IFileSinkFilter::SetFileName method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The SetFileName method sets the name of the file into which media samples will be written.
Syntax
HRESULT SetFileName(
[in] LPCOLESTR pszFileName,
[in] const AM_MEDIA_TYPE *pmt
);
Parameters
[in] pszFileName
Pointer to the name of the file to receive the media samples.
[in] pmt
Pointer to the type of media samples to be written to the file, and the media type of the sink filter's input pin.
Return value
Returns an HRESULT value.
Remarks
If the pszFileName parameter names a nonexistent file, the file will be created. If it names an existing file, the sink filter will overwrite the file without first deleting it.
