profiles as a starting place. For more information, see Using System Profiles. You must supply the writer with a profile for every file you write. Profile information can also be accessed in several ways. This can lead to confusion about what a profile is and how it is used. Profile data takes three different forms: data contained within a profile object in an application, an XML file on disk, and data in the header of an ASF file.
Each of these forms of data is shown as a shaded rectangle in the diagram. When you are editing a profile, you use a profile object, which encapsulates all of the profile data. You can create an empty profile object by using the profile manager object. You can also use the profile manager object to load existing profile data into a profile object. Most profile data must be added and manipulated through the use of objects representing individual parts of the profile.
These include stream configuration objects, mutual exclusion objects, bandwidth sharing objects, and a stream prioritization object. Each of these object types can be created using methods in the profile object. Making changes to these objects does not affect the profile object until you use a method in the profile object to include the updated data from the other object.
Profile data is stored on disk in the form of an XML file with the. System profiles are stored in a file named WMSysPr9. Note that this file actually contains no system profiles for Windows Media 9 Series because the concept of system profiles is no longer used. When you save your own custom profiles, you must save them to your own files.
