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.
