Windows Media Format SDK Projects

To develop an application using the Windows Media™ Format SDK, you must use Microsoft® Visual C++® version 6.0 or later. The only programming languages appropriate for development are C++ and C.

The minimum set of header file declarations is:

#include <windows.h>
#include <wtypes.h>
#include "wmsdk.h"

The first two are standard Microsoft® Windows® header files, and the last is included with this SDK. In addition to these and any other header files and libraries the project needs, the Wmvcore.lib and WMStub.lib libraries must be linked. For more information on WMStub.lib, see Acquiring Certificates and Libraries.

To use the Windows Media Format SDK, you compile your application with the multithreaded DLL C-runtime library. To accomplish this, make the following settings under 'Project\Settings':

- 'C/C++ / Code Generation / Use run-time library' should be set to 'Multithreaded-DLL' (either Debug or not).
- 'Link / General / Ignore all default libraries' should be on.
- 'Link / General / Object/library modules' should include msvcrt.lib (or msvcrtd.lib), wmstub.lib, and wmvcore.lib. It should not include libc.lib or any variation.

Before calling any of the creation functions, COM should be initialized with a call to Coinitialize or CoinitializeEx. The free threading model can be used, although the apartment threading model can also be used though it imposes threading restrictions on the application. For more information on COM, Microsoft's Component Object Model, access the website: http:\\www.microsoft.com\com.
