  [in]  IMFByteStream       *pOutputStream,
  [in]  IMFTranscodeProfile *pProfile,
  [out] IMFTopology         **ppTranscodeTopo
);

Parameters

[in] pSrc

A pointer to the IMFMediaSource interface of a media source. The media source provides that source content for transcoding.

[in] pOutputStream

A pointer to the IMFByteStream interface of a byte stream. The transcoded output will be written to this byte stream.

[in] pProfile

A pointer to the IMFTranscodeProfile interface of a transcoding profile.

[out] ppTranscodeTopo

Receives a pointer to the IMFTopology interface. The caller must release the interface.

Return value

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