MFCreateSourceReaderFromByteStream function
Creates the source reader from a byte stream.
Syntax
HRESULT MFCreateSourceReaderFromByteStream( _In_ IMFByteStream *pByteStream, _In_ IMFAttributes *pAttributes, _Out_ IMFSourceReader **ppSourceReader );
Parameters
- pByteStream [in]
-
A pointer to the IMFByteStream interface of a byte stream. This byte stream will provide the source data for the source reader.
- pAttributes [in]
-
Pointer to the IMFAttributes interface. You can use this parameter to configure the source reader. For more information, see Source Reader Attributes. This parameter can be NULL.
- ppSourceReader [out]
-
Receives a pointer to the IMFSourceReader 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
Call CoInitialize(Ex) and MFStartup before calling this function.
Internally, the source reader calls the IMFSourceResolver::CreateObjectFromByteStream method to create a media source from the byte stream. Therefore, a byte-stream handler must be registered for the byte stream. For more information about byte-stream handlers, see Scheme Handlers and Byte-Stream Handlers.
