MFCreateSourceReaderFromByteStream function (mfreadwrite.h)
Creates the source reader from a byte stream.
Syntax
HRESULT MFCreateSourceReaderFromByteStream(
[in] IMFByteStream *pByteStream,
[in] IMFAttributes *pAttributes,
[out] IMFSourceReader **ppSourceReader
);
Parameters
[in] pByteStream
A pointer to the IMFByteStream interface of a byte stream. This byte stream will provide the source data for the source reader.
[in] pAttributes
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.
[out] ppSourceReader
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.
This function is available on Windows Vista if Platform Update Supplement for Windows Vista is installed.
