IMFMediaSink::AddStreamSink method (mfidl.h)
Adds a new stream sink to the media sink.
HRESULT AddStreamSink( [in] DWORD dwStreamSinkIdentifier, [in] IMFMediaType *pMediaType, [out] IMFStreamSink **ppStreamSink );
Identifier for the new stream. The value is arbitrary but must be unique.
Pointer to the IMFMediaType interface, specifying the media type for the stream. This parameter can be NULL.
Receives a pointer to the new stream sink's IMFStreamSink interface. The caller must release the interface.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
||The method succeeded.|
||The specified stream identifier is not valid.|
||The media sink's Shutdown method has been called.|
||There is already a stream sink with the same stream identifier.|
||This media sink has a fixed set of stream sinks. New stream sinks cannot be added.|
Not all media sinks support this method. If the media sink does not support this method, the IMFMediaSink::GetCharacteristics method returns the MEDIASINK_FIXED_STREAMS flag.
