The information in this article applies to:

  • Microsoft Win32 Software Development Kit (SDK) versions 3.5, 3.51, 4.0
  • Microsoft Visual C++, 32-bit Edition, versions 2.0 and 2.1

SYMPTOMS

The following error is generated when you compile an application under Visual C++ version 2.0 or 2.1 that calls AVIFileCreateStream() and does not use UNICODE: 

   error C2664: 'AVIFileCreateStream' : cannot convert parameter 3 from
                'struct _AVISTREAMINFOA*' to 'struct _AVISTREAMINFOW*'

CAUSE

The Vfw.h header file from Visual C++ version 2.0 or 2.1 has the following declaration for the AVIFileCreateStream() function:

STDAPI AVIFileCreateStream(PAVIFILE pfile, 

            PAVISTREAM FAR *ppavi,
                           AVISTREAMINFOW FAR *psi);
Note the wide version of the structure in the third parameter: AVISTREAMINFOW. There is no ANSI declaration for this function in vfw.h. The header file is incorrect. It should list an ANSI version of the function that takes an ANSI AVISTREAMINFO in addition to the UNICODE version.

STATUS

Microsoft has confirmed this to be a bug in Visual C++ versions 2.0 and 2.1. This bug was corrected in Visual C++ version 2.2. The Vfw.h header file from that product declares an AVIFileCreateStreamA() function in addition to the W variety, AVIFileCreateStreamW().
