Creates an instance of the AC-3 media sink.
Syntax
HRESULT MFCreateAC3MediaSink( _In_ IMFByteStream *pTargetByteStream, _In_ IMFMediaType *pAudioMediaType, _Out_ IMFMediaSink **ppMediaSink );
Parameters
- pTargetByteStream [in]
-
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.
- pAudioMediaType [in]
-
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 - ppMediaSink [out]
-
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.
