Creates an instance of the AC-3 media sink.
Syntax
HRESULT MFCreateAC3MediaSink(
[in] IMFByteStream *pTargetByteStream,
[in] IMFMediaType *pAudioMediaType,
[out] IMFMediaSink **ppMediaSink
);
Parameters
[in] pTargetByteStream
A pointer to the IMFByteStream interface of a byte stream. The media sink writes the AC-3 file to this byte stream. The byte stream must be writable.
[in] pAudioMediaType
A pointer to the IMFMediaType interface. This parameter specifies the media type for the AC-3 audio stream. The media type must contain the following attributes.
| Attribute | Value |
|---|---|
| MF_MT_MAJOR_TYPE | MFMediaType_Audio |
| MF_MT_SUBTYPE | MFAudioFormat_Dolby_AC3 or MFAudioFormat_Dolby_DDPlus |
[out] ppMediaSink
Receives a pointer to the IMFMediaSink interface. 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 AC-3 media sink takes compressed AC-3 audio as input and writes the audio to the byte stream without modification. The primary use for this media sink is to stream AC-3 audio over a network. The media sink does not perform AC-3 audio encoding.
