IWMStreamConfig2::RemoveAllDataUnitExtensions method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The RemoveAllDataUnitExtensions method removes all data unit extension systems that are associated with the stream.

Syntax

HRESULT RemoveAllDataUnitExtensions();

The method always returns S_OK.

The changes will not take effect in the profile until you call IWMProfile::ReconfigStream.
