MFCreateMP3MediaSink function (mfidl.h)

Creates the MP3 media sink.

Syntax

HRESULT MFCreateMP3MediaSink(
  [in]  IMFByteStream *pTargetByteStream,
  [out] IMFMediaSink  **ppMediaSink
);

Parameters

[in] pTargetByteStream

A pointer to the IMFByteStream interface of a byte stream. The media sink writes the MP3 file to this byte stream. The byte stream must be writable.

[out] ppMediaSink

Receives a pointer to the IMFMediaSink interface of the MP3 media sink.. The caller must release the interface.

Return value

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The MP3 media sink takes compressed MP3 audio samples as input, and writes an MP3 file with ID3 headers as output. The MP3 media sink does not perform MP3 audio encoding.

Examples

HRESULT CreateMP3Sink(PCWSTR pszOutputFile, IMFMediaSink **ppSink)
{
    *ppSink = NULL;

    IMFByteStream* pStream = NULL;

    // Create a byte stream for the output file.
    HRESULT hr =  MFCreateFile(
        MF_ACCESSMODE_WRITE, 
        MF_OPENMODE_DELETE_IF_EXIST, 
        MF_FILEFLAGS_NONE, 
        pszOutputFile, 
        &pStream
        );
       
    // Create the MP3 media sink.
    if (SUCCEEDED(hr))
    {
        hr =  MFCreateMP3MediaSink(pStream, ppSink);
    }

    SafeRelease(&pStream);
    return hr;
}
