MFCreateMuxSink function
Creates a generic media sink that wraps a multiplexer Microsoft Media Foundation transform (MFT).
Syntax
HRESULT MFCreateMuxSink( _In_ GUID guidOutputSubType, _In_ IMFAttributes *pOutputAttributes, _In_ IMFByteStream *pOutputByteStream, _Out_ IMFMediaSink **ppMuxSink );
Parameters
- guidOutputSubType [in]
-
The subtype GUID of the output type for the MFT.
- pOutputAttributes [in]
-
A list of format attributes for the MFT output type. This parameter is optional and can be NULL.
- pOutputByteStream [in]
-
A pointer to the IMFByteStream interface of a byte stream. The output from the MFT is written to this byte stream. This parameter can be NULL.
- ppMuxSink [out]
-
Receives a pointer to the IMFMediaSink interface of the 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
This function attempts to find a multiplexer MFT that supports an output type with the following definition:
- Major type: MFMediaType_Stream
- Subtype: guidOutputSubType
- Additional format attributes (optional)
To provide a list of additional format attributes:
- Call MFCreateAttributes to get an IMFAttributes pointer.
- Use the IMFAttributes interface to set the attributes. (See Media Type Attributes.)
- Pass the IMFAttributes pointer in the pOutputAttributes parameter.
The multiplexer MFT must be registered in the MFT_CATEGORY_MULTIPLEXER category.
