IWMProfileManager::LoadSystemProfile 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 It has been superseded by Source Reader and Sink Writer.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 LoadSystemProfile method loads a system profile identified by its index. If you do not know the index of the desired system profile, you must use IWMProfileManager::LoadProfileByID. To load a custom profile, use IWMProfileManager::LoadProfileByData.

Syntax

HRESULT LoadSystemProfile(
  [in]  DWORD      dwProfileIndex,
  [out] IWMProfile **ppProfile
);

Parameters

[in] dwProfileIndex

DWORD containing the profile index.

[out] ppProfile

Pointer to a pointer to an IWMProfile interface.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

Because there are no system profiles for the Windows Media 9 Series codecs, this method is primarily useful for obtaining version 8 system profiles that you will convert to custom profiles using the Windows Media 9 Series codecs. For more information, see Reusing Stream Configurations.

This method can be used with GetSystemProfileCount to iterate through the system profiles.

Applications must not rely on the index of a profile (used in this call and elsewhere in the SDK) being a constant. Upgrades to the Windows Media Format components can cause these indexes to change. If an application must maintain a fixed profile, it must call IWMProfile2::GetProfileID and IWMProfileManager::LoadProfileByID.
